Summary: This study evaluated the bone union and clinical outcomes of using a novel wedge-shaped cancellous allograft to fill the osteotomy gap after MOWHTO. The results showed that this method provided good bone healing and improved clinical scores.

Summary: This study compared the clinical and radiological outcomes of MOWHTO with different types of graft (autograft, allograft, or no graft) at 1 year postoperatively. The results showed that autografts resulted in superior bone union outcomes compared to allografts and no graft, suggesting that routine use of allografts should not be recommended.

Summary: This study investigated the effects of tibial tubercle fracture on clinical outcomes and bony union in medial opening wedge high tibial osteotomy with distal tibial tubercle osteotomy (DTO), as well as the anatomical risk factors for tibial tubercle fracture. The findings suggest that tibial tubercle fracture did not affect clinical outcomes and bony union, despite its relatively high occurrence rate. One anatomical risk factor for tibial tubercle fracture was a lower tibial tubercle position.

Summary: This study used CT-osteabsorpitometry to investigate the effects of OWHTO and CWHTO on the distribution patterns of subchondral bone density across the ankle joint. The results showed that after OWHTO, the distribution pattern shifted medially, while after CWHTO, the distribution shifted laterally. Surgeons should be cautious of potential postoperative progression of ankle osteoarthritis due to the shift in stress distribution.

Summary: This study used finite element analysis to investigate the effects of hinge location and apical drill holes on cortical bone in high tibial osteotomy. The results showed that larger intact hinges were associated with higher cortical bone stress and strain, while smaller apical drill holes reduced these stresses and strains, leading to improved control and reduced force required for the osteotomy.

Summary: This study investigated the relationship between postoperative alignment using whole-leg standing radiographs and clinical outcomes after open wedge high tibial osteotomy (OWHTO). The study found that overcorrection was associated with inferior clinical outcomes and should be avoided for patient satisfaction. Knees with undercorrected alignment showed similar clinical results to those with appropriate correction.

Summary: This study established and validated a novel evaluation method using digital tomosynthesis to quantify bone formation after high tibial osteotomy. The gap filling value (GFV) increased over time and was moderately correlated with the modified van Hemert's score, plateauing at 6 months postoperatively. The GFVs obtained using digital tomosynthesis can accurately and reproducibly assess postoperative bone formation in the gap after osteotomy.

Summary: This study evaluated the effects of anterior tibial closing wedge osteotomies on coronal plane alignment and identified predictive factors for a change in medial proximal tibial angle (MPTA). The results showed that this surgery resulted in a significant decrease in MPTA, which was dependent on the preoperative MPTA and the wedge height.

Summary: This study compared the clinical outcomes and radiographic parameters of distal tibial tubercle high tibial osteotomy (DTTHTO) and open wedge high tibial osteotomy (OWHTO) in patients with varus knee osteoarthritis. The results showed that patients who underwent DTTHTO had better postoperative alignment and lower postoperative pain scores. Additionally, DTTHTO had shorter operation time and less surgical trauma.

Summary: This study compared the accuracy of applied correction angle between hybrid lateral closed wedge high tibial osteotomy (hybrid HTO) and medial open wedge high tibial osteotomy (OWHTO), and verified previous reports on hybrid HTO by matching correction angle between groups. The results showed that hybrid HTO had similar accuracy in angular correction compared to correction angle-matched OWHTO. Additionally, hybrid HTO demonstrated a reduction in posterior tibial slope, tibial shortening, maintained patellar height relative to the proximal tibia, and faster osteotomy site union compared to OWHTO.

Summary: This study identified smoking, diabetes mellitus, and old age as potential risk factors for surgical site infection after MOWHTO, highlighting the importance of patient selection and careful postoperative care, especially for smokers.

Summary: This meta-analysis evaluated the effectiveness of bone substitute materials (BSM) in opening wedge high tibial osteotomy (OWHTO) for knee osteoarthritis. The findings suggest that BSM combined with locking plate techniques is a safe and efficient alternative option for osteotomy gaps larger than 10 mm. However, due to the heterogeneity and low quality of the included studies, the results should be interpreted with caution.

Summary: This study demonstrates that the use of patient-specific instruments (PSI) in OW-HTO allows for accurate correction and shorter operation time compared to conventional osteotomies. Additionally, the number of radiological exposures is reduced in PSI-assisted procedures.

Summary: This study aimed to investigate the rate of cartilage regeneration following an open-wedge high tibial osteotomy (HTO) without any cartilage regeneration procedures, using second-look arthroscopy. A total of 65 patients who underwent open-wedge HTO between July 2014 and March 2019 were included in the study. The hip-knee-ankle (HKA) angle and tibial slope were measured pre- and postoperatively (second-look arthroscopy). The articular cartilage of the medial femoral condyle (MFC) and medial tibial plateau (MTP) were evaluated using the International Cartilage Repair Society (ICRS) grading system. After 26.5 months, second-look arthroscopy was performed to assess the cartilage status of the MFC and MTP after plate removal. Approximately 44.6% and 29.2% of patients showed improved cartilage statuses on the MFC and MTP after open-wedge HTO, without any cartilage regeneration procedures, and these regenerations did not influence clinical outcomes.

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.
