The â…  Stage Therapy Prognosis Of Traumatic Knee Dislocation

Objective:To explore the clinical outcomes of the treatment of traumatic knee dislocation by anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) combined reconstruction under arthroscopy and repair/reconstruction of the injured LCL and MCL in one stage and functional exercise in early post-operation stage.Methods:From June 2008 to October 2009,there were 10 patients with knee dislocation (8 males and 2 females), with the average age of 42 years (ranging from 35 years to 55 years), whose ACL and PCL were reconstructed under arthroscopy and whose collateral ligaments of the knee were repaired or reconstructed [3 with injuries of ACL, PCL, medial collateral ligament (MCL) and lateral collateral ligament (LCL);7 with injuries of ACL, PCL and MCL]. None case with common peroneal nerve injury,neither vascular injury; 6 with lateral meniscus injury and 4 with medial meniscus injury. They came to our hospital within from 5h to 3months after injuries. Every patient had single knee dislocation. The outcomes were measured from the following aspects:range of the knee movement, clinical improvement and Lysholm scoring. Results:The ten patients were followed up for 6 months to 18 months, with the average time of 11.1 months. Nine patients recovered to the level that they could walk and work by themselves, PE:Lachman test, anterior drawer test and posterior drawer test were negative, The side-to-side difference was less than 5 mm. But there was 1 patient who felt painful from the knee and unstable. PE:Posterior drawer test was positive,about 10mm,but Lachman test and anterior drawer test were negative. The side-to-side difference was less than 5 mm. Lysholm scale of the knee function was 19.3±5.3 preoperatively and 75.2±10.5 postoperatively (P< 0.05). The movement ranges of the knee were (95.5±5.5)°preoperatively and (125.0±9.2)°postoperatively (P<0.05).Conclusion:One-stage Combined Reconstructing the ACL and PCL and Repairing or reconstructing MCL and LCL and functional exercise in early post-operation stage is an effective method to treat traumatic knee dislocation.
