It is a prevalent cause of knee pain in pediatric populations. The condition manifests as pain and heightened sensitivity at the attachment point of the patellar tendon, which connects the lower portion of the kneecap to the tibia (shinbone). It is more commonly observed in boys, occurring three times more frequently than in girls. Boys typically experience this condition between the ages of 11 and 15, whereas girls are more commonly affected between 8 and 13 years of age. It can affect one or both knees. During the growth phase, the abrupt contraction of the quadriceps muscles in the thigh results in the separation of the periosteum (the membranes encompassing the bone) from the tibial tuberosity (a bony prominence at the front of the shinbone) at the loose bone-tendon attachment site.
The pain intensifies with movement and diminishes with rest. The patellar tendon may exhibit thickening. The affected area is tender to touch. Pain is also experienced during full flexion and extension of the knee joint.
Treatment:
The condition typically resolves spontaneously within a period of three months with restricted movement. Engagement in sports activities is prohibited during this period. Hot and cold therapies can be employed. If conservative measures prove ineffective, corticosteroid injections may be administered. Surgical intervention carries significant risks and may result in complications such as an elevated kneecap, posterior knee extension, and cartilage damage. Spontaneous recovery generally occurs around the age of 15.
