Return to Sport After Large Single-Surface, Multisurface, or Bipolar Osteochondral Allograft Transplantation in the Knee Using Shell Grafts

Background: Return to sport (RTS) after osteochondral allograft (OCA) transplantation for large unipolar femoral condyle defects has been consistent, but many athletes are affected by more severe lesions. Purpose: To examine outcomes for athletes who have undergone large single-surface, multisurface, or bipolar shell OCA transplantation in the knee. Study Design: Case series; Level of evidence, 4. Methods: Data from a prospective OCA transplantation registry were assessed for athletes who underwent knee transplantation for the first time (primary transplant) between June 2015 and March 2018 for injury or overuse-related articular defects. Inclusion criteria were preinjury Tegner level ≥5 and documented type and level of sport (or elite unit active military duty); in addition, patients were required to have a minimum of 1-year follow-up outcomes, including RTS data. Patient characteristics, surgery type, Tegner level, RTS, patient-reported outcome measures (PROMs), compliance with rehabilitation, revisions, and failures were assessed and compared for statistically significant differences. Results: There were 37 included athletes (mean age, 34 years; range, 15-69 years; mean body mass index, 26.2 kg/m2; range, 18-35 kg/m2) who underwent large single-surface (n = 17), multisurface (n = 4), or bipolar (n = 16) OCA transplantation. The highest preinjury median Tegner level was 9 (mean, 7.9 ± 1.7; range, 5-10). At the final follow-up, 25 patients (68%) had returned to sport; 17 (68%) returned to the same or higher level of sport compared with the highest preinjury level. The median time to RTS was 16 months (range, 7-26 months). Elite unit military, competitive collegiate, and competitive high school athletes returned at a significantly higher proportion ( P < .046) than did recreational athletes. For all patients, the Tegner level at the final follow-up (median, 6; mean, 6.1 ± 2.7; range, 1-10) was significantly lower than that at the highest preinjury level ( P = .007). PROMs were significantly improved at the final follow-up compared with preoperative levels and reached or exceeded clinically meaningful differences. OCA revisions were performed in 2 patients (5%), and failures requiring total knee arthroplasty occurred in 2 patients (5%), all of whom were recreational athletes. Noncompliance was documented in 4 athletes (11%) and was 15.5 times more likely ( P = .049) to be associated with failure or a need for revision than for compliant patients. Conclusion: Large single-surface, multisurface, or bipolar shell OCA knee transplantations in athletes resulted in two-thirds of these patients returning to sport at 16 to 24 months after transplantation. Combined, the revision and failure rates were 10%; thus, 90% of patients were considered to have successful 2- to 4-year outcomes with significant improvements in pain and function, even when patients did not RTS.

Background: Osteochondral allograft (OCA) transplantation is an integral part of the cartilage repair paradigm, but insufficient data are available regarding return to sport or recreational activity after the procedure. Purpose: The purpose of this study was to determine if athletic patients undergoing OCA transplantation returned to sport, assess reasons for not returning to sport, and ascertain patient and graft-related characteristics that differed between those who returned or did not return to sport. The secondary aims were to assess graft survivorship and patient-reported subjective outcome measures (pain, function, satisfaction) among athletic patients undergoing OCA transplantation. Study Design: Case series; Level of evidence, 4. Methods: We identified 149 knees in 142 patients who participated in sport or recreational activity before a cartilage injury (45% highly competitive athletes and 55% well-trained and frequently sporting) and underwent OCA transplantation in the knee. The mean age was 31.2 years and 58.4% were male. Information on preinjury and postoperative participation in sport or recreational activity was collected. Patients not returning to sport after OCA transplantation were mailed a questionnaire to assess why. Postoperative pain, function, and satisfaction scores were obtained, and further surgery on the operative knee was documented. Results: At a mean follow-up of 6 years, 75.2% of knees returned to sport or recreational activity. Among those who did not return to sport, knee-related issues and lifestyle changes were cited as reasons why. Patients who did not return to sport were more likely to be female, have injured their knee in an activity other than sport, and have a larger graft size. The diagnosis and anatomic location also differed. Overall, 71% of knees reported having “very good” to “excellent” function, and 79% were able to participate in a high level of activity (moderate, strenuous, or very strenuous) postoperatively. After OCA transplantation, 25.5% of knees underwent further surgery; 14 knees (9.4% of entire cohort) were considered allograft failures. Among the 135 knees that had the graft remaining in situ, pain and function improved from preoperatively to the latest follow-up on all measures, and 91% of patients were satisfied with the results of the surgery. Conclusion: OCA transplantation is a successful treatment option for athletes and highly active patients who sustain a cartilage injury to their knee. The majority of patients returned to sport or recreational activity.

