Summary
A novel "coiling-up procedure" enables extra-articular arthroscopy using a coil lifter for joint access. This technique, demonstrated for vastus lateralis release, expands arthroscopic applications.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Extra-articular arthroscopy is limited in creating a working space.
- Direct visualization of structures outside the joint capsule is challenging.
Purpose of the Study:
- To introduce and describe the novel "coiling-up procedure" for extra-articular arthroscopy.
- To demonstrate its application in vastus lateralis release for painful bipartite patella.
Main Methods:
- A coil-shaped lifter is utilized to establish an extra-articular working space.
- Dry arthroscopy is performed within this created space.
- The technique can be integrated with conventional intra-articular arthroscopy.
Main Results:
- Successful application of the coiling-up procedure for vastus lateralis release in patients with painful bipartite patella.
- Achieved direct visualization from both intra-articular and extra-articular perspectives.
Conclusions:
- The coiling-up procedure is an innovative technique for extra-articular arthroscopy.
- This method holds potential for broader applications in various anatomical regions.
