This research by SORI surgeons Dr Myles Coolican and former Fellow Dr Ignacio Fernández was published in the Journal of ISAKOS in October 2025. Read HERE. Knee osteoarthritis can lead to pain, stiffness, and a decline in daily function. For younger patients with misaligned knees, a high tibial osteotomy (HTO) offers a joint-preserving option to relieve pressure on the affected compartment and delay the need for a total knee replacement. However, arthritis can progress over time, and some...

“Equivalent accuracy of image-based and imageless robotic platforms in achieving planned femoral rotation in primary total knee arthroplasty: A CT-based study” was published in the Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) Journal in July 2026. As robotic-assisted total knee arthroplasty (TKA) becomes increasingly established in contemporary practice, an important question remains: does the type of robotic platform - image-based or imageless - influence the accuracy of femoral...

A new MRI-based study has provided further evidence that excessive joint line obliquity (JLO) following medial opening wedge high tibial osteotomy (MOWHTO) may have unintended consequences for the lateral compartment of the knee. Using advanced quantitative MRI analysis, researchers investigated the relationship between postoperative JLO and cartilage health, highlighting an important consideration for surgical planning and correction targets. Aim The study aimed to determine whether...
