However, whether to preserve or resect the posterior cruciate ligament (PCL) is still under debate.

In one knee, a PCL preservation technique was performed, and in the contralateral knee, the PCL was resected. The primary outcome was postoperative range of motion (ROM). The secondary outcomes were visual analogue scale (VAS) score for knee pain at walking, Knee Injury and Osteoarthritis Outcome Score for symptoms (KOOS\u2010S) and quality of life (KOOS\u2010QoL), Oxford knee score (OKS), and Forgotten Joint Score (FJS), and measurement of the mechanical femoral\u2010tibial axis (mFTA) on X\u2010ray images.
