PURPOSE: To evaluate the clinical outcomes for arthroscopic treatment of acute posterior cruciate ligament (PCL) avulsion fractures with adjustable-loop cortical button fixation device. METHODS: Patients with PCL tibial avulsion fractures treated with an adjustable-loop cortical button fixation device between October 2019 and October 2020 were retrospectively identified. Patients with type 1 were treated using plaster fixation as a conservative treatment, whereas patients with type 2 and 3 with displacement were treated using an arthroscopic adjustable-loop cortical button. Operating time, incision recovery, complications, and postoperative fracture healing time were monitored. All patient follow-up was done at 12 months’ postoperatively. Lysholm Knee Score and the International Knee Documentation Committee score were used to assess knee function. RESULTS: A total of 30 patients were included in the study (20 male/10 female; mean age 45.5 years, range 35-68 years). The mean operative time was 67.5 minutes (range: 50-90 minutes). The postoperative incision healed at stage A without complications, such as medically induced vascular nerve injury, intra-articular hematoma, or infection. All 30 patients were tracked postoperatively for 12 to 14 months, with a mean follow-up period of 12.6 months. The Lysholm knee function score was 45.93 ± 6.15 before surgery and 87.10 ± 3.71 at 12 months after surgery, and the International Knee Documentation Committee score was 19.27 ± 4.40 before surgery and 95.47 ± 1.87 at 12 months after surgery, with a statistically significant difference. CONCLUSIONS: The treatment of PCL avulsion fractures with arthroscopic adjustable-loop cortical button fixation is easy to perform and shows good clinical results in our study. LEVEL OF EVIDENCE: IV, therapeutic case series. |
