A Prospective, Multi-center, Randomized Clinical Study to Evaluate the Safety and Effectiveness of Biosure Regenesorb Interference Screw in Arthroscopic Reconstruction of Cruciate Ligaments in Chinese Patients
In Brief
A clinical study evaluating Investigational device: Biosure Regenesorb Interference Screw and Control device: BIOSURE HA Interference Screw for Cruciate Ligament Reconstruction and Knee. Completed, enrolled 140 participants across 4 sites.
Detailed Summary
The objective of this study is to compare the safety and effectiveness of Biosure Regenesorb Interference Screw versus BIOSURE HA Interference Screw (control device) in patients requiring reconstruction of cruciate ligaments of the knee. The trial results will be used for registration of Biosure Regenesorb Interference Screw in China. The primary efficacy endpoint of this study is Lysholm score at 12 months after operation. The non-inferiority testing is performed for efficiency of primary efficacy endpoint, and the test hypothesis is as follows: Invalid hypothesis: H0: μ1-μ2 ≤-δ Alternative hypothesis: H1: μ1-μ2 \> -δ, where, μ1 and μ2 are the Lysholm scores in the investigational group and control group, respectively. δ is a non-inferiority critical value.

Timeline
Interventions
The Biosure Regenesorb Interference Screw, an absorbable screw designed with an open structure and made of biocomposite material made of PLGA, β-TCP and calcium sulfate, is used to fix ligaments, tendons, soft tissues or bone-tendon-bone grafts in knee surgery. Its open structural design enables rapid bone ingrowth to make the screw integrated with bone tissues so as to promote healing.
BIOSURE HA Interference Screws and Drivers are designed for durability and reduced screw breakage. Both the screws and driver have been enhanced to allow screws to fully seat on the driver all the way to the tip of the screw, helping stress distribution and force transfer. The screw design also incorporates a consistent wall thickness throughout the length of the screw for added durability and features a tapered body for ideal ease of insertion.
