Interference Screw Mectascrew-C Postmarket Study

Study Overview
=================
Brief Summary
-----------------
An observational prospective study with the aim to analyze the presence at 6 months of a specific composite IS (Medacta Mectascrew C) in the reconstructive treatment of ruptured ACL or PCL by means of an autograft or allograft.

Detailed Description
-----------------
This is an observational prospective study with the aim to determine the presence of the composite IS (Mectascrew-C) at 6 months following ACL or PCL reconstruction. Patients with an ACL or PCL tear scheduled for surgery at one of the EOC's hospitals will be enrolled in the study, after the subscription of informed consent. The injured ligament will be restored with an auto- or allograft that will be fixed with a composite IS (Mectascrew-C, 70% PLDLLA, 30% β-TCP, Medacta International SA). The data will be collected from patient's medical histories (data about diagnosis, patients' characteristics and surgery) and after operation, during the orthopaedic follow-up visits, planned at 1, 3 and 6 months, in order to assess the functional outcomes (IKDC objective and subjective) and the knee stability (ROM, Pivot Shift or Reverse Pivot Shift test, anterior or posterior drawer test) of the patients. The treated knee will be also evaluated radiologically with an MRI at 6 months to assess the IS reabsorption. The results of this exam will be correlated to the pre-operative findings and to the functional and clinical outcomes evaluated with the different forms

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Interference screw presence | via MRI imaging at 6 months after surgery, the presence of the Mectascrew-C will be assessed | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mobility outcomes evaluation | Assessment throught Range Of Motion of operated knee calculated as degree | 1, 3 and 6 months | 
| Functional outcomes evaluation | Assessment throught IKCD score. a patient-completed tool, which contains sections on knee symptoms (7 items), function (2 items), and sports activities (2 items). Scores range from 0 points (lowest level of function or highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms). | 1, 3 and 6 months | 
| Knee stability evaluation of ACL intervention | Pivot shift test. A positive test indicate an injury at ACL | 1, 3 and 6 months | 
| ACL integrity assessment | Anterior drawer test. An anterior translation more than 6 mm indicate a positive test with injuried ACL | 1, 3 and 6 months | 
| Knee stability evaluation of PCL intervention | Reverse Pivot Shift test. In the presence of a posterolateral injury with the knee flexed, the tibia follows gravity and drops into posterolateral subluxation (positive Reverse Pivot Shift Test). | 1, 3 and 6 months | 
| PCL integrity assessment | Posterior drawer test. The test is considered positive if there is a lack of end feel or excessive posterior translation. | 1, 3 and 6 months | 
| Device safety evaluation | collection of adverse event | 1, 3 and 6 months |
