Abstract
The debate about retaining or sacrificing the posterior cruciate ligament (PCL) in total knee arthroplasty continues. Benefits of PCL retention cited by researchers include increased flexion, improved posterior rollback, improved quadriceps function, decreased post-tibial subluxation and reduced interface stress. On the other hand, other researchers contend that sacrificing the PCL affords latitude for correction of fixed deformity, improves exposure, ligament balancing, flexion and stability.
This paper reports on a bilateral knee study that is currently in progress and involves three separate sites/investigators. It describes Knee Society scores, range of motion and intra-operative metrics for 100 patients followed up for one to four years.
