Hi, I met with an road accident few years back, as a result my left knee got badly injured and doctors had to perform skin graft on knee. Post operation I developed stiffness in knee. Now I met few doctors who recommended me to go for quadriceps plenty and arthroscopic artholysis for knee bending. However my MRI report reads that I developed Quadriceps muscles atrophy with mild fatty changes. One doctor told me that I should any types of surgery since I have very weak Quadriceps muscles? Does weak Quadriceps would really be problem?
