Many nonsurgical treatments are touted as being able to ease the symptoms of knee osteoarthritis, but which ones really work? Last year, the American Academy of Orthopaedic Surgeons (AAOS) issued revised recommendations, updating its 2009 guidelines. The group made two important changes that may affect the way you manage knee osteoarthritis.
- First, if you use acetaminophen (Tylenol) for osteoarthritis pain relief, take no more than 3,000 mg per day. The AAOS formerly advised not exceeding 4,000 mg daily. The change was made to reflect the Food and Drug Administration’s current guidelines for safe use of acetaminophen.
- Second, the AAOS found insufficient evidence that intra-articular hyaluronic acid provides significant symptom relief for knee osteoarthritis so the organization no longer recommends the therapy.
The AAOS continues to give a thumbs-up to some familiar commonsense strategies, such as exercising and a minimum 5 percent weight loss for people whose body mass index (BMI) is greater than 25.
Other highlights: The AAOS is unable to recommend for or against the use of bracing, growth factor injections and/or platelet-rich plasma knee osteoarthritis. In addition, although acupuncture continues to grow in popularity, there is not sufficient scientific evidence to support its use in patients with knee osteoarthritis.
