Osteoarthritis of the Knee

Knee pain when climbing stairs, stiffness when you wake up, or a grinding sound when you get up from a chair is easy to dismiss as a normal part of ageing. But when these symptoms keep coming back, they may be early signs of knee arthritis. Osteoarthritis of the knee is one of the most common causes of osteoarthritis knee pain in adults, and it is a major reason people seek knee joint pain treatment.

In this guide, we explain what osteoarthritis of the knee is, its symptoms and causes, how it is diagnosed, and the full range of knee osteoarthritis treatment options, from non-surgical treatment for knee osteoarthritis to knee replacement.

What Is Osteoarthritis of the Knee Joint?

Osteoarthritis of the knee is a degenerative knee joint disease in which the smooth cartilage that cushions the joint thins and roughens over time, causing pain, stiffness and reduced movement.

So, what is osteoarthritis of the knee in practical terms? Your knee is where the thigh bone (femur), shin bone (tibia) and kneecap (patella) meet. Each bone end is covered by articular cartilage, a slippery layer that lets the joint glide. In knee osteoarthritis, that cartilage gradually wears down.

It is not only a cartilage problem. The bone underneath thickens and grows small bony spurs called osteophytes, the joint lining (synovium) becomes irritated, and the joint makes extra fluid. Knee osteoarthritis affects cartilage, bone and the joint lining together, which is why it is now described as a whole-joint disease.

You may see it written as osteoarthritis of knee, knee OA or degenerative knee joint disease. They all describe the same condition.

What Is the Difference Between Knee Arthritis and Osteoarthritis?

Arthritis is the umbrella term for joint damage or inflammation. Osteoarthritis is the most common type of knee arthritis, but not the only one.

When people say knee arthritis, they usually mean osteoarthritis. Other types can affect the knee too, and the treatment is different, so the diagnosis matters.

Type	What is happening	Typical pattern
Osteoarthritis	Gradual wear of cartilage and changes in the bone and joint lining	Pain that builds with activity and eases with rest. Morning stiffness usually settles within 30 minutes.
Rheumatoid arthritis	The immune system attacks the joint lining	Often both knees plus small joints of the hands. Morning stiffness lasting more than an hour.
Gout	Uric acid crystals build up in the joint	Sudden, hot, red, very painful swelling, often overnight.

Early Signs and Symptoms of Knee Osteoarthritis

The early signs of knee arthritis are usually pain that builds with activity, short morning stiffness and a creaking feeling, not constant pain.

Knee osteoarthritis symptoms tend to creep in, and many people ignore them for a year or two. These are the symptoms of knee osteoarthritis to look for:

• Pain after activity. Osteoarthritis knee pain in the early stage often shows up after walking, standing for long, or climbing stairs, and eases with rest.

• Stiffness after rest. The first steps in the morning or after sitting feel tight, and it loosens within about 30 minutes.

• Creaking or grinding (crepitus) when you bend or straighten the knee.

• Mild swelling. The knee looks or feels puffy by the end of the day.

• Trouble with stairs, squatting or standing up from a low seat.

• Tenderness along the inner or outer edge of the joint.

• A tight, unsteady feeling, as if the knee might give way.

As the condition advances, pain begins to appear at rest or at night, the knee may start to bow, swelling stops settling, and your walking distance shrinks.

When to get checked quickly: a sudden hot, red, swollen knee, fever with knee pain, or being unable to put weight on the leg needs assessment the same day. These can point to infection, a fracture or gout rather than osteoarthritis.

What Causes Osteoarthritis of the Knee?

There is rarely a single cause. Several factors work together to damage cartilage over time:

Age: risk rises after 45 to 50 as cartilage loses its ability to repair itself.
Excess body weight: each extra kilo places several kilos of additional load on the knee with every step.
Previous injury: ligament (ACL) tears, meniscus tears or fractures near the knee can lead to arthritis later.
Gender: women, particularly after menopause, are more commonly affected.
Family history: joint problems often run in families.
Repetitive stress: frequent kneeling, squatting, stair climbing or heavy lifting.
Muscle weakness and poor alignment: weak thigh muscles, bow legs or knock knees overload one part of the joint.
Other health conditions: diabetes, inflammatory arthritis and low vitamin D can affect joint health.

