Surgery? degeneration posterior horn of meniscus, tendinosis/partial thickness tearing of patellar tendon at interpolar patella, subcutaneous edema

When nonop tx fails: Surgery is not usually the first line of treatment for chronic injuries such as you described: degenerative (chronic) PHMMT, and patellar tendinosis (vs partial inferio pole tear). Nonoperative management: physical therapy, stretching program, NSAIDs, rest, ice, may all help considerably. Arthroscopy to debride a degenerative meniscal tear due to persistent mechanical symptoms may be needed later.
