As a level I trauma hospital, OOU receives an increasing number of knee dislocations. This study evaluates acute knee dislocations seen at OOU from May 1. 1996 through Dec 2004.

Patients and methods: 136 patients with 137 dislocated knees were admitted in the periode. All patients were students or working prior to the injury and all had a high functional level. 50% of the dislocations occured in conjunction with major traffic accidents- the majority of which were motorbikecyklists, while the remaining injuries were sustained during sports. 4 patients had a complete injury of the peroneal nerve on admittance, while an additional 4 had decreased motor strength and \or sensory dysfunction.

In addition one patient had a ruptur of the patellar tendon and one a patella dislocation. Two of the patients in this group had a vascular injury. On admittance the patients underwent a diagnostic exam in the emergency room.. All the patients then had a MRI. The patients were the placed in a brace and on a CPM 2 hours 2 times a day for 7 days, and the vascular status was monitored closely. After 7–10 days the patients underwent surgery including arthroscopic reconstruction of the ACL and PCL with auto or preferably, if available allograft. Results for patient with a followup for more than 6 months are presented including IKDS, Cincinatti, Tegner and a clinical exam with KT1000.

Results:. No serious complication occurred in conjuntion with surgery or the hospital stay. One infection with staf occurred successfully treated. Two patients underwent secondary arthroscopic debridement for arthrofibrosis All the patients have returned to work, but the majority have had to reduce or change their sports activities.

Conclusion:. We have designed a treatment protocol for this difficult patient group. So far the complication frequency has been low.
