Knee replacement - partial

Unicompartmental knee arthroplasty may be considered in patients with the following conditions:

• Osteoarthritis of the knee
• Knee deformity
• Refractory osteomalacia
• Avascular and aseptic necrosis

Patients age 60 and up who are not physically active and who have no history of inflammatory arthritis are good candidates for this procedure. UKA is not recommended for patients who engage in heavy work or sports, are obese, or have significant ligament problems.
