The paper identifies a flaw in the way clinical activity and productivity is assessed at present. This is fundamental to the process on which "payment by results" is based, and therefore must be addressed if trusts are to be financially successful.

The use of biodegradable Transfix femoral fixation technique is a safe and well-accepted method when performing anterior cruciate ligament reconstruction. We report on three cases of deformation and back out of the Bio-Transfix implant over the lateral, distal femoral cortex, with failure of the passing wire when advancing the graft into the femoral tunnel in one of these patients. Two of the patients presented with symptoms of iliotibial band friction syndrome, while the third patient was asymptomatic. The graft had clinically integrated demonstrating AP and rotational stability. The symptoms relieved after removal of the failed Bio-Transfix implants in the symptomatic patients. The aetiology of the implant failure and the alternative methods to avoid such complications are discussed.