Category: Ankle, Arthroscopy, Sports, Trauma Introduction/Purpose: Talar osteochondral lesion (TOCL) is a common problem in the young athletic population, mostly related to trauma. TOCL surgical treatment algorithm remains controversial, though results are improving as we gain experience. The results of TOCL surgical treatment on function and return to sport are promising, but quantified return to sport metrics remain largely unknown. Methods: A total of 156 consecutive patients following TOCL chondroplasty (10/1/2000-5/31/2018) by a single practice were retrospectively reviewed and included in this study. There were 54.5% female with a mean age 38.2 years, and mean follow-up 40.2 months following the index surgery. Patients were divided into four groups according to the type of chondroplasty performed: Antegrade arthroscopic drilling and/or microfracture (antegrade, 83 patients), retrograde arthroscopic drilling (retrograde, 35 patients), osteochondral autograft transfer (OATS, 26 patients), and allograft cartilage implantation (allograft, 12 patients). VAS scores for pain and function at the final clinic visit were collected. Patient-reported outcome measures including the short form-12 (SF-12), The Foot and Ankle Disability Index Sports Module (FADI-sports), Tegner score, Marx scale, Naal’s Sports inventory are also actively being collected. Results: Nearly 75% of patients are satisfied with surgical intervention of TOCLs. Allograft transplant was the least satisfying (71.4%), while OATS was the most satisfying (90%). Each surgical intervention yielded significantly decreased pain and increased function postoperatively (all p<0.001). Currently, 57 patients (36%) provided patient-reported outcome measures, with an average follow up of 79.8 months (Table 1). All surgical interventions trended toward decreased Tegner score, though only antegrade drilling showed a significant decrease (p<0.001). Based on Naal’s sports inventory, 85.7% of surgically treated patients reported participating in sport activities, on average 3 times/week and 50.6 minutes/session. Conclusion: Traditionally, TOCLs presented a difficult problem that is marred by unsatisfactory surgical outcomes in typically active patients. As our surgical understanding has evolved, we’ve continued to improve on outcomes. Our patients demonstrated a 74.5% satisfaction rate, a statistically significant improvement in pain and function, and a high rate of return to sport with little difference between surgical interventions at a long-term follow-up.

Abstract PurposeFocal articular cartilage injuries are common and may lead to progression of osteoarthritis. The complications associated with traditional treatment strategies have influenced the development of new biotechnologies, such as the ProChondrix® osteochondral allograft. Clinical evidence on the outcomes associated with ProChondrix® osteochondral allografts are limited. Thus, the primary purpose of this study was to evaluate the clinical outcomes following treatment of an isolated cartilage defect with a ProChondrix® osteochondral allograft implant.MethodsRetrospective analysis of patients who underwent a cartilage restoration procedure using ProChondrix® osteochondral allograft has been performed. Patients completed patient-reported outcome surveys which included the Knee injury and Osteoarthritis Outcome Score (KOOS), consisting of the 5 subscales of Pain, Symptoms, Activities of Daily Living, Sports and Recreation, and Quality of Life, the Marx Activity Scale, and the visual analog pain scale.ResultsSix patients underwent a cartilage restoration procedure using ProChondrix® between January 2016 and December 2019. Three males and three females were included with a median age of 33.5 years (range 18–48 years). The median follow-up duration was 15 months (range 9–24 months). There were 4 patellar grafts, 1 medial femoral condyle graft, and 1 lateral femoral condyle graft, with a median defect size of 18.5mm (range 13-20mm). At the most recent clinical follow-up, all six patients were pain free and all patients had returned to pre-op activity level.ConclusionTo our knowledge, this is the first study to report the clinical outcome, activity level, and patient orientated outcomes in a case series of patients following treatment of an isolated cartilage defect with a ProChondrix® osteochondral allograft implant. Our study demonstrates promising short-term results in patient reported clinical outcome scores.

