Knee Pain: Common Causes and When to See an Orthopaedic Doctor

Knee pain is one of the most common complaints that brings patients to an orthopaedic clinic. It can affect anyone -- from young athletes to elderly adults. Understanding what is causing your knee pain is the first step toward getting the right treatment.

Common Causes of Knee Pain by Age Group

Young Adults (18-35 years)

• Ligament injuries (ACL, MCL) -- Common in sports like cricket, football, and kabaddi
• Meniscus tears -- Twisting injuries to the knee's shock-absorbing cartilage
• Patellofemoral pain syndrome -- Pain around the kneecap, often from overuse or poor alignment
• Tendinitis -- Inflammation of tendons, common in runners and cyclists

Middle-Aged Adults (35-55 years)

• Early osteoarthritis -- Wear and tear of knee cartilage begins
• Overweight-related knee stress -- Extra weight puts enormous pressure on knees
• Meniscus degeneration -- Cartilage weakens and tears more easily with age
• Bursitis -- Inflammation of fluid-filled sacs around the knee joint

Older Adults (55+ years)

• Osteoarthritis -- The most common cause; cartilage wears away causing bone-on-bone friction
• Rheumatoid arthritis -- Autoimmune condition causing joint inflammation
• Osteoporosis-related issues -- Weak bones increase fracture risk
• Gout -- Uric acid crystal deposits in the joint causing sudden severe pain

Home Remedies for Knee Pain

For mild knee pain without any injury or swelling, you can try these measures at home:

• RICE method -- Rest, Ice (15-20 minutes), Compression (crepe bandage), Elevation
• Over-the-counter pain relief -- Paracetamol or topical diclofenac gel for short-term use
• Gentle exercises -- Straight leg raises, wall squats, and hamstring stretches
• Hot fomentation -- Warm compress for chronic stiffness (not for acute injuries or swelling)
• Weight management -- Losing even 5 kg can significantly reduce knee stress
• Proper footwear -- Avoid high heels and worn-out shoes; use cushioned soles

When to See an Orthopaedic Doctor

Home remedies are not enough when knee pain is persistent or getting worse. Consult an orthopaedic doctor if:

• Knee pain lasts more than 2 weeks despite home care
• You cannot fully bend or straighten your knee
• The knee is swollen, red, or warm to touch
• You heard a popping sound during an injury
• The knee gives way or feels unstable while walking or climbing stairs
• You have morning stiffness lasting more than 30 minutes
• Pain is waking you up at night
• You are limping or avoiding activities you used to enjoy
• There is visible deformity -- the leg looks bowed or knocked

Diagnostic Tests for Knee Pain

Your orthopaedic doctor will examine your knee and may recommend:

X-Ray

• First test ordered for most knee problems
• Shows bone alignment, joint space narrowing, fractures, and arthritis changes
• Quick, painless, and affordable

MRI (Magnetic Resonance Imaging)

• Provides detailed images of soft tissues -- ligaments, cartilage, meniscus
• Essential for diagnosing ACL tears, meniscus injuries, and cartilage damage
• No radiation involved

Blood Tests

• Ordered when rheumatoid arthritis, gout, or infection is suspected
• Common tests: RA factor, uric acid, ESR, CRP

Arthroscopy (Diagnostic)

• A tiny camera is inserted into the knee through a small incision
• Used when MRI findings are inconclusive
• Can treat certain problems during the same procedure

Treatment Options for Knee Pain

Non-Surgical Treatments

• Physiotherapy -- Strengthening exercises to support the knee joint
• Medications -- Anti-inflammatory drugs, cartilage supplements (glucosamine)
• Knee braces and supports -- Provide stability during daily activities
• Injections -- Corticosteroid injections for inflammation; hyaluronic acid (viscosupplementation) for lubrication
• PRP therapy -- Platelet-rich plasma injections to promote healing

Surgical Treatments

• Arthroscopic surgery -- Minimally invasive; for meniscus repair, loose body removal, ligament reconstruction
• ACL reconstruction -- Damaged ligament is replaced using a graft
• Osteotomy -- Bone is reshaped to shift weight away from the damaged part of the knee
• Partial knee replacement -- Only the damaged portion of the knee is replaced
• Total knee replacement -- The entire knee joint is replaced with an artificial joint; recommended for severe arthritis

Frequently Asked Questions

Is knee pain a normal part of ageing?

Some degree of knee stiffness with age is common, but persistent pain that limits your daily activities is not normal and should be evaluated. Early treatment can prevent further damage.

Can knee pain be cured without surgery?

Yes, in many cases. Mild to moderate arthritis, tendinitis, bursitis, and many soft tissue injuries respond well to physiotherapy, lifestyle changes, and medications. Surgery is considered only when conservative treatment fails.

When is knee replacement surgery recommended?

Knee replacement is recommended when arthritis is severe (Grade 3-4), pain is constant even at rest, daily activities like walking and climbing stairs have become very difficult, and non-surgical treatments have stopped working.

How long does recovery take after knee replacement?

Most patients start walking with support within 1-2 days after surgery. Normal walking without support typically returns in 4-6 weeks. Full recovery with return to all activities takes 3-6 months.

Does cracking or popping in the knee mean arthritis?

Not necessarily. Painless cracking or popping (crepitus) is very common and usually harmless. However, if the cracking is accompanied by pain, swelling, or stiffness, get it checked.

Can exercises worsen knee pain?

The wrong exercises can. Avoid deep squats, lunges with heavy weights, and running on hard surfaces if you have knee pain. Low-impact exercises like swimming, cycling, and straight leg raises are generally safe and beneficial.

Prevention Tips to Protect Your Knees

• Maintain a healthy weight -- Every extra kilogram adds approximately 4 kg of pressure on your knees
• Stay active -- Regular low-impact exercise keeps the joint flexible and muscles strong
• Warm up before exercise -- Always stretch before physical activity
• Wear proper shoes -- Especially during walking, running, or standing for long hours
• Strengthen your leg muscles -- Strong quadriceps and hamstrings protect the knee joint
• Use proper posture -- When sitting, avoid keeping knees bent at sharp angles for long periods
• Do not ignore injuries -- A small ligament tear today can become chronic instability tomorrow
