The importance and prevalence of osteoarthritis is increasing because of the increasing prevalence of obesity and aging of the community. Osteoarthritis is characterised by pain and joint limitation. Untreated osteoarhritis causes disability. Arthroscopic debridement, hip and knee osteotomies and arthroplasty procedures are performed for those patients in whom conservative treatment has failed. In this article, hip and knee arthroscopy, hip osteotomies and high tibial osteotomy for knee osteoarthritis are discussed as treatment options for non-arthroplastic surgeries.