Metaphyseal Fractures

Background: Fractures of the fifth metatarsal base (5th MT) are common foot injuries, but their treatment remains a subject of debate. The aim was to assess the midterm outcome of functionally treated epi-metaphyseal fractures (Lawrence and Botte types I and II) of the 5th MT. Methods: This study was a longitudinal retrospective database study with prospective follow-up. Included were all patients with an acute, isolated fracture to the 5th MT base (types I and II). All patients were treated functionally: weightbearing as tolerated without immobilization. Fracture types and fracture characteristics (displacement <2 mm/>2 mm, articular involvement, number of fragments) were assessed retrospectively. Patient-reported outcome measures (PROMs) including the visual analog scale for foot and ankle (VAS FA) and the quality-of-life score (QoL) SF-12 were collected prospectively at 2- and 5-year follow-up. Out of 95 patients, 43 patients (45%) were included with a median follow-up of 5.7 (1.5) years. Results: For both the VAS FA and SF-12, excellent scores were observed. For 30 patients (77%), longitudinal 2- and 5-year follow-up was available. No significant longitudinal changes could be observed for the VAS FA and SF-12. For both time points, neither fracture type nor characteristics significantly influenced any outcome parameter assessed. Conclusion: Functional treatment by full weightbearing and free range of motion led to excellent 5-year results for both type I and II fractures. Neither fracture location nor characteristics had a significant influence on the 5-year PROMs. Level of Evidence: Level III, comparative study.

Context: Recurrent shoulder instability in young athletes can lead to a spectrum of soft tissue and bony lesions that can be bothersome and/or disabling. Coracoid transfer is a treatment option for athletes with recurrent instability. Objective: To report the rate of return to sport for athletes after coracoid transfer. Data Sources: An electronic search of the literature was performed using the PubMed (MEDLINE) and Cochrane Databases (1966-2018). Study Selection: Studies were included if they evaluated return to sport after treatment with coracoid transfer at a minimum 1-year follow-up. Study Design: Systematic review. Level of Evidence: Level 4. Data Extraction: Data were extracted by 2 authors and included study design, level of evidence, patient demographics (number, age, sex), procedure performed, duration of clinical follow-up, rate of return to sport, patient-reported outcome measures, reoperations, and complications. Results: Fourteen studies met the inclusion criteria. The rate of return to sport at any level ranged from 80% to 100% in all but 1 study (38%), and the rate of return to the previous level of play ranged from 56% to 95% in all but 1 study (16%). Patients returned to sport at an average of 3.2 to 8.1 months. The average patient-reported outcome scores ranged from 78% to 94% (Rowe), 223.6 to 534.3 (Western Ontario Shoulder Instability Index), and 75% to 90% (subjective shoulder value). The rate of postoperative dislocation ranged from 0% to 14%, and the reoperation rate ranged from 1.4% to 13%. Conclusion: There was a high early rate of return to sport in patients who underwent coracoid transfer for anterior shoulder instability, although patients did not reliably return to the same level of play. The procedure had very favorable outcomes for treatment of instability, with low rates of recurrent dislocation and reoperation.

Background: Osteochondral allograft transplantation (OCA) is a successful knee joint preservation technique; however, the effects of defect size and defect size:condyle ratio (DSCR) are poorly understood. Purpose: To quantify clinical outcomes of isolated OCA of the knee based on defect size and DSCR. Study Design: Cohort study; Level of evidence, 3. Methods: Data from patients who underwent OCA of the knee without major concomitant procedures by a single surgeon were analyzed at a minimum follow-up of 2 years. Osteochondral defect size was measured intraoperatively, and femoral condyle size was measured with preoperative imaging. Patient-reported outcomes, reoperations, and survival rates were analyzed per defect size and DSCR, comparing males and females and patients <40 and ≥40 years old. Results: Sixty-eight patients were included, of whom 57% were male (mean ± SD: age, 34.5 ± 10.3 years; follow-up, 5.2 ± 2.6 years). Mean osteochondral defect size and DSCR were 3.48 ± 1.72 cm2 and 0.2 ± 0.1, respectively. Defect size was larger among males as compared with females (3.97 ± 1.71 cm2 vs 2.81 ± 1.16 cm2, P = .005), while DSCRs were not significantly different between sexes ( P = .609). The cohort as a whole demonstrated improvements in the following scores: Lysholm, International Knee Documentation Committee, Knee injury and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index, and 12-Item Short Form Health Survey Physical ( P < .05). There were 27 reoperations (39.7%) at a mean of 2.5 ± 1.92 years and 8 failures (11.8%) at a mean of 2.62 ± 1.3 years. Mean DCSR was higher among patients with graft failure (0.26 ± 0.20 vs 0.19 ± 0.07, P = .049). After stratification by age, failures among patients ≥40 years old were associated with a larger defect size (mean 5.37 ± 3.50 cm2 vs 3.22 ± 1.32 cm2, P = .03) and higher DSCR (mean 0.30 ± 0.25 vs 0.19 ± 0.06, P = .05) when compared with nonfailures. Failures among patients <40 years old were not significantly associated with defect size or DSCR ( P > .05) as compared with nonfailures. Conclusion: Patients undergoing isolated OCA transplantation demonstrated significant clinical improvements and a graft survival of 88.2% at 5.2 years. Failures overall were associated with a larger DSCR, and failures among patients ≥40 years old with a larger DSCR and larger defect size. Increasing defect size among males was positively correlated with some improved outcomes, although this was not maintained in analysis of the DSCR, suggesting similar prognosis after OCA regardless of sex. Clinical Relevance: Failed osteochondral allografts are associated with larger defect sizes and defect:condyle ratios in this study, providing additional information to surgeons for appropriate patient consultation.

