Development of a Passive Knee Motion Simulator to Evaluate Deep Knee Flexion of Total Knee Prosthesis

Journal of Biomechanical Science and Engineering, 2009
To evaluate motions and joint reaction forces of the total knee prosthesis during deep knee flexion such as kneeling and sitting straight, a simulator that reproduces the passive motion of the knee has been developed. The main feature of the simulator is

Adolescence risk factors for meniscus and ligamentous knee injuries in adulthood: A longitudinal study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Our aim is to investigate the influence of adolescent health‐related behaviours on the occurrence of meniscus and ligament injuries in a large cohort of Finnish adolescents with an average 27‐year follow‐up. Methods The baseline data were surveys conducted biannually from 1981 to 1997, and these were individually linked to outcomes, as

Nontraumatic Fracture of the Femoral Condylar Prosthesis in a Total Knee Arthroplasty Leading to Mechanical Failure

Case Reports in Orthopedics, 2014
This paper reports a case of fatigue fracture of the femoral component in a cruciate-retaining cemented total knee arthroplasty (TKA). A 64-year-old man had undergone a primary TKA for osteoarthritis 10 years previously at another institution using the ...

The unstable knee prosthesis

Revista Española de Cirugía Ortopédica y Traumatología (English Edition), 2009
Abstract Prosthetic instability is the third most frequent cause for the failure of total knee replacement (TKR), which leads to between 10% and 22% of surgical revisions. In addition to individual factors such as previous instabilities or deformities, an associated neuromuscular condition, rheumatoid arthritis or obesity, the main causes for ...

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

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
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).

A novel knee implant for total knee arthroplasty meets expectations at 10 years. First long‐term follow‐up report of clinical outcomes and survivorship

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Achieving a “forgotten knee” after total knee arthroplasty (TKA) remains a primary goal in modern knee replacement surgery. Anatomic implant designs aim to replicate native knee anatomy and kinematics, potentially improving patient satisfaction and functional outcomes.

Comparable outcomes and early revision rates between restricted and unrestricted functional knee positioning in robotic‐assisted total knee arthroplasty for varus deformities ≥10°

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Functional knee positioning (FKPos) in total knee arthroplasty (TKA) optimises outcomes by balancing individual anatomical and soft tissue characteristics. Managing marked varus deformity presents challenges in achieving balance when tibial alignment is restricted to 3° of varus, necessitating either medial soft tissue release or ...

Step‐by‐step insight into gait analysis: A narrative review unlocking knee biomechanics

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Gait analysis offers a powerful tool for clinical and orthopaedic decision‐making. By quantifying spatiotemporal, kinematic and kinetic parameters during walking, it provides a dynamic window into joint function that static imaging cannot capture.

Patient reported outcomes improve following lower limb prosthesis and socket and replacement

Journal of Patient-Reported Outcomes
Background Prosthetic sockets are fundamental in stabilizing the residual limb and providing a secure attachment for the prosthesis, therefore aiding in achieving a more natural and efficient walking motion.
