Brief summary

Lateral epicondylitis (LE) or "tennis elbow" is the most commonly diagnosed condition of the elbow and occurs mostly in patients whose activities require strong gripping or repetitive movements. 1 in 10 patients with LE who receive standard therapies like coricosteriod injections do not obtain relief from symptoms. In Australia, such patients with severe, chronic non responsive LE for over 6 months are referred for surgical treatment. OrthoATI (Trademark) is a class 3 biological autologous tenocyte implantation (ATI) product manufactured in Australia by Orthocell Ltd, that could potentially prevent or delay the need for surgery in LE patients who don't respond to standard therapies. OrthoATI (Trademark) is indicated for patients with symptoms of degenerative tendon injury who have failed conservative treatment methods. The current research project is a 1 year, single dose, single-centre, randomised, open label, parallel group, comparator controlled, non-inferiority study to assess the efficacy, safety and tolerability of OrthoATI (Trademark) in patients with severe, chronic, treatment resistant lateral epicondylitis compared to surgery.

Interventions

Ortho-ATI (Trademark) is a Class 3 Biological autologous tenocyte implantation (ATI) product manufactured in Australia by Orthocell since 2008. Ortho-ATI (Trademark) is intended for homologous and autologous use only. The product comprises autologous tendon cells taken from healthy patellar tendons of patients. These autologous cells are proliferated using an in vitro cell culture technique and reconstituted with patient’s own serum for local injection. Patellar Tendon Biopsy Autologous tenocy

These autologous cells are proliferated using an in vitro cell culture technique and reconstituted with patient’s own serum for local injection. Patellar Tendon Biopsy Autologous tenocytes will be harvested from participants via patellar tendon biopsy under local anaesthetic by an orthopaedic surgeon. A 3 x 1mm strip of tendon will be harvested from the superficial surface of the patellar tendon using a 14 gauge biopsy needle. Participants will be advised to avoid over use or excessive repetitive motions for 1-2 days Tenocyte Injection Approximately 4 weeks post-biopsy, the orthopaedic surgeon is provided with 2 vials containing 1ml each of autologous human tenocytes (2-5 x 106 cells/ml) suspended in 10% autologous human serum. Under ultrasound guidance, using an 18-gauge needle, the surgeon will inject the suspension as described above into the tendinopathy site at the extensor carpi radialis brevis (ECRB) tendon. The final volume injected will be determined by the surgeon during the procedure according to the capacity of the anatomical site. Participants will be advised to rest for two days and restrict activity to light household/office duties for four weeks.
