Patient-Reported Outcomes and Radiographic Assessment in Primary and Revision Stage II, III, and IV Progressive Collapsing Foot Deformity Surgery

Background: Progressive collapsing foot deformity (PCFD) is a progressive hindfoot and midfoot deformity causing pain and disability. Although operative treatment is stage dependent, few studies have looked at patient-reported and radiographic outcomes stratified by primary vs revision stage II, III, and IV reconstruction surgery. Our goal was to assess operative improvement using Patient-Reported Outcomes Measurement Information System (PROMIS) and to determine whether radiographic parameter improvement correlates with patient-reported outcomes. Methods: PROMIS Physical Function (PF) and Pain Interference (PI) scores were prospectively obtained on 46 consecutive patients who underwent PCFD reconstruction between November 2013 and January 2019. Thirty-six patients completed pre- and postoperative PROMIS surveys, 6 patients completed only preoperative PROMIS surveys, and 4 patients completed 12-month postoperative PROMIS surveys but did not complete preoperative PROMIS surveys. Minimum follow-up was 12 (average, 23) months. Radiographic correction was measured with pre- and postoperative weightbearing radiographs and correlated with PROMIS scores. Measurements included the talonavicular uncoverage angle, talonavicular uncoverage percentage, anteroposterior talo–first metatarsal angle, Meary angle, medial cuneiform height (MCH), and medial cuneiform–fifth metatarsal height. Results: For the overall cohort, PROMIS PF increased significantly from 37.5±5.6 to 42.3±7.1 ( P = .0014). PROMIS PI improved significantly from 64.5±6.0 to 55.1±9.8 ( P < .0001). Preoperative, postoperative, and change in PROMIS scores were not statistically different between PCFD stages. Change in PROMIS PI was significantly greater in primary (–12.3) vs revision (–3.7) surgery ( P = .0157). Change in PROMIS PF was greater in primary (+6.0) vs revision surgery (+2.3) but did not reach statistical significance. All radiographic measurements improved significantly ( P < .05). In primary stage II PCFD, postoperative PROMIS scores correlated with postoperative MCH (PF: r = 0.7725, P = .0020; PI: r = –0.5692, P = .0446). Conclusion: Patient-reported and radiographic outcomes improved significantly after PCFD reconstruction. We found no significant difference in preoperative, postoperative, or change in PROMIS scores between PCFD stages. However, stage III patients had smaller improvements in PROMIS PF, which we feel may be secondary to change in function after arthrodesis. Primary operations had better patient-reported outcomes compared to revision operations. In primary stage II PCFD, reconstructing the medial arch height correlated significantly with improvement in pain and functionality. Level of Evidence: Level II, prospective cohort study.

Adult Acquired Flatfoot Deformity

Category: Hindfoot; Midfoot/Forefoot Introduction/Purpose: Adult-Acquired Flatfoot Deformity (AAFD) is a progressive hindfoot and midfoot deformity that causes pain and disability. It presents as a plano-valgus deformity from the failure of static and dynamic medial osteoligamentous stabilizers. Stage II presents as a passively correctable, flexible deformity of the foot; stage III presents as a fixed or arthritic deformity of the foot; and stage IV presents with marked deformity of the foot caused by failure of the deltoid ligament and subsequent peritalar instability. Although operative treatment of AAFD is dependent on the stage, there is little data on patient- reported and radiographic outcomes stratified by primary versus revision stage II, III, and IV reconstruction surgery. Methods: Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) scores were prospectively obtained on 46 consecutive patients who underwent AAFD reconstruction between November 2013 and January 2019 with minimum 12-month follow-up (average 23 months). Twenty patients underwent stage II reconstruction, 5 of which were revision surgeries; 19 patients underwent stage III reconstruction, 8 of which were revision surgeries; and 7 patients underwent stage IV reconstruction, all of which were primary surgeries. Radiographic correction was measured pre- and post-operatively and correlated with PROMIS scores. Measurements included the talonavicular uncoverage angle, talonavicular uncoverage percent, AP talo-first metatarsal angle, Meary’s angle, medial cuneiform height, and medial cuneiform-fifth metatarsal height. Results: For the overall cohort, PROMIS PF increased significantly from 37.6+-5.7 to 42.4+-6.8 (p=0.0014). PROMIS PI improved significantly from 64.7+-6.3 to 54.6+-9.5 (p<0.0001). PROMIS scores were not statistically different between AAFD stages. Change in PROMIS PI was significantly greater in primary (-12.3) versus revision (-3.7) surgery (p=0.0157). Change in PROMIS PF was non- significantly greater in primary (+4.0) versus revision surgery (+2.3). All radiographic measurements improved significantly (p<0.05). In primary stage II AAFD, pre-operative PROMIS PI scores correlated with pre-operative medial cuneiform-fifth metatarsal height (r = -0.606, p = 0.0479). In addition, in primary stage II AAFD, post-operative PROMIS scores correlated with post-operative medial cuneiform height (PROMIS PF: r=0.7725, p=0.0020; PROMIS PI: r=-0.5692, p=0.0446). Conclusion: Patient-reported and radiographic outcomes improve significantly after AAFD reconstruction. There was no significant difference in PROMIS scores between AAFD stages. However, stage III patients had non-significantly lower improvements in PROMIS PF, likely due to loss of function after arthrodesis. Primary operations had better patient-reported outcomes compared to revision operations. In primary stage II AAFD, reconstructing the medial arch correlates significantly with improvement in pain and functionality. This survey of outcomes after primary and revision stage II, III, and IV reconstruction should help clinical decision making by providing data on expected surgical improvement.

