An interventional study of Surgical reconstruction of gluteus medius with Achilles tendon allograft in Arthroplasty Complications, Muscle Weakness and Muscle Atrophy, sponsored by Sahlgrenska University Hospital. Recruiting at 1 site in Sweden. Open to participants aged 40 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-04-08.
Sponsored by Sahlgrenska University Hospital · Not applicable, Interventional, and Treatment
Residual limping after total hip arthroplasty is a serious complication that lacks effective treatment. The purpose of this study is to evaluate a surgical treatment for residual limping and compare its results with non-surgical treatment. Our hypothesis is that surgical treatment followed by physiotherapy increases hip function and reduces limping compared with non-surgical treatment with physiotherapy alone.
Residual limping due to gluteus medius insufficiency after total hip arthroplasty is a serious complication that lacks effective treatment. The purpose of this study is to evaluate surgical reconstruction of gluteus medius using Achilles tendon allograft and compare its results and adverse events with non-surgical treatment. Our hypothesis is that surgical reconstruction followed by physiotherapy increases hip function and reduces limping compared with non-surgical treatment with physiotherapy alone.

Exclusion Criteria:
22 patients undergo surgical reconstruction of gluteus medius with allograft consisting of Achilles tendon with calcaneus block. The calcaneus block is fixed into the greater trochanter and the Achilles tendon i passed through the gluteus medius muscle, tensioned and sutured into the muscle. Postoperatively, partial weight bearing for 2 months followed by physiotherapy for 10 months.
Procedure: Surgical reconstruction of gluteus medius with Achilles tendon allograft
22 patients receive non-operative treatment for their limp with physiotherapy alone during a 12-month period.
Achilles tendon allograft i fixed between the gluteus medius muscle and the greater trochanter
Also known as: Homologous Achilles tendon transplant, Gastrocnemius tendon allograft

Started Jun 2022 (actual). Primary completion is estimated for Dec 2027, 66 months after the start.
Of 200 non-industry interventional studies with no phase under Muscle Weakness, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's planned 66 months is above that.
Counting every sponsor, half of 212 studies reached it within 12 months; a quarter within 5 and three quarters within 28.
