For some, lifestyle modifications, physical therapy, medication, or alternative treatment methods such as acupuncture and prolotherapy (which involves injecting fluid to strengthen connective tissue) can help manage knee problems. Also, you may want to speak to your surgeon about other procedures that are commonly recommended before resorting to knee replacement surgery, including steroid or hyaluronic acid injections and arthroscopic surgery that addresses the damaged cartilage. However, delaying or declining a necessary knee replacement could result in a less favorable outcome. Ask yourself: Have I tried everything? Is my knee holding me back from doing the things I enjoy?
