ClinConnect Summary

This clinical trial is studying the long-term outcomes of a specific knee surgery called revision anterior cruciate ligament (ACL) reconstruction. This surgery is performed on patients who have previously had ACL surgery that did not fully heal or work as expected. In this trial, researchers are focusing on a technique that uses a single-bundle approach combined with an external support method, using a graft from a donor's Achilles tendon. The goal is to see how well this surgical method works over time and to understand the risks, such as the potential development of arthritis in the knee.

To participate in this study, patients need to be between 18 and 50 years old and have undergone the specific type of revision surgery at least two years ago. They also need to have provided consent to take part in the study and have a radiograph (an X-ray) of their knee taken around the time of their surgery. However, those with advanced knee arthritis, severe obesity, or other significant health issues will not be eligible. Participants can expect to contribute to valuable research that could help improve future ACL surgeries and outcomes for others.
