Myxiod degeneration in posterior meniscu

I have little knee pain after doing squat exercise. Earlier I only feel little knee pain while doing squat. But on 1st september 2023 morning after doing squat (without weight) I felt knee stiffness, dump pain and knee weakness. After this incident I left squat took little rest and knee issue feels improved I was able to perform all activity. But on 2nd november I again felt little knee pain as I have walked on uneven surfaces. Recently I have done mri and it says following: 1) grade 2 myxoid degeneration involving posterior horn of the medial meniscus 2) fluid collection adjacent to the posterior horn of medial meniscus- ?paramedical cyst/ distended medial gastrocnemius semimembranosus bursa. Following is the symptoms: 1) dump localised knee pain at posterior meniscus 2) click sound 3) knee weakness and very very little stiffness. 1) I can do knee straightening/ bending.. but feel little pain while pivoting and walking for long time. Please suggest how to treat this condition
