Links The structures most commonly affected are the undersurface of the kneecap (or patella) and the end of the femur or thigh bone which forms a groove in which the patella slides. There may also be some inflammation of the patella tendon which is the attachment point of the quadricep muscles and the kneecap is incorporated in this tendon. These problems can exist individually or may present together. Predisposing factors for this condition include tight muscles (quadriceps , hamstrings and iliotibial band), internal rotated femur and tibia which is often secondary to excessive pronation of the foot and poor postural stability at the level of the hips and pelvis. Training changes such as increased workload, intensity or slope can also have an effect on the knee. Quadricep muscle weakness also upsets the balance of forces around the knee joint. Clinically the patient often presents with a vague ache, often aggravated by activity and may have some degree of swelling, creaking/grinding behind the kneecap. Some people will have pain after periods of rest especially sitting. It is important to have the injury correctly diagnosed to rule out more serious structural damage and to accurately determine which factors are contributing to the ongoing problem.
Patellofemoral Pain Syndrome Homepage Patellofemoral pain syndrome is known by other names such as Patellar Chondromalacia, Excessive Lateral Pressure syndrome and simply anterior knee pain. http://www.emedx.com/emedx/diagnosis_information/knee_disorders/patellofemoral_p
Extractions: The pain associated with this disorder may worsen with descending stairs climbing or deep squating. Sitting with your knees flexed for a long period of time in a car or movie theatre may also aggravate the symptoms. Causes A variety of underlying anatomic abnormalities may result in patellofemoral pain syndrome. It can be caused by softening or cracking of the articular cartilage under the kneecap. This is known as chondromalacia. A malalignment of the kneecap or tight tissue around the kneecap can also create tension that may lead to patellofemoral pain syndrome.

Extractions: It's an inescapable fact that knee injuries are a part of sports. One of the most complex joints in the body, the knee must withstand and absorb an incredible assortment of forces, both natural and unnatural, in order for an athlete to jump, run or cut. One of the structures of the knee, the patella (or kneecap) is particularly prone to pain and discomfort primarily because it sits at the juncture of ligaments, tendons, cartilage and bone. These afflictions, collectively referred to as patellofemoral pain syndrome, may have many causes. Dr. Giles Scuderi, a member of the Association of Professional Team Physicians (PTP) and an attending orthopedic surgeon at Beth Israel Medical Center, joins us to discuss this syndrome the causes, treatments and prognosis. What is patellofemoral pain syndrome?
Patellar Tracking Disorder -- Topic Overview This kind of pain, called anterior knee pain or patellofemoral pain syndrome, is sometimes caused by a common kneecap problem known as patellar tracking http://my.webmd.com/hw/raising_a_family/tn7305.asp
Extractions: Topic Overview Patellar tracking disorder is a condition in which the kneecap (patella) shifts out of place as the leg bends or straightens. Your knee joint is a complex hinge joining the lower leg bones (tibia and fibula) with the upper thighbone (femur). The kneecap (patella) is anchored to the front of the knee joint by tendons on the top and bottom and by ligaments on the sides. A layer of cartilage lines the underside of the kneecap, helping it glide along the groove at the end of your thighbone. The kneecap can shift or rotate off track if the groove is too shallow or if the cartilage is damaged. Ligaments, tendons, or muscles that are too loose or too tight may also lead to a malaligned kneecap. See an illustration of the knee joint What causes patellar tracking disorder?

Extractions: Home Reference Treatment Techniques McConnell Treatment for Anterior Knee Pain Patellofemoral pain, also referred to as anterior knee pain, is a common musculoskeletal condition in the general and sporting communities. It affects up to 25% of the population, 36% of adolescents and is more prevalent in females. Patellofemoral Pain Syndrome is characterised by anterior or peri-patellar knee pain in the absence of other knee pathology. This pain can be diffuse or sharp and is usually associated with at least two of the following activities: It may be associated with crepitus on knee movements, occasional swelling particularly after exercise, and pseudo locking or giving way. Role of physiotherapy Physiotherapy is the mainstay of conservative treatment for this condition and the Australian physiotherapy profession has received international recognition for anterior knee pain management. The most effective treatment for patellofemoral pain is a McConnell program, designed and monitored by a physiotherapist according to the patient's individual needs. This recognised anterior knee pain management program was first introduced by Jenny McConnell, an Australian physiotherapist (McConnell, 1986). The approach uses a specialised, functional exercise program to improve the muscle control around the knee and taping to reposition the patella.

Extractions: Study Finds "Clear, Durable Effect" in Reducing Pain and Improving Function By Michael Devitt, Managing Editor According to the National Institutes of Health, more than four million people seek medical care for a knee problem each year. A leading cause of chronic knee pain, particularly in young adults, is patellofemoral pain syndrome (PFPS). The condition occurs most frequently in adolescents who participate in sports, and is one of the most common diagnoses given at orthopedic centers and sports medicine clinics worldwide. Despite its prevalence, the contributing factors to patellofemoral pain syndrome are unclear. Although several studies have linked knee pain to certain physical activities, there seems to be no direct correlation between the level of pain and the degree of cartilage damage to one's knee, or to the amount of flexion or extension a person's knee experiences. To date, no single therapy has been shown to be completely effective in treating PFPS. However, acupuncture has shown promise in treating similar conditions such as gonarthrosis and osteoarthritis of the knee.

