Background: Background Prophylactic radiation therapy (RT) is an established adjuvant therapy for heterotopic ossification (HO) of the hip when delivered in the immediate pre- or post-operative setting. Its role in prevention of recurrence after excision of HO is supported by randomized trials for HO of the hip, but there is scant evidence to support a similar approach in non-hip joints. In the current study, we evaluate radiologic and functional outcomes after prophylactic radiation therapy (RT) for prevention of HO of the knee and upper extremity [elbow and metacarpophalangeal (MCP) joints].