Does Knee Osteoarthritis Get Worse with Age?

Osteoarthritis is a progressive condition, so it can worsen over time, and age is a major risk factor. However, growing older does not mean the damage must advance quickly. The pace of progression varies widely from person to person. Maintaining a healthy weight, keeping the thigh muscles strong, avoiding repeated joint stress and starting early knee osteoarthritis treatment can slow the progression and keep many people active for years.

How Is Knee Osteoarthritis Diagnosed?

Knee osteoarthritis is diagnosed mainly from your history and a physical examination, then confirmed with a standing X-ray.

• History. Where it hurts, when it hurts, what makes it worse, and how far you can walk.

• Examination. The doctor checks swelling, tenderness, range of movement, alignment of the leg and the way you walk.

• Weight-bearing X-ray. It shows narrowing of the joint space, bony spurs and hardening of the bone. A standing X-ray is more useful than one taken lying down.

• MRI. Not needed for everyone. It helps when the X-ray does not explain your symptoms, or when a meniscus or ligament injury is suspected.

• Blood tests. Used when the pattern suggests rheumatoid arthritis or gout.

One thing worth knowing: X-ray changes and pain do not always match. Some people with clearly visible changes have mild symptoms, and some with early cartilage damage have significant pain. Treatment is based on how your knee behaves, not on the picture alone.

Stages of Knee Osteoarthritis: Understanding the Grades

Doctors commonly grade knee osteoarthritis from grade 1 to grade 4 (often using the Kellgren-Lawrence system based on X-ray findings). Knowing your grade helps decide the right treatment.

Grade 1 (doubtful): very minor changes, such as a tiny bone spur. Symptoms are usually minimal.
Grade 2 (mild): definite bone spurs with possible slight joint space narrowing. Occasional pain and stiffness begin.
Grade 3 (moderate): clear narrowing of the joint space with more noticeable pain, swelling and stiffness.
Grade 4 (severe): little or no cartilage is left between the bones, often described as bone on bone knee arthritis, with significant pain and limited movement.

Knee Osteoarthritis Treatment Options

Can early knee arthritis be reversed? Cartilage that has worn away cannot currently be fully regrown, so true reversal is not possible. However, in the early stages, the right treatment can greatly reduce symptoms, improve function and slow further damage. Treatment for osteoarthritis of the knee is planned according to your grade, symptoms, age and lifestyle, and most people start with non-surgical options.

1. Can Knee Osteoarthritis Be Treated Without Surgery?

Yes. Most people with knee osteoarthritis are treated without surgery, and non-surgical treatment for knee osteoarthritis is the first step at every stage.

Knee arthritis treatment is built in layers. The table lists each of the knee osteoarthritis treatment options with its limits first, because none of them is a cure. Together they are what a good plan for treatment for osteoarthritis of the knee is made of, and the same layers apply whether you are looking at treatment for osteoarthritis in knees on one side or both.

Option	Limits and drawbacks	Where it helps
Weight management	Slow and needs sustained effort. Does not repair cartilage.	Lowers load on the joint. Useful at every stage.
Physiotherapy and exercise	Benefit fades if you stop. Pain can flare a little when you begin.	Strengthens the muscles that protect the knee. Strongest evidence overall.
Anti-inflammatory gels	Modest relief. Can irritate skin.	Often safer than tablets for long-term use.
Oral painkillers and NSAIDs	Stomach, kidney, blood pressure and heart risks with long use. Relief is temporary.	Short courses for flare-ups, under a doctor’s guidance.
Walking stick, brace, footwear changes	Braces can be uncomfortable. Evidence for insoles is limited.	Takes load off a painful side.
Corticosteroid injection	Relief often lasts weeks to a few months. Repeated shots may not be good for cartilage. Can raise blood sugar for a few days.	Short-term relief for a painful, swollen flare.
Hyaluronic acid injection	Evidence is mixed and the benefit is modest. Several guidelines do not recommend it routinely.	May help some people with mild to moderate disease.
PRP injection	Evidence varies, there is no standard preparation, and the cost is often out of pocket.	Mild to moderate disease, mainly early stage.
Stem cell therapy	Still investigational in India, unproven and expensive.	Only within properly approved clinical trials.

