Chondromalacia patella for around 4 months, physical therapy did not help, some options to help the knee get better without surgery?

Consider Surgery: Conservative management of Chondromalacia patella includes icing, taping, bracing, and exercise to stabilize your patella. If PT with exercise and icing/taping did not help,an Orthopaedic Surgeon can evaluate you for patella alta or baja, put a camera into your knee to look for a plica, remove damaged cartilage, and give an expert opinion of your biomechanical foot/knee/patellar alignment.
