Creating Perforations in the Sclerotic Region of the Proximal Tibia During Total Knee Arthroplasty to Enhance Prosthesis Stability

Orthopaedic Surgery, Volume 17, Issue 5, Page 1397-1405, May 2025.
Abnormal stress in the proximal tibia modifies the bone mineral density distribution pattern, and drilling in the sclerotic region during total knee arthroplasty is correlated with enhanced prosthesis stability. ABSTRACT Objective In patients with varus deformity of the knee, the redistribution of the subchondral bone mineral density (BMD) of the tibia

Routine circumferential patellar denervation during total knee arthroplasty did not consistently eliminate neural structures at the lateral patellar border: A prospective randomised controlled trial with histological outcomes

Journal of Experimental Orthopaedics, Volume 13, Issue 3, July 2026.
Abstract Purpose Circumferential patellar denervation is widely performed during total knee arthroplasty under the assumption that electrocautery ablates nociceptive neural structures at the lateral patellar border. However, the microscopic effect of this procedure on neural substrates remains poorly defined.

Subchondral bone expansion in advanced knee osteoarthritis: Relation with radiographic severity and role in surgical decision-making

Osteoarthritis and Cartilage Open
Background: Joint space width (JSW) is a traditional imaging marker for knee osteoarthritis (OA) severity, but it lacks sensitivity in advanced cases.

Surgical Treatment of Insufficiency Fractures of the Knee

Arthroscopy Techniques, 2019
Bone marrow lesions (BMLs) in the knee represent focal edema caused by subchondral bone attrition and microfractures to the trabecular bone. These lesions are poor prognostic indicators for several orthopaedic procedures but also have been associated ...

Posterior tibial slope varies across functional tibial phenotypes but not CPAK categories: A radiographic analysis from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 7, Page 2462-2468, July 2026.
Abstract Purpose The relationship between the coronal and sagittal planes of the knee remains largely unexplored. The aim of this study was to evaluate the correlation between Posterior Tibial Slope (PTS), Hirschmann's functional tibial phenotypes, CPAK categories, and their defining parameters, hypothesising that coronal and sagittal tibial parameters

Imaging Review of Different Subchondral Insufficiency Fractures

Subchondral fractures are a common cause of joint pain that may ultimately lead to articular collapse and the need for arthroplasty. This type of fracture has been reported at multiple joints throughout the body.

Unrestricted kinematic alignment on the sagittal plane: Posterior tibial slope and combined flexion do not have boundaries to respect in terms of short‐term clinical outcomes and safety

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 7, Page 2469-2478, July 2026.
Abstract Purpose Personalized alignment in total knee arthroplasty (TKA) is gaining traction as a surgical philosophy. True personalization, however, must encompass not only the coronal plane but also the sagittal and axial planes. This study evaluates influence of the Tibial Slope (PTS) and combined flexion (CF) on outcomes in TKA performed using ...
