Extractions: The following paper aims at outlining the most common causes of anterior knee pain of which are commonly grouped into the category of Patellofemoral Pain Syndrome. Due to the enormity of the topic at hand acute injury related to trauma will be omitted. The purpose of the literature review is to briefly outline current concepts in the understanding of conditions, and the discussion will highlight details with respect to differential diagnosis. It is assumed that the reader has previous knowledge of knee biomechanics, as these will be briefly intimated in the formulation of etiological factors. A major limitation of this paper is the lack of inclusion of treatment strategy, largely due to the brevity of the paper in relation to size of the topic. Back to index.

Extractions: ICB Medical Distributors Company Profile Products Fitting Instructions ... Wanted Knee Pain (Patello Femoral Syndrome or Chondromalacia Syndrome) Can be a general term for general knee pain. If the knee cap is displaced and is not tracking correctly over the femur, inflammation and pain can occur to the underside of the patella. Knee pain can be a common problem among people active in sports which involve running and general flexing of the knee joint. One of the most common causes of knee pain is chondromalacia or patello femoral syndrome generally caused by an irritation of the undersurface of the kneecap (or patella). The irritation can lead to a roughening of the kneecap which normally should be smooth on the undersurface, a condition called chondromalacia. The patient experiences acute pain at certain points of the biomechanical gait, generally resulting from pressure of the kneecap as it becomes irritated and roughened. The tracking of the patella is particularly important as it moves in a groove at the lower end of the femur (thigh bone). The patient may complain about pain either side or under the patella and often of a dull ache after exercise, including sporting activities, or upon rising from a prone or seated positions. The amount of internal tibial "rotation" is directly proportional to the amount of excess pronation and so medial displacement of the patello femoral path laterally displaces the patella moving the patella from its correct tracking position and thereby encouraging wear and tear on the cartilage with resultant pain and inflammation.

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.

Extractions: Eugene Sherry 10 / Injuries of the Knee Eugene Sherry Mechanism of injury The knee is the most commonly injured part of the body in sport. Meniscal tears These usually occur when the flexed knee is externally rotated. The meniscus, usually the less mobile medial, is caught between the bone ends and torn (Fig. 97). Footballers and downhill snow skiers when changing direction are prone to this (Fig. 98). Clinical features Treatment This includes rest, ice, compression and elevation. Arthroscopic partial medial meniscectomy is indicated for a large tear which remains symptomatic. The meniscus is repaired when the tear is at the menisco-capular junction, especially in children (Fig. 99). Mechanism of injury Tears of the anterior cruciate ligament The cruciate ligaments stabilise the knee. The anterior cruciate (ACL) may rupture when a valgus/external rotating force is applied to the knee as when cutting in football or in the hyperflexed or hyperextended knee.