For day-to-day knee osteoarthritis pain relief, simple habits matter more than most people expect. Warmth before activity loosens the joint, a cold pack after a flare calms swelling, and pacing your walks avoids overloading the knee. If you are looking for knee joint pain treatment that lasts, the exercise and weight steps are the ones that keep working after the pain settles.

2. Best Exercises for Knee Osteoarthritis

What is the best exercise for knee osteoarthritis? No single exercise suits everyone, but a combination of strengthening and low-impact activity works best. Commonly advised options include:

Straight leg raises and quadriceps sets: strengthen the thigh without bending the painful knee.
Hamstring curls and calf raises: support the knee from behind and below.
Mini squats and sit-to-stand exercises: done within a pain-free range, using a chair for support.
Stationary cycling: improves mobility with low joint stress.
Swimming and water walking: the water supports body weight and is gentle on the knees.
Walking on level ground: at a comfortable pace, with good footwear.

Avoid deep squats, high-impact jumping and running on hard surfaces if they cause pain. Ask your doctor or physiotherapist to tailor exercises to your grade of arthritis.

3. Medicines for Knee Osteoarthritis Pain Relief

Medicines help with knee osteoarthritis pain relief and allow you to stay active and keep exercising. These may include paracetamol, anti-inflammatory tablets (NSAIDs), pain-relief gels or creams applied to the knee, and vitamin D or calcium if a deficiency is found. Take painkillers only as advised, because long-term use of NSAIDs can affect the stomach, kidneys and heart.

4. Knee Osteoarthritis Injections

When tablets and exercise are not enough, knee osteoarthritis injections may be considered:

Corticosteroid injections: reduce inflammation and can provide short-term relief during a painful flare-up. They are not suitable for frequent repetition.
Hyaluronic acid (viscosupplement) injections: aim to improve joint lubrication and may benefit some people with mild to moderate arthritis.
PRP injection for early osteoarthritis: platelet-rich plasma is prepared from a small sample of your own blood and injected into the knee. Studies suggest it may reduce pain and improve function in early to moderate osteoarthritis for some patients, although results vary and it is less likely to help in advanced, bone-on-bone arthritis.

5. Stem Cell Therapy for Knee Osteoarthritis

Stem cell therapy for knee osteoarthritis, which uses cells usually taken from bone marrow or fat tissue, has received a great deal of attention. It is still considered an evolving treatment. Research is ongoing, and the long-term benefits, best methods and cost-effectiveness are not yet firmly established. It is important to discuss realistic expectations with a qualified orthopedic specialist and to be cautious of any clinic that promises to “regrow” your knee cartilage.

6. Braces, Supports and Walking Aids

A knee brace, insoles or a walking stick can reduce pressure on the painful side of the knee and improve stability. A stick held in the hand opposite the painful knee is often helpful.

7. Surgical Treatment

Surgery is considered when pain is severe, movement is badly limited and non-surgical treatment has stopped working. Options include:

Osteotomy: the bone is reshaped to shift weight away from the damaged area. It is mainly considered for younger, active patients with arthritis on one side of the knee and clear misalignment.
Partial knee replacement: only the damaged compartment is replaced, preserving healthy parts of the knee.
Total knee replacement: the damaged joint surfaces are replaced with a metal and medical-grade plastic implant. It is a well-established procedure that relieves pain and improves mobility in most patients with advanced arthritis.

When Does Knee Osteoarthritis Require Knee Replacement?

