Overview
- Currently rotator cuff repair (RCR) surgery is performed mainly under the double row approach. Costing a total of US$4,000, four suture anchors are needed in a single surgery—a complicated procedure that takes two hours or so. Indeed, it is inefficient and expensive.
- The team has thus come up with a more efficient and economical RCR alternative.
- In addition to shortening surgical time, the procedure renders bolstered biomechanical strength to attain a firm and secure stitching outcome, thereby mitigating the risk of tendon re-tear.
Development Process
Over the course of this project under the Applied Research Incubation Program, the team completed biomechanical strength testing; biocompatibility tests—cytoxicity test, intracutaneous irritation test, skin sensitivity test, acute systemic toxicity test, pyrogen test—for ISO 10993 compliance; functionality assays. Animal tests and preparations for a pre-submission to the FDA are now under way.
