Definition of Kneecap
Kneecap: The patella, the small bone in the front of the knee. The patella is a little (sesamoid) bone, embedded in the tendon of insertion of the quadriceps muscle. If the patella is shattered beyond repair, it can be removed in an operation called a patellectomy and sometimes replaced with prosthetic material.Source: MedTerms™ Medical Dictionary
