Arthroscopic surgery of the hip: current status

Abstract

Arthroscopy of the hip is now recognised as a valuable diagnostic and therapeutic procedure [23]. It is still relatively new and remains largely in the hands of a few specialist centres, but orthopaedic surgeons are increasingly willing to provide it as part of their own service. This article outlines its background and details its clinical and technical application.

Supraacetabular Fossa (Pseudodefect of Acetabular Cartilage): Frequency at MR Arthrography and Comparison of Findings at MR Arthrography and Arthroscopy

“…This is a stellateappearing area deficient of hyaline cartilage located above the acetabular notch. At arthroscopy, the stellate crease may be mistaken for early degenerative change of the cartilage or for an osteochondral defect (7)(8)(9). To our knowledge, the appearance of the stellate crease at MR imaging, CT, or conventional radiography has not been scientifically described in the literature.…”

“…Variants of the acetabular roof, such as the stellate crease, superior acetabular notch, and supraacetabular fossa (SAF), have been described occasionally in the literature as mimickers of acetabular cartilage defects (6)(7)(8)(9)(10)(11)(12).…”

What Factors Influence Long-term Survivorship After Hip Arthroscopy?

“…The anatomic constraints, inelasticity of the periarticular ligaments, proximity of neurovascular structures, and lack of dedicated hip-specific detractors and instruments contributed to the lack of experience in this area. Improvements in arthroscopic optical capabilities and surgical tools, including the introduction of hip-specific distractors in the late 1980s [26], spurred the use of arthroscopic hip surgery. Since then, hip arthroscopy has been used to treat a variety of problems, including labral tears, chondral lesions, loose bodies, and synovitis.…”

The Evolution and Impact of Hip Arthroscopy

“…64 Resection of labral tears remains the most common reason for undergoing a hip arthroscopy. 69 Two thirds of patients have symptomatic improvement after such surgery, 77 although those with associated advanced osteoarthritis do less well 31 (Fig. 2).…”
