Management of insufficiency of posterior cruciate ligaments.
BACKGROUND
This study aims to evaluate the role of different methods in management of insufficiency of posterior cruciate ligament (PCL) that were used in VGH-Taipei.


METHODS
129 cases with insufficiency of PCL were collected to evaluate, according to functional and dynamic criteria, the results of different managements which were graded as good, fair, or poor. The patients were divided into 3 groups, i.e. group 1 with conservative rehabilitation therapy, group II with surgical reattachment, and group III with surgical ligament reconstruction that had 3 subgroups including IIIa reconstruction with medial head of gastrocnemius, IIIb with patellar tendon and IIIc with artificial ligament. The artificial ligaments used were Leeds-Keio ligament (group IIIcl), Dacron ligament (group IIIc2) and Goretex ligament (group IIIc3). The duration from injury to treatment varied from 3 days to 12 years with mean 45 weeks. The followup period was from 38 months to 112 months with mean 62 months.


RESULTS
The results revealed 6 cases of good grade (25%) and 18 cases of fair grade (75%) in group 1, 20 cases of good grade (95%) and 1 case of fair grade (5%) in group II, 14 cases of good grade (40%), 10 cases of fair grade (29%) and 11 cases of poor grade (31%) in group IIIa, 3 cases of good grade (100%) in group IIIb, 13 cases of good grade (82%) and 3 cases of fair grade (18%) in group IIIcl, 19 cases of good grade (83%), 3 cases of fair grade (12%) and 1 case of poor grade (4%) in group IIIc2, and 3 cases of good grade (43%), 3 cases of fair grade (43%), and 1 case of poor grade (14%) in group IIIc3.


CONCLUSIONS
Conservative intervention could be satisfactory in some cases with PCL insufficiency, especially in cases with isolated PCL injury, while surgical methods is mandatory in the others, especially in cases with chronic symptomatic PCL insufficiency.
