Performance and Safety of the Polylactic Interference Screw Used in Anterior Cruciate Ligament Reconstructions

The evaluation of the clinical data has demonstrated the conformity of the Polylactic Interference Screw (PIS), with the relevant essential requirements for its use in orthopaedic applications. The Polylactic Interference Screws are intended for tibial and femoral ligament/graft fixation in the case or Anterior Cruciate Ligament (ACL) reconstructions. It has been concluded that the risks associated with the use of the device are acceptable when weighted against the benefits to the patients. In order to improve the clinical data on the PIS, the manufacturer, Biomatlante, decided to assess that the performance and safety of the device are maintained until the reaching of its intended use. In this objective, the goal of this study will be to observe the following parameters:

Objective IKDC score (clinical evaluation) Subjective IKDS score (functional evaluation) Safety (report of any adverse event) Follow-up of the patient's recovery

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change of the objective International Knee Documentation Committee score before and after surgery	Record of the objective International Knee Documentation Committee score (A = normal, B = almost normal, C = abnormal or D = very abnormal)	4 months before surgery / 7 months post-surgery
Change of the subjective International Knee Documentation Committee score before and after surgery	Record of the subjective International Knee Documentation Committee score (from 1 to 100 where 100 is the best result)	4 months before surgery / 7 months post-surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number and precise description of any adverse event during the follow-up	Record and description of any adverse event during the follow-up that reflects the safety of the Polylactic Interference Screw	Before surgery until 7 months post-surgery
Change in the patients recovery	Record of specific items of the Objective International Knee Documentation Committee score reflecting the patients recovery	2 months post-surgery
