Causes
People with patellofemoral pain syndrome will often feel generalised pain around the knee, usually under and around the kneecap. The pain can get worse with activities such as sports, walking, climbing stairs, or after sitting for a long time with the knees bent. Pain may be present in one or both knees.
Symptoms
strengthening the muscles supporting the knee and hip. The key is to strengthen the muscles without increasing the pressure in the patellofemoral joint. Examples of exercises that reduce the pressure in the PFJ include straight leg raise, side-lying leg raise, clamshell, hip bridges, and squats. improving the flexibility of the muscles in the leg.
Prevention
Patellofemoral pain syndrome (PFPS) is a problem with pain that feels like it is mainly on the front of the knee, specifically on the underside of or somewhere around the edges of the kneecap. In average cases, the pain is not severe and the problem often goes away with basic physical therapy.
Complications
Typically, surgery is not required for patellofemoral pain syndrome, as there is no specific structural damage that is causing your pain. If other signs and symptoms exist such as direct trauma to the knee or persistent patellar dislocations, a referral for surgical consultation may be indicated.

Does patellofemoral syndrome show up on xray?
Imaging of the patellofemoral joint begins with standard radiographs of the knee, including anteroposterior, lateral, and axial views. The anteroposterior view is the least valuable in evaluating the patellofemoral compartment, but it can demonstrate multipartite patellae as well as gross patella alta or baja.
Will a knee brace help patellofemoral syndrome?
Runner's knee and patellofemoral pain syndrome can occur when your kneecap has veered off the patellar groove. “This issue is often helped by a strap-style brace,” Minnis says. He explains that “the strap helps compress the patellar tendon and aims to alleviate stress on the tendon.”

You may experience difficulty walking down stairs or staying upright if you are suffering from dizziness, inner ear issues, or migraine, for example.
Inner Knee Pain Going Down Stairs
Cartilage breakdown is one of the hallmarks of osteoarthritis (OA), which causes your bones to grind together in your joints. When you put pressure on your joint while walking, climbing, or sitting in a chair, you may have osteoarthritis.
Knee Pain Walking Down Stairs After Running
Pain under and around the knee is caused by the painful Patellofemoral pain syndrome. Walking, kneeling, squatting, going up or down stairs, or running are all common causes of pain. It could also occur after sitting for an extended period of time on a bent knee, such as when going on a long car ride or watching a movie.

This is typically due to a loose body or a torn cartilage flap in the joint. The knee may also be unstable as a result of a ligament tear or a torn ligament.
Knee Pain Down Stairs Meniscus
A condition that causes normal knee movement to be restricted can make it difficult for patients to climb stairs or take the stairs in their wheelchairs or automobiles. When you have pain in your knee, your brain shuts down the thigh muscles, causing you to feel as if you are giving way.
Knee Pain
There are many possible causes of knee pain. Some common causes include arthritis, bursitis, and tendinitis. Injury, overuse, and obesity are also common causes of knee pain. Treatment for knee pain depends on the underlying cause. Sometimes, rest, ice, and over-the-counter pain relievers are enough to relieve knee pain.
What is patellofemoral pain syndrome?
Patellofemoral pain syndrome can be stubborn and slow to improve. The good news is that it almost always eventually goes away and almost never requires surgery. Being patient is key. —Dr. Benjamin Schwartz
What triggers pain in the body?
High-impact activity (such as running or jumping) triggers pain.
What is the pain around the knee called?
Patellofemoral pain syndrome is pain around your kneecap. (The kneecap is also called the patella.) Sometimes it is called “runner’s knee.” Athletes tend to get it. But anyone can get it from everyday activity that engages the knee. Climbing stairs, sitting for long periods of time, and squatting can make it worse. Often it heals after rest and ice.
Can knee flexion cause pain?
The further you bend the knee, the tighter the kneecap gets pushed up against the femur (thigh) bone. When the knee is in deep flexion, the force on it can be up to 7 times higher than your body weight! It’s very common for people with patellofemoral pain syndrome to say that they recently started working out more—especially squats, lunges, and leg presses. While these are not dangerous, they can contribute to developing pain at the front of the knee. —Dr. Schwartz
Can you get patellofemoral pain from over exercising?
Patellofemoral pain syndrome can happen from over exercising but it's treatable and easy to prevent.
Do patellofemoral pains fade?
It’s not entirely clear why, but many people appear to “outgrow” patellofemoral pain syndrome. Their symptoms fade and eventually disappear in early to mid-adulthood. Ironically, while many musculoskeletal conditions become worse with age, patellofemoral pain syndrome actually tends to disappear. —Dr. Schwartz
How to treat patellofemoral syndrome?
