Knee Pain After 40: What’s Normal and What’s Not?

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

Turning 40 marks a new phase of life, one filled with wisdom, experience, and sometimes, unexpected joint pains. Among them, knee pain is one of the most common complaints. But how do you know if it’s just age catching up or a sign of something more serious? Let’s understand the difference between normal age-related changes and red flags that need medical attention.

Knee pain after 40 is not just a sign of aging, it’s your body’s way of asking for attention. With timely care, you can stay active and pain-free at any age.

What’s Normal Knee Pain After 40?

As we age, our joints naturally experience some wear and tear. The cartilage that cushions the bones may begin to thin, leading to occasional stiffness or mild pain — especially after long walks, climbing stairs, or sitting for long periods.

Common normal symptoms include:

• Mild stiffness after rest

• Slight swelling after activity

• Occasional discomfort while bending or squatting

• Pain that improves with rest and light stretching

These symptoms usually respond well to simple lifestyle adjustments, such as:

• Regular low-impact exercises like swimming or cycling

• Maintaining a healthy weight

• Strengthening thigh and core muscles

• Using ergonomic footwear

What’s Not Normal? When to See a Doctor

Persistent or worsening knee pain should never be ignored. It could indicate underlying orthopedic issues that require professional care.

Red flags include:

• Pain lasting more than a few weeks

• Swelling or warmth around the joint

• Popping or grinding sounds while moving

• Pain that interrupts sleep

• Inability to bend or straighten the knee fully

These symptoms could point to conditions such as:

• Osteoarthritis – gradual cartilage degeneration

• Meniscus tears – due to twisting injuries or strain

• Ligament injuries – common during sports or sudden movements

• Inflammatory arthritis – involving autoimmune causes

At this stage, consulting an orthopedic specialist like Dr. Vinayaraj M. Kelagadi at Kossin Care, Bangalore, helps in early diagnosis and effective treatment.

Treatment and Care Options

Dr. Vinayaraj emphasizes that early detection and personalized treatment can help prevent long-term joint damage.Treatment may include:

• Physiotherapy to improve joint strength and mobility

• Medications to reduce pain and inflammation

• Injections (Hyaluronic acid or PRP) for cartilage support

• Minimally invasive surgery if structural issues are present

• Knee replacement only in advanced cases

Preventing Knee Pain After 40

• Keep your weight in check – every extra kilo adds pressure on the knees.

• Stay active but balanced – avoid overstraining joints.

• Practice good posture when sitting and walking.

• Include calcium, vitamin D, and omega-3s in your diet.

• Regular check-ups with an orthopedic doctor to monitor joint health.