Objective The purpose of the current study is to evaluate the clinical and radiographic outcomes at early to midterm follow-up between fresh precut cores versus hemi-condylar osteochondral allograft (OCAs) in the treatment of symptomatic osteochondral lesions. Design A retrospective review of patients who underwent an OCA was performed. Patient matching between those with OCA harvested from an allograft condyle/patella or a fresh precut allograft core was performed to generate 2 comparable groups. The cartilage at the graft site was assessed with use of a modified Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system and patient-reported outcomes were collected. Results Overall, 52 total patients who underwent OCA with either fresh precut OCA cores ( n = 26) and hemi-condylar OCA ( n = 26) were pair matched at a mean follow-up of 34.0 months (range 12 months to 99 months). The mean ages were 31.5 ± 10.7 for fresh precut cores and 30.9 ± 9.8 for hemi-condylar ( P = 0.673). Males accounted for 36.4% of the overall cohort, and the mean lesion size for fresh precut OCA core was 19.6 mm2 compared to 21.2 mm2 for whole condyle ( P = 0.178). There was no significant difference in patient-reported outcomes including Visual Analogue Scale, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, and Tegner ( P > 0.5 for each), or in MOCART score (69.2 vs. 68.3, P = 0.93). Conclusions This study found that there was no difference in patient-reported clinical outcomes or MOCART scores following OCA implantation using fresh precut OCA cores or size matched condylar grafts at early to midterm follow-up.

Background: Ankle disorders in patients with rheumatoid arthritis (RA) reduce their quality of life and activities of daily living. The aim of this study was to evaluate the midterm clinical and radiographic outcomes of TAA in patients with RA. Methods: This retrospective study included patients with a minimum follow-up of 2 years. A total of 37 RA patients (39 ankles) were enrolled in this study from August 2006 to March 2016. All the patients had undergone primary cemented mobile-bearing total ankle arthroplasty (TAA). Nine ankles received arthrodesis of the subtalar joint simultaneously. Patient-reported outcomes were measured preoperatively and at the latest follow-up by Self-Administered Foot-Evaluation Questionnaire (SAFE-Q). Radiographs of the ankle were analyzed preoperatively and at all follow-up visits to measure the periprosthetic radiolucent line, migration of the tibial component, and the subsidence of the talar component. Intraoperative and postoperative complications were recorded. The average duration of follow-up for the entire cohort was 5.0 ± 2.0 years (range 2.1-10.1 years). Results: All subscales of the SAFE-Q had improved significantly at the latest follow-up. No significant difference was found between the range of motion of the ankle before and after the surgery. Radiolucent lines were observed in 28 (73.7%) ankles. Migration of the tibial component and subsidence of the talar component were found in 8 (21.1%) and 11 (28.9%) ankles, respectively. Intraoperative malleolus fractures occurred in 3 (7.7%) ankles and delayed wound healing in 10 (25.6%) ankles. Four ankles were removed because of deep infection or noninfective loosening, resulting in an implant survival rate of 88.4% (95% CI, 0.76-1.0) at 10 years. Conclusion: The midterm patient-reported outcomes and implant retention rate after cemented mobile-bearing TAA for RA patients were satisfactory. However, a low radiographic implant success rate was observed. Level of Evidence: Level IV, retrospective case series.

