Chronic Patellar Tendon Rupture: Choice Between Two Allograft Reconstruction Techniques: A Case Report

Area of Science:

• Orthopedic surgery
• Musculoskeletal reconstruction
• Sports medicine

Background:

• Neglected patellar tendon ruptures present unique surgical challenges.
• Allograft reconstruction is a viable option for complex tendon defects.

Purpose of the Study:

• To report outcomes of two distinct allograft techniques for neglected patellar tendon rupture.
• To compare the functional results of Achilles tendon allograft versus bone-patellar tendon allograft.

Main Methods:

• Case 1: Reconstruction using an Achilles tendon allograft.
• Case 2: Reconstruction using a bone-patellar tendon allograft.
• Both cases involved early range of motion protocols and functional assessment at 1-year follow-up.

Main Results:

• Both surgical techniques facilitated early range of motion.
• Good functional outcomes were achieved in both patients at the 1-year follow-up.
• No major complications were reported in either case.

Conclusions:

• The selection of allograft type is crucial for successful patellar tendon reconstruction.
• Achilles tendon allografts offer high tensile strength and availability.
• Bone-patellar tendon allografts may be preferred for cases with bone loss requiring enhanced biological incorporation.
