Rate of extensor mechanism complications after primary and revision knee arthroplasty reaches 12 %. Description and systematization of such complications by literature data is given. Our experience in treatment of 12 patients with such complications after primary knee and in 5 patients after revision knee arthroplasty that made up 1.0 and 13.9% of all interventions, respectively, is presented. Registered complications include para-patellar scars and ossification impingement (4), patellar lateralization (5), patellar dislocation (1), patellar tendon rupture (7). Treatment results in patients after primary arthroplasty are better than after revision intervention - 83.3 and 40% of positive results, respectively. It is shown that high rate (42.9%) of patellar tendon rupture are associated with deep periprosthetic infection. Besides, autoplasty with m. gracilis and m. semitendinosus shows its inefficiency in treatment of such complications.