Category: Hindfoot, Midfoot/Forefoot Introduction/Purpose: During reconstruction of the stage II adult acquired flatfoot deformity (AAFD), residual supination of the midfoot is often addressed with an opening wedge medial cuneiform (Cotton) osteotomy after adequate correction of the hindfoot valgus deformity. The purpose of this study was to determine if there was a correlation between postoperative alignment of the medial cuneiform using the previously described cuneiform articular angle (CAA) on lateral radiographs and postoperative patient-reported outcomes using the Foot and Ankle Outcome Score (FAOS). Methods: Sixty-three feet in 61 patients with stage II AAFD who underwent a Cotton osteotomy as part of a flatfoot reconstruction were included the study. The CAA, medial arch sag angle (MASA), and lateral talo-first metatarsal (Meary’s) angles were measured on postoperative weightbearing lateral radiographs at a minimum of 40 weeks postoperatively. Pearson’s correlation analysis was used to determine if there was an association between postoperative radiographic angles and FAOS at a minimum of 24 months postoperatively. Patients were also divided into mild plantarflexion (CAA> or =-2 degrees) and moderate plantarflexion (CAA<-2 degrees) groups, and Wilcoxon rank-sum tests were used to identify whether there were differences in clinical outcomes between the two medial cuneiform positions. A postoperative CAA of -2 degrees was chosen because it is two standard deviations from the average postoperative CAA following a flatfoot reconstruction (Castaneda et al. FAI 2012). Results: Postoperative CAA was significantly positively correlated with the postoperative FAOS symptoms (r=.27, P=.03), daily activities (r=.29, P=.02), sports activities (r=.26, P=.048), and quality of life (r=.28, P=.02) subscales. A positive correlation indicates that higher postoperative FAOS scores are associated with a decreased amount of plantarflexion of the medial cuneiform (i.e. a more positive CAA). Patients in the mild plantarflexion group had statistically and clinically better outcomes compared with the moderate plantarflexion group in the FAOS symptoms (P=.04), daily activities (P =.04), and sports activities (P=.01) subscales (Figure 1). Graft size was correlated with postoperative CAA (r =-.30, P = .02) but not correlated with any postoperative FAOS subscale (all P values > .40). Conclusion: Our study suggests that the surgeon should avoid excessive plantarflexion of the medial cuneiform and use the Cotton osteotomy judiciously as part of a flatfoot reconstruction for stage II AAFD.

Category: Midfoot/Forefoot Introduction/Purpose: Midfoot arthritis is a disabling condition, causing chronic foot pain and functional disability. The goals of midfoot arthrodesis are to a plantigrade, stable, and pain-free foot. The procedure can be technically demanding and associated with a number of complications. The use of midfoot-specific plate fixation has become more popular as an alternative to screw-only fixation. The purpose of this study was to compare the clinical and radiographic outcomes following midfoot arthrodesis using different fixation methods. Methods: This was a retrospective study of all midfoot arthrodeses performed at a single institution between January 2005 and December 2014. Patients qualified if they had a minimum of 12 months follow-up, specifically with patient-reported outcomes. Demographic and surgical information were collected. Final post-operative outcomes were reviewed and consisted of patient-reported functional measures, union rate, complications, and radiographic outcomes. Patient-reported functional measures included the American Orthopedic Foot and Ankle Score (AOFAS) midfoot scale, Visual Analogue Scale (VAS) for pain, and Lower Extremity Functional Score (LEFS). Radiographic outcomes included alignment in the antero-posterior (AP) and lateral views, as measured by the talo-first metatarsal angle during the pre-operative and final follow-up visits. Outcomes were compared among the following groups: Screw fixation group (SFG), plate fixation group (PFG), and combined fixation group (CFG), which had screw and plate fixation. Results: A total of 79 midfoot fusions in 75 patients had a mean follow-up of 61 months (range 13-122) with patient-reported outcome measures. At final follow-up, the SFG had a higher median LEFS (72.5 versus 53 in the PFG and 56 in the CFG; p>0.1) and a higher mean AOFAS score (87 versus 78 in the PFG and 77 in the CFG; p>0.15). The complication and nonunion rate was highest in the PFG, with 13 (50%) and 4 (50%) cases, respectively; however, the differences were not statistically significant. The talo-first metatarsal angle improved in all three groups from a median of 6.4 degrees pre-operatively to 3.9 degrees on final post-operative imaging. Conclusion: Although not statistically significant, there was a trend towards higher patient-reported outcomes, union rate, and less complication rate in midfoot fusions treated with screw fixation compared to plate fixation and combined fixation. There was no difference in radiographic correction among the difference fixation methods. Although new techniques and implants continue to be introduced, we found no significant difference in outcomes when compared to the traditional technique of screw fixation.

