Patellar tendon rupture repair using Dall-Miles cable

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Patellar tendon ruptures require surgical repair to restore knee function.
• Traditional repair methods may involve prolonged immobilization, delaying rehabilitation.
• Minimally invasive techniques are sought to improve patient outcomes and recovery times.

Purpose of the Study:

• To evaluate the efficacy of end-to-end patellar tendon repair reinforced with a Dall-Miles cable.
• To assess the impact of this technique on early range of motion and quadriceps strength.
• To determine the safety and effectiveness of immediate weight-bearing and early mobilization protocols.

Main Methods:

• Ten patients underwent patellar tendon repair using an end-to-end suture technique with retinacular repair.
• A Dall-Miles cable was used for reinforcement, passed through the patella and tibial tubercle.
• The cable was tensioned at 60 degrees of flexion to allow immediate motion up to 100 degrees.

Main Results:

• Full extension was achieved by 1 week postoperatively.
• Average knee flexion reached 138 degrees at 6 months, comparable to the noninvolved knee.
• Mean quadriceps strength at 1 year was 72% of the contralateral leg, with no patella infera or reruptures.

Conclusions:

• End-to-end patellar tendon repair with Dall-Miles cable reinforcement facilitates immediate rehabilitation.
• This technique allows early restoration of range of motion and adequate quadriceps strength.
• The method provides a safe and effective alternative to prolonged immobilization for patellar tendon ruptures.
