Retrospective cohort study comparing postoperative joint stability between all-inside PCL reconstruction technique and conventional PCL reconstruction technique in patients with multiligament knee injury.

Objectives: The purpose of our study was to compare (1) posterior cruciate ligament (PCL) laxity, (2) patient-reported outcome, and (3) complications after the all-inside PCL reconstruction (Al-PCLR) technique and conventional PCLR (CON-PCLR) technique at minimum 2-year follow-up. We hypothesized that AI-PCLR and CONV-PCLR would yield similar results in PCL laxity, patient-reported outcomes, and complications.

Method: A retrospective cohort study was conducted on patients who underwent PCLR with the Al-PCLR technique and CON-PCLR technique from 2012 to 2023 in a single hospital.