Adult Acquired Flatfoot Deformity

Category: Hindfoot; Ankle; Midfoot/Forefoot Introduction/Purpose: The tibiocalcaneonavicular ligament (TCNL) is formed from the confluence of the superficial deltoid ligament and the superomedial spring ligament. In advanced flexible adult acquired flatfoot deformity (AAFD), progressive strain on the TCNL can lead to spring ligament tears, deltoid insufficiency, and eventual medial peritalar instability. Historically, medial peritalar instability was corrected using calcaneal osteotomy in conjunction with isolated spring or deltoid reconstruction. A recent study (Brodell et al.) demonstrated the efficacy of TCNL reconstruction in patients with medial peritalar instability. The purpose of this study is to add to this literature using patient-reported and radiographic outcomes in patients undergoing TCNL reconstruction. Patient-reported outcomes were collected using Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) surveys. Methods: Sixteen patients (mean age 50.25 years; 11 female, 5 male) who underwent TCNL reconstruction were prospectively identified. TCNL reconstruction was indicated for stage IIB patients (n=13) with large spring ligament tears (>1.5cm on MRI or intraoperatively) or if osseous correction did not provide adequate talonavicular joint correction. TCNL reconstruction was indicated in stage IV patients (n=3) if deltoid reconstruction required additional medial stabilization. No patients underwent lateral column lengthening osteotomies. PROMIS scores were obtained at baseline and at minimum 12-months follow-up (average 16 months). Surgical success was determined using minimum clinically important differences (MCID), defined as improvement greater than one-half the standard deviation of each pre-operative PROMIS domain (PF: +2.9 and PI: -2.5). Pre- and post-operative radiographic parameters were measured: talonavicular uncoverage angle, talonavicular uncoverage percentage, AP talo-first metatarsal angle, Meary’s angle, and medial cuneiform height (MCH). Correlation coefficients determined the relationship between radiographic parameters and PROMIS scores. Results: PROMIS PF scores improved significantly from 38.1+-5.8 to 44.1+-7.1 (p=0.0087). PROMIS PI scores improved significantly from 62.9+-5.1 to 52.3+-8.9 (p=0.0025). Seventy-nine and 77 percent of patients had successful surgeries, as defined by MCIDs in the PROMIS PF and PI domains, respectively. Talonavicular uncoverage percentage and Meary’s angle improved significantly from 34.4+-13.4 to 26.3+-9.9 percent (p=0.0360) and 19.2+-8.8 to 15.3+-6.2 degrees (p=0.0089), respectively. Talonavicular uncoverage angle improved from 29.3+-9.6 to 23.3+-8.0 degrees (p=0.0562), AP talo-first metatarsal angle improved from 15.2+-10.2 to 10.4+-9.0 degrees (p=0.0555), and MCH improved from 13.5+-6.2 to 15.9+-4.8 millimeters (p=0.1374). Post- operative MCH correlated significantly with post-operative PROMIS PF scores (r=0.5941; p=0.0152). Change in AP talo-first metatarsal angle correlated significantly with change in PROMIS PI scores (r=0.5682; p=0.0427). No other correlations were significant. Conclusion: Patients with stage IIB and stage IV AAFD who undergo TCNL reconstructions have excellent patient-reported and radiographic outcomes. Reconstruction of the medial longitudinal arch, as measured by post-operative MCH, is associated with higher post-operative functionality. Surgical correction of midfoot abduction, as measured by change in the AP talo-first metatarsal angle after surgery, is associated with improvements in pain. In patients with medial peritalar instability, TCNL reconstruction can be a valuable technique to correct the sagittal arch, prevent excessive midfoot abduction, and improve pain and functionality.

