Increased Joint Line Obliquity Linked to Lateral Cartilage Degeneration After MOWHTO
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

What’s new - improving patellar positioning in patello femoral arthroplasty with robotics
Patello‑femoral arthroplasty (PFA) - a surgical option for people with isolated arthritis of the patella and trochlea - can relieve pain and restore function when disease affects only the front part of the knee. But surgeons have long struggled with two key challenges - ensuring the trochlear implant is seated such that it accurately resurfaces the worn areas , and that the natural patellar tracking is restored. The new 2025 study conducted by Dr Jobe Shatrov and colleagues d

Patient-reported outcomes are comparable between imageless robotic-assisted and computer-navigated total knee arthroplasty
A recent retrospective cohort study, conducted by Jacob O’Brien, David Parker, Pradyumna Raval, Harbeer Ahedi, and Myles Coolican , and recently published in the latest edition of the KSSTA Journal , directly compared patient-reported outcomes (PROMs) following imageless robotic-assisted total knee arthroplasty (RA-TKA) versus computer-navigated TKA (CN-TKA), addressing a key question as RA-TKA adoption continues to grow. https://esskajournals.onlinelibrary.wiley.com/doi/10.1