Knee replacement may be recommended when:

Pain is severe and constant, including at night or at rest
Walking, climbing stairs or getting up from a chair has become very difficult
X-rays show advanced arthritis (grade 3 to 4, bone on bone)
Physiotherapy, medicines, injections and supports no longer help
The deformity or instability is increasing

The decision depends on how much the condition affects your quality of life, not on the X-ray alone, and is made together with your orthopedic surgeon.

When Should You See an Orthopedic Doctor?

You do not need to wait for severe pain. Consult an orthopedic specialist if:

Knee pain lasts more than a few weeks or keeps returning
Stiffness or swelling is becoming more frequent
Pain affects your sleep, walking or daily activities
The knee looks deformed, locks, catches or feels unstable
Painkillers no longer give relief

If you are in or around Erandwane, Kothrud, Deccan or other parts of Pune, you can consult Dr. Ketaki Mohite, Orthopedic Doctor in Erandwane,Pune, for an evaluation of your knee pain.

Seek urgent care if the knee suddenly becomes very painful, hot, red and swollen, or if you cannot bear weight on the leg, as this may indicate infection or another serious problem.

Knee Osteoarthritis Treatment in Pune

If you are searching for knee osteoarthritis treatment in Pune, Dr. Ketaki Mohite, Orthopedic Surgeon , can evaluate your knee symptoms and help you understand the available treatment options. A clinical examination and appropriate X-rays help assess the condition before considering injections or surgery.

Options for knee pain treatment in Pune range from physiotherapy and lifestyle modifications to injections and knee replacement surgery, depending on the severity of osteoarthritis. When consulting an orthopedic doctor for knee pain in Pune, consider whether they:

Explain your X-ray findings and the severity of knee osteoarthritis in simple language.
Discuss physiotherapy, suitable exercises and other non-surgical treatment options.
Explain the potential benefits, limitations and costs of treatments such as PRP or hyaluronic acid injections.
Discuss knee replacement surgery when appropriate and explain alternative options.

Your daily routine also matters when planning knee pain management. Climbing stairs in older buildings, using Indian-style toilets, sitting on the floor for meals or puja, and long two-wheeler commutes can increase knee discomfort. Changes such as using a raised toilet seat, choosing a low stool for floor-based activities and modifying activities may help reduce strain.

Before your consultation with Dr. Ketaki Mohite, Orthopedic Surgeon in Erandwane, Pune, carry previous X-rays or MRI reports, a list of current medicines and recent blood sugar or blood pressure readings, if available. This information can help support a more informed discussion about your knee health and suitable treatment options.

Frequently Asked Questions (FAQs)

What are the early signs of osteoarthritis in the knee?

Early signs include pain while walking or climbing stairs, morning stiffness that eases with movement, mild swelling, a cracking or grinding feeling in the knee, and difficulty fully bending the knee.

Is walking good for knee osteoarthritis?

Yes. Regular walking on flat ground helps keep the joint moving and the muscles strong. Build up gradually and avoid steep slopes and hard surfaces if they make the pain worse the next day.

Can knee osteoarthritis cause pain at night?

In the early stage, night pain is uncommon. Pain that wakes you regularly usually means the joint is more advanced or inflamed, and it is a good reason to get examined.

How long does a PRP injection last?

Studies in mild to moderate knee osteoarthritis report benefit lasting around 6 to 12 months for some people, but results vary and some people notice little change.

Do I need an MRI for knee pain?

Not usually. A good examination and a standing X-ray are enough to diagnose osteoarthritis. An MRI is reserved for suspected meniscus or ligament injury, or when the X-ray does not explain your symptoms.

Which doctor should I see for knee pain?

Start with an orthopedic doctor. They will assess the joint, order tests and refer you to a physiotherapist or other specialists if needed.

Which doctor should I consult for knee osteoarthritis in Pune?

An orthopedic specialist is the right doctor for knee pain and arthritis. You can consult Dr. Ketaki Mohite, Orthopedic Surgeon in Erandwane, Pune, for diagnosis and a personalised treatment plan.
