Unlabelled: Anticardiolipin antibodies (aCL) are present in 24-61% of patients (pts) with systemic lupus erythematosus (SLE). It is suggested that they may be associated with valvular abnormalities recognized on echocardiography (ECHO). To evaluate the relation of raised aCL and cardiac abnormalities we performed ECHO in 48 pts with SLE. ACL were estimated in all pts using enzyme-linked immunoabsorbent assay (ELISA), and positive result was found in 25 pts (52%), negative in 23 pts (48%). Abnormalities on ECHO were found in 18 pts in aCL(+) group vs 4 pts in aCL(-) group (68 vs 17% respectively; p < 0.01). Valvular abnormalities were present in 9 pts in aCL(+) group and in 4 ts in aCL(-) group (36 vs 17%; p = n.s.), pericardial effusion in 6 pts in aCL(+) group vs 0 pts in aCL(-) group (24 vs 0%; p < 0.05).
Conclusion: We found association between raised aCL and general cardiac abnormalities on ECHO.

Correlation of Increased Lateral Tibial Slope With Baseline Tibial Position in Intact Knees and Side-to-Side Anterior Tibial Translation for Knees With ACL Tears.

Twin Cities Orthopedics, Edina, Minnesota, USA.
Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.
Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.

Purpose: Asymmetric anterior closing-wedge high tibial osteotomy (ACWHTO) allows correction of both excessive posterior tibial slope (PTS) and varus deformity. However, the complexity of this surgery requires a high degree of accuracy, which is less likely to be achieved with standard instrumentations. This study aimed to determine the accuracy of 3D patient-specific cutting guides (PSCGs) to provide the accurate planned correction in the frontal and sagittal planes.

Department of Orthopaedics and Traumatology, Aix Marseille Univ, APHM, CNRS, ISM, Sainte-Marguerite Hospital Institute for Locomotion Marseille France.
Purpose: This study assessed the measurements of the medial posterior tibial slope (MPTS) using long radiographs and three-dimensional (3D) computed tomography (CT) scans and compared them to measurements taken on short lateral knee radiographs. The study aimed to identify whether the at-risk slope measurements previously defined on the short radiographs would be similar to long radiographs and 3D CT scans.
Methods: A retrospective radiological review of 52 cases, who underwent planning for a slope-changing high tibial osteotomy and had short and long lateral radiographs and 3D CT scans of the tibia.

Osteotomy Committee of the German Knee Society (Deutsche Kniegesellschaft e.V.), Schwarzenbek, Germany.
Purpose: Different techniques of slope-decreasing anterior closed-wedge proximal tibial osteotomy (ACW-PTO) have been described. To determine the peri- and post-operative complication rate and obtain data on bone healing in ACW-PTO with an infratuberositary approach.
Methods: A total of 170 consecutive ACW-PTO of two sports-orthopaedic centres were retrospectively evaluated (97 and 73, respectively).
Cut-off value for the posterior tibial slope indicating the risk for retear of the anterior cruciate ligament.

Sportsclinic Hellersen, Lüdenscheid, Germany.
Purpose: The significance of the posterior tibial slope (PTS) has increasingly come into focus in anterior cruciate ligament (ACL) reconstruction being a risk factor for ACL graft failure. Nevertheless, inconsistent data on the critical value of the PTS exist. The purpose of this study was to define a cut-off value for the PTS in ACL surgery.
