Summary
This case study highlights a unique bone-patellar tendon-bone anterior cruciate ligament (ACL) reconstruction using an Endobutton. Despite a technical anomaly, the patient achieved successful ligament reconstruction with no laxity one year post-operation.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Anterior cruciate ligament (ACL) reconstruction is a common orthopedic procedure.
- Bone-patellar tendon-bone (BPTB) grafts are frequently used for ACL reconstruction.
- Endobutton fixation is an alternative method for securing grafts during ACL surgery.
Observation:
- A case study involving ACL reconstruction using a BPTB graft and Endobutton fixation is presented.
- The Endobutton did not fully pass outside the femoral cortex, a deviation from standard technique.
- Lachman's test was negative post-operatively, indicating knee stability.
Findings:
- The Endobutton acted as an anchor within the femoral tunnel, leading to a conservative management approach.
- One-year follow-up revealed no graft laxity.
- A second-look arthroscopy confirmed a successful ligament reconstruction.
Implications:
- This case suggests that Endobutton fixation may be successful even with intraoperative technical variations.
- Careful intraoperative technique and post-operative monitoring are crucial for graft success.
- Further studies may explore the long-term outcomes of Endobutton fixation with intraosseous positioning.