Extractions: Orthopaedic Updates Lahey Homepage Appointment Request Physician Finder Site Map / Search Back The term chondromalacia patella refers specifically to a pathological condition resulting in structural changes in the cartilage surface of the kneecap. These changes may be as mild as softening and discoloration of the normally firm, white glistening surface. if the process continues, fissuring and fraying may occur with the more advanced stages resulting in full thickness cartilage loss with exposure of the underlying bone. The process may be localized to one small area or it may involve the entire surface of the patella. Because of these variations in the cartilage changes, the symptoms experienced by patients with chondromalacia may vary. The patella aids the quadriceps muscle in extending the knee by improving it's mechanical advantage. The articular surface of the patella is the thickest in the body (four to six millimeters). Walking on level ground exerts a patellofemoral force equivalent to one-half the body weight, climbing stairs between 3-8 times the body weight, and rising from a full squat can generate forces eight times the body weight. Although chondromalacia may develop following an acute injury to the knee (direct blow, fracture, or dislocation of the patella), more commonly, it has an insidious onset not specifically related to any one traumatic event. Any anatomical variation which results in "mal tracking" of the patella in the femoral groove during knee motion, may expose the cartilage to larger loads than it can withstand resulting in abnormal wear. Predisposing factors include anatomical variations in patellofemoral groove, tight supporting structures, rotational malalignment of lower extremity (traumatic or developmental), or altered test alignments.
Infrapatellar Fat Pad Syndrome Infrapatellar Fat Pad syndrome. Although the fat pad has been implicated as a commoncause of anterior knee pain, there is insufficient evidence for this to be http://members.optushome.com.au/physio/infrapat.html
Extractions: Although the fat pad has been implicated as a common cause of anterior knee pain, there is insufficient evidence for this to be a definite fact. Additionally, as there are no clear clinical features, the condition is unable to be diagnosed and treated with any certainty. A horizontal cleft is located in the posterior aspect of the infrapatellar fat pad. It is a common and normal MR imaging finding with a prevalence of 90%. The horizontal cleft is lined with synovium and its roof is formed by the ligamentum mucosum (infrapatellar plica). This cleft communicates with the knee joint. A distended cleft can form a prominent recess mimicking pathologic processes; conversely, disorders can arise in the cleft. There is an ill-defined syndrome that involves pain and swelling of the infra-patella fat pad, sometimes referred to as Hoffas disease. At times the fat pad may be entrapped between the tibia and femoral joint surfaces resulting in a block to extension of the knee, verified at arthroscopy. The condition is considered to be related to impingement and inflammation of the infrapatellar fat pad. It is considered that the infra-patellar fat pad can become symptomatic following a direct blow, or by impingement between the femoral condyles and the tibial plateaus in extension. It can be severely inflamed by hyperextension trauma or direct rubbing by the inferior pole of the patella. Thus, the fat pad may be the cause of acute pain. It has been proposed that fat pad pain is nearly always secondary to other knee joint pathology.
Extractions: Musculoskeletal problems are some of the most frequent seen health problems in acupuncture clinics. Pain seems to be the main complaint in addition to reduced function. According to Traditional Chinese Medicine (TCM) obstruction of qi and/or blood lead to pain. Soreness, swelling, and stiffness in muscles and joints develop if the obstruction is not cleared, and the normal function of the whole body can be affected. As a result, daily life, recreational activities and participation in sports suffer. Reduced ability to work may put a strain on private and community economy. Reduced function due to obstruction of qi or blood in the knees may affect all ages, both sexes, athletes and those with sedentary lifestyles. The patients experience pain in the knee on activity and/or at rest. It is claimed to affect as many as one in four of us, and as many as 15% of young men attending military service 1, 2. Adolescents participating in sports seem to be particularly vulnerable to knee problems3, and anterior knee pain is one of the main diagnoses at sports medicine centres4. In western medicine various terminology has been applied to this problem, such as chondromalacia patellae, anterior knee pain, or knee arthralgia. The current terminology is "Patellofemoral Pain Syndrome"5. Symptoms include chronic knee pain of insidious onset aggravated by walking uphill or downhill, squatting, kneeling, or prolonged sitting with flexed knees5. Excluded are those cases of anterior knee pain that occur secondary to trauma and/ or dislocation of the patella.
Extractions: Phase I Clinical Goals: Testing: Exercises: A.Control of pain and inflammation Application of ice bags or ice cups three to four times per day for ten to twenty minutes. Modalities such as high volt electrical stimulation and ultrasound/ice massage contrast may be of benefit in this phase of rehabilitation on a limited basis For patients with patellar tendonitis : deep transverse friction massage should be performed over the tender aspect of the patellar tendon for ten minutes one time per day. The patient should glide the patella distally toward the foot. The massage should be directed perpendicular to the patellar tendon using the thumb. The massage will serve to reduce the unorganized alignment of collagen fibers and break up scar tissue during the healing process. This will allow equal stress across the patellar tendon during muscle contraction and will help achieve normal length and strength of the patellar tendon. Non-steroidal anti-inflammatory medications as prescribed by their physician.

Knee Syndromes And Arthroscopic Knee Procedures 3 Lateral pain syndrome. anterior knee pain. Many people, of all ages and sportingactivity, have pain generally located to the front (anterior) of the knee. http://www.kneeclinic.com.au/papers/ArthProcedures.htm
Extractions: Orthopaedic Knee Surgeon There are many knee operations that can be performed using an arthroscope. Most operations can be done as a day-case procedure although many patients require a period of muscle strengthening afterwards to obtain the best outcome. Below is an outline of the commonest "knee syndromes" and the arthroscopic procedures used to treat them. 1: Locked Knee A torn meniscus can displace into the knee joint causing a mechanical block to extension and resulting in pain and muscle spasm. The classic type of meniscal tear producing a locked knee is the "Bucket Handle" tear. The torn meniscus remains attached front and back allowing the central torn portion to flip into the knee joint like the handle of a bucket. As the pain and spasm reduce the displaced meniscus can drop back allowing the knee to move freely again. This mechanical "locking" of the knee can be an intermittent feature with symptomless periods of in-between episodes. The gradual onset of pain aggravated by twisting, squatting and catching your toe; as well as pain at night when you sleep on the side with legs together. This is typical of a cleavage tear of the medial (inner) meniscus which can intermittently be "pinched" by the knee joint as it flexes or twists suddenly. In-between episodes the torn portion of meniscus can fold away under the untorn meniscus and the knee become pain free.
