Multiple Instrumentation for ACL Reconstruction Regarding Bacterial Contamination

Infection is a catastrophic and one of the most dreaded complications in orthopaedic surgery. Several measures have been undertaken to reduce the risk of infection, one of which is the use of systemic prophylactic antibiotics. The purpose of this study is to determine the effect of multiple instrumentation regarding bacterial contamination in transportal and transtibial techniques in ACL reconstruction . About Eighty consecutive patients having surgical indication for ACL-R will be included, the cases will be divided into two groups, 35 cases will undergo for the transtibial technique and the other 45 cases will undergo for the transportal technique. After preparation, swabs will be obtained from subcutaneous tissue at antromedial portal track in transportal technique (femoral tunnel drilling) and in transtibial technique before and after the instrumentation and femoral screw insertion, a control sample will be taken at antrolateral track in both techniques, then samples will be sended to the lab to be studied.
