Abstract

PURPOSE:

This study evaluated the treatment outcome of posterior cruciate ligament (PCL) reconstruction using the Medical Outcome Study 36-item Short-Form Health Survey (SF-36), a patient-based quality of life (QOL) questionnaire comparing it with anterior cruciate ligament (ACL) reconstruction.

METHODS:

Patients who underwent reconstruction at our center for PCL (n = 24) or ACL (n = 197) injury were studied. The patients were evaluated using SF-36, visual analogue scale (VAS) for knee pain, Lysholm scale, posterior or anterior tibial translation and range of motion (ROM) before surgery until 24 months after surgery. Results were compared.

RESULTS:

In the ACL group, all evaluation methods showed significant improvement after surgery. In the PCL group, however, improvement was observed in only three of eight subscales of the SF-36, Lysholm score and posterior tibial translation after surgery. In intergroup comparison, the PCL group showed inferior performance in three subscales of the SF-36, Lysholm score and ROM for flexion compared with the ACL group.

CONCLUSIONS:

The surgical outcome of PCL reconstruction was inferior to that of ACL reconstruction both in patient-based and conventional doctor-based assessments. An improved surgical technique for PCL is required.
