Very few things wear you down as quietly as a knee that hurts. It changes how you climb stairs, how you sit through a prayer or a meeting, whether you agree to that evening walk. Most people I meet in my clinic in Punjabi Bagh have been living with it for months — pushing through, rubbing on a balm, waiting for it to settle on its own. So let me say this early: knee pain is common, it is usually treatable, and in most cases it does not mean you are heading for surgery.

Quick answer

Knee pain is a symptom, not a diagnosis. Its most common causes are osteoarthritis, meniscus and ligament injuries, patellofemoral pain, tendinitis and bursitis. The great majority can be treated without surgery using physiotherapy, image-guided injections, regenerative medicine (such as PRP) and genicular nerve radiofrequency ablation. The single most important step is an accurate diagnosis by a knee pain specialist, because the right treatment depends entirely on the correct cause.

I'm Dr. Titiksha Goyal, an interventional pain specialist trained at AIIMS New Delhi, and this is the guide I wish every patient could read before their first appointment. My aim here is not to sell you a procedure. It is to help you understand your own knee well enough to make a calm, informed decision — and to recognise the few situations where you should stop reading and see a doctor today.

How Your Knee Actually Works (In Plain Terms)

Think of the knee as a hinge where three bones meet — the thigh bone (femur), the shin bone (tibia) and the kneecap (patella). Between them sits smooth cartilage that lets the joint glide, and two rubbery cushions called menisci that absorb shock. Strong ropes called ligaments (the ACL, PCL, MCL and LCL) hold everything stable, while tendons connect the powerful thigh muscles to the bones so you can straighten and bend.

Wrapped around the whole joint is a capsule richly supplied with tiny pain-sensing nerves — including a set called the genicular nerves. Here is the key idea to hold on to: pain doesn't come from cartilage itself (cartilage has no nerves). It comes from these surrounding structures — the bone lining, the capsule, the ligaments, the tendons and their nerves. That's exactly why treatments aimed at those pain-carrying nerves, like genicular nerve radiofrequency ablation, can work so well even when the cartilage is worn.

Common Causes of Knee Pain

When someone says "my knee hurts," an experienced pain physician is already running through a mental list. Knee pain usually falls into a handful of recognisable patterns. Here are the ones I see most often at our pain clinic in Punjabi Bagh:

1

Knee Osteoarthritis

Gradual wearing of the joint cartilage — the leading cause of chronic knee pain after age 45. A dull ache that worsens with stairs, squatting and long walks, with brief morning stiffness. We cover its treatment in depth here.

2

Meniscus Tears

Damage to the shock-absorbing cartilage cushion, from a twist or from age-related wear. Causes catching, locking or a popping feeling, with pain along the inner or outer joint line.

3

Ligament Injuries

Tears of the ACL, PCL, MCL or LCL — usually a sports injury, sudden twist or fall. Often with swelling and a sense that the knee will "give way."

4

Patellofemoral Pain

"Runner's knee" — pain around or behind the kneecap that worsens with prolonged sitting, squatting or stairs. Common in younger, active people.

5

Tendinitis

Inflammation of the patellar or quadriceps tendon from overuse ("jumper's knee"). Pain just above or below the kneecap, worse after activity.

6

Bursitis

Inflammation of the fluid-filled cushions of the knee — from kneeling ("housemaid's knee") or pes anserine bursitis causing pain just below the inner knee.

7

Inflammatory & Crystal Arthritis

Rheumatoid arthritis, gout or pseudogout — knee pain with warmth, marked swelling and stiffness. These need a different treatment pathway, so they must be identified.

8

Referred Pain

Sometimes the knee is normal and the pain is referred from the hip or lower back. This is why a good examination looks at the whole limb, not just the knee.

Notice how different these are. Gout is treated with medication; a complete ACL rupture in a young athlete may need surgery; osteoarthritis responds beautifully to a graded, non-surgical plan. This is the entire reason I resist the urge to treat "knee pain" as one thing — and why a proper consultation matters more than any single injection.

Symptoms and What They Mean

Your symptoms are clues. Before any scan, the story of your pain already points towards the cause.

