Cayenne Medical announced the preliminary two-year results of its study evaluating the Mirror Partial Knee System.
The partial knee replacement system uses the patient's natural knee motion to position implants while balancing the knee. The retrospective study examined 100 consecutive partial knee implants and Knee Society Pain Scores and Oxford Scores were evaluated for the patients.
The study found that 94 percent were satisfied, 93 percent reported improved function and 93 percent reported decreased pain. One knee was converted to a total knee replacement due to persistent pain.
