Patellofemoral Osteoarthritis: Partial Lateral Patellar Facetectomy
Partial lateral facetectomy is a relatively easy and efficacious surgical treatment for middle-aged to elderly active patients with isolated lateral patellofemoral osteoarthritis (OA) who require pain relief and maintenance of level of activity but who wish to avoid arthroplasty. It can be performed arthroscopically or open. The indications are isolated patellofemoral OA in patients with an overhanging lateral facet of the patella with anterolateral knee pain and lack of response to conservative treatment. A satisfactory outcome after lateral patellar facetectomy for isolated patellofemoral OA can be foreseen in about half of the cases at 10 years follow-up; patellofemoral arthroplasty (PFA) or total knee arthroplasty (TKA) may be performed with no special considerations in patients who do not achieve adequate pain relief following partial lateral facetectomy.
