High prevalence of former elite ice hockey players requiring early hip arthroplasty surgery

• The high-impact nature of ice hockey puts the players at a higher risk of developing early hip osteoarthritis (OA). This study aims to evaluate the presence of cam morphology, early radiological findings of OA and total hip arthroplasty (THA) in former Swedish elite ice hockey players. Male elite ice hockey players in the highest league in Sweden seeking orthopedic consultation for hip and groin pain with restricted hip joint range of motion and subsequent radiographs (Antero/posterior view, Lauenstein view and/or Hip frontal view) were included. The radiographs were performed between 1988 and 2009 and retrospectively examined for the presence of cam morphology (evaluated by alpha-angle >= 60 degrees) and hip OA (evaluated by Tonnis classification). All players were contacted between 11 and 33 years after baseline radiograph examination for follow-up investigation of the presence of subsequent THA. A total of 44 male ice hockey players were included, of which 31 had available radiographs and 39 answered the follow-up questions. Cam morphology (alpha-angle >= 60 degrees) was present in 81% of the players. Seven players (18%) had received a THA with a mean age of 55.7 (SD 6.1) years at time of THA-surgery. Tonnis score at baseline radiographs were associated with THA later in life (P < 0.001). This study conclude that former elite Swedish ice hockey players underwent THA at a younger age than the general population. Despite confirming previous research of high prevalence of cam morphology in elite ice hockey players, no association could be established between cam morphology and the need for THA.
