Doctors concluded that this was the cause of the pain and ac- cordingly named the condition »chondromalacia of the patella« cheap 5mg compazine visa. It subsequently emerged, however, that such irregularities also frequently occur in patients without any form of retropatellar pain (who were arthroscopied for completely different reasons) and that these cannot therefore explain the symptoms. Based on the epide- miological findings, the following tentative conclusions can be drawn in respect of the etiology: The pain occurs during the pubertal growth spurt, is particularly severe when retropatellar pressure is high (walking downhill), and particularly affects tall (asthenic) girls with pro- portionately weak muscles. An imbalance must exist, therefore, between the rapidly rising retropatellar pres- sure situation resulting from the growing lever arms on the one hand and muscle (and ligament) control on the other. We can now say for sure that a »disorder« of the retropatellar cartilage is not present in most patients and that the term »chondromalacia« should not therefore be used (apart from a few arthroscopically confirmed, usu- Charlie had no anterior knee pain because he turned outwards to make his knees point straight ahead; the problem occurs primarily ally posttraumatic, cases). Investigations with computed tomography have shown that patients with anterior knee pain have significantly higher degrees of femoral antever- sion compared to a control group [4, 6]. No other differ- are more frequently affected than boys, they tend to be ences between the two groups were observed in respect of keen on sports but are typically of an asthenic rather knee parameters (shape of the condyles and the patella). The pain is at its strongest after physical anteversion and osteoarthritis of the knee. It is particularly pronounced when walking the 1970’s, we still believed that increased anteversion downhill and, to a slightly lesser extent, when walking was a problem for the hip, it now appears to be more of uphill. Although the connections with knee with tenderness over the patellar facets, usually on tibial torsion have not been studied sufficiently to date, the medial rather than the lateral side. One specific test since the knee position during walking correlates more is for the »Zohlen sign«: With one hand the examiner closely with the rotation of the lower leg and feet than grasps the top of the patella and presses it against the the rotation of the thigh, such a connection probably femoral condyles. Rotation anomalies probably have a greater influ- in every case if sufficient pressure is applied, its value in ence on the loading of the knee than axial devia- differential diagnosis is doubtful. Crepitation is a non- tions – a problem that has been almost completely specific sign and is not an indication of retropatellar ignored to date. In an investigation involv- ing 123 young adults, crepitation was noted in 60% of cases, whereas retropatellar pain was present in only 3% Clinical features. Contracture of the quadriceps muscle (restricted Anterior knee pain is common in adolescence and is knee flexion with hips extended) is also occasionally typically characterized by the following factors: Girls observed.

The term anserine (“goose’s foot”) purchase compazine 5 mg without a prescription, relates to the peculiar anatomic configuration of the insertion of the tendons of the sartorius, gracilis, and the semitendonosis as they gain entry onto the upper medial portion of the tibia. The tendons with their investing synovial sheath lie adjacent to the bursa. The source of pain in this region is a mechanical tendinitis arising from repetitive rotary movements of the tibia on the femur, particularly along the medial aspect of the knee. The condition is commonly seen in people involved in “twisting” motions at the knee, such as football players, runners, gymnasts, and ballet dancers. It is usually unilateral, although there are occasional cases of bilaterality. Bilateral cases should prompt Adolescence and puberty 104 investigations into inflammatory arthropathies, particularly juvenile rheumatoid arthritis. It is also seen in association with osteochondromas of the upper proximal medial tibia, but the vast majority of cases are of the pure mechanical type. Most typically the pain is seen with mechanical activities, particularly running and twisting of the knee. Pressure applied directly over the tendons themselves at their site of insertion will reproduce the pain (Figure 5. In the absence of an underlying osteochondroma, the treatment is generally conservative, and will nearly always result in resolution of symptoms. Ice, heat, in concert with nonsteroidal anti-inflammatory medication combined with occasional periods of activity restriction or physiotherapy, will generally result in pain relief within six weeks to three months. Surgery must be considered meddlesome, except in cases of underlying bony pathology. Fabella syndrome In roughly 12 percent of humans, a sesamoid bone is found imbedded in the tendinous portion of the lateral head of the gastrocnemius muscle, directly adjacent and posterior to the lateral femoral condyle and commonly articulating with the condyle itself (Figures 5.

Although psychological treat- ments appear to be effective discount compazine 5mg otc, not all patients benefit equally. A number of studies have identified subgroups of patients based on psychosocial and behavioral characteristics (e. Dahlstrom and colleagues (Dahlstrom, Widmark, & Carls- son, 1997) found that when patients were classified into different subgroups based on their psychosocial and behavioral responses during assessment, they responded differentially to treatments. Similarly, Turk, Okifuji, Sinclair, and Starz (1998b) noted differential responses to a common treatment for patients with distinctive psychological characteristics but identical physi- cal diagnoses. Chronic pain syndromes are made up of heterogeneous groups of peo- ple, even if they have the same medical diagnosis (Turk, 1990). Patients with diseases and syndromes as diverse as metastatic cancer, back pain, and headaches show similar adaptation patterns, whereas patients with the same diagnosis can show marked variability in their degrees of disability (Turk et al. Research studies looking only at group effects may mask important issues related to the characteristics of patients who successfully respond to a treatment. Only a handful of studies have actually begun to demonstrate that matching treatments to patient characteristics, derived from assessments, is of any benefit (e. More studies targeted toward matching in- terventions to specific patient characteristics are needed (Turk, 1990). De- veloping treatments that are matched to patients’ characteristics should lead not only to improved outcomes but also to greater cost-effectiveness. In order to advance the area of pain assessment, additional studies of how these assessments can inform and improve treatments are desirable. Moreover, as we learn more about patient–treatment matching, pain as- sessment procedures should reflect this progress. CONCLUSION Symptoms of chronic pain are extremely distressing and many times there is no cure or treatment capable of substantially reducing all symptoms. At the present time, rehabilitation, including improvement in emotional func- tioning, physical functioning, and quality of life, is the goal.
