To evaluate the early clinical effects of arthroscopic treatment for cruciate ligament cysts of the knee.
From September 2008 to January 2014, 23 patients with cruciate cysts were treated with arthroscopic surgery. There were 11 males and 17 females, with an average age of 28.3 years old (ranged, 16 to 56 years old). Twenty patients had injuries on the right knee and 8 patients had injuries on the left knee. Eight patients had a history of injury,5 patients had a history of chronic injury,and the other 15 patients had no obvious reasons for the symptom. Before the operation, 24 patients were clearly diagnosed as the cruciate ligament cysts of knee joint,and 4 patients were diagnosed as other problems of the knee, but the diagnosis were corrected after the operation. According to the MRI before the surgery,all the patients could be divided into 3 types: 14 were type I, 6 were type II, 8 were type III. After the operation, the patients were suggested to have a rest for 2 weeks, and take exercises everyday at the same time. The knee range of motion, Lysholm score, International Knee Documentation Committee (IKDC) 2000 subjective score, GLASGOW criteria, and McMurray test, pivot shift test, and anterior drawer test were observed to evaluate clinical results.
All the incisions healed at the first stage without complications. Twenty-five patients were followed up, and the duration ranged from 12 to 52 months, with a mean of 26.7 months. Three patients accepted the reconstruction of ACL or tightened elongated ACL using bipolar radio frequency. The Lysholm score increased from preoperative 59.80 +/- 6.58 to 75.32 +/- 6.49 at the latest follow-up; IKDC 2000 score increased from preoperative 65.36 +/- 6.26 to 81.00 +/- 5.76 at the latest follow-up. According to GLASGOW criteria,23 patients got an excellent result and 2 good.
It has a satisfactory curative effect on ACL reconstruction using bipolar radio frequency. It has advantages of firm fixation, simple and secure operation as well as quick postoperative recovery. It's very important to check the MRI before operations, and carefully seek the cysts during the operations, avoiding the omission of any cysts,especially the cases of multiple cysts. Finally, patients should take exercises actively after operations.