Common knee symptoms — and what they often suggest

  • Pain on stairs and squatting, morning stiffness under 30 minutes — typically osteoarthritis.
  • Catching, locking or the knee "getting stuck" — suggests a meniscus problem or a loose fragment.
  • The knee "giving way" or feeling unstable — points to ligament or muscle weakness.
  • Swelling within hours of an injury — suggests bleeding inside the joint (often a ligament or fracture) and needs prompt review.
  • Pain behind the kneecap, worse after sitting — patellofemoral pain.
  • Hot, red, very swollen knee with fever — could be infection or gout; this is urgent.
  • Night pain and stiffness lasting over an hour each morning — raises the possibility of inflammatory arthritis.

Red Flags — When to Seek Urgent Medical Care

Most knee pain can wait for a routine appointment. A few situations should not. Please don't wait these out.

See a doctor urgently if you have

  • A hot, red, swollen knee with fever — possible joint infection (septic arthritis) needs same-day care.
  • A knee that cannot bear any weight after an injury, or looks deformed — a possible fracture or dislocation.
  • Sudden severe swelling within hours of trauma.
  • Calf pain, redness and swelling below the knee, especially after travel or surgery — to rule out a clot (DVT).
  • Numbness, a cold or pale foot, or inability to move the ankle — possible nerve or blood-vessel involvement.

If any of these apply, go to an emergency department rather than booking a routine appointment.

What Happens If You Ignore Knee Pain

I understand the temptation to wait — most of us are busy, and pain that comes and goes feels less urgent. But knee pain tends to set up a cycle. It hurts, so you move less. Moving less weakens the thigh muscles (the quadriceps), which are the knee's natural shock absorbers. A weaker knee is a more painful knee, so you move even less, often gain weight, and the joint loads unfavourably. Left long enough, mild, very treatable problems can progress to stiffer joints and more advanced arthritis. The good news is that this cycle can usually be reversed — and the earlier we start, the easier it is.

How We Find the Real Cause of Your Knee Pain

Patients often ask, nervously, "What will happen at my first visit? Will it be painful?" A consultation is simply a conversation and a careful examination — nothing invasive on day one. Here is what it actually involves:

1. Your story

When the pain started, what makes it better or worse, how it affects your day, sleep and work. This alone narrows the diagnosis considerably.

2. Hands-on examination

I assess your walking pattern, range of movement, exactly where it is tender, ligament stability and muscle strength — and check the hip and back, since these can refer pain to the knee.

3. Targeted imaging

Weight-bearing X-rays to grade arthritis, and ultrasound or MRI when a ligament, meniscus or tendon problem is suspected. We order scans to answer a question, not by reflex.

4. Diagnostic block (when needed)

In select cases, a small numbing injection around a specific nerve or structure confirms it is the true source of pain before we commit to longer-lasting treatment.

By the end of that visit, you should leave with two things you probably didn't arrive with: a clear name for what is wrong, and a plan written around your knee and your life — not a generic prescription.

The Step-by-Step Treatment Ladder

Good pain medicine is conservative first and escalates only as far as needed. I think of knee treatment as a ladder — we start on the lowest rung that can realistically help you, and climb only if we must.

Foundations for everyone

Physiotherapy and quadriceps strengthening, weight management, activity modification, suitable footwear, and short-term anti-inflammatory medication where safe. For early problems this is often enough.

Image-guided injections

Corticosteroid for inflammatory flare-ups, viscosupplementation (hyaluronic acid) for lubrication, and regenerative options such as PRP for degenerative joints — all placed accurately under ultrasound guidance.

Genicular nerve RFA

For persistent osteoarthritis pain that no longer responds to injections, we calm the specific nerves carrying pain from the knee — a powerful way to delay or avoid surgery.

Surgical referral

For the minority — complete ligament ruptures, mechanically locking meniscus tears, or advanced bone-on-bone arthritis — we refer to a trusted orthopaedic surgeon as part of a coordinated plan.

Interventional Pain Procedures That Help Knee Pain

"Interventional" simply means targeted, image-guided treatments delivered precisely to the source of pain, usually through a needle rather than an incision. In plain terms: we treat the exact spot that hurts, watching on a screen as we do it, and you go home the same day. These are the workhorses for knee pain.

Image-guided joint and soft-tissue injections

A steroid injection can settle an angry, inflamed knee and buy a valuable window to rebuild strength through physiotherapy. Done under ultrasound, the medicine reaches exactly where it's needed — which matters, because studies show a meaningful proportion of "blind" knee injections miss the joint space. Precision is not a luxury here; it's the difference between a treatment that works and one that doesn't.

