Arthroscopic reconstruction of posterior cruciate ligament with quadriceps tendon fixed by a patellar block and an allograft bone plug / 中华创伤骨科杂志

ABSTRACT

Objective To discuss the design of arthroscopic reconstruction of posterior cruciate ligament (PCL) with quadriceps tendon fixed by a patellar block and an allograft bone plug, and its clinical outcome. Methods Thirteen patients suffering from PCL injury were treated by the technique mentioned above. The connection between quadriceps tendon and superior patellar pole was preserved in the harvest process of quadriceps tendon. The femoral tunnel was made like a bottle neck, which was clogged with the patellar bone block. The quadriceps tendon strip was fixed by an allograft bone plug pressed into the tibial tunnel. Their functional recovery was evaluated by Lysholm scoring and IKDC(International Knee Documentation Committee) criteria. Results In the average follow-up period of 19 months, there were not any severe nerve or blood vessel lesions, or failures of transplanted ligament None of the patient complained of knee instability after the operation. The pain was relieved in most patients, but three complained of pain after knee movement A little calcification was found in the quadriceps tendon at the superior patellar pole one year after the operation in the X-ray of a patient There was significant difference in Lysholm scale between pre-operation and post-operation (P
