I injured my knee while walking the mountains in California the summer of 2019. I ordered the Knee T Shellz Pad. I didn't know if it would work to repair my damaged muscle, but after reading the information on the website, I believe it would be beneficial to try. I used it for 3 months 3 times a day, and after 3 months the pain and swelling went away. The result was amazing. I would recommend using the Knee T Shellz Pad before ever thinking about surgery.
