Arthritis of the Knee: Symptoms, Stages & Treatment Options

By Dr. Vinayaraj M. Kelagadi, Orthopedic, Joint Replacement & Spine Specialist, Kossin Care, Bangalore

Knee arthritis is one of the most common causes of chronic knee pain and disability, especially among middle-aged and elderly individuals. However, it is increasingly being seen in younger people due to lifestyle factors, obesity, injuries, and repetitive strain. Early diagnosis and timely treatment can significantly slow disease progression and improve quality of life. In this blog, I will explain what knee arthritis is, its symptoms, stages, and the latest treatment options available.

What Is Knee Arthritis?

Knee arthritis occurs when the protective cartilage that cushions the knee joint gradually wears away. As cartilage thins, bones begin to rub against each other, causing pain, stiffness, swelling, and reduced movement.

Common Types of Knee Arthritis

• Osteoarthritis (OA) – Age-related wear and tear (most common)

• Rheumatoid Arthritis (RA) – Autoimmune condition causing joint inflammation

• Post-Traumatic Arthritis – Develops after knee injury or surgery

Symptoms of Knee Arthritis

Knee arthritis symptoms usually progress slowly and worsen over time:

• Persistent knee pain (during walking or even at rest)

• Stiffness, especially in the morning or after sitting

• Swelling and tenderness around the knee

• Reduced range of motion

• Grinding or cracking sound while moving

• Difficulty climbing stairs or standing up from a seated position

• Knee deformity in advanced stages

Early symptoms are often ignored, leading to delayed treatment.

Stages of Knee Arthritis

Stage 1: Early (Mild)

• Minimal cartilage damage

• Occasional pain or discomfort

• No major movement restriction

Stage 2: Mild to Moderate

• Noticeable cartilage thinning

• Pain during walking or activity

• Mild swelling and stiffness

Stage 3: Moderate

• Significant cartilage loss

• Frequent pain and stiffness

• Difficulty with daily activities

Stage 4: Severe

• Complete cartilage loss

• Severe pain even at rest

• Joint deformity and major mobility limitation

Diagnosis of Knee Arthritis

Accurate diagnosis is essential to choose the right treatment:

• Clinical examination

• X-rays to assess joint space narrowing

• MRI in selected cases

• Blood tests (for inflammatory arthritis)

Treatment Options for Knee Arthritis

Non-Surgical Treatments (Early to Moderate Stages)

• Lifestyle modification and weight management

• Physiotherapy and strengthening exercises

• Pain-relief and anti-inflammatory medications

• Knee braces or supports

• Injections (Hyaluronic acid, PRP, or corticosteroids)

Many patients can delay or avoid surgery with proper conservative care.

Surgical Treatments (Advanced Stages)

When non-surgical treatments fail and pain affects daily life:

• Arthroscopy (selected cases)

• Partial Knee Replacement

• Total Knee Replacement (TKR) – Highly effective for end-stage arthritis

Modern knee replacement surgeries offer:

• Faster recovery

• Long-lasting implants

• Significant pain relief

• Improved mobility and independence

When Should You See a Knee Specialist?

• Knee pain lasting more than 2–3 weeks

• Difficulty walking or climbing stairs

• Swelling that does not reduce

• Pain interfering with sleep or daily routine

Early consultation helps preserve joint health and prevents progression.
