[Surgical treatment of knee osteoarthritis].

Surgery for knee osteoarthritis is indicated if the clinical subjective symptoms in conjunction with radiological findings can no longer be adequately treated by conservative measures. Fundamentally, the treatment procedures are differentiated between joint preserving interventions (arthroscopy, knee revision, if necessary with meniscal debridement, partial synovectomy, osteophyte removal, cartilage surgery with microfracturing, autologous chrondrocyte transplantation, mosaic plasty or spacer implantation), corrective osteotomies near the knee joint and joint replacing procedures (knee endoprostheses or knee fusion [arthrodesis]).
