Diagnosis and Treatment of Musculotendinous Deficiencies of the Hip.

Abstract

Musculotendinous deficiencies related to iliopsoas tendinitis and abductor mechanism disruption following total hip arthroplasty (THA) are frequently under diagnosed and can be frustrating to surgeons and devastating to patients with painful THAs with normal appearing radiographs. Current peer-reviewed evidence is presented for diagnosis and treatment options for these two musculotendinous deficiencies. While these musculotendinous deficiencies are treatable, prevention during the primary THA is ideal, and special attention should be taken into consideration for optimized acetabular cup size and position, optimized hip biomechanics, and preservation and protection of the abductor tendon insertion to the greater trochanter.
