26 One study found that athletes with patellar tendinopathy were generally younger, taller and weighed more than those without patellar tendinopathy.3 Infrapatellar fat pad size was significantly larger in those with tendinopathy than in controls.27 There are few papers providing Pfizer Licensed Compound Library price evidence on assessment procedures, therefore this section is based on expert opinion. As with all musculoskeletal conditions, a detailed history is very important

and must first identify if the tendon is the likely source of pain. This is determined initially in the history by asking the person to indicate where they feel their pain during a patellar tendon-loading task (such as jumping and changing direction). They should point with one finger to the tendon attachment to the patella; more widely distributed pain should raise the possibility of a different diagnosis. Second, a history should identify

selleck compound the reason that the tendon has become painful; this is classically due to tendon overload. Two common overload scenarios are seen: a large increase in overall load from a stable base (eg, beginning plyometric training or participation in a high-volume tournament) or returning to usual training after a significant period of downtime (eg, return to training after 4 to 6 weeks time off for an ankle sprain or holidays). Elite athletes can have repeated loading/unloading periods due to injuries and season breaks over several years, which gradually reduces the capacity of the tendon to tolerate load and leaves it vulnerable to overload with small changes in training. No identifiable change in load or pain induced from a load that should not induce

patellar tendinopathy (such as cycling) should suggest alternative diagnosis. mafosfamide Pain behaviour also has a classic presentation: the tendon may be sore to start activity, respond variably to warm-up (from completely relieving symptoms to not at all) and will then be worse the next day, which can persist for several days. The athlete will rarely complain of night pain and morning stiffness (unless symptoms are severe), but will complain of pain with prolonged sitting, especially in a car. Pain with sitting can be a good reassessment sign as the condition improves. Pain during daily activity is also common; stairs and squatting are provocative. Most athletes who present clinically with patellar tendinopathy are good power athletes; they will describe being good at jumping and being quick, especially in change of direction.28 They will complain that their tendon pain affects their performance, reducing the attributes that allow them to excel at sport.
