Proximal Hamstring Tears: Endoscopic Hamstring Repair.

Proximal hamstring tears are common among athletes, especially in sports involving eccentric lengthening during forced hip flexion and knee extension, such as hurdles or water skiing. Tears are described by timing (acute [<1 month] or chronic) and severity (partial or complete). Complete tears are easily identified with magnetic resonance imaging; however, partial tears may be subtle and potentially missed.

Editorial Commentary: Biomechanical Analyses of the Hip Capture Are Way Too Simple! The Capsule Is Just One Piece of the Puzzle.

The hip capsule is clearly a significant part of the hip and the considerations that we need to take into account when performing hip arthroscopy. Any study that adds some further clarity to this important structure is welcome and appreciated. The inherent problem with all of these articles is the lack of application to the reality of a living, breathing patient whose capsule changes following time zero of the capsular intervention and also whose negative intra-articular pressure is immediately violated and not recreated following any intervention that is undertaken.

Sonographic evaluation of anterior inferior iliac spine morphology demonstrates excellent accuracy when compared to false profile view.

Purpose: To compare ultrasound examination to false profile radiographs in identification and classification of AIIS morphology. The study hypothesis stated that sonographic imaging of the AIIS correlates well to AIIS morphology seen on false profile radiographs.

Methods: Fifty-three hips in 30 consecutive patients met the inclusion criteria.

Editorial Commentary: It's Not the Age; It's the Story: Acetabular Labral Repair.

The major factor separating a good from a poor outcome in any study is appropriate indications. We don't operate on x-rays, magnetic resonance images, or computed tomography scans alone; we operate on clinical symptoms. With proper patient selection, we can achieve good outcomes from hip arthroscopic surgery in many older patients.

Reliability of the Tönnis Classification and Its Correlation With Magnetic Resonance Imaging and Intraoperative Chondral Damage.

Purpose: To evaluate the reliability of the Tönnis classification in the setting of femoroacetabular impingement (FAI) hips without dysplasia.

Methods: Forty-nine patients with FAI underwent preoperative radiography and magnetic resonance imaging (MRI). Radiographs were evaluated in 2 separate settings by 5 observers and graded according to the Tönnis classification.
