Background: The rate of elbow medial ulnar collateral ligament (MUCL) injury and surgery continues to rise steadily. While authors have failed to reach a consensus on the optimal graft or anchor configuration for MUCL reconstruction, the vast majority of the literature is focused on the young, elite athlete population utilizing autograft. These studies may not be as applicable for the “weekend warrior” type of patient or for young kids playing on high school leagues or recreationally without the intent or aspiration to participate at an elite level. Purpose: To investigate the clinical outcomes and complication rates of MUCL reconstruction utilizing only allograft sources in nonelite athletes. Study Design: Case series; Level of evidence, 4. Methods: Patient records were retrospectively analyzed for individuals who underwent allograft MUCL reconstruction at a single institution between 2000 and 2016. A total of 25 patients met inclusion criteria as laborers or nonelite (not collegiate or professional) athletes with a minimum of 2 years of postoperative follow-up. A review of the medical records for the included patients was performed to determine survivorship free of reoperation, complications, and clinical outcomes with use of the Summary Outcome Determination (SOD) and Timmerman-Andrews scores. Statistical analysis included a Wilcoxon rank-sum test to compare continuous variables between groups with an alpha level set at .05 for significance. Subgroup analysis included comparing outcome scores based on the allograft type used. Results: Twenty-five patients met all inclusion and exclusion criteria. The mean time to follow-up was 91 months (range, 25-195 months), and the mean age at the time of surgery was 25 years (range, 12-65 years). There were no revision operations for recurrent instability. The mean SOD score was 9 (range, 5-10) at the most recent follow-up, and the Timmerman-Andrews scores averaged 97 (range, 80-100). Three patients underwent subsequent surgical procedures for ulnar neuropathy (n = 2) and contracture (n = 1), and 1 patient underwent surgical intervention for combined ulnar neuropathy and contracture. Conclusion: Allograft MUCL reconstruction in nonelite athletes demonstrates comparable functional scores with many previously reported autograft outcomes in elite athletes. These results may be informative for elbow surgeons who wish to avoid autograft morbidity in common laborers and nonelite athletes with MUCL incompetency.

ImportanceTears of the ulnar collateral ligament (UCL) of the elbow occur predominantly as an overuse injury, most commonly affecting throwing athletes, particularly baseball players. UCL reconstruction (UCLR) has been described as an effective treatment modality in the short term.ObjectiveThe purpose of this study was to systematically review the evidence in the literature to ascertain the clinical outcomes, complication and revision rates in baseball players following UCLR of the elbow at a minimum of 48 months of follow-up.Evidence reviewTwo independent reviewers performed a search of the literature based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the EMBASE, PubMed and Scopus databases. Clinical studies were included if they reported outcomes of baseball players at a minimum of 48 months following UCLR.FindingsOur review included 8 studies including 1104 baseball players (1105 elbows) at mean 69.9 months (48–205) following UCLR. The majority of baseball players were pitchers (92.3%), with a mean age of 22.2 years (13–42). At final follow-up, the overall return to play (RTP) was 95.3%%, with 85.3% returning at pre-injury level. In addition, the mean reported Conway-Jobe score was 86.8%, the revision rate was 6.0% with postoperative neuropathy reported in 2.4% of patients. A total of 479 (43.4%) were professional baseball players, with an overall RTP rate of 97.5% and 82.3% managing to RTP at their pre-injury level. The mean number of career years following UCLR was 4.7 years (0–22).Conclusion and relevanceUCLR provides excellent patient-reported and clinical outcomes to patients at medium-term follow-up with low complication and revision rates. In addition, high rates of RTP at pre-injury level and career longevity were reported by baseball players following UCLR.Level of evidenceLevel IV; Systematic Review

