Summary

INTRODUCTION:
Injuries of the posterolateral corner of the knee can cause severe disability due to instability. The popliteus muscle-tendonligament complex, lateral collateral ligament, and posterolateral capsular structures are a complex combination of both dynamic and static stabilizers. There have been many reports on procedures performed to stabilize the posterolateral knee. Crutial is an anatomical reconstruction of this stabilizers. Restoration of only a portion of the posterolateral structures may result in residual instability.

MATERIAL AND METHODS:
Since 2008 to 2009 we treated 6 patients with lateral knee instability. There were 5 men and 1 women, with average age 50 (range, 25 to 67). The minimum follow-up period was one year.

RESULTS:
There was no serious complication, all patients are relatively satisfied. Two patients show partial lateral laxity being treated by orthosis, further surgical procedures were refused. The peroneal nerve function did not regenerate in one case, other patient showed only partial reinervation, function recovered fully for the third patient with neural palsy. Anatomical reconstruction with semitendinosus tendon together with proximal tibial opening wedge osteotomy was performed for next patient. Rotating hinge endoprosthesis was the ultimate solution for obese patient with arthrosis.

DISCUSSION:
Anatomical reconstructions require recovery of the three most important structures of the posterolateral complex – lateral collateral ligament, popliteus muscle and popliteofibular ligament.

CONCLUSIONS:
Posterolateral corner damage is often of a different extent and only few knees suffer one isolated injury. It is therefore difficult to assemble a consistent group of patients for comparativeness.

KEY WORDS:
posterolateral corner, lateral knee laxity, surgical techniques, reconstruction.
