Modified Pulvertaft on Weave Technique Restores Full Active Knee Extension in Patients With Large Chronic Quadriceps Tendon Rupture: A Case Series.

Purpose: We aimed to investigate the clinical and functional outcomes, including maximal and explosive strength, after chronic quadriceps tendon rupture repair with Modified Pulvertaft on Weave (MPW) technique METHODS: Knee joint range of motion (ROM), patella height, thigh circumference, and Lysholm and International Knee Documentation Committee (IKDC) scores were assessed preoperatively and postoperatively. The knee extensors maximal (isokinetic peak torque and isometric maximal voluntary contraction (MVC) torque) and explosive strength-rate of torque development (RTD) early [RTD and RTD] and late [RTD]-were performed. We assessed the thigh circumference and vastus lateralis muscle thickness (MT) as indicators of quadriceps muscle mass, and the voluntary quadriceps activation using surface electromyography (EMG).

Surgical Treatment for Chronic Rupture of the Patellar Tendon Performed in 2 Stages.

Patellar tendon rupture is an uncommon but disabling lesion. It usually occurs in men younger than 40 years, through direct or indirect trauma. Obtaining satisfactory results with treatment of chronic injuries and re-ruptures in which the patella retracts owing to quadriceps contraction is a challenge.
