Summary
Reconstructing the lateral collateral ligament (LCL) with a semitendinosus graft during ACL or PCL surgery shows promising outcomes. Most patients experienced symptom relief and returned to their previous activity levels.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Ligament Reconstruction
Background:
- The lateral collateral ligament (LCL) is crucial for knee stability.
- Combined ACL and PCL injuries often involve LCL insufficiency.
- Reconstruction of the LCL is essential for restoring knee function.
Purpose of the Study:
- To evaluate the efficacy of semitendinosus tendon graft reconstruction for the LCL.
- To assess outcomes when LCL reconstruction is performed concurrently with ACL or PCL reconstruction.
- To determine the functional recovery and stability after combined ligamentous knee reconstruction.
Main Methods:
- Retrospective analysis of 13 patients undergoing LCL reconstruction with semitendinosus grafts.
- Concurrent reconstruction with ACL (n=6) or PCL (n=7).
- Assessment using IKDC form, radiographic stress views (lateral joint opening, posterior tibial translation), and clinical examination.
Main Results:
- Most patients reported minimal to no pain post-surgery.
- Radiographic assessment showed minimal lateral joint opening (0-5 mm) in most cases.
- 11 out of 13 patients returned to their pre-injury activity level, with two returning to one level lower.
Conclusions:
- Free semitendinosus tendon grafts are effective for LCL reconstruction.
- Concurrent LCL reconstruction with ACL or PCL surgery leads to favorable functional outcomes.
- This technique restores knee stability and allows return to high activity levels.
