I understand this diagnosis sounds alarming, but these injuries are highly treatable with proper care. To manage pain and reduce swelling, nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen are very effective. Acetaminophen can also be used for additional pain relief. For the subchondral fracture, calcium and vitamin D supplements may be recommended to support bone healing. If pain is severe, your doctor may prescribe stronger temporary pain relievers. Please note that medications only manage symptoms; actual recovery requires joint protection, physical therapy, and close coordination with an orthopedic specialist, who will determine if the PCL avulsion requires surgical fixation.
