What remidies (that actually work) help patella femoral syndrome?

Question

I have pattella femoral bilateral syndrome and my knees have been hurting lately. I do where knee braces but I was wondering if anyone had any really good remedies (stretches, ice,heat, etc.) that actually work.

Answer 1

Stop running.
Get new running shoes. This to fix the angle your foot hits the ground and to provide cushioning.
Get orthotics. This to fix the angle your foot hits the ground. Get a knee brace or support strap. This to keep your patella in its track. Taping. This is where taping is used to get the patella back into its track. Stretch. Some doctors recommend knee drops to build up the muscles around the knee. Weights. This to strengthen the muscles around the kneecap so it tracks properly. Avoid bent knee exercises. Straight leg raises and posterior (hamstring or calf) muscle stretches are best.
Massage. Icing. Take anti-inflamitories. Try Glucosamine Sulfate. They say it helps with joint pain and arthritis. Try ginger. A tea made of fresh ginger taken 3 times a day is supposed to help reduce inflammation. Prolotherapy. This is where they inject some gunk into your knee and hope your body will react and cure the cause of the pain. Acupuncture. This is where needles are used to stimulate the body to repair itself. Physiotherapy. This is where the muscles are manipulated to bring the patella back into its track. Arthroscopic surgery. This is where they cut a hole and take a look around at what's actually going on under the skin
Shaving the patella. This is where they get in and smooth the surface of the patella with a knife. Lateral release. This is where they get in and cut ligaments to shift the way the patella sits.

Patella Femoral Syndrome

Answer 4

Did you get that diagnosis from your family doctor, or from an orthopedic specialist? In my experience, family doctors use the term patello-famoral syndrome to describe knee pain that they can't explain otherwise. If you don't know the cause of the problem, you can't really correct it. A brace may help the pain temporarily, but if you don't correct the cause of the problem, the pain is likely to return. Often times, knee pain is caused by muscle imbalances in the hip, buttocks, and thigh. A physical therapist will be able to help you find the source of the problem and correct any problems. If the brace works, great, but if not, my advice is to go see a physical therapist.

One of the most common questions spouses ask when confronting a marriage crisis is this: How can I save my marriage if my partner doesn't want to help find a solution? How do I succeed I am trying to save my marriage on my own? Learn here https://tr.im/jrfrR

It is a typical enough story: one partner leaves, the other stays. One remains 'in love', the other is uncertain. Whatever it is that has caused a couple to be apart, the one person who remains bears the prospect, fear, doubt, desire, hope of saving his or her marriage' alone.

Answer 6

Oh I'm pretty sure that was what I had. I went to physical therapy though and it got a lot better. Try any excercises that work out your leg muscles especially your quads. Ice helps with the swelling. You should try physical therapy though.

Answer 7

You should have them evaluated by a physical therapist who can identify the proper structures to be strenghtened or stretched. You could make them worse if not treated properly.

Answer 8

Creatinin is the medecine

Answer 9

Most patients who have patellofemoral syndrome can be successfully treated once contributing factors are identified during history taking and physical examination. After pain and inflammation are treated, patients are encouraged to start activities that do not provoke pain. Exercise programs should be implemented that address underlying strength and flexibility deficits. Return to play primarily relies on advancement of pain-free activity, with some allowance for patients' competitive goals. Patients remaining symptomatic after compliance with a structured rehabilitation program or those with indicators of other intra-articular pathology should be referred to an orthopedist.

Clinicians in sports medicine clinics typically see many patients who have chronic anterior knee pain and often diagnose patellofemoral syndrome (PFS). Although PFS is a common diagnosis among active patients, it is a term without a universally accepted definition. PFS is often used interchangeably with other terms, such as patellofemoral pain (or stress) syndrome, patellofemoral dysfunction, or anterior knee pain. We use PFS here to describe patients who have pain over the anterior aspect of the knee without other identifiable causative pathology (eg, meniscal injury, peripatellar tendinitis or bursitis, apophysitis). Therefore, the disorder is a diagnosis of exclusion. Since assessment and treatment of this disorder often involve consideration of multiple factors, we offer a logical framework for evaluating and treating chronic patellofemoral pain.
A Multifactorial Pathophysiology

PFS often arises from a combination of intrinsic and extrinsic factors. Although quadriceps flexibility and function, genu varus, and hypermobile patellae have been identified by prospective studies as intrinsic risk factors for PFS,1,2 such studies are limited because of the disorder's multifactorial nature. Understanding PFS requires an understanding of the function of the patellofemoral joint (figure 1). It is important to appreciate the tethering effect of tendons and ligaments adjacent to the patella, as these are major determinants of forces across the joint (figure 2). In addition, overall lower-extremity alignment and the anatomic relationship between the trochlear groove and the posterior patella also produce variable forces across the patellofemoral joint. As the posterior aspect of the patella moves through the trochlear groove with knee movement, normal patellofemoral alignment and function disperse these forces across the articular surfaces.3

