If you feel a dull, nagging ache around the front of your knee — especially when climbing stairs, squatting, sitting for long periods, or running — there is a good chance you are dealing with patellofemoral pain syndrome. It is one of the most common knee conditions we see at Jagriti Physiotherapy in Jaipur through our specialized knee physiotherapy services, and it affects a surprisingly wide range of people — from teenagers playing basketball to office workers who sit at a desk all day to middle-aged runners who have ramped up their training.
Most people who come in with this problem have been managing it for months. They have tried rest, maybe some painkiller gel, perhaps even reduced activity for a while — and the pain keeps coming back the moment they return to stairs or squatting. That pattern is completely typical of patellofemoral pain syndrome, and it happens because rest alone does not fix the underlying cause.
The good news is that PFPS responds very well to physiotherapy. The majority of patients — when treated with the right exercise programme and hands-on care — see significant improvement within weeks to months. This guide explains everything you need to know about the condition and how we treat it at our Jaipur clinic.
What is Patellofemoral Pain Syndrome?
Patellofemoral pain syndrome — often abbreviated to PFPS and sometimes called runner’s knee — is a condition characterised by pain at the front of the knee, around or behind the kneecap (patella).
To understand what goes wrong in PFPS, it helps to understand how the kneecap normally works. The patella sits in a groove at the lower end of the femur (thigh bone) and acts as a pulley for the quadriceps muscles, allowing the knee to extend powerfully. When everything is working properly, the kneecap glides smoothly up and down within this groove as the knee bends and straightens.
In patellofemoral pain syndrome, this smooth tracking is disrupted. The kneecap does not move correctly within its groove — it tilts, shifts slightly to one side, or presses unevenly against the underlying cartilage. Over time, this abnormal contact creates irritation, inflammation, and pain.
The disrupted tracking is almost always caused by muscle imbalances — either weakness in the muscles that are supposed to keep the kneecap aligned (particularly the VMO, a specific portion of the quadriceps) or tightness in the structures that are pulling it off track. And this is exactly why physiotherapy is so effective — because these are muscular and biomechanical problems, and muscles can be strengthened and retrained.
PFPS affects around 22.7% of the population and is the most common cause of anterior knee pain seen in outpatient clinics. It is particularly prevalent in young athletes, runners, gym-goers, and adolescents — though it can affect anyone at any age.

Who Gets PFPS? Common Causes in Jaipur Patients
There is rarely one single cause. Patellofemoral pain syndrome tends to develop from a combination of factors, often building up over weeks or months before becoming symptomatic.
Overuse and sudden increase in activity
This is probably the most common trigger we see in Jaipur. Someone starts running more than usual, begins training for a local race, or starts a new gym programme — and within a few weeks the front of the knee starts aching. The muscles have not had time to adapt to the increased load.
Weak VMO and quadriceps
The VMO (vastus medialis oblique) is the teardrop-shaped inner portion of the quadriceps. It is the primary muscle responsible for keeping the kneecap tracking correctly in its groove. When it is weak relative to the outer quad muscles, the kneecap is pulled slightly outward — leading to uneven pressure and pain.
Weak hip and glute muscles
This one surprises many patients. The hip abductors — particularly the gluteus medius — control the alignment of the femur during movement. When they are weak, the thigh rotates inward during walking, running, and squatting, which dramatically increases the load on the patellofemoral joint. Hip weakness is consistently found in patients with PFPS.
Tight muscles
A tight IT band pulls the kneecap laterally. Tight quadriceps and hamstrings increase the compressive force on the patellofemoral joint. Tight calf muscles alter foot mechanics, which affects how forces travel up through the knee.
Sitting habits
In Jaipur, prolonged sitting — whether at a desk, during long commutes, or in cross-legged positions during family gatherings or prayers — keeps the knee in a bent position that compresses the patellofemoral joint for extended periods. Many patients notice their pain is worst after getting up from a long seated position.
