The average duration till operation was 6 months from injure. After operation, the patients started functional rehabilitation with protection of unlimited knee orthosis for 12 weeks. Results Twenty cases were follow-up for 4 to 22 months with average of 6 months. Lysholm score from 35.9 preoperation increased to 88.5 postoperation. Most patients had significant improvement in stability and function of knee join(excellent in 12,good in 4 and fair in 2). Conclusion Bipolar radio frequency could be applied to tighten elongated cruciate ligament of continuous structure and avoid potential revision and reconstruction in some cases.
