Abstract |
Background |
Returning to high-impact sport is an increasingly frequent functional demand following hip replacement. The literature, however, is sparse on the subject and nonexistent regarding triathlon. We therefore conducted a retrospective study of hip resurfacing in triathlon players, to determine: (1) whether it is possible to return to this kind of sport; (2) if so, whether it is possible to return to the same level; and (3) how a resurfaced hip behaves under these conditions.
Hypothesis |
Hip resurfacing allows return to competition level in long-distance triathlon.
Material and methods |
A single-center single-operator retrospective study included patients undergoing hip resurfacing with the Conserve Plus implant inserted through a posterolateral approach, who had ceased long-distance triathlon practice due to osteoarthritis of the hip. Fifty-one of the 1688 patients undergoing resurfacing during the inclusion period were long-distance triathlon players.
Results |
The series comprised 48 patients: 51 implants; 43 male, 5 female; mean age, 44.8 years (range, 28.2–58.9 years). At a mean 4.7 years’ follow-up (range, 2.2–7.6 years), all clinical scores showed significant improvement; Merle d’Aubigné and Harris scores rose respectively from 12.3 (5–16) and 42 (37–56) preoperatively to 17.5 (13–18) and 93.2 (73–100) (P<0.001). There were no cases of dislocation or implant revision. Forty-five patients returned to sport (94%). Rates of return to swimming, cycling and running were respectively 38/48 (79%), 41/48 (85%) and 33/48 (69%). Preoperatively, all patients had taken part in at least 1 competition: 29 with distance=70.3km and 19 with distance=140.6km. At follow-up, 28 patients had taken part in an Ironman competition: 21 with distance=70.3km and 7 with distance=140.6km. Mean competition performance did not differ between pre and postoperative periods.
Discussion |
Return-to-sport rates were good following hip resurfacing. Non-impact sports (swimming, cycling) predominated postoperatively, whereas the rate of impact sport (running) diminished. Return to competition-level sport (extreme triathlon) was possible for 28/48 patients (58%). Implant survival seemed unaffected by this high-impact sports activity at a mean 4.7 years’ follow-up.
Level of evidence |
IV, retrospective, non-controlled.