Age and gender
PFPS is more common in women than men — partly due to differences in hip and pelvic anatomy that create a wider Q-angle (the angle between the hip and the knee), which increases the tendency for the kneecap to track outward.
Symptoms of Patellofemoral Pain Syndrome
The symptoms of patellofemoral pain syndrome are fairly characteristic — once you know what to look for, they paint a fairly clear picture.
- Pain at the front of the knee, around or behind the kneecap. This is the defining feature. The pain is usually dull and aching rather than sharp. It may be diffuse — spread around the kneecap rather than in one precise spot.
- Pain that worsens with activity. Stairs — particularly going down — are consistently the worst trigger. Squatting, running, jumping, cycling, and kneeling all tend to provoke it.
- Pain after prolonged sitting. Sitting with the knee bent for long periods — in a car, at a desk, during a long meeting or a train journey — leads to increasing discomfort that eases when you stand and walk around. This is sometimes called the “movie sign” or “theatre sign” in clinical literature.
- A rubbing, grinding, or clicking sensation. Some patients feel or hear a grating under the kneecap when bending and straightening the knee. This is the patella moving across irritated or roughened cartilage.
- Occasional swelling. Mild swelling around the kneecap may occur, particularly after prolonged activity.
- Feeling of weakness or instability. Some patients describe the knee feeling unreliable — not a true giving way, but a sense of not fully trusting it under load.
Importantly, patellofemoral pain syndrome symptoms are often bilateral — both knees can be affected, though usually one is worse than the other.
How is PFPS Diagnosed?
One of the frustrations with patellofemoral pain syndrome is that it often does not show up clearly on imaging. An X-ray may look entirely normal. Even an MRI may not reveal obvious damage. This is because PFPS is fundamentally a functional problem — about how the kneecap moves — rather than a structural injury.
Diagnosis is primarily clinical, meaning it is based on the patient’s history and a physical examination. A skilled physiotherapist will ask about the location and nature of the pain, what makes it better or worse, when it started, and what activities you do regularly.
The physical examination includes several specific tests:
Clarke's test (patellar grind test)
The physiotherapist applies gentle pressure to the top of the kneecap while asking the patient to contract the quad. Pain or discomfort with this manoeuvre is a positive indicator of patellofemoral irritation.
Patellar tilt test
Assessing whether the kneecap is being pulled laterally by tight outer structures.
Single leg squat assessment
Watching how the knee tracks during a single leg squat is one of the most revealing tests. Inward collapse of the knee (valgus), hip drop, or kneecap deviation are all observable signs of the muscle imbalances driving the condition.
Quadriceps and hip strength testing
Measuring strength side to side helps quantify exactly which muscles need the most attention.
Imaging (X-ray or MRI) may be ordered to rule out other causes of anterior knee pain — such as Osgood-Schlatter disease in younger patients, patellar tendinopathy, or early osteoarthritis — but it is not always necessary for the diagnosis of PFPS itself.
Physiotherapy Treatment for Kneecap Pain
Physiotherapy is the primary and most effective treatment for patellofemoral pain syndrome. Research confirms that quadriceps and hip strengthening combined with stretching in a structured physiotherapy programme is the most effective approach — both for reducing pain and improving long-term function.
At Jagriti Physiotherapy in Jaipur, our treatment is built around three main pillars:
Taping and Bracing Techniques
Patellar taping is a useful tool in the early stages of PFPS management. The idea is to manually reposition the kneecap using strapping tape — shifting it slightly inward to reduce the abnormal lateral pressure that is causing pain. When applied correctly, many patients feel immediate pain relief during activities that were previously aggravating.
This is not a cure. Taping works by temporarily altering the mechanics while the underlying muscle weaknesses are being addressed through exercise. It allows patients to exercise with less pain in the early weeks — which means better engagement with the rehabilitation programme and faster progress.
McConnell taping technique is the most commonly used approach for PFPS. Kinesiology taping is also used by some physiotherapists as an adjunct. Both have their place depending on the individual patient.
