Arthroscopic Coracoclavicular Ligament Reconstruction Comparing Two Techniques
A study testing Coracoclavicular ligament reconstruction in people with AC Joint Dislocation, run by University of Turku at 1 site in Finland.
Trial summary
This study follows early wound healing using knot hiding titanium implants in coracoclavicular ligament reconstruction. A further aim is to compare two techniques where the semitendinosus tendon graft either runs through the coracoid drill hole or goes around the coracoid. Read more about this study

About this study
Official title: Arthroscopic Coracoclavicular Ligament Reconstruction Using Knot Hiding Titanium Implants: a Prospective Randomized Two-year Follow up Study Comparing Two Techniques
This study follows early wound healing using knot hiding titanium implants in coracoclavicular ligament reconstruction. A further aim is to compare two techniques where the semitendinosus tendon graft either runs through the coracoid drill hole or goes around the coracoid.
Read the detailed description
A modified arthroscopic technique for coracoclavicular ligament reconstruction was used based on a previous technique where the supportive device and the semi tendon graft share the clavicular and coracoid drill holes. A notable problem with the previous technique was large protruding suture knots on the washer and clavicle, which could predispose to wound infection. In this new modified technique, new implants were introduced. The new implant hides the suture knot and less foreign material is needed.
The purpose of this study is to follow the patients operated using the new implants with special attention to early clavicular wound healing. A further aim is to compare a technique where the semitendinosus graft runs through clavicular and coracoid drill holes versus a technique where the graft runs under the coracoid process.
