Methods 12 patients, diagnosed with chronic lateral epicondylar tendinopathy, will be randomly assigned to receive either open surgical debridement or platelet rich plasma injections. Following treatment, they will be followed up at intervals of 6 weeks and 3, 6 and 12 months. The outcome of each treatment will be assessed using validated outcome scoring measures specifically designed for upper limb pathology. The results of this pilot study will be used to construct a larger randomised control trial.