Patellofemoral braces and knee sleeves are sometimes used for additional support during activity, though evidence suggests they work best as a complement to exercise rather than as a standalone solution.
VMO and Quadriceps Strengthening
The VMO — the inner, lower portion of the quadriceps — is almost universally weak or underactive in patients with PFPS. Reactivating and strengthening it is central to correcting the kneecap’s tracking pattern.
- Terminal knee extensions – Stand with a resistance band looped around a fixed point behind you and around the back of your knee. From a slightly bent knee position, straighten the knee fully against the band’s resistance, focusing on squeezing the inner quad at the end. This exercise specifically targets the VMO.
- VMO squats (narrow stance mini squats) – A narrower stance during squatting activates the VMO more than a wide stance. Keep the depth to 30 to 45 degrees, feet hip-width or slightly narrower, toes pointing forward. Focus on controlled descent and a strong inner quad contraction as you rise.
- Step-downs – Stand on a step with one foot. Slowly lower the other foot toward the floor in a controlled single-leg squat, then return to starting position. This is one of the most functional exercises for PFPS — it directly mimics stair descent, which is typically the most provocative activity for these patients. It is also a demanding exercise that requires adequate quad and hip strength before being introduced.
- Straight leg raises – Lying flat on the back, keeping the leg straight and tightening the quad before lifting. Excellent for building basic VMO activation without loading the joint.
Hip Strengthening for Kneecap Alignment
Hip strengthening is not optional in PFPS management — it is essential. Studies consistently show that patients with PFPS have significantly weaker hip abductors and external rotators than pain-free individuals, and that addressing this weakness reduces both pain and recurrence.
- Clamshells – Lying on your side, knees bent, feet together. Rotate the top knee upward like a clamshell opening, hold briefly, and lower with control. Targets the gluteus medius — the primary hip stabiliser.
- Side-lying hip abduction – Lying on your side, lift the top leg straight to about 30 to 40 degrees. Controlled, not swinging. Builds the lateral hip muscles that prevent femoral internal rotation during movement.
- Glute bridges – Lying on your back, push through the heels and lift the hips. Squeeze the glutes firmly at the top. One of the most effective glute exercises for PFPS, with excellent evidence behind it.
- Single-leg balance progressions – Standing on one leg, progressing from flat ground to a wobble board as strength improves. Trains the hip stabilisers in a dynamic, functional way — closely mimicking the demands of walking and running.
PFPS in Runners and Gym-Goers — Special Considerations
Runners are the group most commonly associated with patellofemoral pain syndrome — so much so that it is often called runner’s knee. But in Jaipur’s growing fitness culture, we are seeing it increasingly in gym-goers, CrossFit participants, and people who have recently started high-intensity training.
For runners, the most important factors are training load management and running mechanics. Increasing weekly mileage too rapidly is a primary driver — the general guideline is not to increase total mileage by more than 10% per week. Running cadence (step rate) also matters — a lower cadence means longer strides and more impact force per step, which increases patellofemoral load. Small adjustments to running form, combined with hip and quad strengthening, can make a dramatic difference.
For gym-goers, the culprits are usually heavy squats performed with poor form, leg press machine work, and high-rep lunges done before adequate hip strength is established. The gym does not cause PFPS — but doing the wrong exercises too heavily before the supporting muscles are ready does.
For both groups, a graduated return-to-activity plan — where training load is temporarily reduced, then carefully rebuilt — is a key part of treatment. Going from zero to full training the moment the pain settles is a very reliable way to relapse.
Online Physiotherapy for Patellofemoral Pain
Patellofemoral pain syndrome is actually one of the conditions that lends itself quite well to online physiotherapy, particularly once a diagnosis has been established. The exercise-based nature of treatment means that a significant portion of the programme can be guided effectively through video consultations.
Dr. Deepesh Nainani at Jagriti Physiotherapy offers online consultations for PFPS patients across Jaipur and beyond. During an online session, your symptoms will be assessed through a guided movement evaluation, a personalised exercise programme will be built around your specific muscle weaknesses and activity goals, and progress will be monitored through regular follow-up sessions.
