Introduction
Our bodies depend heavily on the ankle joint. The ankle serves as a junction for tendons, connective tissues, and cartilage of the lower leg to the foot. The ankle is where the muscles, tendons, and ligaments needed for walking, running, and leaping meet and are at their lowest point. It is required for speed and balancing. Due to all the strain these muscles and tendons exert in the ankle joint, the cartilage is susceptible to injury, leading to a condition known as arthritis. Movement becomes uncomfortable as less fluid is present in the cartilage, which covers a joint's surface to facilitate movement, and is injured.
Even though ankle arthritis might be painful, it is important to know what stage it is at for appropriate treatment. As a degenerative condition, arthritis becomes worse the longer it is ignored. In healthy ankles, cartilage covers the joints to prevent friction during the early stages of ankle arthritis. This cartilage starts to deteriorate in arthritic ankles, which makes it possible for surface abnormalities and pitting to emerge. After a long day of walking or spending a lot of time sitting still, the ankle may feel unpleasant or stiff. This is thought to be the early stages of ankle arthritis.
Early on, it might be difficult to separate this pain from everyday discomfort, which can be troublesome. At this stage of ankle arthritis, it is crucial to see a doctor so that measures may be put in place in time to reduce the condition's progression. Certain NSAIDs (nonsteroidal anti-inflammatory drugs), such as Ibuprofen or Naproxen, can be taken to treat this stage of ankle arthritis, combined with supportive footwear, low-impact exercise, and an active, healthy lifestyle. It has been established that low-impact aerobic exercise is optimal for cartilage health. Keep in mind that no exercise is helpful for cartilage.
In mid-stage ankle arthritis, bone spurs form in reaction to aberrant cartilage. So, at this point, people start to notice some discomfort and suffering that might not be typical. The presence of waves of the changing intensity of pain throughout the day as well as sporadic swelling, will make the symptoms more obvious. At this stage, resting sometimes and relieving pressure on the ankle could be required. This can be beneficial in the short run. However, it is best to maintain some level of activity in order to keep the muscles healthy and able to support the ankle joint over the long run.
Continuing to take NSAIDs, engaging in low-impact exercise, and consulting an orthopedic surgeon to identify the next steps are some treatments for this stage of arthritis. Surgery may be considered at this point to get rid of spurs, fix joints, or realign or stabilize the ankle. Socks with cushions and bracing are frequently beneficial.
What Is an End-Stage Ankle Osteoarthritis?
The articular cartilage cushion that borders the joint gradually becomes worn down in end-stage osteoarthritis of the ankle joint, eventually leading to the grinding of the joint's surface against other bones. This "end-stage" of arthritis causes pain, loss of function, and immobility, which significantly restricts daily activity. People affected with end-stage osteoarthritis are given three surgical treatment options, including ankle fusion (also known as arthrodesis), total ankle replacement (TAR), and, in some circumstances, distraction arthroplasty, once this end stage has been reached and non-operative options (such as medication, injections, and bracing) have been insufficient to provide symptoms and signs free.
The cartilage around the joint is nearly completely eroded in the late stages of ankle arthritis, leaving very little room between the bones and restricting mobility. This may apply to the entire joint or just a specific area of it. Additionally, the spurs may get rather big. The ankle will be extremely stiff and occasionally entirely immobilized at this point. Simple tasks like crouching and climbing stairs may become difficult. As the disease progresses, the lubricating fluid in the joints evaporates, increasing the friction between the bones. Moving at this point might be unpleasant and perhaps harmful to the bones. Previous treatments (such as NSAIDs and mild exercise) might not be sufficient to treat arthritis at this stage.
What Are the Signs and Symptoms of End-Stage Ankle Osteoarthritis?
-
Tenderness to touch at the joint.
-
Ankle joint discomfort and edema, with symptoms made worse by standing and moving about.
-
Difficulty walking, moving, or bearing weight on it.
-
Stiffness, warmth, or swelling in the joints.
-
After resting, such as while sitting or sleeping, there is more discomfort and swelling.
