Return to Sports and Return to Work After Total Hip Arthroplasty: A Systematic Review and Meta-analysis.

Abstract

Return to work (RTW) and sports (RTS) are critical gauges to improvement among patients after total hip arthroplasty (THA). This study aimed to determine rates, timelines, and prognostic factors associated with RTW and RTS outcomes after primary THA. A systematic review was conducted on MEDLINE, EMBASE, and CENTRAL databases with 57 studies meeting inclusion/exclusion criteria. The risk of bias was assessed using the Risk of Bias in Non-randomized Studies of Interventions and risk of bias in randomized trials (RoB2) tools. Meta-analysis and pooled analysis were conducted, with forest plots to summarize odds ratios and 95% confidence interval (CI). The pooled RTW rate across all studies was 70% (95% CI, 68%-80%), with rates varying significantly from 11% to 100%. The mean time to RTW was 11.2 weeks (range 1-27). A time point analysis showed increasing RTW rates with a maximum rate at 2 years of 90%. Increased age (p < 0.001) and preoperative heavy labor (p = 0.005) were associated with lower RTW rates. The RTS rate ranged from 42% to 100%, with a pooled rate of 85% (95% CI, 74%-92%). The mean time to RTS was 16.1 weeks (range 8-26). The RTS ranged from 20% to 80% with a pooled proportion of 56% (95% CI, 42%-70%, I2 = 90%) for high-intensity sports and from 75% to 100% for low-intensity sports with a pooled proportion of 97% (95% CI, 83-99, I2 = 93%). Most patients RTW and RTS after THA in an increasing manner as time passes with rates more than 85% after 1 year. These rates may be greatly affected by various factors, most notably age, the intensity of the sport, and the type of work performed. In general, young patients, low-demand work or sports can be resumed as soon as 4 to 6 weeks after surgery, but with increased restrictions as the intensity increases. This information should be used by practitioners to manage postoperative expectations and provide appropriate recommendations to patients. Therapeutic Level III.
