Background:
Rupture of the posterior cruciate ligament (PCL) is a rare knee
injury in childen with open growth plates. So far only case studies have been
reported in the literature. We present follow-up results of six patients with open
physes treated with PCL reconstruction.
Purpose / Aim of Study:
To evaluate clinical outcome after PCL reconstruc-
tion in six skeletal immature patients.
Materials and Methods:
Between August 2006 and October 2010 six skel-
etal immature patients (one girl and five boys) were treated with PCL recon-
struction. In 5 cases hamstring tendons autografts were used. One patient was
reconstructed with use of a tibialis anterior tendon allograft. At time of surgery
median age was 9 years (range 6 – 14). Median follow-up time after surgery
was 50 months (range 41 – 90). Outcome was evaluated by KOOS and Tegner
scores, Instrumented knee laxity and radiologic long axis leg length measure-
ments.
Findings / Results:
Median KOOS score at follow up regarding symptoms, pain,
ADL, Sport, and QOL were 79 (range 43 – 100), 89 (range 41 – 100), 99
(range 66 – 100), 70 (range 5 – 100), and 81 (range 19 – 94) respectively.
Median Tegner score was 6 (range 4 – 7). Median side to side difference in lax-
ity using KT1000 was 2 mm (range 1 – 5) at 25 degrees of flexion and 3 mm
(range 3 – 6) at 70 degrees of flexion. No side to side difference in knee exten-
sion was found. In contrast a median difference of 8 degrees of flexion decrease
was found . All but one patient had returned to sports at follow-up. One patient
had a leg length discrepancy of 16 mm, the index knee being the longer.
Conclusions:
PCL reconstruction resulted in fair to good clinical outcome in
skeletal immature children.