Intramedullary Screw

Category: Ankle, Sports, Trauma Introduction/Purpose: Intramedullary screw fixation is the most common surgical intervention for treating Jones fractures and diaphyseal stress fractures of the fifth metatarsal. Proper screw placement is paramount to surgical success. There have been studies describing more traditional antegrade and retrograde approaches, dependent upon fluoroscopy and guidewires. However, we propose a novel, more efficient surgical approach that utilizes anatomical landmarks and plantarflexion angle during screw fixation. The purpose of this study was to evaluate screw position and radiographic healing parameters, return to sport, and patient-reported outcome measures after utilization of our technique for screw fixation of the fifth metatarsal fracture. Methods: This is a retrospective review from 2007 to 2017 of clinical records and radiographs of 31 consecutive patients who had fifth metatarsal fracture open reduction internal fixation using anatomical landmarks and plantarflexion angle (Johnson, Labib and Fowler 2004). The classification of the fracture, surgery time, time to union, and post-operative complications were collected. Return to sport, Tegner score, the Foot and Angle Disability Index (FADI) Sports Module, and the Short Form 12 Physical and Mental Health Composite Scale (SF-PCS/MCS) were obtained through phone interview. Post-operative X-ray analysis, including screw position and bone healing percentage, were evaluated. Post-operative screw position was described as either center-center, oblique, or cortical breach on anteroposterior, lateral or oblique view. Fisher’s exact test was used to determine the difference among frequencies of each screw position. P<0.05 was considered significant. Results: Patient and surgical information were shown in Table 1. Average post-operative follow-up was 98 (36-227) days. Screws were well center-center positioned at all three views on post-op X-ray in most cases (all p<0.001). No case showed the screw protruding into tarsometatarsal joint or cuboid impingement. Average phone interview follow-up was 5.4 (1.0-11.1) years. Tegner scores showed no difference (p=0.58) when compared between pre-injury (6.4) and current level (6.1). At the terminal follow-up, average FADI-sports was 87.2 (37.5-100), SF-PCS was 50.7 (27.3-55.6), and SF-MCS was 59.7 (52.9-67.2). In addition, 12 of 15 (80%) the college or professional athletes (1 lost to follow-up) returned to the same level sports after the surgery. Conclusion: This study quantified the benefit of a novel technique for intramedullary screw fixation of fifth metatarsal fracture that was reliable and reproducible. It facilitated accurate screw positioning, dependable union, and accompanying positive return to sport and patient-reported outcome measures.

Background: Patient reported outcome measures assess clinical progress from the patient’s perspective. This study explored the relationship between shoulder outcome measures (The Disability of the Arm, Shoulder and Hand [DASH], American Shoulder and Elbow Surgeons Standard Shoulder Assessment score [ASES], and Constant score) by comparing the best possible scores obtained in an asymptomatic population compared to overall perception of health, as measured by the SF-36 outcome measure.Methods: Volunteers (age range, 20?69 years) with asymptomatic shoulders and no history of shoulder pain, injury, surgery, imaging, or pathology (bilaterally) were included. The DASH and ASES measures were completed by 111 volunteers (72 female, 39 male), of which 92 completed the Constant score (56 female, 36 male). The SF-36 was completed by all volunteers (level of evidence: IV case series).Results: The mean (x) score for ASES measure on the right shoulder was higher for the left-hand dominant side (x=100.00 vs. 95.02, <i>p</i>-value<0.001); no other significant differences. Better SF-36 scores were associated with better DASH scores. Our prediction models suggest that perception of overall health affects the DASH scores. Sex affected all three shoulder measures scores.Conclusions: Comparing scores of shoulder outcome measures to the highest possible score is not the most informative way to interpret patient progress. Variables such as health status, sex, and hand dominance need to be considered. Furthermore, it is possible to use these variables to predict scores of outcome measures, which facilitates the healthcare provider to deliver individualized care to their patients.

