Proximal or high tibial osteotomy (HTO) is a well-established procedure for managing unicompartmental osteoarthritis of the knee.1-3 Successful HTO may delay or prevent the need for eventual unicompartmental or total knee arthroplasty (TKA). However, clinical outcomes of HTO have been found to deteriorate because of progression of joint disease and pain, with arthroplasty required as a result.4-7 Up to 40% of patients require conversion to TKA 10 to 15 years after HTO.8
