Patellar tendinopathy is best described as what?

• A. A meniscal tear from twisting
• B. An overuse injury of the patellar tendon from jumping or stair climbing
• C. Osteoarthritis of the patellofemoral joint
• D. A cruciate ligament rupture

Answer: (B)

Patellar tendinopathy is an overuse injury of the patellar tendon caused by repetitive loading, commonly from jumping or frequent stair climbing. It reflects degenerative changes in the tendon from micotrauma and chronic overload, rather than a sudden tear. The pain is typically anterior and focal at the inferior patellar pole, and it worsens with activities that bend the knee and load the tendon, such as jumps, squats, and stair climbing, as well as with resisted knee extension. This pattern helps distinguish it from other knee problems: a meniscal tear usually presents with joint-line pain and possible mechanical symptoms like locking, an osteoarthritis of the patellofemoral joint tends to show broader anterior knee pain with stiffness and crepitus in older or worn joints, and a cruciate ligament rupture presents with an acute event, swelling, and signs of instability. Therefore, the description that best fits patellar tendinopathy is an overuse injury of the patellar tendon from jumping or stair climbing.
