Abstract

Purpose: Schenck IV knee dislocation patients have dissatisfactory knee function and return-to-sport rate with the existing treatment methods. The purpose of this study was to illustrate a one-stage arthroscopic multiple ligament reconstruction method for treating Schenck IV knee dislocations.

Methods: A retrospective case series study was performed. All patients with a history of Schenck IV knee dislocation who underwent one-stage arthroscopic multi-ligament reconstruction from 2010 to 2018 were followed for 24 months. The outcomes, including general patient data, Lysholm scores, International Knee Documentation Committee (IKDC) scores, visual analog scale (VAS) pain scores, knee active range of motion, and complications, were reviewed. The data was analyzed with paired-samples t-test.

Results: A total of 12 patients, comprising nine males and three females, were followed up and reviewed. The mean age at the time of the surgical procedure was 40.3 ± 9.0 (22-57) years. The mean body mass index (BMI) was 24.6 ± 4.9 (15.2-32.5) kg/m2 . The mean IKDC score and Lysholm score before surgery were 30.4 ± 6.1 (21-42) and 28.2 ± 6.2 (22-39), respectively. The average operation time was 121.8 minutes. The mean IKDC score and Lysholm score at the 24-month follow-up were 80.6 ± 6.5 (68-92) and 82.0 ± 7.5 (72-95), respectively. There were significant differences in the IKDC and Lysholm scores between the preoperative and 24-month postoperative time points (p < 0.01). The mean knee range of motion was 124.6° ± 6.6° (115°-135°) at the 24-month follow-up. No major complications occurred.

Conclusions: The results of this retrospective study suggest that the new arthroscopic one-stage multi-ligament reconstruction technique is an effective way to treat Schenck IV knee dislocation with satisfactory postoperative knee function.

Illustration of the reconstruction model. Figure shows the bone tunnels of the new multiligament reconstruction technique. The three‐dimensional knee model was constructed by MIMICS (Materialize's interactive medical image control system) using data from the CT scan of a healthy volunteer. The bone tunnels were built with MIMICS according to the methods used in the surgical procedure. (A, B) Shows the frontal and lateral views of the reconstructed model.
