The SCBs following microfracture for OLT were not restored at midterm follow-up. There was a significant decrease of the overall SCBH score over time. Noticeably, subchondral cysts deteriorated over time consistently. In addition, the SCBH score at midterm follow-up was positively correlated with clinical outcomes. Lasting morphological changes in the SCB may be indicative of longer-term failure of the microfracture procedure.
Background: Traumatic anterior shoulder instability is a common clinical problem among athletic populations. The Latarjet procedure is a widely used treatment option to address shoulder instability in high-demand athletes at high risk of recurrence. However, rates and timing of full return to sports have not been systematically analyzed. Purpose: To systematically review the evidence in the literature to ascertain the rate and timing of return to play and the availability of specific criteria for safe return to play after the Latarjet procedure. Study Design: Systematic review. Methods: A systematic literature search was conducted based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using the EMBASE, MEDLINE, and Cochrane Library databases. Eligible for inclusion were clinical studies reporting on return to play after the Latarjet procedure. Statistical analysis was performed by use of SPSS. Results: Our review found 36 studies including 2134 cases meeting our inclusion criteria. The majority of patients were male (86.9%), with a mean age of 25.4 years (range, 15-59 years) and a mean follow-up of 83.5 months. The overall rate of return to play was 88.8%, with 72.6% returning to the same level of play. Among collision athletes, the overall rate of return to play was 88.2%, with 69.5% returning to the same level of play. In overhead athletes, the overall rate of return to play was 90.3%, with 80.6% returning to the same level of play. The mean time to return to play was 5.8 months (range, 3.2-8 months). Specific return to play criteria were reported in the majority of the studies (69.4%); time to return to sport was the most commonly reported item (66.7%). Conclusion: The overall rate of return to play was reportedly high after the Latarjet procedure. However, almost a fifth of athletes returning to sports were not able to return at the same level. Further development of validated criteria for safe return to sports could potentially improve clinical outcomes and reduce recurrence rates.
Background: Operative treatment is indicated for unstable syndesmosis injuries, and approximately 20% of all ankle fractures require operative fixation for syndesmosis injuries. Purpose: To perform a meta-analysis of randomized controlled trials evaluating clinical outcomes between suture button (SB) and syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. Study Design: Meta-analysis. Methods: A literature search was performed according to the PRISMA guidelines to identify randomized controlled trials comparing the SB and SS techniques for syndesmosis injuries. Level of evidence was assessed per the criteria of the Oxford Centre for Evidence-Based Medicine. Statistical analysis was performed with RevMan, and a P value ≤.05 was considered statistically significant. Results: Five clinical studies were identified, allowing comparison of 143 patients in the SB group with 142 patients in the SS group. Patients treated with the SB technique had a higher postoperative American Orthopaedic Foot & Ankle Society score at a mean 20.8 months (95.3 vs 86.7, P < .001). The SB group resulted in a lower rate of broken implants (0.0% vs 25.4%, P < .001), implant removal (6.0% vs 22.4%, P = .01), and joint malreduction (0.8% vs 11.5%, P = .05) as compared with the SS group. Conclusion: The SB technique results in improved functional outcomes as well as lower rates of broken implant and joint malreduction. Based on the findings of this meta-analysis, the SB technique warrants a grade A recommendation by comparison with the SS technique for the treatment of syndesmosis injuries.
Level IV, systematic review of level IV studies.
Background:The incidence of coexisting osteochondral lesions (OCLs) of the tibia and talus has been negatively correlated with successful clinical outcomes, yet these lesions have not been extensively characterized.Purpose:To determine the incidence of coexisting tibial and talar OCLs, assess the morphologic characteristics of these lesions, and evaluate whether these characteristics are predictive of outcome.Study Design:Case series; Level of evidence, 4.Methods:A total of 83 patients who underwent surgery for a talar OCL were evaluated for coexisting OCLs of the distal tibia with preoperative magnetic resonance images. Size, location, containment, International Cartilage Repair Society (ICRS) grade, patient age, and patient sex were analyzed for predictors of coexisting lesions or patient outcome. The talar and tibial surfaces were each divided into 9 zones, with 1 corresponding to the most anteromedial region and proceeding laterally and then posteriorly. The Foot and Ankle Outcome Score (FAOS) was evaluated pre- and postoperatively.Results:Twenty-six patients (31%) had coexisting tibial and talar OCLs, with 9 (35%) identified as kissing lesions. Age correlated with coexisting lesion incidence, as older patients were more likely to have a coexisting tibial OCL (P = .038). More than half of talar OCLs were found in zone 4 (61%), whereas the majority of tibial OCLs were located in zones 2, 4, and 5 (19% each). Patients with coexisting lesions were more likely to have a lateral talar OCL (P = .028), while those without a coexisting tibial lesion were more likely to have a talar OCL in zone 4 (P = .016). There was no difference in FAOS result or lesion size between patients with and without coexisting OCLs, but patients with coexisting lesions were more likely to have an ICRS grade 4 talar OCL (P = .034). For patients with coexisting lesions, kissing lesions were more likely to be located in zone 6 (P = .043). There was no difference in OCL size or containment between kissing and nonkissing coexisting OCLs.Conclusion:The incidence of coexisting talar and tibial OCLs may be more prevalent than what previous reports have suggested, with older patients being more likely to present with this pathology. The location of a talar OCL correlates with the incidence of a coexisting tibial OCL.
Background: There is a paucity of clinical studies that compare the efficacy of autograft and allograft in osteochondral transplantation for treatment of osteochondral lesions of the talus (OLT). The purpose of the present study was to compare the clinical and radiographic outcomes following osteochondral transplantation with autograft or allograft for OLT. Methods: A retrospective analysis comparing patients treated with autograft or allograft for OLT was performed. Clinical outcomes were evaluated with use of the Foot and Ankle Outcome Score (FAOS) and the Short Form-12 (SF-12) score. Magnetic resonance imaging (MRI) was evaluated with use of the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. The rates of cyst occurrence, graft degradation, graft failure, and revision surgeries were also evaluated. Results: Twenty-five nonrandomized patients with autograft and 16 with allograft were included, with a mean follow-up of 26 months in the autograft group and 22 months in the allograft group. There were no significant differences among all demographic variables between the autograft and allograft groups. The mean postoperative FAOS was significantly higher in the autograft group (81.9; 95% confidence interval [CI]: 78.6 to 85.2) than in the allograft group (70.1; 95% CI: 63.7 to 76.5; p = 0.006). Similarly, the mean postoperative SF-12 scores were significantly higher in the autograft group (74.7; 95% CI: 71.0 to 78.4) than in the allograft group (66.1; 95% CI: 61.2 to 71.0; p = 0.021). MOCART scores were significantly better in the autograft group (87.1) than in the allograft group (75.5; p = 0.005). The rate of chondral wear on MRI was higher in the allograft group (53%) than in the autograft group (4%; p < 0.001). Cyst formation in the graft itself was more likely to occur in the allograft group (47%) than in the autograft group (8%; p = 0.017). The rate of secondary procedures for the graft was higher in the allograft group (25%) than in the autograft group (0%; p = 0.009). Conclusions: In this small nonrandomized cohort study, the procedures performed with use of an autograft provided better clinical and MRI outcomes than the allograft procedures. The rate of chondral wear on MRI was higher with allograft than with autograft, and allograft-treated patients had a higher rate of clinical failure. Level of Evidence: Therapeutic Level III.
