…In summary, unicompartmental knee arthroplasty remains an excellent treatment alternative for osteoarthritis confined to the medial or lateral part of the knee joint. Fixed-bearing implants have been shown to provide good pain relief and restoration of function, and have reproducibly demonstrated excellent survivorship into the second decade. This author makes the case for a fixed-bearing over a mobile-bearing implant because they are technically easier, avoid the complication of bearing dislocation, are more versatile, and less expensive.
