External rotation strength deficit after hip resurfacing surgery.

2008

The aim was to assess the effect of resurfacing hip arthroplasty on hip muscle function, when, in the posterior approach, the piriformis tendon and outer rotators of the hip joint were divided. The unoperated side was used as a control.Thirty-three consecutive patients (mean age 55 years, 73% males) were operated using the posterior approach. Main outcome measures were isometric muscle strength of external and internal rotators and extensors of the hip and hip pain.Hip external rotation strength (p0.001) and leg extension strength (p0.001) were significantly lower on the operated side compared with the un-operated side prior to the surgery. On the operated side external rotation strength de…