Viscosupplementation (hyaluronic acid)

This restores some of the natural lubricating fluid the joint loses with arthritis. Think of it as re-oiling a stiff hinge. It can ease friction and improve comfortable movement, most usefully in mild to moderate osteoarthritis.

Regenerative medicine — PRP and prolotherapy

Regenerative treatments aim to support the joint's own repair environment rather than just mask pain. PRP (platelet-rich plasma) uses a small sample of your own blood, concentrated to its healing platelets and injected back into the joint. Because it comes from you, there is no risk of rejection or allergy. Prolotherapy is useful where loose or lax ligaments make a knee unstable. These work best in early-to-moderate disease and are covered in detail, alongside the evidence, in our knee osteoarthritis guide.

Genicular nerve radiofrequency ablation (RFA)

This is one of the most valuable tools we have for stubborn knee pain, particularly from osteoarthritis in patients who want to avoid or delay a knee replacement. The genicular nerves carry pain signals from the knee; RFA uses controlled radiofrequency heat to quiet them, without weakening the leg. Relief can last many months, and the procedure can be safely repeated.

Why the technique matters

Not all genicular RFA is equal. The conventional method uses X-ray landmarks and targets only three nerves. At PainClinix we use an ultrasound-guided, anatomy-based technique to an international standard, targeting more of the nerves that actually supply the knee — which aims for more complete and longer-lasting relief.

Which Treatments Actually Work — and Which Are Myths

There is a lot of noise around knee pain. Let me be straight with you about what the evidence — and years of clinic experience — actually support.

Claim you may have heard The honest picture
"Walking and exercise will wear my knee out faster." Myth. Appropriate exercise and quadriceps strengthening are among the most effective, evidence-backed treatments for knee osteoarthritis. Rest weakens the knee.
"Painkillers are the only option until I need a replacement." Myth. Between tablets and surgery lies a whole ladder of injections, regenerative treatment and genicular RFA.
"Glucosamine supplements will rebuild my cartilage." Overstated. Evidence is weak and inconsistent. They are unlikely to harm, but they are not a cure.
"An MRI is always needed for knee pain." Not true. Many diagnoses are clinical. Scans are ordered when they will change the plan — and MRIs often show harmless age-related changes that can mislead.
"Steroid injections are dangerous and ruin the joint." Context matters. Occasional, well-placed steroid injections are safe and useful for flares; the concern is only with frequent, repeated injections.
"Genicular RFA is unproven." Outdated. It is increasingly supported for osteoarthritis knee pain and recommended in interventional pain practice worldwide.

Can Surgery Be Avoided? And When Is It Truly Needed?

This is the question behind almost every consultation, so let me answer it plainly. For most people with knee osteoarthritis and many soft-tissue problems, yes — surgery can often be delayed for years or avoided altogether with a well-run non-surgical plan. That is precisely the space an interventional pain specialist works in.

But I will never talk you out of surgery you genuinely need. A knee replacement is the right answer for advanced, bone-on-bone arthritis that no longer responds to anything else, and prompt surgery matters for a complete ACL rupture in an active person or a meniscus that is mechanically locking the joint. Honest medicine means knowing both when to intervene and when to refer — and I would rather send you to a surgeon at the right time than have you suffer needlessly or undergo an operation too soon.

Doctor's advice

If you take one thing from this guide, let it be this: don't wait for the pain to become severe before seeking help, and don't accept "learn to live with it" as your only option. Knees respond best to early, accurate, layered treatment — and the strongest results come from combining a precise procedure with the unglamorous work of rehabilitation. Fix the pain, then rebuild the knee.

Why Choose an Interventional Pain Specialist at PainClinix

You have a choice about who treats your knee, so here is an honest account of why patients across Delhi NCR come to us — and why it might be right for you too.

Key takeaways

  • Knee pain is a symptom with many causes — accurate diagnosis comes before treatment.
  • Osteoarthritis is the most common cause after 45; ligament, meniscus and tendon problems dominate in younger, active people.
  • Most knee pain can be treated without surgery.
  • Genicular nerve RFA and regenerative medicine (PRP) are powerful, minimally invasive options — and technique quality matters.
  • A few red-flag situations (hot swollen knee with fever, inability to bear weight, suspected clot) need urgent care.
  • Rehabilitation makes relief last; a procedure alone is only half the job.