Background Correction of talonavicular uncoverage (TNU) in adult-acquired flatfoot deformities (AAFD) can be a challenge. Lateral column lengthening (LCL) traditionally is utilized to address this. The primary study objective is examining stage II AAFD patients and determining if correction can be achieved with subtalar fusion (STF) comparable to LCL. Methods Following institutional review board approval, retrospective chart review performed identifying patients meeting criteria for stage IIB AAFD who underwent either STF with concomitant flatfoot procedures (but not LCL) to correct TNU, or who underwent LCL as part of their flatfoot reconstruction. Patients indicated for STF had one or more of the following: higher body mass index (BMI), were older, had greater deformity, lateral impingement pain, intraoperative spring ligament hyperlaxity. Patients without 1-year follow-up or compete records were excluded. All other patients were included. A total of 27 isolated STFs identified, along with 143 who underwent LCL. Pre-/postoperative radiographic parameters obtained as well as PROMIS (Patient-Reported Outcomes Measurement Information System) and FAOS (Foot and Ankle Outcome Score) scores. Radiographic and patient reported outcomes both preoperatively and at 1-year follow-up evaluated for both groups. Results STF patients were older ( P < .05), with higher BMIs ( P < .004). STF had significantly worse TNU ( P < .001) than LCL patients, and average change in STF TNU was larger than LCL change postoperatively ( P = .006), after adjusting for age, BMI, gender. PROMIS STF improvement reached statistical significance in Physical Function (P 0.011), for FAOS Pain (P 0.025) and Function ( P = 0.04). Conclusions STF can be used in appropriately indicated patients to correct flatfoot deformity without compromising radiographic or clinical, correcting not only hindfoot valgus, but also talonavicular uncoverage (TNU) and corresponding medial arch collapse.

Metatarsus Adductus

Abstract Background Zones 2 and 3 fifth metatarsal fractures are often treated with intramedullary fixation due to an increased risk of nonunion. A previous 3-dimensional (3D) computerized tomography (CT) imaging study by our group determined that the screw should stop short of the bow of the metatarsal and be larger than the commonly used 4.5 millimeter (mm) screw. This study determines how these guidelines translate to operative outcomes, measured using Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) surveys. Radiographic variables measuring the height of the medial longitudinal arch and degree of metatarsus adductus were also obtained to determine if these measurements had any effect on outcomes. And lastly, this study aimed to determine if morphologic differences between males and females affected surgical outcomes. Methods We retrospectively identified 23 patients (14 male, 9 female) who met inclusion criteria. Eighteen patients completed PROMIS surveys. Preoperative PROMIS surveys were completed prior to surgery, rather than retroactively. Weightbearing radiographs were also obtained preoperatively to assist with surgical planning and postoperatively to assess interval healing. Correlation coefficients were calculated between PROMIS scores and repair characteristics (hardware characteristics [screw length and diameter] and radiographic measurements of specific morphometric features). T tests determined the relationship between repair characteristics, PROMIS scores, and incidence of operative complications. PROMIS scores and correlation coefficients were also stratified by gender. Results The average screw length and diameter adhered to guidelines from our previous study. Preoperatively, mean PROMIS PI = 57.26±11.03 and PROMIS PF = 42.27±15.45 after injury. Postoperatively, PROMIS PI = 44.15±7.36 and PROMIS PF = 57.22±10.93. Patients with complications had significantly worse postoperative PROMIS PF scores (p=0.0151) and PROMIS PI scores (p=0.003) compared to patients without complications. Females had non-significantly worse preoperative and postoperative PROMIS scores compared to males and had a higher complication rate (33 percent versus 21 percent, respectively). Metatarsus adductus angle was shown to exhibit a significant moderate inverse relationship with postoperative PROMIS PF scores in the overall cohort (r=−0.478; p=0.045). Metatarsus adductus angle (r=−0.606; p=0.008), lateral talo-1st metatarsal angle (r=−0.592; p=0.01), and medial cuneiform height (r=−0.529; p=0.024) demonstrated significant inverse relationships with change in PROMIS PF scores for the overall cohort. Within the male subcohort, significant relationships were found between the change in PROMIS PF and metatarsus adductus angle (r=−0.7526; p=0.005), lateral talo-1st metatarsal angle (r=−0.7539; p=0.005), and medial cuneiform height (r=−0.627; p=0.029). Conclusion Patients treated according to guidelines from our prior study achieved satisfactory patient reported and radiographic outcomes. Screws larger than 4.5mm did not lead to hardware complications, including screw failure, iatrogenic fractures, or cortical blowouts. Females had non-significantly lower preoperative and postoperative PROMIS scores and were more likely to suffer complications compared to males. Patients with complications, higher arched feet, or greater metatarsus adductus angles had worse functional outcomes. Future studies should better characterize whether patients with excessive lateral column loading benefit from an off-loading cavus orthotic or plantar-lateral plating.

