Abstract
The TruFit® CB (cartilage/bone) (Smith & Nephew, San Antonio, TX) is a resorbable implant consisting of semiporous 75:25 poly d,l-lactide-co-glycolide (PLG) copolymer, calcium sulfate, polyglycolide acid (PGA) fibers, and surfactant [1]. The implant is designed to replicate mechanical properties of the superficial (articular cartilage) and deep (bone) aspects of an osteochondral lesion. The superficial phase is softer and functions as a scaffold to facilitate cartilage regeneration. The deep phase contains calcium sulfate, which improves its strength. Incorporation of the PGA fibers has been shown to improve the implant's compressive modulus and yield strength [2].