In patients with PFS, however, these static and dynamic factors most often produce increased forces across lateral joint surfaces and decreased forces across the medial side. Lateral pain may result from articular surface overload or adaptive shortening of the lateral retinaculum. Medial pain may result from articular surface hypoperfusion and early degeneration, or from chronic traction on the medial retinaculum.4,5 Although cartilage damage is frequently implicated in PFS, hyaline cartilage has no nerve endings, and therefore pain is generated by other structures, including the retinaculum, subchondral bone, synovium, or local small nerve endings.6 Several theories account for how biomechanics, overuse, and acute injury contribute to patellofemoral pain (figure 3).5,7

Assessing the Affected Patient

History. Pain in PFS is typically diffuse and poorly localized over the anterior aspect of the knee. Patients will sometimes report that the pain seems to be coming from "behind the kneecap." An early clue to a diagnosis is to ask the patient to point with one finger to the spot of maximal pain. Patients with PFS are often unable to pinpoint pain and instead will rub the front of their knees and complain of diffuse, rather than focal, pain within or over the anterior knee. Bilateral pain is common.

Patients with PFS will often report feeling knee swelling or "fullness," especially over the infrapatellar area, but significant swelling must raise questions of other intra-articular pathology. Buckling or subjective instability in PFS is often noted with stair use and is usually due to pain inhibition of the quadriceps. Patients will sometimes report "locking" or "catching" with PFS, which must be differentiated from the true mechanical block that can be seen with meniscal injury or loose intra-articular bodies.

Any changes in activity resulting in increased force across the patellofemoral joint should be identified. Such changes include altered training surface or terrain (especially hills and stairs), increased training volume, or other variations in training or daily activity (especially those leading to increased or prolonged knee flexion or squatting). However, in some patients a precipitating factor cannot be identified.

Patients should be asked about prior knee injuries. Previous patellar subluxation or dislocation or a fall directly onto the patella may indicate bone or articular cartilage damage that is exacerbated by normal patellofemoral forces.

Physical exam. Patients with anterior knee pain should have a complete physical examination of the knee, with particular attention to extensor mechanism function. The primary purpose of the physical exam is to look for possible sources of pathology and to assess for correctable factors that can be addressed with rehabilitation.

Assessing stance and gait. Stance and gait observations provide an overall impression of lower-limb alignment. Quadriceps bulk and symmetry; genu valgus, varus, or recurvatum; and increased foot pronation should be noted during this evaluation. Medial deviation of the knee during a one- or two-leg partial squat indicates weakness of the abductors and external rotators of the hip. Many patients with PFS will have pain with squatting, but this is also common with meniscal injury. Although much has been written about the significance of specific measures of patellofemoral alignment, several studies have shown little correlation between these measures and patellofemoral symptoms.8

Seated exam. Vastus medialis obliquus (VMO) bulk and patellar position should be assessed. Focused palpation of knee structures may reveal discrete areas of tenderness. Some causes of pain over the anterior aspect of the knee, such as pes anserine bursitis, medial plica syndrome, or Sinding-Larsen-Johansson disease, often produce focal tenderness. Fat pad and retinacular tenderness may produce tenderness over the anterior joint line.

Palpation over the patella during knee flexion and extension will often reveal crepitus, which is of debatable significance.6 One study9 that examined knee findings in normal subjects found that 40% of females had asymptomatic, and most often bilateral, patellofemoral crepitus. When crepitus is new, painful, or markedly asymmetric, however, it may signal other pathology.

Supine exams and tests. Physicians should assess active and passive range of motion of the knee and hip. Pain with hip testing, particularly with internal rotation, suggests primary hip pathology, which must always be considered in patients with knee pain. Knee ligaments and menisci should be thoroughly examined.

Flexibility assessment is an important, but often overlooked, component of the exam in patients with PFS. Particular attention should be paid to iliotibial band, hamstring, rectus femoris, and gastrocnemius and soleus flexibility. Tightness of these structures increases stress across the patellofemoral joint and is often readily treated with appropriate rehabilitation.

