8 results about "Ankylosis" patented technology

Ankylosis is a stiffness of a joint due to abnormal adhesion and rigidity of the bones of the joint, which may be the result of injury or disease. The rigidity may be complete or partial and may be due to inflammation of the tendinous or muscular structures outside the joint or of the tissues of the joint itself.

Multi-component synovitis therapeutic composition based on repairing cartilage tissue and use thereof

PCT designated stageWO2026115524A2Organic active ingredientsDimethyl SulphoneCartilage repair
The present invention discloses a multi-component synovitis therapeutic composition based on cartilage tissue repair and a use thereof, relating to the technical field of biomedicine. The composition comprises glucosamine hydrochloride, chondroitin sulfate, dimethyl sulfone, and graded molecular weight sodium hyaluronate. By compounding these components in precise parts by weight, the present invention constructs a gradient sustained-release and targeted delivery system for synovitis lesions. Dimethyl sulfone specifically inhibits hyaluronidase activity in the inflamed joint cavity, significantly reducing sodium hyaluronate degradation and prolonging the retention time of each active ingredient at the lesion site. High molecular weight sodium hyaluronate rapidly forms a lubricating protective film to achieve immediate analgesia and relieve ankylosis, while medium- and low-molecular-weight sodium hyaluronate penetrates the synovial barrier and carries cartilage repair components to the cartilage defect area, thereby achieving synergistic enhancement and comprehensively improving synovitis treatment efficacy.

Research method based on principle of action of low-intensity focused ultrasound on joint stiffness

PendingCN119656497AHelps reveal molecular mechanismsreduce fibrosisUltrasound therapyMicrobiological testing/measurementDiseaseSMAD
The invention discloses a research method based on the action principle of low-intensity focused ultrasound on joint stiffness, and relates to the technical field of joint stiffness treatment. Safe and effective treatment measures are found for patients with ankylosis; comprising the following steps: experimental animals are grouped and modeled, male rats in specific age groups and weight ranges are selected and randomly divided into a normal group, a stiffness group and an ultrasonic stiffness group, and a joint stiffness model is established; and performing LIFU treatment, namely performing low-intensity focused ultrasound treatment on the rats of the ultrasonic stiffness group. Through qRT-PCR (quantitative reverse transcription-polymerase chain reaction), Western blotting, cellular immunofluorescence and other technical means, the research finds that the LIFU can improve the joint stiffness condition by inhibiting the activation of fibroblasts and the expression of a TGF-beta / Smad signal channel, so that not only is the molecular mechanism of the LIFU for treating the joint stiffness disclosed, but also an important index is provided for evaluating the treatment effect and predicting the disease progress.
