Summary: This study aimed to investigate the effects of Medial opening-wedge high tibial osteotomy (MOWHTO) on ankle symptoms and ankle and hindfoot alignments in patients with different severity of ankle osteoarthritis (OA). The study found that ankle pain worsened in patients with severe ankle OA, while patient-reported outcome measures for the knee joint showed no differences between the two groups of patients.

Summary: This study aimed to assess the association between the pelvis-knee-ankle angle (PKA) and knee adduction moment (KAM) following high tibial osteotomy (HTO) and patient-reported outcomes. The results showed that PKA was significantly correlated with KAM peaks in patients with varus knee osteoarthritis after HTO, while hip-knee-ankle angle (HKA) did not show significant correlation.

Summary: Comparing TCVO and OWHTO, TCVO is more effective in treating advanced knee OA with intra-articular deformity, but has limited capacity to correct varus angle. TCVO may be suitable for medial-compartment OA with pre-operative FTA >= 185 degrees.

Summary: This study aims to compare the clinical outcomes between tibia osteotomy with absorbable spacer combined with fibular osteotomy (TPOASI) and opening-wedge high tibial osteotomy (OW-HTO) in the treatment of knee osteoarthritis. The results show that both procedures have similar clinical scores, radiographic results, and complications, but TPOASI has the advantage of avoiding internal fixation removal.

Summary: The study demonstrated that medial opening wedge HTO can improve articular cartilage composition in the medial compartment of the knee without negatively affecting the lateral compartment or patella. Furthermore, there were low associations between radiographic measures and T2 values of cartilage composition.

Summary: This study evaluated the effects of high tibial osteotomy (HTO) on knee osteoarthritis using joint markers in synovial fluid. The results showed significant improvement in knee function and structure after surgery, as well as decreased concentrations of joint biomarkers in synovial fluid, indicating an improvement in disease state.

Summary: This study evaluated the proportion of patients meeting responder criteria after two years of medial opening wedge HTO and investigated predictors of response. The results showed that 78% of patients met the responder criteria at 2 years postsurgery. Older age, higher BMI, and larger postoperative mechanical axis angles were associated with increased odds of achieving responder criteria. When stratified by sex, 78% of male patients and 76% of female patients met the responder criteria.

Summary: Clinical, radiographic, and functional outcomes were significantly improved in both groups after UKA. However, patients who had a previous HTO experienced less improvement in clinical and functional outcomes compared to those without prior HTO.

Summary: This study aimed to investigate the compensation ability of the knee joint inclination after medial opening wedge high tibial osteotomy (MOWHTO). The results showed that the postoperative knee-ankle joint line angle (KAJA) significantly contributed to the knee joint line obliquity (KJLO), and the incidence rate of high-grade KJLO increased when the postoperative KAJA exceeded 9.6 degrees.

Summary: The study compared alignment parameters in patients undergoing HTO for knee OA and non-arthritic controls, finding that patients with knee OA had more femoral varus alignment compared to controls, while tibial morphology was similar. This information is important for pre-operating planning for realignment osteotomy in patients with knee OA and warrants further investigation.

Summary: This study evaluated the impact of high tibial osteotomy (HTO) on balance control in patients with knee osteoarthritis (OA) and varus deformity. The results showed that balance control improved in patients one year after HTO. Furthermore, HTO improved the alignment and function of the affected knee.

Summary: This study evaluated the distribution of subchondral bone density across the proximal tibia in nonarthritic knees and knees of patients with osteoarthritis before and after high tibial osteotomy (HTO). Results showed that HTO shifted the high-density areas of the medial compartment of the proximal tibial articular surface toward the lateral compartment, with an increase in the most lateral region of the medial compartment.

Summary: This study investigated the changes in coronal and sagittal alignment of the knee and ankle joint after HTO. The results showed that HTO can correct varus alignment of the knee and significantly affect the coronal and sagittal alignment of the ankle joint.

Summary: The study observed changes in miRNA and inflammatory mediators before and after high tibial osteotomy (HTO) and investigated the mechanism of HTO in relieving knee osteoarthritis. The results showed that HTO surgery reduced proinflammatory cytokine levels and extracellular matrix proteins, while increasing HA, miR-23a-3p, and miR-30c-5p expression levels. Furthermore, miR-23a-3p and miR-30c-5p upregulation rescued the damaging effect of LPS induction on synoviocytes.

Summary: The study evaluated the clinical efficacy of DTT-HTO using a new patented pi-shaped plate in obese patients with varus knee osteoarthritis. Results showed that DTT-HTO yielded excellent clinical outcomes in obese patients, with no correlation between BMI and postoperative results.

Summary: This study aimed to evaluate if age is associated with the risk of short-term complications after ACL reconstruction. The results showed that older patients had higher fragility index scores, shorter operative times, and lower use of general anesthesia. Older age was an independent risk factor for VTE, while younger age was associated with prolonged surgeries.

Summary: This study aimed to determine the minimal clinically important difference (MCID) and the patient acceptable symptoms state (PASS) threshold for the knee injury and osteoarthritis outcome score (KOOS) pain subscore, KOOS physical short form (PS), and KOOS joint replacement (JR) following medial unicompartmental knee arthroplasty (mUKA). The study identified useful values for the MCID and PASS thresholds at 1 year following medial UKA of KOOS pain, KOOS PS, and KOOS JR scores. These values may be used as targets for surgeons when evaluating PROMS using KOOS to determine whether patients have achieved successful outcomes after their surgical intervention.
