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.

This procedure is used when a portion of an extremity is injured or involved with a disease, such as cancer. [1] The procedure is most commonly used to transfer the ankle joint to the knee joint following removal of a distal femoral bone tumor, such as osteosarcoma. The limb is rotated because the ankle flexes in the opposite direction compared ...
Arthroplasty (literally "[re-]forming of joint") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure. It is an elective procedure that is done to relieve pain and restore function to the joint after damage by arthritis or some other ...
The tibial plateau leveling osteotomy and tibial tuberosity advancement are two of the most common osteotomy procedures performed in the United States. Recovery is often 6–8 weeks and the osteotomy can be filled with autologous bone grafts, scaffolds (hydroxyapatite, TR Matrix, etc.) or ceramics. [14]
An ankle fracture is a break of one or more of the bones that make up the ankle joint. [1] Symptoms may include pain, swelling, bruising, and an inability to walk on the injured leg. [1] Complications may include an associated high ankle sprain, compartment syndrome, stiffness, malunion, and post-traumatic arthritis. [1] [2]
Syndesmosis procedure is one of the more than twenty bunion surgeries currently being performed. While the majority of bunion surgeries involve the breaking and shifting of bones (osteotomy procedures), [1] syndesmosis procedure [2] is one of few surgical techniques that use a soft-tissue or non-osteotomy (non-bone-breaking) approach to afford the same correction.
Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis , i.e. fusion of the bones.
Hip-knee-ankle angle. On projectional radiography, the degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [7] which is an angle between the femoral mechanical axis and the center of the ankle joint. [8] It is normally between 1.0° and 1.5° of varus in adults. [9] Normal ranges are different in children. [10]
