Chondral fissur: You describe a sudden painful pop or catching that can be a one time event or if it recurs, especially at same knee bending angle repeatedly and reproducibly then it is more likely a patellar cartilage lesion or fissure. A thorough orthopaedic evaluation with appropriate imaging will reveal diagnosis.
