The knee joint is one of the largest joints in the human body, and it bears the important function of supporting body weight and realizing lower limb movement. However, due to factors such as aging, sports injuries, and obesity, the incidence of knee joint diseases has increased year by year, seriously affecting the quality of life of patients. Ultrasound therapy, as a non-invasive physical therapy, has received widespread attention in the treatment of knee joint diseases in recent years. This study aims to explore the effect of ultrasound therapy in knee joint treatment, in order to provide new treatment ideas and methods for clinical practice.
Theoretical basis and literature review
Ultrasound therapy uses the physical properties of ultrasound to act on human tissues to produce a series of biological effects, thereby achieving the purpose of treatment. Its theoretical basis mainly includes thermal effect, mechanical effect and cavitation effect. The thermal effect increases the temperature of local tissues through the energy deposition of ultrasound in human tissues, thereby promoting blood circulation and accelerating the dissipation of inflammation; the mechanical effect promotes the change of cell membrane permeability through the vibration of ultrasound, accelerates material exchange, and is conducive to tissue repair; the cavitation effect refers to the vibration, expansion and rupture of tiny bubbles in tissue fluid under the action of ultrasound, generating microjets and shock waves, which produce tiny massage effects on tissues and help improve local microcirculation.
Predecessors have achieved remarkable results in the treatment of knee joint diseases with ultrasound therapy. For example, studies have shown that ultrasound therapy can significantly reduce the pain level of patients with knee osteoarthritis and improve joint function. However, there are still some gaps or unresolved issues in current research. For example, the optimal treatment parameters of ultrasound therapy (such as frequency, intensity, treatment time, etc.) have not yet been unified, and there is no unified standard for the treatment of different diseases. In addition, the long-term efficacy and safety of ultrasound therapy still need to be further verified. Therefore, this study aims to further explore the effect of ultrasound therapy in knee joint treatment through more in-depth and systematic research, and provide more accurate treatment plans for clinical practice.
Research design and methods
This study adopted a randomized controlled trial design and randomly divided patients with knee joint diseases who met the inclusion criteria into two groups: an ultrasound treatment group and a control group. The ultrasound treatment group was treated with ultrasound therapy once a day for 20 minutes each time, and a course of treatment lasted for 4 weeks. The control group received conventional physical therapy or drug treatment.
The sources of the research data were mainly the patients' clinical manifestations, imaging examination results and laboratory test data. The patients' pain level was assessed by the visual analog scale (VAS), and the patients' joint function was assessed by the knee joint function score (KSS). At the same time, the treatment process and adverse reactions of the two groups of patients were recorded. The data collection process strictly followed ethical principles to ensure that the privacy and rights of patients were protected.
Research results and analysis
After one course of treatment, the pain level of the patients in the ultrasound treatment group was significantly reduced, and the knee joint function was significantly improved, which was significantly different from the control group (P<0.05). Specifically, the VAS score of the patients in the ultrasound treatment group decreased by an average of about 30%, and the KSS score increased by an average of about 20 points. In addition, the incidence of adverse reactions in the ultrasound treatment group was low, and most of them were mild discomfort, which did not affect the continuation of treatment.
After an in-depth analysis of the research results, this study found that ultrasound therapy has significant therapeutic effects in the treatment of knee joints. Its mechanism of action may be related to the thermal effect, mechanical effect and cavitation effect generated by ultrasound. The thermal effect promotes local blood circulation, accelerates the dissipation of inflammation and relieves pain; the mechanical effect promotes the change of cell membrane permeability, accelerates material exchange, and is conducive to tissue repair; the cavitation effect produces micro-massage effects on tissues by generating microjets and shock waves, which helps to improve local microcirculation. These mechanisms work together to achieve significant therapeutic effects of ultrasound therapy in the treatment of knee joints.
Conclusion and Prospect
The results of this study show that ultrasound therapy has good efficacy and safety in the treatment of knee joints, and can significantly reduce the pain level of patients and improve joint function. This finding provides new treatment ideas and methods for the clinic, which helps to further improve the treatment effect of knee joint diseases. However, this study still has some limitations, such as limited sample size and short treatment time. Future studies can further expand the sample size and extend the treatment time to more comprehensively evaluate the efficacy and safety of ultrasound therapy. In addition, we can also explore the optimal treatment parameters of ultrasound therapy in depth to provide a scientific basis for the formulation of a unified treatment plan. At the same time, we can pay attention to the combined application of ultrasound therapy with other treatment methods in order to achieve better treatment results.
In summary, ultrasound therapy has shown significant efficacy and safety in knee joint treatment and has broad application prospects. With the continuous advancement of medical technology and in-depth research, it is believed that ultrasound therapy will be more widely used and promoted in the future, bringing good news to more patients with knee joint diseases.
