Osteonecrosis of the knee - which joint preservation procedures work?
Journal of Arthroplasty 2014 January
There is no consensus with respect to the best procedures to preserve the knee joint in patients with osteonecrosis of the knee. We performed a systematic review of the literature between 1999 and 2012. Only 10 of 1057 studies met our inclusion criteria. Core decompression prevented additional surgical treatment in pre-collapse knees with a failure rate of 10.4% (7 of 67 knees). Autogenous and osteochondral grafts decreased the need for additional surgery in both pre-collapse (0%, 20 of 20) and post-collapse knees (10.5%, 8 of 76 knees). Although these results are quite promising multi-center randomized trials are needed to identify the optimal procedures to treat this disease.
