HIP Surgical Techniques to Enhance Rehabilitation (HIPSTER)

The trial will assess whether the two novel robotic-assisted tendon-sparing posterior approaches to THA surgery, the PSPA and SPAIRE, improve patient outcomes in THA compared with a robotic-assisted standard PA. If successful, it is anticipated that the results of this trial will provide the evidence necessary to plan a future multicentre, randomized-controlled trial to compare the best-performing tendon-sparing approach (PSPA or SPAIRE) identified in this efficacy trial with the gold standard PA, to assess whether the efficacy results are generalizable across the NHS. At the time of the submission, the trial is currently completing recruitment, and the follow-up will be completed in 2026.
