Hence, HTO cannot correct the intra-articular deformity of the knee in patients with moderate/severe medial OA.Д®valuation of Deformities of the Lower Limbs and the Principles of Deformity Correction However, HTO, which cuts the proximal part of the tibia, is an extra-articular correction. Changes of the medial meniscus, cartilage, medial femoral condyle, and lateral femoral condyle of the moderate/severe medial OA knee represent an intra-articular deformity of the knee joint. Kettlekamp reports that HTO is not indicated for the teeter knee because of these reasons. Patients who are experiencing this will often complain about the lateral thrust of the knee joint while walking. As a result, both condyles of the knee in patients with moderate/severe medial OA cannot make contact with the tibial articular surface simultaneously.

Next, the medial femoral condyle is subluxated medially, and then the lateral femoral condyle is detached from the lateral tibial articular surface. In the next stage, the cartilage of the medial joint is worn. With increasing degeneration and progression to moderate/severe medial OA, the medial meniscus subluxates medially. (c) A 74-year-old female with most severe medial osteoarthritis treated with sliding osteotomy and total knee replacement (b) An 80-year-old female with moderate medial osteoarthritis treated with total knee replacement. As a result, the pain in the medial joint is eliminated.ДЇigure 1: (a) An 67-year-old man with mild medial osteoarthritis knee treated with dome high tibial osteotomy fixed with Charnley external fixator. Therefore, the load on the medial joint that has the ruptured meniscus and the defect of the cartilage is decreased, and the load on the lateral joint that has the normal lateral meniscus and the normal cartilage is increased after HTO. After HTO, the force diagram of the knee in patients with medial OA is shifted from the medial side to the lateral side of the knee joint. HTO osteotomizes the proximal part of the tibia and corrects the varus deformity. Hemiarthroplasty and TKA are indicated for the treatment of moderate and severe medial OA. HTO is typically indicated for the treatment of mild and moderate medial OA. Surgical treatments for medial knee osteoarthritis (medial OA) include high tibial osteotomy (HTO), hemiarthroplasty (Hemi), and total knee arthroplasty (TKA). Keywords:В High tibial osteotomy, knee joint, medial, osteoarthritis, tibial condylar valgus osteotomy If the correction of varus and the mechanical axis is not enough, then extra-articular deformity must also be corrected, with a simultaneous or subsequent HTO. Intra-articular deformity must be corrected first. To conclude, in cases of medial OA knee, the type of deformity must be evaluated and corrected accordingly. TCVO also improves the bony stability, eliminates the lateral thrust and surely corrects the alignment of the lower limb. The contact area of the articular surface of the knee joint after TCVO is broader than it is after HTO in cases of moderate/severe OA. Thus, an intra-articular osteotomy like the Tibial condylar valgus osteotomy (TCVO) is required in cases of moderate to severe medial OA knee. HTO cannot correct these intra-articular deformities. Thus HTO, which is an extra-articular osteotomy, is recommended for the treatment of mild OA, but in moderate and severe medial OA, there are intra-articular deformities.

In the early stages of medial OA, there are no intra-articular deformities. The medial compartment osteoarthritis (OA) of knee joint has various surgical options such as high tibial osteotomy (HTO), hemiarthroplasty, and total knee arthroplasty.