For patients who cannot visit our Shyam Nagar, Sodala clinic in person — or who are in the later stages of rehabilitation and primarily exercising at home — online physiotherapy is a practical, effective option.
FAQs — Patellofemoral Pain Syndrome
1. What is patellofemoral pain syndrome?
Ans: Patellofemoral pain syndrome (PFPS) is a condition causing pain at the front of the knee, around or behind the kneecap. It occurs when the kneecap does not track smoothly in its groove on the thigh bone, creating abnormal pressure and irritation. It is the most common cause of anterior knee pain and is particularly common in runners, young athletes, and people who sit for long periods.
2. What are the main symptoms of patellofemoral pain syndrome?
Ans: The hallmark symptoms are a dull aching pain around the front of the knee, pain that worsens with stairs (especially going down), squatting, running, and prolonged sitting with the knee bent. A grinding or clicking sensation under the kneecap during movement is also common. Symptoms often come on gradually and worsen with activity.
3. How is patellofemoral pain syndrome diagnosed?
Ans: Diagnosis is primarily clinical — based on symptoms and a physical examination. Tests like Clarke’s test, patellar tilt assessment, and single-leg squat observation help identify the kneecap tracking problem and the muscle imbalances driving it. X-ray or MRI may be used to rule out other conditions but are often normal in PFPS.
4. What is the best treatment for patellofemoral pain syndrome?
Ans: Physiotherapy is the most effective treatment. A structured programme combining VMO and quadriceps strengthening, hip and glute strengthening, stretching, and activity modification has the strongest evidence. Patellar taping can provide short-term pain relief to support early rehabilitation. Surgery is rarely needed.
5. What are the best exercises for patellofemoral pain syndrome?
Ans: The most evidence-based exercises include terminal knee extensions and VMO squats (for quadriceps and VMO activation), clamshells and glute bridges (for hip strengthening), single-leg step-downs (for functional strength), and quadriceps and IT band stretches. The specific programme should be tailored by a physiotherapist to your individual weaknesses.
6. How long does patellofemoral pain syndrome recovery take?
Ans: Mild to moderate cases typically improve within 4 to 8 weeks of consistent physiotherapy. More persistent cases — particularly those that have been present for several months — can take 3 to 6 months to fully resolve. An important caveat: around 50% of people with PFPS report ongoing symptoms after a year if the underlying muscle imbalances are not adequately addressed. Early, consistent treatment significantly reduces the risk of it becoming a long-term problem.
7. Can patellofemoral pain syndrome heal on its own?
Ans: Mild cases sometimes settle with rest and activity modification. But because PFPS is driven by muscle weakness and biomechanical imbalance, it tends to return as soon as activity resumes — unless the underlying causes have been fixed. Rest treats the symptom. Physiotherapy treats the cause.
8. Is running safe with patellofemoral pain syndrome?
Ans: Running through significant pain is not advisable — it perpetuates the irritation and slows recovery. However, complete rest from running is also not always necessary or helpful. A graduated return to running — with reduced volume and intensity, alongside the physiotherapy programme — is usually the right approach. Your physiotherapist will guide you on safe activity levels for your specific situation.
9. What is the patellofemoral pain syndrome test used by physiotherapists?
Ans: The most commonly used clinical test is Clarke’s test (patellar grind test), where pressure is applied to the kneecap during a quad contraction to reproduce pain. The patellar tilt test, glide test, and single-leg squat assessment are also used. Together, these give a clear clinical picture of whether PFPS is present and what is driving it.
10. Does patellofemoral pain syndrome require surgery?
Ans: Very rarely. The vast majority of PFPS cases resolve with conservative physiotherapy management. Surgery — typically arthroscopic — is only considered in very specific cases where conservative treatment has been thoroughly attempted over a significant period without adequate improvement. It is not a first or second line option.
