Treatment of chronic patellar ligament lesion with autograft and v-y quadricepsplasty.

Objective: Review of the literature concerning the subject and to compare the results of the technique we have been using with the ones reported on the literature.

Methods: This is a retrospective, cross-sectional and observational study. We evaluated the records of patients treated surgically at the Hospital from Hospital Maria Amelia Lins January 1997 to January 2011.The following variables were considered: age, gender, side, degree of injury, mechanism of trauma, associated injuries, time elapsed between injury and surgical procedure, complications, range of motion and muscle strength.

Results: Five patients underwent surgical treatment with the use of autograft semitendinosus and gracilis tendons and V-Y quadricepsplasty. Regarding gender, there was a male predominance (80%). The average age was 35.2 years old. The right side was the most affected (60%). The predominant mechanism of injury was motorcycle accident (80%). All patients had a complete tendon lesion. Time between injury and surgery averaged 10.4 months. Four patients (80%) had had associated injuries. In all patients muscle strength was satisfactory (M4/M5). Wound dehiscence was observed in 01 patient. Average postoperative range of motion was 110°.

Conclusions: These are rare lesions. Stretching the quadriceps is essential to decrease the tension to the reconstructed patellar ligament and patellofemoral joint. Use of a quadriceps transtendon tunnel is an option to prevent fractures. Hypotrophy of the quadriceps is inevitable, however, the resulting force is sufficient for daily living activities.
