Osgood-Schlatter Disease (Youth Knee Pain)
(Knee pain below knee joint)
* condition that causes pain and swelling below the knee joint, where the patellar tendon attaches to the top of the shinbone (tibia), a spot called the tibial tuberosity.
*Common cause of knee pain in CHILDREN/GROWING ADOLESCENTS.
*It is a traction apophysitis at the skeletally immature tibial tubercle due to repetitive strain on the secondary ossification center of the tibial tuberosity.
*It can lead to inflammation of the patellar tendon at the tibial tuberosity, resulting in pain and swelling just below the knee.
*Traction apophysitis occurs when repeated excessive load pulls on the tendon insertion causing partial avulsions of the apophysis and inflammation
Develops between 9-15 Y/O
The tibial tubercle consists of cartilaginous tissue in girls < 11 y/o and in
boys <13 y/o.
The unossified tibial tuberosity is more susceptible to injury.
Common in YOUNG ADOLOSCENTS who PLAY SPORTS
- Repetitive strong Quadriceps contraction
- Patellar tendon excessively strained
Repeated traction apophysitis on the anterior portion of the developing can cause the ossification center to crack
- This can result in callus formation during healing.
- The affected area may become fibrous, creating a separate persistent ossicle, or may show complete bony union with some enlargement of the tibial tuberosity.
- Avulsion fracture of tibial tuberosity may also occur
- Age: female (11-13 years old) & male (12-15 years)
- OSD was originally reported to occur more in male compared to female. However, recent studies have shown that there is no significant difference in the prevalence of OSD between males & females.
- The incidence is higher in athletes than non-athletes (21& to 4.5%)
- Rapid skeletal growth
- Training program
- Lower extremity flexibility
- reduced core stability
- Complains of pain in the tibial tubercle or patellar region after physical activities
- Palpable & painful lump below the knee
- Pain worsens with physical activities
- Tightness of the Quadriceps
- The diagnosis is based on typical clinical findings (see clinical presentation).
- Radiographic examinations of both knees to rule out the possibility of tumors, fractures, ruptures or infections.
- Sonographic examination can also be used: cartilage and bony surface, the patellar tendon, soft-tissue swelling anterior to the tibial tuberosity, and fragmentation of the tibial tuberosity.
- Stretching exercise
- Strengthening exercise
- Patient education
