Overview
Brief Summary
The purpose of this study is to evaluate the long-term results of various anterior cruciate ligament reconstruction techniques. This assessment is necessary for the current context of anterior cruciate ligament research as several techniques and grafts are used in clinical practice, however, the various studies existing in the literature focus mainly only on the direct comparison of two techniques and usually with short-to-medium term follow-up. Since gonarthrosis is one of the most debated consequences of cruciate ligament reconstruction, a comparison of different long-term procedures would be desirable to have a clearer picture of the risks and benefits associated with different types of intervention.
Detailed Description
In the beginning, the Database of our Institute is consulted, all the patients that underwent ACL reconstruction at least 15 years ago are selected. The original group will be divided into subgroups based on the surgical technique adopted, of the different techniques we took into consideration only these three: anatomical ACL reconstruction with patellar tendon, anatomical ACL reconstruction with hamstrings, non-anatomical ACL reconstruction "Over-the-top plus lateral plasty". The patients will be contacted to ask if they are interested to take part in the study; at least 25 patients for each group will be recruited. All the patients recruited will sign an informed consent about the study and the personal data treatment. After consent acquisition, patients will undergo a clinical examination and a questionnaire about pain and knee status will be administered; moreover, a radiographical examination of the operated knee will be performed to assess the osteoarthritis progression. Patients that reported graft rupture will be registered as failures.
