Description and mid-term results of the 'over the top' technique for the treatment of the pincer deformity in femoroacetabular impingement.

Pincer impingement is often treated by surgical labral separation from the acetabular rim and rim reduction. A more recent technique the so-called 'over the top' involves reduction of the bony acetabular rim without separation of the labrum. Our purpose is to report mid-term results of the 'over the top' technique.

Internal Snapping Hip Syndrome: Incidence of Multiple-Tendon Existence and Outcome After Endoscopic Transcapsular Release.

Purpose: To report the frequency of presentation of bifid or multiple iliopsoas tendons in patients who underwent endoscopic release for internal snapping hip syndrome (ISHS) and to compare both groups.

Methods: A consecutive series of patients with ISHS were treated with endoscopic transcapsular release of the iliopsoas tendon at the central compartment and prospectively followed up. The inclusion criteria were patients with a diagnosis of ISHS with failure of conservative treatment.

Central compartment release versus lesser trochanter release of the iliopsoas tendon for the treatment of internal snapping hip: a comparative study.

Purpose: To evaluate the results of 2 different techniques of endoscopic iliopsoas tendon release in the treatment of internal snapping hip syndrome.

Methods: Between January 2008 and January 2012, a consecutive series of patients with the diagnosis of internal snapping hip syndrome were treated with endoscopic release of the iliopsoas tendon. The patients were divided into 2 groups according to the surgical technique used.

Clinical outcomes assessment for articular cartilage restoration.

The purpose of this article is to provide an overview and perspective of the available options for clinical outcomes evaluation of articular cartilage repair in the knee. A nonsystematic literature review of reported clinical measures for functional, qualitative, and quantitative structural outcomes evaluation after knee articular cartilage repair was performed. Several outcome scores have been validated for articular cartilage repair in the knee with the International Knee Documentation Committee score, Lysholm score, and Knee injury Osteoarthritis Outcome Score being reported most frequently.
