BACKGROUND: Since years a discussion is held on the best approach to perform total hip replacement (THR). Risk of dislocation, abductor weakness and a possible difference in rehabilitation are mentioned. We performed this study to objectify that the use of the direct anterior approach (DAA) results in a faster rehabilitation after THR compared to the non-DAA (posterolateral and anterolateral) approach. METHODS: A single centre prospective cohort study was conducted. Pre- and 16-weeks postoperative completed PROMs like the VAS, PSC, GPE and HOOS were analyzed. A leg press and power test were performed. Functional capacity was determined by the TUG and the 6MWT. RESULTS: A total of 119 patients were included for analysis: 87 in the DAA group, 32 in the non-DAA group. There were no differences in general baseline characteristics. The length of stay was significant (p = .000) shorter in the DAA group. At 16 weeks, the DAA group showed a significant greater improvement with respect to the VAS and HOOS. Also significant differences for all strength, power and functional capacity parameters between the pre- and postoperative measurements were found. A subgroup analysis at 6-weeks postoperative showed significant improvements in the TUG (p = .009) and 6MWT (p = .009) in the DAA group, but not in the non-DAA group. CONCLUSION: PROMs, strength, power and functional capacity tests show significant improvement in all approaches after THR. There seems to be a small advantage in favour of the DAA, in particular directly postoperative and the first postoperative weeks.
