To measure the posterior slope of tibia among healthy Saudi population using Magnetic Resonance Imaging (MRI). A retrospective study review 151 knee MRIs at King Khaled University Hospital, Riyadh, Arabia. All patients with no previous surgical intervention to their knees and did not suffer any bone injury around were included. Three different orthopedic physicians (two senior residents, one fe...

Objetive: One major cause of Medial Opening-Wedge High Tibial Osteotomy (MOW-HTO) failure is inadvertent Posterior Tibial Slope (PTS) increase. To avoid this complication, posterior placement of the wedge plate is traditionally recommended. However, in the attempt of achieving such positioning, surgeon may encounter some undesired consequences, like medial collateral ligament disruption, instab...

Total Knee Arthroplasty (TKA) has been considered as a standard procedure for intractable pain in the end-stage degenerative arthritis of the knee and maintaining range of motion (ROM) to facilitate the ability to perform daily living activities. 1 Factors that have been associated with the change in ROM after TKA include preoperative ROM, implant design, patient characteristics, posterior femo...

Anterior cruciate ligament (ACL) is the primary stabilizer of the knee. An impairment of any of the dynamic or static stability providing factors can lead to overload on the other factors and ultimately to deterioration of knee stability. This can result in anterior tibial translation and rupture of the ACL. The purpose of this study was to examine the influence of tibial slope on ACL injury ri...

Failed reconstruction of the anterior cruciate ligament (ACL) in a young, active patient represents a difficult clinical problem. Numerous factors contribute to failure, including repeat trauma, technical errors, biologic influences, or a combination of causes. Technical errors commonly include femoral and tibial tunnel malposition, inadequate graft fixation, failure to address associated poste...

Radiographs of 110 patients who had undergone 120 high tibial osteotomies (60 closed-wedge, 60 open-wedge) were assessed for posterior tibial slope before and after operation, and before removal of the hardware. In the closed-wedge group the mean slope was 5.7 degrees (SD 3.8) before and 2.4 degrees (SD 3.9) immediately after operation, and 2.4 degrees (SD 3.4) before removal of the hardware. I...