Background: There is no consensus on the ideal treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions without tendon damage. Purpose: To introduce a novel “retensioning technique” for arthroscopic PASTA repair and to assess the clinical and radiologic outcomes of this technique. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was performed on 24 patients whose PASTA lesion was treated using the retensioning technique between January 2011 and December 2015. The mean ± SD patient age was 57.6 ± 7.0 years (range, 43-71 years), and the mean follow-up period was 57.6 ± 23.4 months (range, 24.0-93.7 months). Sutures were placed at the edge of the PASTA lesion, tensioned, and fixed to lateral-row anchors. After surgery, shoulder range of motion (ROM) and functional scores (visual analog scale [VAS] for pain, VAS for function, American Shoulder and Elbow Surgeons [ASES] score, Constant score, Simple Shoulder Test, and Korean Shoulder Score) were evaluated at regular outpatient visits; at 6 months postoperatively, repair integrity was evaluated using magnetic resonance imaging (MRI). Results: At 12 months postoperatively, all ROM variables were improved compared with preoperative values, and shoulder abduction was improved significantly (136.00° vs 107.08°; P = .009). At final follow-up (>24 months), the VAS pain, VAS function, and ASES scores improved, from 6.39, 4.26, and 40.09 to 1.00, 8.26, and 85.96, respectively (all P < .001). At 6 months postoperatively, 21 of the 24 patients (87.5%) underwent follow-up MRI; the postoperative repair integrity was Sugaya type 1 or 2 for all of these patients, and 13 patients showed complete improvement of the lesion compared with preoperatively. Conclusion: The retensioning technique showed improved ROM and pain and functional scores as well as good tendon healing on MRI scans at 6-month follow-up in the majority of patients. Thus, the retensioning technique appears to be reliable procedure for the PASTA lesion.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle; another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Background: The number of ulnar collateral ligament (UCL) reconstructions in adolescent athletes has increased over the past 2 decades. Clinical results in this population have not been well studied. Purpose/Hypothesis: The purpose of this study was to evaluate the outcomes and return to sport after UCL reconstruction in a large group of adolescent baseball players. We hypothesized that excellent clinical outcomes and high rates of return to sport would be observed in this population at a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: We reviewed 140 adolescent (aged ≤19 years) baseball players who underwent UCL reconstruction with the American Sports Medicine Institute (ASMI) technique by a single surgeon. Medical records were reviewed for patient demographics, injury characteristics, operative details, and surgical complications. Patient-reported outcomes were assessed using the Conway scale, the Andrews-Timmerman (A-T) score, the Kerlan-Jobe Orthopaedic Clinic (KJOC) score, and a 0- to 100-point subjective scale for elbow function and satisfaction. Return to sporting activity was assessed using a custom-designed questionnaire. Results: The mean age at the time of surgery was 18.0 years (range, 13-19 years), and the mean follow-up was 57.9 months (range, 32.4-115.4 months). Over half (60%) of patients were high school athletes. The mean duration of symptoms before surgery was 6.9 months (range, 0.5-60.0 months). Partial tears were identified in 57.9% of patients, and 41.3% of patients had preoperative ulnar nerve symptoms. Graft type included the ipsilateral palmaris in 77.1% of patients. Concomitant procedures were performed in 25% of patients. Outcomes on the Conway scale were “excellent” in 86.4% of patients. The mean A-T and KJOC scores were 97.3 ± 6.1 and 85.2 ± 14.6, respectively. Mean patient satisfaction was 94.4. Overall, 97.8% of patients reported returning to sport at a mean of 11.6 months (range, 5-24 months), and 89.9% of patients returned to sport at the same level of competition or higher. A total of 11.6% of patients went on to play professional baseball. Conclusion: UCL reconstruction with the ASMI technique is an effective surgical option in adolescents, with excellent outcome scores. At a minimum of 2-year follow-up, nearly 90% of patients returned to their preinjury level of sport.

Background: Limited intermediate and no real long-term follow-up data have been published for total ankle arthroplasty (TAA) in the United States. This is a report of clinical follow-up data of a prospective, consecutive cohort of patients who underwent TAA by a single surgeon from 1999 to 2013 with the Scandinavian Total Ankle Replacement (STAR) prosthesis. Methods: Patients undergoing TAA at a single US institution were enrolled into a prospective study. These patients were followed at regular intervals with history, physical examination, and radiographs; American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale scores were obtained and recorded. Primary outcomes included implant survivability and functional outcomes scores. Secondary outcomes included perioperative complications such as periprosthetic or polyethylene fracture. Between 1999 and 2013, a total of 138 STAR TAAs were performed in 131 patients; 81 patients were female. The mean age at surgery was 61.5 ± 12.3 years (range, 30-88 years). The mean duration of follow-up for living patients who retained both initial components at final follow-up was 8.8±4.3 years (range 2-16.9 years). Results: The mean change in AOFAS Ankle-Hindfoot scores from preoperative to final follow-up was 36.0 ± 16.8 ( P < .0001). There were 21 (15.2%) implant failures that occurred at a mean 4.9 ± 4.5 years postoperation. Ten polyethylene components in 9 TAAs (6.5%) required replacement for fracture at an average 8.9 ± 3.3 years postoperatively. Fourteen patients died with their initial implants in place. Conclusion: This cohort of patients with true intermediate follow-up after TAA with the STAR prosthesis had acceptable implant survival, maintenance of improved patient-reported outcome scores, and low major complication rates. Level of Evidence: Level IV, case series.

