Purpose
Describe the arthroscopic surgical technique for decompressing central acetabular impingement by removing notch osteophytes (notchplasty) and its potential role in slowing arthritis progression.
Methods
Technical note and procedural video demonstrating arthroscopic notchplasty; clinical observations relating notch osteophytes to cartilage and ligamentum teres damage.
Key Findings
- Notch osteophytes are common in hip arthroscopy cases.
- Removing them can relieve mechanical impingement and reduce cartilage damage.
- The procedure may delay arthritis progression by decompressing the acetabular notch.
Conclusion
Arthroscopic acetabular notchplasty is a safe and effective technique addressing structural causes of central impingement.
What Does This Mean for Providers?
- Consider notchplasty when notch osteophytes contribute to symptoms or joint mechanics abnormalities.
- Early intervention may help preserve cartilage and delay arthritis in select patients.
- Familiarity with the technique can expand arthroscopic treatment options for central impingement.
