Abstract:

Objective To investigate the early diagnosis and minimally invasive treatment of knee dislocation. Methods Retrospective analysis of 90 cases of traumatic knee dislocation from July 2011 to October 2015 were performed. Arthroscopic reconstruction of the ligament was performed, the joint capsule was not repaired and the popliteal artery was repaired for 3 weeks. If the calf muscles have necrosis, then the tibialis tendon or Achilles tendon was used for ligament reconstruction nerve exploration, release or suture surgery was carried out. Lysholm knee score was adopted for evaluation of the knee function before and after surgery.  Results Of the 90 patients, 78 were followed up for an average of 18 months (9 to 24 months). The Lysholm score for the last follow-up knee function was 78 to 91, with an average of 85.6 points. 75 cases of drawer test and Lachman test was Ⅰ° positive, and all of the internal and external tests were negative; 3 cases of calf muscle underwent necrosis caused by popliteal artery injury: a Ⅱ° relaxation in 1 case, Ⅲ° relaxation in 2 cases. Conclusion Physical and imaging examinations have a positive effect on the diagnosis of traumatic knee dislocation. The one-stage reconstruction of knee ligament injury is feasible, which can lead to a satisfactory short-term curative effect.