Background: Medial ulnar collateral ligament (MUCL) repair has been proven to be effective in nonprofessional overhead-throwing athletes, with faster and higher rates of return to play (RTP) than the more traditional Tommy John reconstruction. Biomechanical studies and clinical data suggest that MUCL repair augmented with a collagen-coated internal brace may be an effective treatment option in this patient population. Purpose: To evaluate the functional outcomes of young nonprofessional athletes who underwent MUCL repair with internal brace augmentation for medial elbow instability. The hypothesis was that these patients will have high rates of RTP and improved functional outcomes. Study Design: Case series; Level of evidence, 4. Methods: Nonprofessional overhead athletes treated with MUCL repair with internal brace augmentation between 2015 and 2017 were prospectively evaluated for a minimum of 1 year. Preoperatively, all patients had evidence of medial elbow pain caused by MUCL insufficiency, as confirmed by signal changes on magnetic resonance imaging and valgus instability on arthroscopic examination. These findings did not allow them to participate in their chosen sport or profession, and each patient had failed nonoperative treatment. Postoperative outcomes were evaluated using the Overhead Athlete Shoulder and Elbow Score of the Kerlan-Jobe Orthopaedic Clinic. Complications were recorded and detailed. Results: A total of 40 nonprofessional overhead athletes were included in this study (35 men and 5 women; mean age, 17.8 years [range, 14-28 years]). The mean follow-up time was 23.8 months (range, 12-44 months). The mean postoperative Kerlan-Jobe Orthopaedic Clinic score was 92.6 (range, 64-100). Overall, 37 athletes (92.5%) returned to play or profession at the same level or higher at a mean time of 6.9 months (range, 2-12 months). Three patients did not RTP: 1 was limited by a concomitant medical diagnosis, and the other 2 chose not to resume athletics after the procedure but remained symptom free. Conclusion: In the nonprofessional athlete, primary MUCL repair with internal brace augmentation is a viable alternative to traditional repair techniques or reconstruction, allowing for a rapid RTP and promising functional outcomes.

Background: The purpose of this study was to examine the clinical outcomes and complications of patients with midfoot Charcot managed with midfoot osteotomy, realignment arthrodesis, and stabilization using intramedullary beams. Methods: Consecutive patients with midfoot Charcot treated at a tertiary-care foot and ankle center from January 2013 to July 2016 who underwent corrective osteotomy with internal beam fixation were identified; 25 patients were included in the final analysis. Patients with a minimum 1-year follow-up were evaluated with physical examination, weightbearing radiographs, and patient-reported outcome measures. The primary outcome measure was defined as restoration of a stable, plantigrade, ulcer-free foot. Median age was 58 years, median BMI was 32, and 80% were diabetic (75% insulin-dependent). Results: An ulcer-free, stable, plantigrade foot was obtained in 84% of patients. The radiographic lateral and anteroposterior Meary angle medians improved 9° and 15°, respectively, from preoperative to final postoperative weightbearing measurements ( P < .001 and P = .02). Overall, 46% of midfoot osteotomies were united on final radiographs at a median 18-month radiographic follow-up. Deep infection developed in 6 (24%) patients. The presence of a preoperative ulcer was found to be predictive of postoperative infection (P = .04); all 6 deep infections occurred in patients with preoperative ulceration. Four (16%) patients progressed to amputation at a mean 15 postoperative months, all for deep infection. Conclusion: Midfoot Charcot reconstruction with intramedullary beaming allowed for restoration of an ulcer-free, plantigrade foot in most patients, but the complication rates were high, especially in patients with preoperative ulceration. Level of Evidence: Level IV, retrospective case series.

