Fracture of the Femoral Component Caused by Insufficient Crimping after Modern Unicompartmental Knee Arthroplasty

Case Reports in Orthopedics, 2019
Fracture of a femoral component after modern unicompartmental knee arthroplasty is very rare. Although this is not the first case on this subject, no study has reported insufficient crimping as the cause of femoral component loosening that led to ...

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.

Lower synovial leucocyte count and polymorphonuclear percentage reliably differentiate periprosthetic joint infection after unicompartmental knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 4, Page 1310-1317, April 2026.
Abstract Purpose This study aimed to determine diagnostic thresholds for synovial fluid leucocyte count and polymorphonuclear (PMN) percentage to identify the diagnosis periprosthetic joint infection (PJI) in patients with failed unicompartmental knee arthroplasties (UKAs).

Reduced spinopelvic mobility does not correlate with knee flexion deformity in patients undergoing total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 4, Page 1346-1353, April 2026.
Abstract Purpose The aim of this study was to evaluate the impact of reduced spinopelvic mobility (SM) on knee flexion deformity (KFD) in patients undergoing total knee arthroplasty (TKA). Methods A retrospective analysis on 213 patients (271 knees) undergoing robotic‐assisted primary TKA was conducted.