Patellofemoral syndrome treatment is usually conservative and targeted at pain reduction, improved patellar tracking, and return to their previous level of function. The treatments of the patellofemoral syndrome are divided into 2 main sections, the acute and the recovery phase. The acute phase involves activity modification, NSAID use, and other conservative modalities such as ice. NSAIDs, specifically naproxen, have been shown to decreased overall pain when compared to aspirin and placebo; however, they are usually not recommended as a long-term treatment.[17] Other modalities such as the therapeutic US and electrical stimulation have not been shown to improve symptoms. [18][19]After the acute phase of treatment, the patient enters the recovery phase, which tries to correct the issue that most likely led to the development of the condition. The combination of knee and hip exercises to increase lower extremity strength, mobility, and function is the most effective intervention.[20] If the patient experiences pain with exercises, then adjunct therapy can be used. This includes patellar taping. Patellar taping has been shown to decrease overall pain when used in conjunction with physical therapy when compared to physical therapy alone.[21] However, in patients with a larger BMI, taping is less effective.[22] Therapy should be patient-specific and tailored to correct the dysfunction present. Referral to orthopedic surgery is not recommended and is considered a treatment of last resort.[23] Non-operative therapy should be pursued for 24 months before operative interventions are considered. [24]
What are the components of patellofemoral joint function?
The patellofemoral joint function relies on a complex interaction between static and dynamic structures involving the entire lower extremity as the patella tracks in the trochlea. Static components include leg length discrepancies, abnormal foot morphology, hamstring and hip musculature tightness, angular or rotational deformities, and trochlea morphologies. Dynamic components include muscle weakness, ground reaction forces, and insufficient or excessive foot pronation. Studies involving malalignment that potentially contribute to PFS are conflicting with no clear consensus, likely secondary to its multifactorial nature. Multiple studies have concluded that hip abductor weakness may play a major role.[4] Another study looking at female runners pointed to hip biomechanics as a cause, finding that greater hip adduction angles were associated with an increased risk for the development of PFS.[5] Though multiple studies have shown an association between hip abductor weakness, others have not been able to show a relationship and, in other cases, have shown an increased hip abduction strength to be the cause. [6]
What is the most common cause of anterior knee pain?
It is a diagnosis of exclusion once another intra-articular and peripatellar pathology has been ruled out. Pain is often located behind or around the patella and aggravated by loading a flexed knee joint. It is one of the most common causes of knee pain seen by clinicians. Studies have shown that up to two-thirds of patients can be successfully treated with a proper rehabilitation protocol. This activity will highlight the role of the interprofessional team in the evaluation and management of patients with patellofemoral syndrome.
What is PFS in a patient?
PFS is considered a diagnosis of exclusion once intraarticular or peripatellar pathologies are ruled out. The majority of patients with PFS experience a resolution of symptoms with conservative treatments, though in some rare cases may be resistant to therapies and be persistent for years.
What are the complications of PFS?
One complication from PFS includes the development of patellofemoral osteoarthritis secondary to the inadequate tracking of the patella, which may lead to chronic pain. Another complication is that some patients must stop activities that they previously enjoyed due to that activity causing them pain.
What is the differential diagnosis for PFS?
The differential diagnosis for a patient with PFS is quite broad and can be divided into 6 anatomic areas, as discussed earlier. These include patellofemoral OA, Osgood Schlatter's disease, plica, bursitis (prepatellar or Hoffa's), Saphenous neuritis, quadriceps tendinopathy, patellar tendinopathy, or referred pain from hip or back. Due to the broad differential, the clinician must perform a thorough history and physical exam to recognize certain risk factors and effectively treat the patient.
Can PFS cause malalignment?
Many patients with PFS do not demonstrate any signs of malalignment. Instead, during careful interviewing, overload of the patellofemoral joint is often described, which can lead to the development of PFS.[7] Studies have been performed showing that an increased workload on the joint such as miles ran/volume of work, correlates to the development of PFS, and patients usually state that pain began during a period of increased activity. [8][9] Risk factors that can lead to overload, thus increasing the risk of PFS, include prior fitness level, prior exercise regimen, and BMI >25. [10]
What is PFPS in knee pain?
The patellofemoral pain syndrome (PFPS) is a possible cause for anterior knee pain, which predominantly affects young female patients without any structural changes such as increased Q-angle or significant chondral damage. This literature review has shown that PFPS development is probably multifactorial with various functional disorders of the lower extremity. Biomechanical studies described patellar maltracking and dynamic valgus in PFPS patients (functional malalignment). Causes for the dynamic valgus may be decreased strength of the hip abductors or abnormal rear-foot eversion with pes pronatus valgus. PFPS is further associated with vastus medialis/vastus lateralis dysbalance, hamstring tightness or iliotibial tract tightness. The literature provides evidence for a multimodal non-operative therapy concept with short-term use of NSAIDs, short-term use of a medially directed tape and exercise programmes with the inclusion of the lower extremity, and hip and trunk muscles. There is also evidence for the use of patellar braces and foot orthosis. A randomized controlled trial has shown that arthroscopy is not the treatment of choice for treatment of PFPS without any structural changes. Patients with anterior knee pain have to be examined carefully with regard to functional causes for a PFPS. The treatment of PFPS patients is non-operative and should address the functional causes.
