Wedge High Tibial Osteotomy

Background: Subchondral insufficiency fracture of the knee (SIFK) is characterized by a subchondral lesion that may lead to end-stage osteoarthritis (OA). In patients who have SIFK in a precollapse state with varus malalignment, a joint-preserving technique such as open wedge high tibial osteotomy (OWHTO) should be considered. Purpose: To evaluate the efficacy of OWHTO in primary OA and SIFK-dominant OA by clinical and radiological evaluations including magnetic resonance imaging (MRI). Study Design: Cohort study; Level of evidence 3. Methods: A total of 33 SIFK-dominant OA knees and 66 with primary OA that underwent biplanar OWHTO between March 2014 and February 2016 were included after 1:2 propensity score matching. The MRI Osteoarthritis Knee Score was used to assess bone marrow lesions (BMLs) preoperatively and at follow-up. The weightbearing line ratio, the hip-knee-ankle angle, and the joint line convergence angle were measured. The clinical outcomes assessed were range of motion, the American Knee Society Score, and the Western Ontario and McMaster University (WOMAC) score. Results: The mean follow-up period was 41.2 ± 12.6 months. The distribution of preoperative BML grade in the SIFK-dominant OA group was significantly higher in both the femur and tibia ( P < .001 and <.001, respectively) than that in the primary OA group. However, the difference was not significant postoperatively (femur, P = .425; tibia, P = .462). In both groups, postoperative BMLs showed significant improvement compared with preoperative BMLs (primary OA [femur, P < .001; tibia, P = .001] and SIFK-dominant OA [femur, P < .001; tibia, P < .001]). The WOMAC pain score was higher in the SIFK-dominant OA group preoperatively (primary OA, 7.0 ± 3.73; SIFK-dominant OA, 9.17 ± 2.6; P = .032) even though it was not different at the final follow-up (primary OA, 2.11 ± 1.7; SIFK-dominant OA, 1.79 ± 1.32; P = .179). Conclusion: OWHTO is an effective procedure not only for primary OA but also for SIFK-dominant OA. OWHTO can improve BMLs, which represent the main pathological feature of SIFK. Therefore, in patients who have SIFK with varus malalignment, OWHTO can be an attractive treatment option for preserving the joint and enhancing subchondral bone healing.

Objectives: The purpose of this study is to evaluate the clinical efficacy of open-wedge high tibial osteotomy (HTO) in treatment of kellgren- lawrence IV anterior medial knee osteoarthritis with varus tibia. Methods: Between 2016 and 2018, 56 patients with kellgren -lawrence IV knee osteoarthritis associated with varus tibial deformity who underwent a medial open-wedge high tibial osteotomy at a tertiary hospital were prospectively followed up. The surgical effect and postoperative complications were observed and analyzed. Meanwhile, the hospital for special surgery (HSS) scores of knee function before operation and at the last follow-up after operation was compared. Results: The median follow up was 19.8 months (range, 18 to 24 months). At the last follow-up, there was 40 excellent cases, 14 good cases, 2 fair case and 0 poor case. There were no complications such as vascular and nerve injury, internal fixation fracture and infection. The HSS score of knee function (89.6±3.9) at the last follow-up after operation was higher than (63.2±6.4) points before operation, and the difference was statistically significant ( P ＜0.05). Conclusion: Medial opening high tibial osteotomy shows remarkable therapeutic effect for patients with knee osteoarthritis associated with varus tibial deformity, and it can effectively relief the pain of knee joint with less postoperative complications.

Abstract Purpose This study aimed to investigate the rate at which patients returned to sports after open wedge high tibial osteotomy and identify the continuity of sports activity post-operatively. Methods Thirty-five patients (40 knees) who underwent open-wedge high tibial osteotomy (OW-HTO) in medial knee osteoarthritis were included in this study. The mean age of the patients who underwent surgery was 55.1 ± 10.7 years, and the mean follow-up period was 41.0 ± 24.7 months. Clinical results and radiographic parameters calculated in standing whole-leg radiographs preoperatively, post-operatively, and at the final follow-up were evaluated. Results Thirty-one patients (88.6%) were able to return to preoperative sports activity; however, only 14 patients (40.0%) completely returned to preoperative sports activity levels. Of the 31 patients who returned to sports activity, 10 patients (32.3%) maintained post-operative sporting activity levels at the final follow-up. In radiographic parameters, the weight-bearing line ratio was considered loss of correction in the post-operative period leading to the final follow-up. Patients who completely returned to sports and maintained sporting activity levels at the final follow-up had significantly higher the Knee Injury and Osteoarthritis Outcome Score pain subscale values and lower visual analogue scale of knee pain at pre-surgery and final follow-up than other patients, including those who partially returned to sports. Conclusions The proportion of patients who returned to sports after OW-HTO and were able to participate in competitions at the same activity level as before surgery was low and insufficient.

Background: High Tibial Osteotomy (HTO) is an approved surgical technique for varus knee deformity. For open wedge HTO multiple fixation methods and devices have been used. Advantages and disadvantages of these methods and devices are reported in various studies. Few studies have been conducted on use and final outcome of correction of varus knee deformity by implementation of non locking plates and benefits of this method is not fully evaluated. Objectives: To assess clinical and radiographic features of non-locking 4.5 millimeter L-buttress plate and T-buttress plate, which is used in open wedge High Tibial Osteotomy (HTO), and to find out whether this device is efficient enough or not. Methods: This cross-sectional study was conducted on 39 patients with tibial deformity recruited from a referral orthopedic hospital in Iran. Patients’ information, including their baseline characteristics, Range of Motion (ROM) of the knee, comorbidities, time of weight-bearing, union time in x-ray, graft type, and time of follow-up were reported at two stages: before and after the operation. Radiographic images were taken from their legs in both stages. Although different surgeons operated on the cases, they all used the same method. After the surgery, they were checked up in 2, 6, 12, and 24 weeks and a second alignment view was taken from the patients. Results: Thirty-nine patients underwent surgery for the correction of genu varus deformity and the follow-up time was between 6-48 months. There was no case of non-union and the ROM was perfectly restored in all the patients. Conclusion: Although the rate of the success in the use of the locking plate in HTO is higher, the use of a 4.5-mm non-locking plate seems to have decent results, too; therefore, it could be used as an alternative yet functional fixation tool in HTO.
