Commonly a “figure four” sign is seen buy generic glucotrol xl 10 mg, or a “Q” sign buy 10 mg glucotrol xl, which relates to the movement of the patella within the intercondylar groove as the knee is brought into full extension (Figure 5. In full extension it is usually 95 Pain syndromes of adolescence possible to displace the patella laterally with very little pressure (light thumb pressure). Provocative pressure on the patella in an attempt to sublux the patella laterally will often elicit “guarding” or apprehension on the patient’s behalf. Not uncommonly, there will be tenderness over the medial capsule and retinaculum on direct pressure. Although radiographs may be occasionally helpful in discerning the relative degree of formation of the lateral condyle and the position of the patella within the groove, the diagnosis is established on a clinical basis. Long-term disability encountered with this condition relates to the degree of subluxation and dislocations and the length of time the dislocations have been occurring. Chronic dislocations will likely result in wear and tear changes on the undersurface of the patella as well as on the lateral femoral condyle, and can indeed precipitate premature patellofemoral arthritis. An awareness of the diagnostic features will facilitate appropriate orthopedic referral by the primary care physician. Although treatment is often conservative, with exercises to maintain quadriceps strength, and occasional bracing to inhibit lateral subluxation, a number of youngsters will fail conservative care and will require surgical realignment. A variety of surgical realignment approaches are available, with satisfactory results to be anticipated in the majority of cases if performed prior to the development of patellofemoral arthritis. Pain syndromes of adolescence Patellofemoral pain syndrome Traditionally patellofemoral pain syndrome had been termed chondromalacia patella and probably accounts for the greatest number of all cases of knee pain seen in adolescents. The Adolescence and puberty 96 reason for the terminology change relates to the fact that most cases of the patellofemoral pain syndrome do not show pathologic evidence of true chondromalacia of the patella, by either gross anatomic or histologic changes. Characteristically, it is seen more commonly in females although it is often seen in males.