Background: Conventional methods are not suitable for difficult to treat osteochondral lesions of the talus (OCLTs). The role of particulated juvenile allograft articular cartilage implantation is not well elucidated for long-term patient outcomes. Methods: Thirteen patients with difficult-to-treat OCLTs underwent arthroscopy-assisted implantation of particulated juvenile articular cartilage graft into defects from 2010 to 2012 by the same surgeon. “Difficult to treat” was defined as having at least 3 of the following features or 2 if both variables described lesion characteristics: (1) lesions size of 107 mm2 or greater, (2) shoulder lesions, (3) patients who failed microfracture, (4) patient aged ≥40 years, or (5) patient body mass index (BMI) >25. Patients were evaluated using physical examination, patient interviews, and outcome score measures. Patients had follow-up at 2 years, 4 years, and between 6 and 10 years at their most recent follow-up. Differences in functional outcome scores were compared before and after surgery. Results: Patients (age: 46.5 ± 11.8 years, BMI: 28.5 ± 6.1) had, on average, most recent follow-up of 8.0 years (range 72-113 months). Average visual analog scale for pain score decreased for patients by 3.9 points (95% confidence interval [CI] 2.18-5.60), when compared to preoperative assessment. Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscale scores also improved from 46.5 to 80.9 (95% CI 21.35-47.43), and from 18.8 to 57.9 (95% CI 21.05-57.10), respectively. Short Form–36 Health Survey physical component scores showed significant improvement by an average of 45.5 points (95% CI 32.42-58.50). American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Scale scores improved from 55.2 to 80.3 (95% CI 12.459-37.741). Conclusion: These results demonstrate positive patient-reported long-term outcomes for a cohort of patients with difficult OCLTs, followed over the course of 6-10 years after treatment with arthroscopy-assisted particulated juvenile articular cartilage implantation. Level of Evidence: Level II, prospective cohort study.

Background: Management of ankle pain in dancers can be challenging because of the repetitive stress and complex demands placed on this region. Despite the prevalence of ankle injuries in this population, literature on surgical outcomes and return to dance is limited. Purpose: To retrospectively evaluate the efficacy and functional outcomes after surgical excision of a symptomatic os trigonum in dancers. Study Design: Case series; Level of evidence, 4. Methods: Between June 2006 and June 2016, a total of 44 dancers underwent surgical excision of a symptomatic os trigonum at a single institution and by a single surgeon. All patients presented with symptoms of posterior ankle impingement syndrome and subsequently failed nonsurgical treatment. Clinical analysis was conducted using various pre- and postoperative patient-reported outcome questionnaires, including the Veterans RAND 12-Item Health Survey (VR-12), Foot Function Index–Revised (FFI-R), and visual analog scale (VAS) for pain, as well as subjective patient satisfaction. Results: A total of 44 patients (54 ankles; mean age, 18.2 years) were retrospectively evaluated at a mean follow-up of 33.4 months. The VR-12 Physical Health score improved from a mean score of 37.8 ± 11.9 to 51.2 ± 10.5 ( P < .001). The cumulative FFI-R score improved from 46.45 ± 13.8 to 31.2 ± 9.7 ( P = .044), with the subcategory of “activity limitation” representing the highest-scoring FFI-R subcategory at 65.28 ± 13.4 preoperatively and improving to 34.47 ± 12.4 at follow-up ( P < .001). The mean VAS score for subjective pain improved significantly from 5.39 ± 2.84 to 1.73 ± 2.10 ( P < .00044). Conclusion: Overall, the findings of the present study demonstrate that dancers of varying style and level improved significantly according to various clinical measures. Patients included in this study reported that they returned to their previous level of dance upon completion of physical therapy and maintained thriving postoperative careers, which for several meant dancing at the professional level.
