Lateral epicondylitis, or ’tennis elbow’, is a common condition that usually affects patients between 35 and 55 years of age. It is generally self-limiting, but in some patients it may continue to cause persistent symptoms, which can be refractory to treatment. This review discusses the mechanism of disease, symptoms and signs, investigations, current management protocols and potential new treatments.

Introduction

Massive rotator cuff repairs have up to 60% failure rate and repair of a chronic repair can have up to 40% failure rate. With this in mind, new methodologies are being to being developed to overcome this problem. The use of tendon augmentation grafts is one of them. Prior attempts have shown equivocal or poorer outcomes to control repairs. Aims and objectives: The specific aim of these expereiments was to test how well ovine tendon cells would take to a specific biological augmentation graft (Ligamimetic), and wheter tissue engineering techniques would enhance this.

Introduction

Rotator cuff tears remain a problem, with massive tears having a failure rate of repair reported of up to 60%, despite advances in surgical techniques. Tissue engineering techniques offers the possibility of regenerating damaged tendon tissue to a pre-injury state. We explore these techniques by implanting two novel tendon augmentation grafts with use of platelet rich plasma (PRP) in sheep.