Summary

Knee pain rarely has a single cause, and it rarely has a single fix. Understanding whether you are dealing with osteoarthritis, a meniscus or ligament injury, tendinitis or something inflammatory is what makes treatment work. For the large majority of patients, a stepwise, image-guided, non-surgical plan — strengthening the knee, settling inflammation, and where needed calming the pain nerves with genicular RFA or supporting the joint with regenerative medicine — brings real, lasting relief and keeps surgery on the shelf. If your knee has been holding you back, it deserves a proper look.

Frequently Asked Questions About Knee Pain

What is the most common cause of knee pain?

In adults over 40 it is osteoarthritis; in younger, active people it is ligament injuries, meniscus tears, patellofemoral pain and tendinitis. Because treatment differs completely, the cause must be identified first.

Can knee pain be cured without surgery?

Most knee pain can be effectively managed — and often resolved — without surgery, using physiotherapy, image-guided injections, regenerative medicine and genicular nerve RFA. Surgery is needed only for a minority of cases.

When should I worry about knee pain?

Seek urgent care for a hot, swollen knee with fever, inability to bear weight after injury, a visibly deformed knee, or calf swelling suggesting a clot. Otherwise, see a specialist if pain lasts beyond 2–3 weeks or limits daily life.

What kind of doctor should I see for knee pain?

For non-surgical treatment, an interventional pain specialist is ideal — they diagnose the source and offer image-guided injections and nerve procedures. If structural surgery is required, they will coordinate an orthopaedic referral.

Is walking good or bad for knee pain?

For most knee pain, including osteoarthritis, appropriate walking and strengthening are beneficial. Prolonged rest weakens the muscles that protect the knee. The type and amount should be tailored to your condition.

Does knee pain always mean arthritis?

No. Arthritis is common but many other conditions cause knee pain. It should be confirmed by examination and X-ray, not assumed.

What is genicular nerve radiofrequency ablation?

A minimally invasive procedure that uses controlled heat to calm the genicular nerves carrying pain from the knee. It relieves pain without weakening the leg and is especially useful for osteoarthritis pain that hasn't responded to injections.

How long does genicular RFA relief last?

It varies, but relief commonly lasts several months to a year or more. Because nerves slowly regenerate, the procedure can be repeated safely if pain returns.

Does PRP therapy work for knee pain?

PRP can reduce pain and improve function in early-to-moderate osteoarthritis and some tendon or ligament injuries. It works best combined with rehabilitation and is not a substitute for surgery in advanced arthritis.

Are steroid injections in the knee safe?

Occasional, well-placed steroid injections are safe and helpful for inflammatory flares. The concern is only with frequent, repeated injections over time.

What is the best treatment for knee osteoarthritis?

A combination approach: strengthening and weight management as a foundation, plus injections, regenerative medicine or genicular RFA as needed. Our dedicated osteoarthritis guide explains each option.

Why does my knee hurt when climbing stairs?

Stair pain commonly points to osteoarthritis or patellofemoral (kneecap) pain, because stairs load these areas heavily. An examination can distinguish the two.

Why does my knee hurt at night?

Night pain can occur in advanced osteoarthritis and in inflammatory arthritis. Persistent night pain deserves evaluation, as it can indicate the problem is progressing.

Can losing weight reduce knee pain?

Yes. Because the knee experiences several times your body weight with each step, even modest weight loss can meaningfully reduce load and pain.

Is knee pain in young adults serious?

Usually it reflects patellofemoral pain, tendinitis or sports injuries rather than arthritis. Most respond well to targeted rehabilitation and, when needed, image-guided treatment.

How is the cause of knee pain diagnosed?

Through your history, a hands-on examination, targeted imaging (X-ray, ultrasound or MRI) and, in select cases, a diagnostic nerve or joint block to confirm the pain source.

Will treatment for knee pain be painful?

The consultation and examination are not invasive. Procedures are done under local anaesthesia with image guidance; most patients report mild pressure rather than pain and go home the same day.

Can knee pain go away on its own?

Minor strains often settle with rest and time. Pain that persists beyond a few weeks, recurs, or limits activity should be evaluated rather than ignored.
