BACKGROUND Significant correlation has been previously demonstrated between radiographic and clinical diagnoses of knee osteoarthritis (OA); however, the specific findings on clinical examination that relate best to a radiographic diagnosis have not been fully elicited. AIMS We aimed to explore the relationship between clinical symptoms and physical findings with radiographic diagnoses of tib...

OBJECTIVES To compare the prevalence of osteoarthritis (OA) of the hip, tibiofemoral and patellofemoral joints in a skeletal population. METHODS A total of 785 adult English skeletons (695 Saxon or Mediaeval origin) were examined for OA using established criteria. RESULTS Twenty nine skeletons had hip OA, compared with 14 with patellofemoral joint OA, and only four tibiofemoral joint OA. ...

PURPOSE To evaluate the influence of postoperative tibiofemoral alignment on the clinical results and failure in patients who underwent unicompartmental knee athroplasty (UKA). MATERIALS AND METHODS We reviewed 246 cases of medial UKA which were followed up for at least 5 years after the operation. The clinical results were compared between 5 groups classified according to the tibiofemoral an...

Muscles induce large forces in the tibiofemoral joint during walking and thereby influence the health of tissues like articular cartilage and menisci. It is possible to walk with a wide variety of muscle coordination patterns, but the effect of varied muscle coordination on tibiofemoral contact forces remains unclear. The goal of this study was to determine the effect of varied muscle coordinat...

BACKGROUND Coronal tibiofemoral (CTF) subluxation is a common finding in knee osteoarthritis (OA) which can be related to poor pain scores and tibial spine impingement. In this study we describe a new method for measuring CTF subluxation and present validation of the method using cadaveric knees. METHODS A prototype software code based on the ICP mathematical algorithm was developed to measur...

congenital anterior tibiofemoral subluxation is an extremely rare disorder. all reported cases accompanied by other abnormalities and syndromes. a 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. deformities were due to tightness of the iliotibial band and biceps femuris muscles a...

BACKGROUND This study was conducted to find out the age when tibiofemoral angle starts to be in valgus and reaches maximum angle. The differences of the angles between genders were also studied. METHODOLOGY This cross sectional study on tibiofemoral angle was conducted among 160 normal healthy children using clinical measurement method. The children between 2 18 months to 6 years old were ass...

Estimating tibiofemoral joint contact forces is important for understanding the initiation and progression of knee osteoarthritis. However, tibiofemoral contact force predictions are influenced by many factors including muscle forces and anatomical representations of the knee joint. This study aimed to investigate the influence of subject-specific geometry and knee joint kinematics on the predi...

OBJECTIVES To evaluate the frequency of patellofemoral osteoarthritis and its relevance to symptoms and function in a meniscectomy population. METHODS 317 patients with no cruciate ligament injury were evaluated (mean (SD) age, 54 (11) years). They had undergone meniscal resection 15 to 22 years earlier (follow up rate 70%). Standing tibiofemoral and skyline patellofemoral radiographs were gr...

BACKGROUND Our current understanding of tibiofemoral kinematics in the anterior cruciate ligament (ACL)-deficient knee is very limited. Using vertical open-access MRI, it is possible to accurately analyze tibiofemoral motion in patients with isolated rupture of the ACL. STUDY Prospective cohort study. PURPOSE To assess if ACL rupture alters normal knee weightbearing kinematics. METHODS Ti...
