Abstract:
Tibial hemiarthroplasty using the UniSpacer Knee System is a viable treatment alternative for knee osteoarthritis of the medial compartment. Improvements in patient selection, surgical technique, and rehabilitation continue to improve results. In contrast to alternative procedures, implantation of the UniSpacer Knee System preserves the natural knee anatomy therefore future knee procedures are not compromised. The early results suggest that the UniSpacer Knee System is a complementary alternative to other treatment options.
