Single-Bundle PCL Reconstruction with Remnant Preservation: Midterm Follow-up

Research output: Contribution to journalArticlepeer-review


Background. Remnant preservation was developed as a routine procedure for posterior cruciate ligament (PCL) reconstruction, but it is not easy. Objectives. Our study aimed to evaluate the outcomes of a minimum 5-years follow-up of remnant preservation PCL reconstruction. Methods. The study was a prospective cohort analysis of 44 patients who underwent PCL reconstruction with remnant preservation and a minimum 5-years follow-up. Outcome parameters included were modified Cincinnati score, Lysholm knee score, International Knee Documentation Committee (IKDC) subjective score, degree of laxity (Posterior Drawer Test), single-leg hop test, and knee x-ray findings. Results. The mean diameter of the hamstring autograft was 8 ± 2.04 mm. The mean of Lysholm knee scores increased from 65.15 ± 10.48 to 86.94 ± 4.80. The IKDC subjective score increased from 62.55 ± 18.10 (range, 40–65) to 88.65 ± 3.44 (range, 65–100) points, and the Modified Cincinnati Score from 63.32 ± 13.65 to 86.24 ± 1.64. For Posterior Drawer Test results after surgery, 37 patients (84%) had grade 1, 5 (11%) had grade 2, and 2 (4.5%) had grade 3 of laxity. For the range of motion measurements, 39 (88.6%) patients had normal knee status, 3 (6.8%) presented with flexion deficit >25o, and 1 (2.2%) had a 16o-25o deficit in flexion, and 1 (2.2%) had a 16o-25o deficit in extension. Eight cases had the infection at the local incision site, which was resolved with conservative treatment. Conclusion.
