Medial Opening-Wedge High Tibial Osteotomy for Medial Compartment Arthrosis/Overload.

Medial opening-wedge high tibial osteotomy has become increasingly popular for treating isolated, medial compartment arthrosis in younger, more active patients. Relative indications include age younger than 55 to 60 years, normal weight, preserved range of motion, and isolated medial compartment osteoarthritis or overload. Several surgical techniques exist for stabilization of the osteotomy with similar outcomes. Complication rates after medial opening-wedge high tibial osteotomy vary from 29% to 37%, with highest risk of nonunion, fracture, stiffness, and loss of correction. Good long-term outcomes can be achieved, with 5- and 10-year survivorship rates ranging from 75% to 98.7% and 51% to 97.6%, respectively.