Background: Osteochondral lesions of the talus (OLTs) involve damage to the cartilage and subchondral bone and are infrequent in children. Clinicians usually attempt nonsurgical treatment of OLTs first, and subsequently progress to surgical treatments, including retrograde drilling (RD), if the initial outcomes are insufficient. Good clinical outcomes of RD have been reported. However, the clinical outcomes of RD in skeletally immature children remain unclear, and the associated preoperative and postoperative computed tomography (CT) findings have not been reported. The purpose of this study was to evaluate the clinical outcomes and CT findings and clarify the efficacy of RD for OLTs. Methods: From January 2015 to April 2018, RD was performed on 8 ankles in 6 skeletally immature children. The patients comprised 4 boys and 2 girls with a mean age at surgery of 11.1 years. The mean follow-up was 22.8 months. The clinical outcomes were evaluated according to the Japanese Society for Surgery of the Foot (JSSF) scale. Preoperative and final follow-up CT findings were used to determine the degree of healing. Results: The mean JSSF scale in all ankles improved from 79.4 (range, 69-90) points preoperatively to 98.4 (range, 87-100) points at final follow-up ( P < .05). In the preoperative CT findings, 3 ankles had no bone fragmentation, 4 had partial bone fragmentation, and 1 had whole fragmentation. In the final follow-up CT findings, 4 ankles demonstrated good healing, 3 were fair, and 1 was poor. Conclusion: The present findings suggest that RD is an effective surgical treatment for OLTs in skeletally immature children. Level of Evidence: Level IV, retrospective case series.

Avascular necrosis of the capitate is a rare disorder of unknown aetiology that causes wrist pain and limits function. From 2009 to 2017, we performed scaphocapitolunate arthrodesis on five patients (one male, four females) with a mean age of 35 years (range 30–37) who had idiopathic avascular necrosis of the capitate. All patients had scaphocapitate and lunocapitate arthritis confirmed by arthroscopy. The mean follow-up was 5 years (range 1–9). At the latest follow-up, the mean wrist flexion–extension was 95° (versus 105° before surgery). Grip strength was 90% relative to the contralateral side. Functional scores were all significantly improved following treatment. Radiologically, fusion was achieved in all cases and there was no displacement or fracture of the bone fixation material. None of the patients had signs of midcarpal collapse or narrowing of the radiocarpal joint space. We conclude that scaphocapitolunate arthrodesis is an acceptable treatment for avascular necrosis of the capitate with midcarpal chondral lesions. It provides adequate pain relief and improves grip strength during medium-term follow-up. Level of evidence: IV

AbstractMeniscal extrusion (ME) has been identified as a risk factor in the development of knee osteoarthritis. The relevance of this finding when a meniscal scaffold is used has not been extensively studied. The objective of this study was to determine whether preoperative meniscal remnant extrusion (MRE) was correlated with postoperative scaffold extrusion (SE) or with functional outcomes at the 2-year follow-up. Retrospective study included all polyurethane scaffolds implanted with a minimum 2-year follow-up. A magnetic resonance imaging (MRI) was performed preoperatively and postoperatively at 2 years. Extrusion was measured in millimeters in a coronal view. Patients were assigned to either group 1 or 2 depending on the preoperative MRE being either <3 mm (minor extrusion) or 3 mm (major extrusion). Functional outcomes were analyzed by means of the Western Ontario Meniscal Evaluation Tool (WOMET), International Knee Documentation Committee, Kujala and Tegner scores, as well as visual analog scale. Satisfaction was also documented. Sixty-two out of 98 patients were available to undergo an MRI at final follow-up. The mean age was 41.3 years (range, 17–58) and the mean follow-up was 45 months (range, 25–69). The mean preoperative MRE was 2.8 mm (standard deviation [SD] 1.2) and the mean postoperative SE was 3.8 mm (SD 1.8) (p < 0.01). All functional scores improved during the study period. When the correlation (Spearman's rho) between the difference in extrusion between the pre 26 and postoperative periods and their correlation with the different scores was assessed, correlation was only observed in the WOMET (rho 0.61, p = 0.02). The preoperative MRE in Group 1 was 1.85 mm (SD 0.83) and 3.7 mm (SD 2.2) in Group 2 (p < 0.01). At final follow-up, SE was 3.86 mm (SD 0.7) in Group 1, whereas it was 3.98 mm (SD 1) in Group 2 (p = 0.81). No differences were observed in the scores used for these two groups. The SE observed at the 2-year follow-up after the implantation of a polyurethane scaffold did not depend on preoperative MRE (major or minor extrusion). The WOMET score, which was the only meniscal-specific functional scored used, showed some inferior results in the most extruded meniscal scaffolds. This is a retrospective case series. Level of evidence is 4.
