Know you options
Unicompartmental knee replacements are far more common on the medial (closest to the midline) compartment but are done on the lateral also. Uni's are still common but not all surgeons perform them nor should. There are several factors considered whether or not a uni is an option. If there are arthritic changes in either of the other 2 compartments, you are headed for a total knee replacement. Your orthopedist can evaluate this. Most orthopedic company's websites will help you search for a surgeon that performs certain procedures. One of the more prominent uni's is the Oxford, developed in the UK 30yrs ago and distributed by Biomet, Inc. It's mobile bearing design is the only like it. Other companies offering uni's: Zimmer, Depuy, Smith & Nephew, etc. Do the research, educate yourself and good luck!
