High tibial osteotomy is an orthopaedic surgical procedure which aims to correct a varus deformation with compartmental osteoarthritis.Since the inception of the procedure, advancements to technique, fixation devices, and a better understanding of patient selection has allowed HTO to become more popular in younger, more active patients hoping to combat arthritis.

Children until the age of 3 to 4 have a degree of genu varum. The child sits with the soles of the feet facing one another; the tibia and femur are curved outwards; and, if the limbs are extended, although the ankles are in contact, there is a distinct space between the knee-joints.
During a high tibial osteotomy, surgeons remove a wedge of bone from the outside of the knee, which causes the leg to bend slightly inward. This resembles the realigning of a bowlegged knee to a knock-kneed position. The patient's weight is transferred to the outside (lateral) portion of the knee, where the cartilage is still healthy. [10]
A flattened or slightly dished high-density polyethylene surface is then inserted onto the tibial component so the weight is transferred metal to plastic, not metal to metal. During the operation any deformities must be corrected, and the ligaments balanced so the knee has a good range of movement, and is stable and aligned.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
High quality MRI images (1.5 T magnet or higher [22]) of the knee can be extremely useful to diagnose injuries to the posterolateral corner and other major structures of the knee. [23] While the standard coronal , sagittal and axial films are useful, thin slice (2 mm ) coronal oblique images should also be obtained when looking for PLC injuries.
The POL (called by older texts: oblique portion of the sMCL) is a fascial expansion with three main components: superficial, central (tibial), and capsular. The central arm is the strongest and thickest. [2] [10] It arises from the semimembranosus tendon and connects anterior and distal to the gastrocnemius tubercle via the posterior joint ...
Medial tibial stress syndrome: Pain occurs over the shin bone (the tibia) with running or other sport-related activity. [17] Fibular and tibial stress fracture: Non-displaced microscopic fracture of the fibular and tibia occurs in many athletes, especially runners, and also in non-athletes who suddenly increase their activity level.
