Single-stage transcutaneous osseointegrated prosthesis for above-knee amputations including an antibiotic-loaded hydrogel. Preliminary results of a new surgical protocol.

Introduction: Patients with above-knee amputations (AKA) are normally treated with the traditional socket-mounted prosthesis (SMP), which is associated with a high incidence of problems. Osseointegration has been proposed as a promising option for avoiding many common SMP drawbacks. Several concerns have arisen regarding amputee osseointegration, however, mainly with respect to infection.

Posterior hamstring harvest improves aesthetic satisfaction and decreases sensory complications as compared to the classic anterior approach in anterior cruciate ligament reconstruction surgery.

Purpose: The use of the posterior approach for harvesting hamstring grafts has recently become popular thanks to new all-inside techniques and retrograde drills. This study aims to compare the classic anterior approach with the posterior approach in the popliteal fossa.

Methods: Retrospective comparative study of 100 consecutive cases of primary ligamentoplasty performed using ipsilateral semitendinosus autograft with at least one year of follow-up.
