Abstract
Although extensor mechanism failure remains a catastrophic complication of knee arthroplasty, there are a number of contemporary techniques with reasonable outcomes that restore function. Chronic failures require advanced reconstruction techniques. Similar complication rates have been reported for the use of autografts, allografts, or mesh reconstructions. Here, we describe our surgical technique in allograft extensor mechanism reconstruction for chronic failures in salvage revision knee arthroplasty using a complete extensor mechanism allograft with a modified proximal fixation and case demonstrations.
期刊介绍：
MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
