A woman in her late 70s with bilateral total hip arthroplasty (THA) presented with left hip pain arising immediately after the last THA procedure, progressively worsening. Clinically, a severe abductor insufficiency with Trendelenburg limp was observed. Moreover, symptomatic leg length discrepancy required a contralateral heel lift of 0.5 cm. She was previously managed conservatively without any clinical benefit. Radiographs showed a well-fixed uncemented straight, sitting proud stem. MRI showed a large abductor tear. A minimally invasive proximal advancement of the greater trochanter was planned to allow direct surgical repair of the abductor lesion. The patient made a good recovery, and 12 months after surgery, wire removal was performed. The patient gained significant improvements in hip function (Harris Hip Score from 52 to 89), full limp recovery and complete pain relief at 13 months follow-up from primary surgery.