Specific tests of the patellofemoral joint may be performed. The patellar glide test (figure 4)10 and patellar tilt test (figure 5) assess movement of the patella. These tests primarily assess for retinacular tightness or laxity. The medial and lateral retinaculi are frequently tender and can be gently palpated using the same maneuver as the patellar tilt test. If the retinaculi are nontender, the posterior patellar facets can then be palpated as the patella is again tilted. Physicians should be aware that this retropatellar palpation is often uncomfortable, even in normal individuals, and examination of the contralateral knee can provide a baseline for patient tolerance to this test. Sagittal tilt can be assessed by observing distal patellar movement as the patient isometrically contracts the quadriceps. If the distal pole of the patella appears to move posteriorly, the action may be irritating the infrapatellar fat pad.

Compression testing done at differing degrees of flexion assesses pain as the patella moves through the femoral groove (figure 6).6 Since compression testing can be quite painful, it needs to be performed carefully and is often the final step in the physical examination.

Footwear. Physicians should also inspect shoes used for athletic activity and daily wear. The wear patterns are not often helpful in diagnosing PFS, but the condition and choice of footwear usually are. With athletic shoes, midsole cushion and support functions generally fatigue after 300 to 400 miles (about 3 months in the 30 mile/wk runner).
Imaging Studies

PFS is a clinical, rather than a radiographic, diagnosis. Most patients who have a typical history of overuse may be initially managed without imaging. However, if any red flags stand out in the history or exam—such as a significant mechanism of injury or effusion—physicians should undertake appropriate imaging studies to screen for other pathology. Physicians should be aware that abnormal patellofemoral alignment and articular cartilage changes, as assessed by radiographs and magnetic resonance imaging, are common in asymptomatic knees and do not appear to correlate with the clinical outcome after conservative treatment for PFS.11
Effective Treatment for Active Patients

Literature reviews of treatment for PFS reveal a paucity of high-quality trials on which to base treatment decisions.12-14 The relatively high rate of spontaneous recovery, especially in young patients with unilateral symptoms,11,13 and the multifactorial nature of PFS, confound therapeutic trials. Recent data suggest that patients with PFS do not have increased forces across the patellofemoral joint, but have an abnormal concentration of these forces onto a smaller articular surface area.7 This finding suggests that treatment should focus on dispersing joint forces across a larger surface area, and it supports the common treatment principle of addressing strength, flexibility, and other biomechanical factors that affect patellar tracking.

When formulating a treatment plan, the clinician needs to combine elements that have proven successful in controlled trials with information gathered from assessment of the individual patient. A key to successful treatment is to prepare patients to assume an active role in rehabilitation and to warn them that such a protocol may take several months to work. Although many patients with PFS will begin to note slight improvement shortly after initiating treatment, many studies of PFS therapies examine results after 6 to 12 weeks of nonoperative treatment.14,15 Several of these studies note continued improvement for up to 1 year.14,15

Elements of treatment. The first step in treatment is to reduce pain and inflammation. This includes regular and frequent application of ice for 15 to 20 minutes at a time, especially after activity. Nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics often provide transient relief.

Patients should be encouraged to modulate activity by continuing pain-free activity and maintaining aerobic conditioning. Patients often get relief by decreasing training intensity and volume by about 50%. If pain persists, alternative activities should be sought. Patients who cannot tolerate continued activity and those with acute injury may require rest for up to 8 weeks, or until activities of daily living are pain free. Many runners with patellofemoral pain can tolerate freestyle swimming, bicycling (with the seat elevated to avoid excessive knee flexion), or elliptical trainers without discomfort. Stair-stepping machines and step aerobics should usually be avoided. Patients should also be counseled to avoid unnecessary force across the knee (eg, cross-leg sitting, prolonged squatting).

Home exercise programs should address strength and flexibility deficits and biomechanical factors (table 1) identified during the exam. This program can either be prescribed in the office (see the Patient Adviser, "Coping With Patellofemoral Syndrome") or with several visits to a physical therapist for instruction about a home exercise program. Whichever approach, the program should include the following:

* Restoring quadriceps strength. This action is a key component to reducing symptoms and improving long-term outcome in PFS.11 Although straight-leg raises and other open-chain exercises targeting the VMO are commonly used in PFS rehabilitation, patients may do better with closed-chain exercises such as partial squats or step-downs.16
* Strengthening external hip rotators. Athletes who have weak external hip rotators often benefit from appropriate strengthening exercises.6
* Stretching tight regions. Problem structures often include the iliotibial tract, quadriceps, hamstrings, gastrocnemius-soleus complex, and lateral retinaculum.17

TABLE 1. Common Biomechanical Factors That Can Contribute to Patellofemoral Syndrome*
StructurePathophysiologic Cascade
Foot or AnkleIncreased pronation --> Increased internal tibial rotation --> Increased knee valgus

Decreased dorsiflexion or calf tightness --> Increased internal tibial rotation --> Increased
knee valgus
KneeLateral patellar tilt or retinacular tightness --> Increased pressure on lateral aspect
of posterior patella, decreased pressure on medial posterior patella, and increased
traction on the medial retinaculum
ThighDecreased VMO function --> Increased lateral movement of patella with
quadriceps activation

