A 32 year-old-female recreational rower presents two months after recent surgery with continued right hip pain. She was diagnosed with femoroacetabular impingement (FAI) and underwent right-sided hip arthroscopy with femoroplasty, acetabuloplasty, and labral repair using a peri-portal capsulotomy technique without capsular closure. Her current post-operative radiographs and MRI are shown in Figures A-D, with notable radiographic measurements including an alpha angle of 47°, and her dictated operative report notes overall Outerbridge Grade I cartilage changes with focal areas of Grade 2 involvement. Which of the following is the most likely reason for her continued pain post-operatively?

A 35-year-old patient with persistent right groin pain returns to clinic for re-evaluation. His pain is reproduced with hip flexion, and internal rotation is limited to 10 degrees. A representative radiograph is shown in Figure A. Having exhausted conservative treatment, he is indicated for arthroscopic management. Which of the following characteristic wear patterns would you most expect to encounter intra-operatively?

A 76-year-old veteran presents to your clinic with right groin pain. He reports that he has significant pain with activities like bending down to tie his shoes, rising from a low seat, and walking up and down stairs. On physical examination, he has decreased hip range of motion. Of note, the patient’s past surgical history is notable for a posterolateral decompression and fusion from L4-S1 for degenerative spondylolisthesis. Radiographs demonstrate advanced right hip osteoarthritis. After an appropriate trial of non-operative treatment, the patient elects to undergo total hip arthroplasty. Which description accurately describes the altered biomechanics in this patient that place them at increased risk for dislocation?

Question

Recon
- Hip-Spine Syndrome

Figure 50 shows the cross table lateral radiograph of a 31-year-old paratrooper who has recalcitrant groin pain. The pain is worse after activities such as standing or sitting (driving). Examination reveals that pain can be reproduced by internal rotation of the leg with the hip and knee in 90 degrees of flexion. Extensive nonsurgical management has failed to provide relief. What is the treatment of choice?
