Abstract |
Introduction |
The number of patients with hip or knee joint replacements is increasing. Some of these patients want to practice sport, including in high-impact sports such as ultra-trails. Is the proportion of drop-out higher among runners after a hip or knee replacement? What are the symptoms of these patients?
Hypothesis |
Hip or knee joint replacements are associated with a higher drop-out rate during an ultra-trail.
Material and methods |
We conducted a monocentric retrospective epidemiological study. A questionnaire translated into French, English and Spanish were sent to all runners registered for one or more of the 5 races of the 2015 to 2017 Ultra-Trail du Mont-Blanc® (UTMB®) editions. There were no exclusion criteria. The drop-out rate of patients who responded to the questionnaire was calculated among patients with and without hip or knee joint replacement. Specific symptoms related to these joint replacements were identified before, during and after the race.
Results |
Out of the 24,855 participants having run at least one of the 3 editions, 2,469 responded. Some of them ran several races: these 2469 runners were on 3171 start lines and 2548 finish lines (drop-out rate of 19.6%). Among these 2469 runners, 18 had hip and/or knee replacement and were on 27 start lines and 17 finish lines (drop-out rate of 37%). The race was finished by 3 of the 6 runners with a total hip arthroplasty (THA), all of the 8 runners with a hip resurfacing arthroplasty (HRA) and 3 of the 4 runners with a total knee arthroplasty (TKA). Among runners with THA, pubalgia or groin pain was described by one of them before the race, 3 during the race and 2 after the race. Among runners with HRA, pygalgia or groin pain was described by 2 of them during the race. As for the TKA, there was no specific symptom. No answering runner had a unicompartmental knee prosthesis.
Discussion |
Running ultra-trail is possible after a hip or knee joint replacement. All of the 8 runners with HRA finished the race. We may remain cautious about the long-term survival of prostheses.
Level of proof |
IV; monocentric retrospective epidemiological study.