Quadriceps tightness --> Increased posterior force across the patellofemoral joint

Hamstring tightness --> Increased quadriceps force needed for extension
HipIliotibial band tightness --> Increased lateral traction on patella

Hip abductor and external rotator weakness --> Increased knee valgus
*During evaluation, patients should be assessed for these factors, and treatment should address them.
Most of these contributors involve dynamic effects occurring with weight-bearing activity.
VMO = vastus medialis obliquus

If patients do not begin to improve after 2 to 4 weeks of compliance with activity titration and a home exercise program, then supervised physical therapy should be more strongly advocated.

The previous PFS treatment plans are fairly universal and will likely benefit most affected patients. Some physicians will also prescribe adjunctive therapies, such as patellar taping, braces, and orthoses. It should be emphasized that experimental data on such modalities is limited and inconsistent.12,13

Although taping and braces are not substitutes for rehabilitation, they may significantly enhance comfort for some patients and allow for more effective rehabilitation. For example, taping may enhance earlier VMO firing, and most benefit appears to occur when taping is used as part of a comprehensive rehabilitation regimen.18 Cost and design of knee braces vary widely, and evidence does not support any particular type. Thus, any empiric trial should be based on patient preference.

Although recommendations for foot orthoses are common in PFS treatment, this appears based largely on theoretic grounds of their effects on kinetic-chain alignment.17 Research-based evidence is scanty.17 Some patients with increased pronation may experience benefit from over-the-counter antipronation orthoses. Heel lifts may help some patients with leg-length discrepancies or genu recurvatum.17
Return-to-Play Criteria

The longer athletes play through pain, the longer they delay full recovery. Patients should identify upcoming events or times that are most important for peak performance. During preseason or early-season training in which peak performance is not needed for several months, patients may advance activity on a pain-free basis. A general rule of thumb when allowing athletes to return to training is to have them start at about 50% of their previous volume and intensity, and then advance by about 10% per week as tolerated. Rehabilitation should be continued as they increase their training. Some patients benefit from NSAIDs during this time.

Athletes who are close to season's end and have championship events yet to go should minimize pain-generating activity during practice and try to "save themselves" for the key event. They may play with discomfort if they are able to maintain good form and a reasonable performance level, as long as they accept the trade-off that they will likely have increased pain after the event, and are delaying their full recovery.

Some patients are fortunate enough to have a single episode of PFS, but others will experience multiple relapses. Maintenance of quadriceps strength is important for these patients, as it correlates with better long-term outcome.11 Patients should be encouraged to continue or resume their rehabilitation program when anticipating activity that may aggravate their knee and to restart a short course of ice, NSAIDs, and bracing (if previously successful) at the earliest sign of symptoms. Patients should return to clinic if their symptoms increase significantly in spite of these measures, and for any new swelling, true mechanical symptoms, or acute injury. When patients return, it is important to address compliance with the treatment plan, assess and encourage incremental improvement, and emphasize that rehabilitation efforts may take 4 to 6 months before the full benefits are realized.
The Surgical Option

Surgery for PFS is indicated in those few patients who have persistent symptoms in spite of appropriate rehabilitation and who have a genuinely surgically correctible problem such as patellofemoral malalignment or articular cartilage injury. Surgery for PFS encompasses various specific procedures. One of the more common technique is a lateral release, which involves a division of the lateral patellar retinaculum. The procedure is usually performed in patients who have an excessive lateral tilt of the patella. Outcomes are highly variable. Studies reveal that between 17% and 92% of patients report satisfactory results after lateral release.19 Articular cartilage debridement is also common, and the procedure may be performed in conjunction with a lateral release or other techniques aimed at correcting malalignment.

While the literature contains widely varying rates of success for many PFS surgeries, patient selection and postoperative rehabilitation appear critical for improving chances of a favorable outcome.20 Patients whose conservative therapy has failed because of noncompliance with rehabilitation are often not good surgical candidates.
Tailored Therapy for Good Outcomes

Although treatment for PFS is sometimes frustrating for both the patient and clinician, the eventual outcomes are usually rewarding. Most of these patients will get better with appropriate and active rehabilitation, but it may take a number of weeks of effort before significant improvement is appreciated. The physician's role is often to reassess, reassure, and motivate patients as they progress through treatment. Some patients can be adequately treated with an office-prescribed home exercise program, while others may benefit from referral to a physical therapist. Patients considering surgery after lack of improvement with conservative therapy measures should be referred to an orthopedist for evaluation and treatment.
