“…Among the altered gait parameters, maximal and average paw print areas in LIPUS1-2 + 4-5 groups, but not LIPUS 0 group, had either reached baseline or was recovered Zhou et al [40] Divided 18 adult rabbits into a sham operated, an operated untreated group, and an operation with LIPUS therapy delivered daily on day 4 after cartilage surgery Compared to the operation alone, the severity of cartilage injury was decreased in the LIPUS group. [25] Normal and osteoarthritis chondrocytes were exposed to LIPUS, and mRNA and protein expression of cartilage, metalloproteinases and integrin-FAK-PI3K/ Akt signal pathway-related genes were examined using standardized procedures…”

Low intensity pulsed ultrasound [LIPUS], a physical modality that has demonstrated utility in bone healing contexts including non union fracture situations has been proposed to also impact articular cartilage chondrocyte cell metabolism in a favorable way. This current review focuses on two questions: a) whether LIPUS produces any clinically significant impact on chondrocyte structure or function; b) whether the impacts observed support a role for LIPUS in efforts to foster cartilage regeneration and healing applications. Drawn from the English language literature published over the last 35 years, the majority of the available basic or preclinical studies presently reviewed demonstrate LIPUS applications to consistently yield favorable cartilage chondrogenic responses, regardless of substrate, and to be worthy of further exploration in the clinical realm for promoting much sought

“…15 Animal experiments have confirmed that low-intensity pulsed ultrasound has a repair effect on condylar bone defects. 36 Previous studies on physical therapy for patients with TMDs have shown that posture training for patients, including head and neck posture improvement and neck training, can effectively improve the maximum painless mouth opening of patients and improve their activities of daily living. 37,38 Neck and mandibular movement training can be used alone or in combination with other treatments for arthrogenic TMDs, including reducible or irreducible anterior disk displacement.…”

Background:The effectiveness of platelet-rich plasma (PRP) injection combined with physical therapy for the treatment of temporomandibular joint osteoarthritis (TMJ-OA) has not been studied. Objectives:To assess the effectiveness of PRP injection combined with individualised comprehensive physical therapy for the treatment of TMJ-OA.Methods: This prospective cohort study included 40 patients with TMJ-OA who received PRP injection or PRP injection combined with individualised comprehensive physical therapy. Pain intensity, maximum mouth opening, temporomandibular joint sounds, and the Jaw Functional Limitation Scale (JFLS) scores and imaging findings were compared before treatment and during follow-up. Results:The pain intensity, maximum mouth opening, and temporomandibular joint sounds of the two groups significantly improved with an increase in treatment time (p < .05). The pain improvement in the combined treatment group was greater than that in the PRP injection group at 3 and 6 months (p < .05). The improvement of mouth opening was better in the combined treatment group, whereas the improvement of joint sounds was better in the PRP injection group. The improvement in JFLS scores in the combined treatment group was greater than that in the PRP injection group at 6 months (p < .05). The imaging improvement rates of the two groups were similar.Conclusions: Platelet-rich plasma injection can significantly improve pain, mouth opening, abnormal joint sound, and mandibular function in patients with TMJ-OA and has good repair effect on condylar bone defects. PRP injection combined with individualised comprehensive physical therapy can effectively control the mediumand long-term pain of patients.

Artificial hemiarthroplasty is one of the effective methods for the treatment of hip joint diseases, but the wear failure of the interface between the hemi hip joint material and articular cartilage restricts the life of the prosthesis. Therefore, it is important to explore the damage mechanism between the interfaces to prolong the life of the prosthesis and improve the life quality of the prosthesis replacement. In this paper, the creep and bio-tribological properties of cartilage against PEEK, CoCrMo alloy, and ceramic were studied, and the tribological differences between “hard–soft” and “soft–soft” contact were analyzed based on biomorphology. The results showed that with the increase of time in vitro, the thickness of the cartilage membrane decreased, the surface damage was aggravated, and the anti-creep ability of cartilage was weakened. Second, the creep resistance of the soft–soft contact pair was better than that of the hard–soft contact pair. Also, the greater the load and the longer the wear time, the more serious the cartilage damage. Among the three friction pairs, the cartilage in PEEK/articular cartilage was the least damaged, followed by CoCrMo alloy/articular cartilage, and the most damage was found in ceramic/articular, indicating that the soft–soft friction pair inflicted the least damage to the cartilage.
