ROSEMONT, Illinois, July 2, 2026
The American Academy of Orthopaedic Surgeons (AAOS) has released its first-ever Clinical Practice Guideline (CPG) for the Management of Ankle Osteoarthritis (OA), providing evidence-based recommendations for the diagnosis and treatment of one of the most challenging musculoskeletal disorders affecting younger and active patients. Unlike hip and knee osteoarthritis, which primarily affects older adults, ankle osteoarthritis frequently develops in younger, working-age individuals, often following traumatic injuries and significantly impacting mobility, productivity, and quality of life. The newly published guideline represents an important milestone in orthopedic medicine by establishing standardized recommendations for both non-operative and operative management of symptomatic ankle OA while identifying major evidence gaps that require future clinical research. Although the current scientific literature remains limited, AAOS believes the guideline will help orthopedic surgeons and healthcare professionals make informed treatment decisions through evidence-based medicine and shared decision-making with patients.
AAOS Recommends Against PRP and Hyaluronic Acid Alone for Ankle OA
One of the most significant conclusions of the new Clinical Practice Guideline is the recommendation against the routine use of intra-articular platelet-rich plasma (PRP) for patients with symptomatic ankle osteoarthritis. After reviewing the available clinical evidence, the guideline workgroup issued a moderate recommendation stating that PRP injections do not provide superior pain relief compared with placebo saline injections despite their growing popularity in regenerative medicine. The guideline also includes a strong recommendation against using intra-articular hyaluronic acid (HA) alone for treating ankle OA because current evidence does not demonstrate meaningful long-term clinical benefit.
However, researchers noted that combining hyaluronic acid with corticosteroid injections may provide improved short-term pain relief and functional improvement compared with either therapy alone, although standardized treatment protocols remain unavailable. The workgroup emphasized that additional high-quality randomized clinical trials are needed to better define the effectiveness of biologic therapies and optimize treatment strategies for patients suffering from ankle osteoarthritis.
Guideline Highlights Physical Therapy, Conservative Care and Evidence Gaps

Beyond injection therapies, the AAOS guideline presents 11 consensus recommendations and one limited-strength recommendation covering several aspects of conservative and post-surgical management. The guideline states that intra-articular corticosteroid injections may provide short-term symptom relief, while emphasizing that there is currently no reliable evidence supporting stem cell therapy for symptomatic ankle osteoarthritis. The workgroup also highlights the important role of skilled physical therapy, indicating that patients with mild-to-moderate ankle OA who wish to postpone surgery may experience improvements in pain, mobility, strength, gait, and overall patient-reported outcomes. For individuals undergoing surgical treatment, physical therapy remains essential for restoring function and facilitating return to work and daily activities.
Additionally, the guideline recommends avoiding prescription opioids whenever possible for ankle OA management while supporting the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen as first-line options when medically appropriate. Weight reduction is also recognized as an important strategy that may improve symptoms and potentially slow disease progression, reinforcing the value of comprehensive lifestyle management alongside clinical treatment.
First Guideline Sets Foundation for Future Orthopedic Research
According to the AAOS workgroup, the publication of this first ankle osteoarthritis guideline represents the beginning of a broader effort to improve clinical care and stimulate future research into definitive treatment strategies. While the current guideline focuses primarily on evidence-based recommendations for symptom management, researchers acknowledge that additional studies are urgently needed to evaluate long-term outcomes of joint-preserving procedures, ankle arthrodesis, and total ankle arthroplasty. The organization hopes future guideline updates will include stronger recommendations for surgical interventions as more high-quality evidence becomes available.
The guideline also encourages shared decision-making between orthopedic surgeons and patients, ensuring treatment choices are tailored to individual clinical circumstances, lifestyle goals, and disease severity. By establishing standardized recommendations and identifying important research priorities, the AAOS Clinical Practice Guideline for the Management of Ankle Osteoarthritis is expected to enhance evidence-based orthopedic care, improve patient outcomes, and guide future innovations in musculoskeletal medicine for one of the most underserved osteoarthritis populations.
