The UniSpacer: a treatment alternative for the middle-aged patient.
The UniSpacer is a metallic tibial hemiarthroplasty for treatment of isolated osteoarthritis of the medial compartment of the joint. It is a mobile-bearing, self-centering shim that is introduced into the knee through a limited medial arthrotomy without requiring bone cuts or fixation to the tibia or femur. Clinical data are now available that define the efficacy of the procedure in addition to defining the ideal clinical setting for its use in the treatment of osteoarthritis of the medial compartment of the knee.
