Osteoarthritis of the Knee: Symptoms, Causes & Treatments
Osteoarthritis or (OA) of the knee is a common condition that affects millions of people worldwide. It can cause pain, stiffness, and swelling in the affected joint. The causes of osteoarthritis in the knee can range from age-related wear and tear to injury or genetics. Common symptoms include joint pain, limited range of motion, and stiffness. Fortunately, there are a variety of treatments available to help manage the symptoms of osteoarthritis.
What is osteoarthritis?
Osteoarthritis is a degenerative joint disease that affects the cartilage and bones in the knee. It occurs when the protective cartilage that covers the bones of the knee wears down over time, causing the bones to rub against each other. This leads to pain, stiffness, and loss of movement in the joint. Osteoarthritis is the most common form of arthritis and affects millions of people worldwide.
Symptoms of Knee osteoarthritis includes:-
- Decreased range of motion
- Sounds when the joint moves
- An overall feeling of stiffness.
In severe cases, the knee may become enlarged and lose its shape. The cause of OA is unknown, but certain factors can increase your risk such as age, obesity, and previous injuries to the knee. Treatment for OA of the knee typically includes physical therapy, medications, lifestyle changes, and in some cases, surgery.

What causes Knee osteoarthritis?
Knee osteoarthritis is a common degenerative joint disease that affects millions of people. Here are 10 causes of OA of the knee.
- Age: Osteoarthritis is more likely to develop as people age above 50.
- Injury: Injury to the joint, such as a fracture or ligament tear, can lead to OA in the knee over time.
- Overuse: Repetitive motions, such as those used in certain sports or occupations, can cause wear and tear on the knee joint and increase the risk of developing OA.
- Obesity: Extra weight places extra strain on the knee joint and can accelerate the development of OA.
- Genetics: Certain genetic conditions can make a person more likely to develop osteoarthritis of the knee.
- Gender: Women are more likely to develop the condition than men.
- Joint instability: Instability of the knee joint can lead to an increased risk of developing OA.
- Metabolic disorder: Certain metabolic disorders, such as diabetes, can cause damage to the joint and increase the risk of developing osteoarthritis.
- Infection: Infection of the joint can cause inflammation and increase the risk of developing osteoarthritis.
- Poor nutrition: A lack of essential vitamins and minerals can lead to joint deterioration, which can cause the development of OA in the knee.
What are the Stages of Knee Osteoarthritis?
When it comes to OA of the knee, there are four distinct stages which may occur over the course of the condition. Understanding these stages can help patients manage their symptoms and also allow for early intervention and treatment.
Stage 1: Mild Osteoarthritis
The first stage, or mild OA of the knee, is characterized by minor pain and stiffness in the affected joint. At this stage, the cartilage that lines the bone surfaces of the knee joint is beginning to break down, but there is no major damage present. The person affected may experience difficulty moving the leg or joint, but these symptoms are likely to be minor and manageable.
Stage 2: Moderate Osteoarthritis
By the second stage of knee osteoarthritis, the pain and stiffness in the knee has become more pronounced, as the cartilage continues to break down. This stage is usually accompanied by inflammation and swelling in the knee joint, as well as a loss of mobility.
Stage 3: Severe Osteoarthritis
The third stage of knee osteoarthritis is usually characterized by significant pain, swelling and stiffness in the knee joint. Damage to the cartilage is extensive, and the person may find that their knee is permanently stiff and unable to move as far or as freely as before.
Stage 4: Fourth Stage
The fourth, or ‘end stage’ of knee osteoarthritis is the most severe. At this stage, the joint is severely damaged and the person affected is likely to experience chronic pain, stiffness and immobility in the affected knee. In some cases, the knee joint may be fused together, meaning that it can no longer move at all.
How can I treat my osteoarthritis of the knee?
- The condition is progressive and can worsen over time, but there are a variety of treatments available to help manage the symptoms and prevent the condition from progressing.
- The first step in is to make lifestyle changes that reduce stress on the joints. Weight loss is important as excess weight can put extra strain on the knees, and exercise, such as low-impact activities, is important for maintaining joint flexibility and strength. Additionally, a physical therapist can show you exercises to improve range of motion and reduce pain.
- Medications are also available to help reduce pain and inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce inflammation and ease the pain, while corticosteroid injections can provide direct relief to the joint.
Are there any surgical options?
- When it comes to OA of the knee, surgery is an option that can be considered when all other treatments have been exhausted. Surgery may be used to address issues such as pain and instability, as well as to improve the function of the joint.
- For those suffering from knee pain and other symptoms, surgical options may include arthroscopy, arthroplasty, or osteotomy.
- Arthroscopy is a minimally invasive surgical procedure in which a small camera is used to view the inside of the knee joint. This procedure can be used to repair or remove damaged tissue or to clean out debris in the joint.
- Arthroplasty, also known as joint replacement surgery, is another surgical option for those with osteoarthritis in the knee.
- Osteotomy is a more specialized type of surgery used in severe cases of osteoarthritis in the knee.
- No matter what type of surgery you choose, it is important to consult with your doctor first to determine if it is an appropriate option for you. Your doctor can evaluate your condition and recommend the best course of action for treating your osteoarthritis knee pain.
What are the long-term effects of osteoarthritis?
- Osteoarthritis of the knee can cause persistent and often debilitating pain, making it difficult to perform daily activities. In the long-term, untreated knee osteoarthritis can lead to disability and loss of quality of life. Long-term effects may include chronic osteoarthritis knee pain, decreased range of motion, and joint deformity.
- In addition, osteoarthritis of the knee can increase risk of other health conditions such as obesity, diabetes, cardiovascular disease, and depression. Furthermore, joint damage caused by osteoarthritis in the knee may eventually necessitate joint replacement surgery.
- For those suffering from knee osteoarthritis, it is important to take proactive measures to manage the condition. This includes maintaining a healthy weight, avoiding high-impact activities and exercises, following a physical therapy regimen, and taking medications as prescribed. By taking these measures, individuals can reduce their risk of long-term effects and maintain mobility and function.
frequently asked questions?
- Can knee osteoarthritis be cured?
There is no specific cure for knee osteoarthritis, but it can be managed with lifestyle modifications and treatments. The goal of treatment is to reduce pain and improve joint function.
- Is osteoarthritis knee pain worse in the morning?
