Posterior tibial slope measurement on lateral radiographs shows increased variability, reduced repeatability and risk of misclassification in osteoarthritic versus nonosteoarthritic knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The primary aim was to compare the variability and repeatability of medial posterior tibial slope (MPTS) measurements on lateral knee radiographs between osteoarthritic (OA) and non‐OA knees, and the secondary aim was to assess their implications for clinical classification.

Metatarsophalangeal Joint Reconstruction Using Talar Osteochondral Allograft following a Failed Dorsal Cheilectomy

Case Reports in Orthopedics, 2022
Dorsal cheilectomy is often used as a first-line surgical treatment for hallux rigidus; however, revision surgery is needed in nearly 9% of cases. One option for revision surgery is interpositional arthroplasty, which is designed to preserve joint motion

Mechanical axis correction after total knee arthroplasty alters ankle alignment but does not affect ankle function

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Total knee arthroplasty (TKA) restores knee function, but correction of coronal plane deformities may alter the biomechanics of adjacent joints. This study aimed to determine whether changes in knee alignment after TKA have clinical or radiological effects on the ankle.

Subchondral Bone Relative Area and Density in Human Osteoarthritic Femoral Heads Assessed with Micro-CT before and after Mechanical Embedding of the Innovative Multi-Spiked Connecting Scaffold for Resurfacing THA Endoprostheses: A Pilot Study

, 2021
The multi-spiked connecting scaffold (MSC-Scaffold) prototype is the essential innovation in the fixation of components of resurfacing total hip arthroplasty (THRA) endoprostheses in the subchondral trabecular bone.

Alterations of the subchondral bone in osteochondral repair – translational data and clinical evidence [PDF]

European Cells & Materials, 2013
Alterations of the subchondral bone are pathological features associated with spontaneous osteochondral repair following an acute injury and with articular cartilage repair procedures.

Knee osteoarthritis patients with more subchondral cysts have altered tibial subchondral bone mineral density

BMC Musculoskeletal Disorders, 2019
Background Subchondral bone cysts are a widely observed, but poorly understood, feature in patients with knee osteoarthritis (OA). Clinical quantitative computed tomography (QCT) has the potential to characterize cysts in vivo but it is unclear which ...

The effect of distance between holes on the structural stability of subchondral bone in microfracture surgery: a finite element model study

BMC Musculoskeletal Disorders, 2020
Background Microfracture is a surgical technique that involves creating multiple holes of 3–4 mm depth in the subchondral bone to recruit stem cells in the bone marrow to the lesion, inducing fibrocartilage repair and knee cartilage regeneration ...

Can Knee Arthroscopy Be Considered Entirely Safe for Patients Over 50 Years Old With no Risk of Osteonecrosis? Case Series and Literature Review on Post‐Artrhoscopy Osteonecrosis of the Knee (PAONK)

Orthopaedic Surgery, Volume 17, Issue 5, Page 1378-1388, May 2025.
Post‐arthroscopy osteonecrosis is a rare complication occurring in 0.82% of cases, primarily affecting patients over 50 with degenerative meniscal tears. Early detection through MRI and conservative treatment, including bisphosphonates and weight‐bearing avoidance, proved effective in most cases, while some required surgical intervention.

Clinical Outcomes of Medial Meniscus Posterior Root Tears

Orthopaedic Journal of Sports Medicine, 2016
Objectives: Medial meniscus posterior root tears (MMPRTs) present a unique challenge for both patients and surgeons as these tears have shown to be biomechanically equivalent to complete meniscectomy. However, little is known about the natural history of

Is subchondral cyst an indicator for osteoblast dysfunction in knee osteoarthritis? [PDF]

, 2014
INTRODUCTION: Subchondral bone cyst (SBC) is a key radiological feature in advanced OA. The presence of SBC was reported in a relation to the risk of cartilage loss and total knee arthroplasty (TKA). Whilst the link between SBCs and bone dysmetabolism in
