Summary
Arthroscopic lateral release surgery showed good outcomes for knee pain and instability in 60-68.5% of patients. However, results were poor for knee osteoarthrosis.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Arthroscopy
Background:
- Patellofemoral pain and instability are common orthopedic conditions.
- Arthroscopic lateral release is a surgical option for specific knee pathologies.
Purpose of the Study:
- To evaluate the long-term outcomes of arthroscopic lateral release.
- To identify prognostic factors for satisfactory results in different patient groups.
Main Methods:
- Retrospective review of 45 arthroscopic lateral releases.
- Follow-up duration ranged from 2 to 6 years (average 4 years).
- Outcomes assessed for patellar pain, instability, and osteoarthrosis groups.
Main Results:
- Satisfactory results achieved in 60% of the patellar pain group and 68.5% of the instability group.
- Unsatisfactory results were noted in the osteoarthrosis group.
- Postoperative hemarthrosis occurred infrequently (2.2%).
Conclusions:
- Arthroscopic lateral release is a viable option for refractory patellar pain and mild instability after conservative treatment failure.
- Incomplete release and poor patellar tilt are negative prognostic factors for pain.
- Multiple prior dislocations indicate a poorer prognosis for instability.
