If ankle pain persists and even walking becomes uncomfortable, it is necessary to suspect ankle arthritis rather than a simple sprain or temporary pain. Ankle arthritis is a condition where the cartilage wears down, narrowing the joint space and causing pain and stiffness during movement. It often occurs when the joint alignment remains misaligned following a past ankle ligament injury or fracture.

The problem is that ankle arthritis is often detected relatively later than knee arthritis. It begins with simple fatigue or stiffness, but as time passes, the pain becomes more frequent, and it can progress to a state where it is difficult to properly bear weight while walking. Reaching this stage results in restrictions not only in daily life but in overall activities.

Treatment for ankle arthritis is largely divided into non-surgical and surgical methods. In the early stages, one can attempt to control symptoms through medication, physical therapy, and the use of braces. However, if pain persists while the joint alignment is collapsed, or if weight is excessively loaded on one side, structural correction may be required.

One of the surgeries considered in such cases is SMO (Supramalleolar Osteotomy). SMO surgery involves osteotomy of the tibia above the ankle to correct tilted joint alignment and distribute the load concentrated on a specific area. Simply put, it can be understood as a joint preservation surgery that reduces the burden on the joint by changing the direction of weight-bearing rather than directly treating the worn-out cartilage.

One characteristic of ankle arthritis is that, rather than the entire joint being damaged uniformly, specific areas often wear down intensively. In this case, correcting the alignment through SMO surgery allows the load to shift to relatively preserved cartilage areas, enabling both pain relief and functional recovery.

Previously, joint fusion to fix the joint or total ankle replacement were considered the primary surgeries as ankle arthritis progressed. Recently, however, joint preservation surgeries like SMO are being actively applied to patients in the relatively early to mid-stages. This can be seen as a treatment trend focused on reviving natural walking functions while maintaining the joint as much as possible.

However, SMO surgery is not applied to every patient with ankle arthritis. Indications must be determined by comprehensively evaluating the scope of joint damage, the direction of deformity, ligament stability, and the patient's activity level. In the terminal stage, where the overall joint is severely damaged, other surgical methods may be more appropriate.

Located in Gangdong-gu, Seoul, Seoul Gunwoo Orthopedic Clinic is a medical institution that professionally treats foot and ankle disorders, including ankle arthritis. The clinic actively considers joint preservation treatments such as SMO surgery for ankle arthritis patients with joint misalignment. The clinic's goal is not simply to reduce pain, but to restore both the alignment and function of the ankle.

Director Hong-Joon Choi of Seoul Gunwoo Orthopedic Clinic holds a Ph.D. from Korea University and conducted research in the field of foot and ankle at Massachusetts General Hospital (MGH), an affiliate of Harvard Medical School, and continues his clinical experience in foot and ankle disorders. This background shows that a more precise approach is being taken toward structural diseases like ankle arthritis.

What is important in the treatment of ankle arthritis is not simply enduring the pain, but accurately identifying which stage the current joint condition is in. In particular, if pain is concentrated in only one ankle or if there is a feeling of weight shifting to one side while walking, it is necessary to suspect a misalignment.

SMO surgery is an important option for preserving the joint by correcting these alignment issues. When performed at the appropriate time, it can help improve the quality of daily life while maintaining joint function.

Seoul Gunwoo Orthopedic Clinic provides customized treatments including SMO surgery to ankle arthritis patients based on foot and ankle-centered care. The clinic specifically focuses on restoring the patient's walking function and maintaining long-term joint health through treatment strategies aimed at preserving the joint as much as possible.
