Tendon injuries are one of the most common musculoskeletal complaints reported to general practitioners, with shoulder pain affecting more than 50% of adults over the age of 50. Mostly frequently, shoulder pain is the result of damage to the rotator cuff tendon. Rotator cuff tendon tears have a significant impact on the individual, not only affecting their ability to work or play sport, but also those common daily tasks that we take for granted, like dressing, having a shower, or even getting a good night’s sleep.

Surgery to repair rotator cuff tendons is problematic because the underlying tendon is weakened and re-tears are very common. Re-tears require additional surgery to repair the damage. Orthocell’s CelGro™ collagen membrane assists in strengthening the surgical repair of damaged or torn tendons to restore function and relieve pain.

 
 

Promising Clinical Results

The performance of CelGro™ when used to augment repair of rotator cuff tendinopathy and tear was recently evaluated in a clinical trial. Two years after their surgery, 89% of patients reported that they were pain free and had normal shoulder function, and a further 11% reported that their shoulder function was better than before the surgery. No patients needed more surgery to fix a re-tear.

Patients reported significant improvements in their ability to dress themselves and sleep at night, and were back at work and playing sport without discomfort or pain. 

“ The tendon in my right shoulder was frayed at the ends and difficult to repair because I’d left it so long. When Dr Wang said that being in the CelGro™ study might improve outcomes, I thought it would be worth trying. I’m an active person and wanted long-lasting mobility, without going under the knife again and again. That’s why CelGro™ made sense for me. So much so, I have gone back to get my other shoulder done.” - Ken Winfield, trial participant

Strengthening Tendon Repair

Current surgical repairs are performed with great skill, but unfortunately there is a high rate of failure. The repaired tendon is often weaker, due to the poor quality of the tendon tissue, and prone to re-tear. CelGro™ was designed with handling characteristics to assist surgeons perform reconstructive procedures, while creating a unique healing environment to improve the quality of the regenerated tendon tissue. Better quality tissue strengthens the repair and reduces the risk of re-tear.

“Rotator cuff repair can be a challenging area. An effective biological augment to surgical repair is increasingly desired by the orthopaedic community. CelGro™ has been shown to improve tissue healing and assists in reducing the surgical revision rate of rotator cuff tendon.”  – Professor Alan Wang, Orthopaedic surgeon and CelGro™ trial Principal Investigator

More about CelGro™  

CelGro™ is a unique collagen medical device intended for use in tissue regeneration and repair. CelGro™ enhances tendon regeneration in three different ways. 

  1. CelGro™ creates a bio-active healing environment to improve the quality of tissue repair

  2. CelGro™ facilitates and promotes higher quality tissue repair, reducing the risk of re-tear

  3. CelGro™ can be used in tendons at multiple sites throughout the body
