Condyle-Specific Matching Does Not Improve Midterm Clinical Outcomes of OCA Transplantation (Knee)
Purpose: To compare clinical outcomes between patients who receive size-matched orthotopic osteochondral allografts (OCAs) versus patients who are treated with non-orthotopic grafts.
- It is currently standard for many surgeons to request size and laterality matching specifications for donor condyle allografts to minimize articular incongruity
- This method often restricts the number of compatible OCA grafts available for the procedure
- 77 age, sex and chondral defect size matched patients (50 orthotopic and 27 non-orthotopic) had a mean follow-up of 4 years
- There was not a significant difference of reoperation and failure rates between the two groups
- Both groups exhibited a significant increase in SF-36, IKDC and KOOS-ADL scores
- Removing graft specifications would make more allografts readily available, shorten wait times and lead to fewer discards
JRF Ortho Take Away: There was not a significant difference in clinical outcomes between the two groups suggesting that condyle-specific matching may not be necessary.
