Bone & Muscle problems

I tore my posterior horn of medial meniscus few days ago (Grade 3). My doctor recommended physiotherapy after clinical inspection. My understanding for doing physiotherapy is making the muscles around the hips, quads, hamstring etc stronger so that there wouldn't be much stress to the torn meniscus. But once we stop doing physiotherapy, won't the muscles become weaker again? As we are not training them and this in turn would cause the pain to come back. Can someone let me know how physiotherapy performs in the long run?

I have had PCL reconstruction surgery on 30th Jan, followed by knee debridement and lavage on 26th Feb due to consistent pain, swelling and mild grade fever. However lab results for PUS culture, Synovial Fluid culture and MTB were negative, ruling out any local infection. CRP and ESR are high at 39 and 36 respectively, rest parameters of blood test are normal .  After 26 Feb, pain was reduced but still it is there. Swelling is there as well. Fever comes and go (99 to 99.5) like 3-4 times in a week. MRI was redone. Result is- Marrow Edema in distal femur and proximal tibia, moderate joint effusion with synovial thickening and bulky patellar tendonitis . rest reported normal. Want to know why I still have pain, swelling on knee cap and mild fever thats keeps on coming. What should I do next. I have stopped taking any antibiotics. Not taking physiotherapy sessions also due to pain and swelling. why my pain, swelling and mild grade fever are not going away completely
