Autologous Tenocyte Implantation (ATI) and the Use of Collagen Scaffolds: a Case Report of a Novel Surgical Treatment for Gluteal Tendon Repair

This case report describes the treatment of a 63-year old female with extensive history of lateral hip pain and treatment-refractory tendinopathy with tearing. The patient underwent open surgery to repair the gluteus medius tendon, using supplementary autologous tenocyte implantation in conjunction with a CelGro collagen scaffold. At 12 months post-treatment, patient had normal function, and MRI scans showed markedly reduced inflammation of the tendon and reduced atrophic changes in muscle belly.

    Collagen Membrane for Guided Bone Regeneration in Dental and Orthopedic Applications

    This paper describes the material characterisation of CelGro collagen membrane, a preclincal model for cortical bone regeneration, and a human study of guided bone regeneration in dental implant surgery. The study showcases the versatility of CelGro as a regenerative medicine scaffold that may be used in different clinical indications.

 Autologous Tenocyte Injection for the Treatment of Chronic Recalcitrant Gluteal Tendinopathy - A Prospective Pilot Study. 

Clinical study of Ortho-ATI® treatment in patients with chronic gluteal tendinopathy with symptom duration greater than six months, and failure to respond to conservative treatments, including corticosteroid injection. Ortho-ATI® treatment significantly improved clinical outcomes such as pain and disability at 12 and 24 months post treatment.

A Biphasic Bone Substitute with Gentamycin Regenerates Bone in Osteomyelitis with Muscle Acting as an Osteoinductive Niche. 

Bone substitute with gentamycin leads to new bone cells and growth. Clinical observations with rapid bone formed in the bone substitute, and in some cases in the muscle, are a consequence of both leakage of bone active proteins and also from cells coming from the overlaying muscle interacting with the bone substitute.

Evidence for the Durability of Autologous Tenocyte Injection for Treatment of Chronic Resistant Lateral Epicondylitis - Mean 4.5 Year Clinical Follow-up.

This was a clinical study of Ortho-ATI® in patients with tennis elbow, whose symptom duration was greater than six months, and failed to respond to conservative treatments, including corticosteroid injection. Ortho-ATI® treatment significantly improved clinical function (pain, disability and grip strength) and tendon structure for up to 5 years after treatment.

Autologous Tenocyte Injection for the Treatment of Severe, Chronic Resistant Lateral Epicondylitis: A Pilot Study’ Wang A et al. American Journal of Sports Medicine (2013)   

In this study, patients with chronic LE who had previously undergone an unsuccessful full course of nonoperative treatment showed significantly improved clinical function and structural repair at the origin of the common extensor tendon after ATI. This novel treatment is encouraging for the treatment of tendinopathy and warrants further evaluation.

Autologous Tenocyte Implantation, A Novel Treatment for Partial-Thickness Rotator Cuff Tear and Tendinopathy in an Elite Athlete. 

In this clinical case study of Ortho-ATI® treatment for rotator cuff injury in an elite gymnast, the patient reported substantial improvements in pain and function at one year after treatment. MRI scan showed that the tendinopathy had improved with complete healing of the tendon tear.

Autologous Tenocyte Therapy for Experimental Achilles Tendinopathy in a Rabbit Model.’ Chen J et al., Tissue Engineering (2011) Part A, Volume 17 (15-16), pp. 2037-48.  

Autologous tenocyte treatment (ATT) improved tendon remodeling, histological outcomes, collagen content, and tensile strength of tendinopathic Achilles tendons.  This study suggests ATT may be a useful treatment of chronic Achilles tendinopathy.

‘In Chronic Lateral Epicondylitis, Apoptosis and Autophagic Cell Death Occur In The Extensor Carpi Radialis Brevis Tendon’. Chen J et al., J Elbow and Shoulder Surg. (2010), Volume 19, pp. 355-62. 

This study demonstrated that cell death occurs in the ECRB tendon in chronic lateral epicondylitis. The markedly elevated cell death rate in the grade II cell matrix may be responsible for the decrease in cellularity and further deterioration of collagen quality seen in end-stage grade III matrix. This eventually compromised the tendon's ability to maintain its integrity and resulted in tendon tear. The study suggests cell death plays an important role in the development of tendon degeneration in chronic lateral epicondylitis.

Autologous Tenocyte Therapy Using Porcine Derived Bio-scaffolds for Massive Rotator Cuff Defects in Rabbits’. Chen J et al., Tissue Engineering (2007) Volume 13 (7), pp. 1479-91

This study suggests the implantation of autologous tenocytes on collagen-based bioscaffolds results in better rotator cuff tendon healing and remodeling than with the implantation of bioscaffold alone.
