Abstract Background Maintenance of optimal knee joint line orientation (KJLO) is important after high tibial osteotomy (HTO). No tools, however, are currently available that could predict the value of postoperative KJLO before surgery. First, this study sought to determine the effects of various preoperative anatomical alignment parameters to postoperative KJLO. Based upon these analyses, we aimed to devise an equation that predicts the value of postoperative KJLO. Methods A total of 14 radiographic parameters were measured in preoperative and postoperative full-limb standing anteroposterior radiographs on 50 patients who underwent open-wedge HTO. The parameters were analysed using multivariable linear regression to predict KJLO after HTO. External validation of the equation was done with 20 patients who underwent HTO at another institution. Results After HTO, KJLO increased from − 0.8° to 2.9° (P < 0.001). Based on the multivariable linear regression analysis, an equation was derived that can estimate postoperative KJLO after HTO; postoperative KJLO(°) = 1.029 + 0.560 × preoperative KJLO(°) + 0.310 × preoperative tibia plateau inclination(°) + 0.463 × aimed correction angle(°). The adjusted coefficients of determination value for this equation was 0.721. The equation also showed good calibration and predictability in external validation with predicted squared correlation coefficient of 0.867. Conclusions This study analysed the effects of preoperative anatomical alignment parameters on the postoperative KJLO. An equation which predicts postoperative KJLO with preoperative anatomical alignment factors was devised and validated. This equation would help in selecting optimal patients for HTO and in selecting the optimal target correction angle in HTO.

Changes in knee joint line orientation after high tibial osteotomy are the result of adaptation of the lower limb to the new alignment

Anatomical Outcome

Objective: To determine the radiological, functional, and anatomical outcome in patients with osteoarthritic knee undergoing high tibial osteotomy (HTO). Design of study: Descriptive case series. Study duration and settings: The present study was a descriptive case series carried out at the Orthopedic Departments of District Head Quarter Hospital Faisalabad affiliated with Faisalabad Medical University, Faisalabad from Jan 2014 to March 2018. Methodology: This study involved 40 patients of both genders, aged between 40 and 65 years having advanced degenerative disease of knee limited to medial compartment of joint. These patients were treated by medial open wedge high tibial osteotomy (OWHTO) and outcome was evaluated after 5 years of surgery in terms of radiological knee mechanics, functional outcome scores, and arthroscopic evidence of cartilage regeneration in the medial compartment. A signed written consent was taken from every patient. Findings: There was a female predominance with a male-to-female ratio of 1:4. The mean age of the patients was 53.2 ± 6.9 years. The values of the radiographic parameters significantly changed from pre-operative condition after HTO; mechanical tibiofemoral angle [MTFA, (−8.1 ± 1.2° vs. 2.5 ± 1.2°; p-value < 0.0001)], tibial plateau inclination [TPI, (5.3 ± 1.1° vs. 3.4 ± 1.1°; p-value < 0.0001)], knee joint line orientation relative to the ground [G-KJLO, (0.3 ± 0.1° vs. 4.6 ± 1.5°; p-value < 0.0001)], and ankle joint line orientation relative to the ground [G-AJLO (8.3 ± 3.2° vs. 2.3 ± 1.7°; p-value < 0.0001)]. There was significant improvement in patient’s functional status; KOOS-ADL score (45.5 ± 7.8 vs. 73.7 ± 8.6; p-value < 0.0001), International Knee Documentation Committee (IKDC) score (42.4 ± 6.9 vs. 68.5 ± 12.7; p-value < 0.0001), International Knee Society (IKS) score (149.4 ± 11.9 vs. 179.4 ± 10.2; p-value < 0.0001), Knee Society Score [KSS, (54.2 ± 5.6 vs. 69.7 ± 12.7; p-value < 0.0001)], and Hospital for Special Surgery [HSS, (50.8 ± 3.3 vs. 64.8 ± 10.7; p-value < 0.0001)]. 42.5% patients showed excellent regeneration of femoral and 30.0% patients showed excellent regeneration of tibial cartilage in the medial compartment. Conclusion: By significantly alternating the knee biomechanics, HTO was found to unload the medial compartment leading to regeneration of the articular cartilage and significant improvement in patient’s symptoms and quality of life. It is therefore recommended in the management of patients with arthritic changes limited to medial compartment only.

Introduction: Knee osteoarthritis is a common degenerative disease in the elderly clinically. Cartilage damage, osteophyte formation, joint space narrowing and bone exposure are the main pathological changes, mainly manifested as joint cartilage degeneration [1]. Since the knee joint load of normal people is mainly conducted through the medial side of the knee joint, it is easy to cause degeneration of the medial compartment and then narrow the joint space, which leads to the medial deviation of the lower limb line and the varus deformity of the knee joint. For patients aged 55-65 years with unilateral ventricular osteoarthritis of the knee, the current surgical methods are mostly high tibial osteotomy (HTO) or unicomartmental knee arthroplasty (UKA)[2,3]. HTO always thought to improve lower limb power line to correct deformities, effectively relieve pain and improve function, is an effective method for treatment of osteoarthritis knee inside, high cut bone is typically used in younger patients and patients from physical activity, can effectively reduce the load and delay of knee joint cartilage lesion replacement time, while UKA is more suitable for old age is not active, activity, and patients needs more intense in terms of pain relief. Hypotheses: To investigate the clinical effect of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) with tomofix internal fixation in the treatment of unicompartmental knee osteoarthritis. Methods: 60 patients with unicompartmental knee osteoarthritis and varus deformity of the knee joint were randomly divided into two groups: the UKA group (30 cases) and the HTO group (30 cases). The average follow-up time was 6 months, Scores preoperative and postoperative knee joint function, postoperative complications and postoperative pain satisfaction were compared. Results: The scores of HSS, VAS, femorotibial angle(FTA) and active range of motion(ROM) were 82.6 ± 12.9, 1.9 ± 0.8,173.2 ± 1.4,135.2 ± 1.6 in the group of unicompartmental knee arthroplasty (UKA);The scores of HSS, VAS(Visual Analogue Score), femorotibial angle(FTA) and active range of motion(ROM) after tomofix internal fixation used in the group of high tibial osteotomy (HTO)were 81.9 ± 14.3, 1.8 ± 0.9, 174.5 ± 1.8 and 121.1 ± 2.7 . There was no significant difference between the UKA group and HTO group in the scores of HSS, VAS and femorotibial angle(FTA) (P > 0.05). The active range of motion(ROM) of the HTO group was better than that of UKA group (P < 0.05). Conclusion: Both unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) with tomofix internal fixation can improve the knee joint function and symptoms in the treatment of medial compartment osteoarthritis, but the active range of motion(ROM) in HTO group is better than UKA group.
