Summary
This study introduces a new arthroscopic surgery for Schenck IV knee dislocations, improving patient knee function. The one-stage technique shows effective outcomes for multiple ligament reconstruction.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Schenck IV knee dislocations present significant challenges in achieving satisfactory knee function and return-to-sport rates with current treatments.
- Existing methods often lead to suboptimal outcomes for patients with complex knee instability.
Purpose of the Study:
- To evaluate a novel one-stage arthroscopic multiple ligament reconstruction technique for treating Schenck IV knee dislocations.
- To assess the efficacy and safety of this minimally invasive approach.
Main Methods:
- A retrospective case series involving 12 patients with Schenck IV knee dislocations who underwent one-stage arthroscopic multi-ligament reconstruction between 2010 and 2018.
- Patients were followed for 24 months, with outcomes including Lysholm scores, International Knee Documentation Committee (IKDC) scores, visual analog scale (VAS) pain scores, and knee range of motion assessed.
- Data analysis utilized paired-samples t-tests to compare pre- and post-operative scores.
Main Results:
- Significant improvements were observed in both IKDC (30.4 to 80.6) and Lysholm (28.2 to 82.0) scores at 24-month follow-up (p < 0.01).
- Mean knee active range of motion reached 124.6° postoperatively.
- No major complications were reported during the follow-up period.
Conclusions:
- The arthroscopic one-stage multiple ligament reconstruction technique effectively treats Schenck IV knee dislocations.
- This approach yields satisfactory postoperative knee function and suggests a promising alternative for managing complex knee injuries.
