Spearman correlation could not demonstrate a correlation between joint space and cartilage damage (⍴Acetabular = 0.10, ⍴Femoral Head = 0.04). Interestingly, a gradual widening was observed between the medial and lateral joint spaces, with more pronounced findings in hips without damage. CONCLUSION The results of this study demonstrate that in patients with Tönnis 0 and 1, narrower joint space cannot predict actual intraoperative cartilage damage. However, if the lateral joint space has relative narrowing compared to the medial joint space, this may indicate acetabular cartilage damage. PURPOSE To systematically evaluate outcomes and complications of osteochondral autograft transfer (OAT) and osteochondral allograft transplantation (OCA) for the surgical treatment of capitellar osteochondritis dissecans (OCD). METHODS A literature search was conducted across 3 databases (PubMed, Cochrane, CINAHL) from database inception through December of 2019 in accordance with the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Individual study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) scale. Studies were published between 2005 and 2019. RESULTS Eighteen studies consisting of 446 elbow OCD lesions treated with OAT surgery were included. There was a single OCA study eligible for inclusion. Patient age ranged from 10-45 years old. 4 of the OAT studies utilized autologous costal grafts while the remainder used autografts from the knee. Outcome measures were heterogeneously reported. A significant improvement in Timmerman & Andrews (T&A) scores from pre- to post-operative was reported in 9/10 studies. Return to play (RTP) rates to the pre-injury level of competitive play ranged from 62-100% across 16 studies. Signifi
