Radiation prophylaxis as primary prevention of heterotopic ossification of the knee: classification of disease and indications for treatment

摘要

Objective Heterotopic ossification (HO) of the knee joint is seen in up to 42 % of patients following total knee arthroplasty (TKA). Despite this prevalence, there is a paucity of data to validate the efficacy and after effects of prophylactic radiotherapy (PRT) to the knee to prevent HO. We report retrospectively our institution’s experience with 12 patients treated with PRT of the knee joint. We also present a classification scheme and review the indications for PRT following TKA.
