Background:Bone marrow stimulation (BMS) is a common surgical intervention in the treatment of small osteochondral lesions of the talus (OLTs). Evidence has shown good clinical outcomes after BMS in the short term, but several studies have shown less favorable results at midterm and long-term follow-up because of fibrocartilaginous repair tissue degeneration.Purpose:To evaluate the clinical and radiological outcomes of BMS in the treatment of primary OLTs at midterm and long-term follow-up and to investigate reported data in these studies.Study Design:Systematic review; Level of evidence, 4.Methods:A systematic search of the MEDLINE, Embase, and Cochrane Library databases was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical and radiological outcomes as well as reported data were evaluated.Results:A total of 15 studies comprising 853 patients (858 ankles) were included at a weighted mean follow-up time of 71.9 months. There were 9 studies that used the American Orthopaedic Foot & Ankle Society (AOFAS) score, with a weighted mean postoperative score of 89.9. There were 3 studies that measured postoperative magnetic resonance imaging results in the midterm using the MOCART (magnetic resonance observation of cartilage repair tissue) scoring system and showed 48% of patients with complete filling, 74% with complete integration, and 76% with surface damage. There was a complication rate of 3.4% and a reoperation rate of 6.0% after BMS in the midterm.Conclusion:This systematic review found good clinical outcomes after BMS at midterm follow-up for primary OLTs. Radiological outcomes showed repair tissue surface damage in the majority of patients, which may be a harbinger for long-term problems. Data were variable, and numerous data were underreported. Further high-quality studies, a validated outcome scoring system, and further radiological reports at midterm follow-up are required to accurately assess the success of BMS in the midterm.
Purpose The purpose of this study is to evaluate the reasons why athletes do not return to play (RTP) following anterior cruciate ligament (ACL) reconstruction from a large single-centre database. Methods The institutional ACL registry was screened for patients that had undergone a primary ACLR and had RTP status reported at 24-month follow-up. The reasons that patients were unable to RTP at 24 months were evaluated. The ACL-Return to Sport Index (ACL-RSI) was evaluated at baseline and 24-month follow-up to evaluate psychological ability to RTP. Results At 2 years, 1140 patients returned to play, and 222 had not returned to play. The most common reasons athletes were unable to return was fear of reinjury (27.5%), lack of conidence in performance on return (19.4%) and external life factors (16.6%), i.e. work commitments and family reasons. Other reasons for athletes not returning to play were residual knee pain (10%) and subsequent injury (5%). The ACL-RSI score was signiicantly lower at diagnosis (40.3 vs. 49.3; p = 0.003) and 2 years (41.8 vs. 78.7; p < 0.0001) in athletes who did not return to play vs. those that did RTP.
ConclusionThe majority of patients that report they have not returned to play do so due to external life and psychological factors associated with their injury, including fear of reinjury and lack of conidence in performance. A small minority of patients were unable to return due to residual knee symptoms or reinjury. Pre-operative psychological assessment and intervention may identify those less likely to RTP and provide an opportunity for targeted interventions to further improve RTP outcomes. Level of evidence III.
