OBJECTIVES Information about sport activity after short-stem total hip arthroplasty (THA) is scarce in the literature. We therefore aimed to evaluate the rate of return to sport after short-stem THA. METHODS We evaluated the sport pattern, rate of return to sport, activity level, extent of sport activity, and subjective rating and sense of well-being in 137 patients (137 hips) after short-stem THA. The minimum follow-up time was 18 months. All results were analyzed according to gender (male and female) and age (≤60, >60-≤70, and >70 years). RESULTS Ninety-two percent of all patients practiced sport before surgery, and 91% of the patients returned to sport. Most patients returned to sport within the first 6 months after surgery. There was a decline in the number of sport disciplines from preoperatively to postoperatively, which was from 2.9 to 2.6 (P = 0.025). High-impact activities decreased postoperatively, but most low-impact activities did not change significantly. Eighty percent of all patients were involved in recreational sports. CONCLUSION In this study, we observed an excellent rate of return to sport after short-stem THA. Most patients returned to the same level of sport activity that they had before the onset of restricting symptoms, with the majority of patients having a great sense of well-being during and after sports, and almost no pain in the affected hip.