Extractions: Scott A. Paluska, MD; Douglas B. McKeag, MD, MS Department Editor: William O. Roberts, MD THE PHYSICIAN AND SPORTSMEDICINE - VOL 27 - NO. 8 - AUGUST 1999 D isorders of the patellofemoral joint are common in recreational and competitive athletes. The pathophysiology of these disorders is unclear but may be related to malalignment of the patella and femoral trochlea, which may produce the characteristic anterior knee symptoms (1). Diagnosing and treating patellofemoral pain syndrome is challenging but important, since patellofemoral abnormalities can result in substantial discomfort and disability. One treatment measure that many patients find helpful for anterior knee pain is the simple-to-fit, inexpensive patellofemoral knee brace (PFB). These braces are best used as an adjunct to other therapies. PFBs were designed to minimize lateral patellar subluxation and dislocation, improve patellofemoral tracking, and decrease anterior knee pain (2). They are also intended to provide proprioceptive feedback and warm the patellofemoral joint. PFB manufacturers have made many claims about the efficacy and benefits of their braces, but most assertions have not been supported by scientific investigation or analysis (3). As with other types of knee braces, however, patients who have worn PFBs report benefits that exceed the objective effects noted by researchers (3,4). While PFBs do not appear to alter underlying biomechanical dysfunction, they provide a static restraint that (in most cases) applies a medially directed force to the lateral patella, thereby decreasing abnormal patellofemoral tracking. The sleeve itself helps compress the tissues and limit excessive patellar movement.

Extractions: CPT Chad Asplund, MD; COL Patrick St Pierre, MD THE PHYSICIAN AND SPORTSMEDICINE - VOL 32 - NO. 4 - APRIL 2004 For CME accreditation information, instructions and learning objectives, click here In Brief: Anterior knee pain and patellofemoral pain syndrome are among the most common leg overuse injuries in cyclists. Bicycle fit, recent change in equipment, training distance and intensity, and individual anatomic factors are important evaluation considerations. Clinicians need a basic understanding of bicycle fitting and how anatomic factors and training errors contribute to repetitive stress injuries. After problems are addressed, a gradual return to activity is recommended to avoid further injury and improve performance. W ith Lance Armstrong's successes in the Tour de France and the increasing popularity of mountain biking, participation in bicycling has steadily increased over the past 10 years. Cycling is an excellent alternative for runners and other athletes seeking low-impact exercise. The Bureau of Transportation Statistics at the US Department of Transportation estimates that more than 49 million Americans ride bicycles at least monthly, with over 5 million people riding at least 20 days per month. The number of cycling-related injuries has also risen, with the majority caused by overuse. Injuries may also be related to improper bicycle fit or equipment, poor technique, or inappropriate training patterns. Cycling is very repetitive; during 1 hour of cycling, a rider may average up to 5,000 pedal revolutions. The smallest amount of malalignment, whether anatomic or equipment related, can lead to dysfunction, impaired performance, and pain.
Extractions: When bumped with force, the knee-cap can sometimes be moved from its place at the front of the knee to either side but most commonly to the outside. A dislocation has been sustained when it 'pops' out of its groove and stays there. If the patella only slides out part of the way this is known as a subluxation. Patella tendonitis usually is caused from excessive stress to the patella tendon. Jumpers knee is a term commonly used. It is not a sudden injury but a wear and tear soreness the you may notice over time during and after activity. Pain will be felt as a burning and will be worst following exercise. Quadriceps tightness and weakness may accompany patella tendon pain Kicking a ball regularly or constantly squatting or climbing stairs might trigger the soreness.
Extractions: e-mail David P Johnson Optimum knee function is of vital importance in a wide variety of sports. Knee stability is important in runniing, twisting, jumping and pivoting. Injuries to the knee are very common because of the lack of bony congruity and its reliance on muscular and ligamentous support. Knee injuries are the most common serious injury during sporting activities. Anterior knee pain affects 29% of adolescent children (Fairbank 1984). This may be related to the increase in structured sporting activity which occurs at school during early adolescence. Anterior knee pain is particularly prevalent in certain sports which include basketball, netball, athletics, skiing and cyclling. In these sports activities are undertaken whilst the knee is in a flexed position, and or jumping is common. To understand the patho-mechanics of anterior knee pain, the anatony, clinical examination and mechanics of the knee must be well understood. Much of the confusion surrounding anterior knee pain has been produced by the inability of the practitioner to translate distinct clinical problems into a specific classification. This applies whether they be a general practitioner or hospital consultant (Ref).

Extractions: Anterior Knee Pain (AKP) is a nonspecific diagnosis that refers to pain expressed in the anterior region of the knee. It is a common clinical problem seen in all age groups and presented to general practice, sport medicine, orthopaedic and emergency department settings. Previous studies by our research group have confirmed that a paucity of consensus exists in the following areas definition classification , assessment, diagnosis and management of anterior knee pain. This lack of consensus and the ambiguity of the term 'anterior knee pain' creates confusion and frustration for both the clinician and the patient. Anterior Knee Pain has been referred to as any one of ' patellofemoral pain syndrome chondromalacia patellae recalcitrant anterior knee pain patellofemoral stress syndrome femoropatellar pain syndrome patellofemoral arthralgia ' or ' patellalgia '. Without consensus on the definition, etiology and/or management of anterior knee pain, a symptom such as pain in the anterior region of the knee becomes accepted as a diagnosis. The treatment process then results in a subjective focus on the symptoms rather than individualizing treatment based upon causative and/or etiologic factors. The use of consensus statements in the assessment and management of knee disorders may assist in alleviating the confusion for patients and physicians, and may result in more efficient use of health care dollars. The AKP research group is undergoing a multi-phased approach to developing consensus statements in the areas of definition, assessment, diagnosis and management. Consensus that is based upon current scientific literature coupled with 'expert' opinion and review assists in providing a strong foundation for developing clinical guidelines.
