Achilles Tendon Homograft for the Treatment of Gluteus Medius Insufficiency After Hip Replacement
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
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.

Treatments
Experimental: Surgical reconstruction
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.
No_intervention: Physiotherapy
22 patients receive non-operative treatment for their limp with physiotherapy alone during a 12-month period.
