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.

Moreover, UKAs may require a smaller incision, less tissue damage, and faster recovery times. [2] In the United States, the procedure constitutes approximately 8% of knee arthroplasties. [4] In comparisons with a more extensive surgical procedure called high tibial osteotomy, UKA has equal or better outcomes. [1] [5]
The location of the removed wedge of bone depends on where osteoarthritis has damaged the knee cartilage. The most common type of osteotomy performed on arthritic knees is a high tibial osteotomy, which addresses cartilage damage on the inside (medial) portion of the knee. The procedure usually takes 60 to 90 minutes to perform. [9]
The recovery period may be 12 weeks or longer and may involve the use of mobility aids (e.g. walking frames, canes, crutches) to enable the patient's return to preoperative mobility. [4] It is estimated that approximately 82% of total knee replacements will last 25 years.
In elderly people this usually would include ECG, urine tests, hematology and blood tests. Cross match of blood is routine also, as a high percentage of people receive a blood transfusion. Pre-operative planning requires accurate Xrays of the affected joint, implant design selecting and size-matching to the xray images (a process known as ...
One study has shown a success rate of 75 to 80 percent among patients 45 years of age or younger. [21] [22] It is an outpatient procedure and causes only small discomfort. The harder part is the restrictions that are placed on the patient during the post-operative recovery period. This can be a major challenge for many patients.
