Unicondylar Knee Arthroplasty in Patellectomized Patients

Brauns J

In patellectomized patients, the change of extensor mechanism of the knee and the increase of antero-posterior laxity can enhance the risk of femorotibial arthrosis in non-arthrotic knees and worsen the mechanical conditions in preexcisting osteoarthritis. Several treatment options had been studies, with mixed clinical results. There is paucity of literature on unicondylar knee arthroplasty in post-patellectomy patients with isolated antero-medial knee arthritis. Research identified six case series (23 patients). The postoperative functional outcome was good to excellent in all reports except one, which described revision surgery of all three patients. After this review we conclude unicondylar knee arthroplasty may be a good treatment option in patellectomized patient with isolated antero-medial gonarthrosis.
