General treatment methods are mainly divided into two categories. First, conservative treatment, which is non-surgical and includes rest, immobilization, localized physical therapy such as heat application, acupuncture, etc. Physical therapy includes techniques like spectrum therapy, infrared, and diathermy. For some patients with mild osteoarthritis and minor effusions, these can gradually be absorbed over one to two weeks, and symptoms of pain and swelling can be alleviated. This can be combined with oral intake of non-steroidal anti-inflammatory drugs (NSAIDs), such as celecoxib or ibuprofen. For patients with recurrent episodes, or those who are middle-aged and above with severe osteoarthritis and degeneration, and have substantial effusion, conservative treatments are generally not very effective. Therefore, we can try aspirating the effusion in the knee joint and appropriately administer intra-articular sodium hyaluronate injections to promote the recovery of osteoarthritis and delay the degeneration of bone proliferation. If conservative treatment still does not bring significant relief, then arthroscopic debridement and corresponding surgical treatments for the knee joint may be considered.
