Polyethylene terephthalate prosthesis as a gastrocnemius tendon implant
- Features of the implant?
- What was the mechanism of failure in the constructs tested?
Morton, Vet Surg, 2015:
- The implant is biocompatible, encourages anatomic ingrowth, and is enclosed within the paratendon so that tendon gliding is not compromised
- The implant itself failed before distal fixation failure in 67% of the constructs