Metatarsus Adductus

Category: Midfoot/Forefoot; Trauma Introduction/Purpose: Proximal (zone 2 and 3) fifth metatarsal fractures are common fractures. Due to poor blood supply, these fractures are generally treated operatively due to an increased risk of nonunion. A recent study by this group used 3D CT imaging to determine guidelines for choosing the optimal screw. The study found that the screw length should stop short of the bow of the metatarsal and the screw diameter should be larger than the commonly used 4.5 mm screw to ensure endosteal fixation. The purpose of this study is to determine how well these guidelines translate to surgical outcomes, measured using Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) surveys. Methods: A retrospective review yielded 24 patients with zone 2 or 3 fractures between 2013 and 2016. Twenty-three patients met inclusion criteria and 18 patients completed preoperative and postoperative PROMIS PF and PI surveys. Radiographic measurements included pitch angle, metatarsus adductus angle, AP talo-1st metatarsal angle, Meary’s angle, and medial cuneiform height. Length of the fifth metatarsal, width of the medullary canal at the bow, and distance of fracture from the proximal tip of the fifth metatarsal were also measured. Correlation coefficients were calculated between postoperative PROMIS scores and repair characteristics (radiographic measurements, screw length, and screw diameter). Correlation coefficients were also calculated comparing change in PROMIS scores from preoperative baseline and repair characteristics. T-tests were used to determine the relationship between repair characteristics, PROMIS scores, and incidence of surgical complications - re-fractures (n=3) and non- unions (n=3). Results: The average screw parameters adhered to the guidelines established by our previous study. Average screw length was 42.17+-4.96mm and screw diameter was 5.38+-0.28mm. Preoperatively, PROMIS PI = 57.26+-11.03 and PROMIS PF = 42.27+- 15.45 after injury. Postoperatively, PROMIS PI = 44.15+-7.36 and PROMIS PF = 57.22+-10.93. Patients who had complications had significantly lower postoperative PROMIS PF scores (p=0.0432) compared to patients without complications. There was no significant difference (p>0.05) in other repair characteristics between those with and without complications. Metatarsus adductus angle (MAA) correlated inversely with postoperative PROMIS PF scores (r=-0.478; p=0.045). AP talo--1st metatarsal angle (r=- 0.611; p=0.007), medial cuneiform height (r=-0.59; p=0.01), and screw diameter (r=-0.525; p=0.025) had significant inverse relationships with change in PROMIS PF scores from baseline. Conclusion: Patients treated according to guidelines from our prior study achieved excellent outcomes as measured by PROMIS PI and PF scores. Patients with complications or excessive lateral column loading on radiograph had worse functional outcomes. Larger diameter screws may not be as important clinically as thought in radiographic/cadaveric studies, perhaps because slightly smaller diameter screws allow sufficient endosteal fixation while allowing more functionality through the metatarsal. Future studies should better characterize how screw diameter affects outcomes and whether patients with excessive lateral column loading benefit from an off-loading cavus orthotic or plantar-lateral plating.