What causes a functional valgus?
Cause for functional or dynamic valgus can be internal rotation of the femur, the tibia or both. Internal rotation of the femur might be the result of weakness of the hip abductors; internal rotation of the tibia might arise from rear-foot eversion or pes pronatus. Functional valgus may lead to lateral patella maltracking
What causes internal rotation of the tibia?
An internal rotation of the tibia can also be caused by rear-foot eversion [42, 52] (Figs. 2, ,33).
What are the abnormalities of the navicular bone in high school students with PFPS?
[44] also could demonstrate abnormalities of the navicular bone in high school students with PFPS such as increased navicular drop, navicular drift and dorsiflexion.
Does patella maltracking affect PFPS?
Pal et al. [50] have demonstrated that “patella maltracking” in patients with PFPS correlates with a delayed activation of the M. vastus medialis . An imbalance in the activation of the M. vastus medialis obliquus and M. vastus lateralis was also shown by Cowan et al. [19]. In patients with a PFPS, the M. vastus lateralis was earlier activated than the M. vastus medialis obliquus when patients climbed downstairs and upstairs. In the control group that imbalance did not exist. These findings were supported by several other studies [15, 16, 74]. Patients with patellofemoral problems exhibited atrophy of the vastus medialis obliquus [49].
Does maltracking affect patella?
Recent studies, however, show that maltracking of the patella probably plays a key role. Draper et al. [24] for example have demonstrated by dynamic MRI that patients with a PFPS squat with increased lateralization and increased lateral tilt of the patella. Witvrouw et al. [74] showed that a hypermobile patella had a significant correlation with the incidence of patellofemoral pain.
Is PFPS multifactorial?
The pathogenesis of PFPS is multifactorial with various functional disorders of the lower extremity to be involved [8].
What is the most common cause of anterior knee pain?
Patellofemoral pain syndrome (PFPS) is one of the most common causes of anterior knee pain encountered in the outpatient setting in adolescents and adults younger than 60 years. The incidence in the United States is between 3% and 6%.
How to treat PFPS?
Treatment of PFPS includes rest, a short course of nonsteroidal anti-inflammatory drugs, and physical therapy directed at strengthening the hip flexor, trunk, and knee muscle groups. Patellar kinesiotaping may provide additional short-term pain relief; however, evidence is insufficient to support its routine use.
Does PFPS hurt when sitting?
The pain of PFPS often worsens with prolonged sitting or descending stairs. The most sensitive physical examination finding is pain with squatting. Examining a patient's gait, posture, and footwear can help identify contributing causes.
Can a plain radiograph of the knee be used for PFPS?
Plain radiographs of the knee are not necessary for the diagnosis of PFPS but can exclude other diagnoses, such as osteoarthritis, patellar fracture, and osteochondritis. If conservative treatment measures are unsuccessful, plain radiography is recommended.
Why does my patella flex out?
Patellofemoral pain syndrome can also be caused by abnormal tracking of the kneecap in the trochlear groove. In this condition, the patella is pushed out to one side of the groove when the knee is bent.
What is the condition called when you have pain in your knee?
In some cases of patellofemoral pain, a condition called chondromalacia patella is present. Chondromalacia patella is the softening and breakdown of the articular cartilage on the underside of the kneecap. There are no nerves in articular cartilage—so damage to the cartilage itself cannot directly cause pain.
What is the pain in the front of the knee called?
Patellofemoral Pain Syndrome. Patellofemoral pain syndrome (PFPS) is a broad term used to describe pain in the front of the knee and around the patella, or kneecap. It is sometimes called "runner's knee" or "jumper's knee" because it is common in people who participate in sports—particularly females and young adults—but PFPS can occur in ...
What is the pain in the kneecap called?
Patellofemoral pain syndrome occurs when nerves sense pain in the soft tissues and bone around the kneecap. These soft tissues include the tendons, the fat pad beneath the patella, and the synovial tissue that lines the knee joint.
Why is it called a runner's knee?
It is sometimes called "runner's knee" or "jumper's knee" because it is common in people who participate in sports—particularly females and young adults—but PFPS can occur in nonathletes, as well.
How to test for knee pain?
To determine the exact location of the pain, your doctor may gently press and pull on the front of your knees and kneecaps. He or she may also ask you to squat, jump, or lunge during the exam in order to test your knee and core body strength.
Can patellofemoral pain be recurrence?
Patellofemoral pain syndrome is usually fully relieved with simple measures or physical therapy. It may recur, however, if you do not make adjustments to your training routine or activity level. It is essential to maintain appropriate conditioning of the muscles around the knee, particularly the quadriceps and the hamstrings.
