Background: Patellofemoral pain syndrome is a prevalent sports injury that affects athletes both in their daily lives and during training. This condition causes pain in the area where the kneecap and thigh bone meet, and it can be quite debilitating. Whether an athlete is simply going about their day or pushing themselves to the limit during a workout, patellofemoral pain can be a significant hindrance. Purpose: The purpose of this study is to investigate the impact of combining Instrument-Assisted Soft Tissue Mobilization (IASTM) treatment with blood flow restriction training on individuals with patellofemoral pain. Specifically, the study will assess improvements in pain levels, functional ability, strength, and joint mobility resulting from this treatment approach. Methods: Twenty-six patients diagnosed with patellofemoral pain were selected as observation subjects and randomly divided into two groups: the IASTM combined with blood flow restriction training treatment group (n=13) and the IASTM treatment group alone (n=13). The treatment period was 4 weeks. In this study, we conducted a comparison and analysis of the knee's visual analogue pain scale (VAS), Lysholm score, and a modified version of the Thomas test (MTT) at three different time points.In this subject paper, we compared and analyzed the VAS score of the knee, Lysholm score of the knee, and MTT at three different time points - before treatment, immediately after the first treatment, and after four weeks of treatment. Additionally, we recorded data using a maximum isometric muscle strength testing system for the lower extremity extensors four weeks before and after treatment. Results: In the intra-group comparison of Lysholm score, after the first treatment and 4 weeks of treatment, the scores of the two groups were significantly different from those before treatment (P<0.05), and the VAS scores after the first treatment and 4 weeks of treatment were significantly different from those before treatment (P<0.05), and the pain was significantly improved. After 4 weeks of treatment, the strength of the extensor muscle of the lower extremity was significantly improved (P<0.001), but there was no significant change in the strength test between groups (P>0.05). After MTT test, there were significant changes in the three joint angles before and after treatment (P>0.05). Conclusion: The combination of IASTM treatment and blood flow restriction has been shown to significantly reduce pain and improve periprosthetic soft tissue flexibility. Additionally, IASTM treatment alone was found to be more effective in improving knee pain and muscle flexibility, ultimately leading to increased knee strength in a pain-free state.In terms of the overall treatment outcome, it was found that the combined treatment was significantly more effective than the adjuvant soft tissue release treatment alone.

Purpose To analyse the research conducted in recent years on conservative treatment modalities for different diseases of the knee joint, to provide a correct orientation for hip-knee-ankle lower limb force line correction methods, and to provide a theoretical basis for the creation of a good mechanical environment for the knee joint, a reasonable joint space, and a neutral movement trajectory that allows for sustainable and safe treatment. Methods Information was retrieved from the electronic databases PubMed and cnki to select studies using physiotherapy as an intervention for knee related disorders between 2018–2022. Ultimately, 19 randomised controlled trial studies were included, involving a total of 1073 clinical studies. Results In the ankle area, the strength line of the lower limb can be improved by wearing custom-made insoles, gait correction training and functional and strength training of the ankle. In the knee joint, the strength and stretching of the quadriceps muscles can be strengthened and the line of force of the lower limb stabilised through different training modalities (centripetal and centrifugal training, electrical nerve stimulation, blood flow restriction training). At the hip joint the control of the lower limb can be increased by increasing the strength of the hip joint in external rotation and abduction and by improving the pain at the joint using acupuncture therapy and physiotherapy with tui na. Conclusions By physically adjusting the hip-knee-ankle joint, it is possible to treat knee-related disorders by progressively correcting the aberrant lower limb force lines and improving the knee-related disorders' symptoms.
