Abstract

Revolutionizing post-TKR care, novel use of Achilles tendon allografts emerge as a game-changer for displaced extensor mechanism, tackling one of the most challenging complications of total knee replacement. By restoring active knee extension and preventing lateral patellar subluxation, this technique empowers patients with improved mobility and independence.
The study included three patients with persistent patellar instability and malalignment were treated with a lateral retinacular release and Achilles tendon allograft fixation around the quadriceps mechanism. At 12 months, functional outcomes improved significantly: the Kujala score increased from 50 to 85, Knee Society Score (KSS) from 60 to 90, and Tegner Activity Level from 2 to 6. Postoperative imaging confirmed successful graft incorporation and alignment correction.
This technique, combining soft-tissue release with robust Achilles tendon allograft reconstruction, offers a promising solution for complex post-TKR patellar maltracking, highlighting the strength and adaptability of the Achilles tendon in restoring knee dynamics.
Overcoming the limitations of autografts and other traditional methods, this novel approach offers unmatched strength and adaptability while addressing critical surgical complexities. Despite potential challenges like stiffness and availability, the outcomes highlight enhanced function, stability, and patient satisfaction. With its innovative approach and tailored rehabilitation protocols, this procedure sets a new benchmark in orthopedic reconstructive surgery, combining precision and patient-centric care to redefine recovery.