What Are the Risk Factors for End-Stage Ankle Osteoarthritis?
-
Older Age- Age raises one's chance of developing osteoarthritis.
-
Sex- Women are more prone to be affected by osteoarthritis.
-
Obesity- Osteoarthritis is exacerbated by excess body weight in a number of ways, and the risk increases with weight.
-
Joint Damage or Injury- Osteoarthritis risk can be boosted by injuries, such as those sustained in accidents or when participating in sports. The risk of osteoarthritis might be increased even by wounds that seemed to heal years ago.
-
Constant Pressure on the Joint- Osteoarthritis may eventually develop in a joint if repetitive stress is applied to it due to the occupation or participation in a sport.
-
Genetics- Some people have an inherited propensity to have osteoarthritis.
-
Bone Anomaly- Some people may be born with faulty cartilage or deformed joints, increasing the risk of developing osteoarthritis.
-
Certain metabolic conditions, such as diabetes, and iron overload disorder, that are referred to as hemochromatosis.
How Is End-Stage Ankle Osteoarthritis Diagnosed?
No matter how the condition of the ankle is, each patient will need specific therapy based on their demands. Age, activity level, body weight, bone stock quality, overall foot alignment, stability, and the severity of the arthritic condition are all factors in deciding the best course of action. A doctor will perform a physical exam and order X-rays to detect some of these issues.
How Is End-Stage Ankle Osteoarthritis Treated?
There are numerous choices available when ankle arthritis has progressed to an end stage when non-surgical means of therapy are no longer viable. An orthopedic surgeon who specializes in foot and ankle surgery will take into account a variety of criteria while deciding the best course of therapy for each patient, including age, activity level, body weight, bone quality, alignment, and arthritis severity.

Arthrodesis or Fusion
Patients have often had an arthrodesis, or fusion, a surgery dealing with end-stage arthritis. This method employs raw bone surfaces that are kept together with metal plates and/or screws until the bone surfaces combine or fuse. Ankle joint mobility will be lost, but pain relief is achieved by fusion, which fixes the joint in the proper place.
Typically, the ankle is in a cast for 8 to 12 weeks. Patients still benefit from this surgery as a form of pain reduction. However, there are issues with arthrodesis techniques. An ankle fusion leads to a loss of mobility; therefore, the surrounding joints flex and lengthen to make up for it. The crucial consideration is that these nearby joints face the danger of developing arthritis themselves, even though this enables the majority of fusion patients to walk without a limp.
-
Total Ankle Replacement (TAR)
Instead of fusing the joint, this surgery depends on replacing the arthritic surfaces with an artificial implant constructed of two or three parts that glide against one another using low-friction materials. With preserved ankle mobility, pain reduction is the main advantage. Although there are no long-term studies, this treatment has been demonstrated to offer a functional range of motion in the ankle, allowing patients to actively participate in daily activities. More significantly, TAR causes less stress to be placed on the nearby joints, which lowers the likelihood of arthritis in the surrounding regions as well.
-
Distraction Arthroplasty
Distraction arthroplasty, a surgical procedure targeted at younger patients that entails positioning the ankle in a framework of pins set into the bones and gradually adjusting that framework in order to distract (pull apart) the joint surfaces, is a third option for some patients with end-stage arthritis. Theoretically, this helps the body produce new ankle cartilage.
For the treatment to be effective, the patient's foot must be properly aligned. Ankle discomfort usually considerably decreases after one year, with the fixator retaining the pins around the ankle normally in place for ten weeks. According to studies, this technique has a 60 % success rate.
Conclusion
Ankle joint pain and swelling are indications of end-stage ankle arthritis, an agonizing condition that is aggravated by standing and moving around. There is not much cartilage remaining, and the ankle joint will become stiff in end-stage ankle arthritis. Ankle fusion or ankle replacement is often the option for treatment at that stage, which is reported to be effective. Treatment is largely individualized, taking into account the patients' general health and extent of physical activity.
