Knee stability, athletic performance and sport-specific tasks in non-professional soccer players after ACL reconstruction: comparing trans-tibial and antero-medial portal techniques.

Background: a wrong position of bone tunnels, in particular on the femur, is one of the most frequent causes of a failed anterior cruciate ligament (ACL) reconstruction. Several studies demonstrated that drilling the femoral tunnel through the antero-medial portal (AMP) allows a more anatomical placement on the lateral femoral condyle and higher knee stability, compared to trans-tibial (TT) technique. The aim of this study was to retrospectively evaluate two groups of soccer players operated on for ACL reconstruction according to either one of these two techniques.

Flat foot: a comparison of surgical methods.

The authors present a comparative review of cases concerning the results obtained in the treatment of idiopathic flat foot: the methods compared were Castaman exosinotarsal arthrorisis and Giannini endosinotarsal arthrorisis. Between 1990 and 1198 a total of 80 patients, of which 40 with calcaneo-stop, and 40 with Giannini screws, were submitted to surgery at the Orthopaedic and Traumatology Department of the University of Rome "La Sapienza". The clinical, radiographic and functional results were classified as good, fair and poor.

Prevalence of hepatitis B and hepatitis C in an orthopaedics and traumatology ward.

The prevalence of hepatitis C (HCV) was studied in the operative practice of one surgeon for a period of 18 months (1/1/98-31/6/99). Patients were also tested for measurement of liver enzymes, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and hepatitis B virus surface antigen (HbsAg). Out of a total of 911 consecutive patients, 37 (4.

Epiphysiolysis of the hip: relationship between etiopathogenesis and hormone status.

The authors present a review of the literature on the etiology of epiphysiolysis of the hip and an original study on the hormone status of these patients. By examining eleven values including hormones, vector proteins, and hormonal transport, the authors related the data obtained to the anagraphical age of the patient, to his or her skeletal age, to the development of sexual features, and to the radiologic evidence of pathology. In light of the results obtained, despite the fact that the study only included 23 patients, the modified equilibrium between SHBG and Somatomedin C, would seem to lead to an accelerated turnover in the growth plate.
