Abstract :

Tendinopathy due to sport injury or over use is one of the most common clinical disorder in musculoskeletal clinics. Th e chronic degenerative condition frequently does not respond to treatment. In the current study, we propose that autologous tendon progenitor cell therapy (ATT) is eff ective in preventing tendon degeneration. We have conducted pre-clinical evaluation using a collagenase induced rabbit Achilles tendinopathy model. On the basis of the evaluation and characterisation of tendon cells, we have conducted a phase I trial in patient with refractory lateral epicondylitis.. For pre-clinical study, chronic tendinopathy in rabbit was created in the left Achilles tendon. Th e result showed that ATT improved tendon remodeling, histological outcomes, collagen content and tensile strength of tendinopathic Achilles tendons. Injected tenocytes were integrated into tendon tissue and could be tracked up to 8 weeks in vivo . As the pre-clincial study showed ATT may be a useful treatment of chronic Achilles tendinopathy, we next evaluated the safety and level of effi cacy of ATT for treatment of refractory lateral epicondylitis in a pilot study. Cultivated autologous tenocyte from the patellar tendon were injected into the sites of intrasubstance tears and fi brillar discontinuity of the common extensor origin under ultrasound guidance. Th e interim results demonstrated sixteen patients who reached the 6 month period have shown up to 60% improvement in all scores when compared to pre-treatment. MRI results showed infi ll of tendon tear in the majority of patients but there was some variation in the quality of regenerated tendon. In conclusions, our study indicates that the feasibility of ATT for the treatment of tendinopathy
