Changes of articular cartilage after immobilization in a rat knee contracture model
The objective was to determine the changes of articular cartilage of the knee joint during immobilization in a rat model. The knee joints of adult male rats were immobilized at 150° of flexion using
Chondrogenic and Fibrotic Process in the Ligamentum Flavum of Patients With Lumbar Spinal Canal Stenosis
TLDR
Synthesis of the collagenous fibers and degradation of the elastic and collagenous fiber are both accelerated in the ligamentum flavum of patient with LSCS, which may be the reason for hypertrophy of the tissue.
Expression of transforming growth factor-β1 and connective tissue growth factor in the capsule in a rat immobilized knee model
TLDR
The capsule has a potency to produce TGF-β1 and CTGF after immobilization and may play a role in causing and maintaining capsular fibrosis in collaboration with TGF -β1.
Imaging features of foreign body granuloma in the lower extremities mimicking a soft tissue neoplasm
TLDR
Three patients of foreign body granulomas in the lower extremities with emphasis placed on their unique clinical and radiological features are reported, finding that the peripheral areas of the lesion were strongly enhanced after gadolinium injection.

TLDR
Results indicate that atrophic changes through decreased mechanical stress in the non-contact area were reversible, but loss of chondrocytes and hypertrophy in the contact and transitional areas through increased mechanical stress by rigid immobilization were irreversible after remobilization.
Joint Immobilization Induced Hypoxic and Inflammatory Conditions in Rat Knee Joints
TLDR
The data indicated that joint immobilization induced hypoxic and inflammatory conditions in the joint capsule, which might be an initiating factor for joint contracture.
Reliability and validity of the Western Ontario Shoulder Instability Index (WOSI) in the Japanese population
TLDR
The WOSI Japanese questionnaire is a reliable self-assessment tool that is comparable with the original English version and should be used when evaluating patients with shoulder instability in the Japanese population.
Expression of Collagen Types I and II on Articular Cartilage in a Rat Knee Contracture Model
The purpose of our study was to clarify the expression patterns of collagen types I and II on articular cartilage after immobilization in a rat knee contracture model in 3 specific areas (noncontact
Expression patterns of collagen types I and III in the capsule of a rat knee contracture model
TLDR
The expression of mRNA and protein levels of collagen types I and III were not increased after immobilization, which indicated that accumulation of the two types of collagen was not the etiology of joint contracture.
