Relative (%) change in computed dislocation-resistance energy developed during hip flexion for simulated capsule acetabular insertion detachments (circle symbols) and femoral detachments (square symbols) as a function of circumferential position of detachment site. Construct stability compromise depended on both the site and extent of the detachment. Otherwise comparable-extent defects generally involved greater stability compromise for femoral attachment defects located on the medial aspect and for acetabular attachment defects located on the lateral aspect. Construct stability was consistently returned appreciably toward intact levels for suture repair (demonstrated by piecewise curves) of the most compromising detachments (posterolaterally located).
