Osgood Schlatter Lesion

- Discussion:
    - refers to partial avulsion of the tibial tuberosity (anterior surface of apophysis) which has no involvement of tibial physis;
    - usually occurs in late childhood or early adolescence;
    - more common in boys;
    - may represent an over use disease;
    - repetitive stress on tuberosity may cause partial avulsion;
    - a painful non union will develop, if intervening gap fills with fibrous tissue rather than bone;

- Anatomy:
    - in fetus, tibial tuberosity develops from anterior aspect of proximal epiphysis;
    - it subsequently develops its own growth plate and during childhood, it develops its own center of ossification;
    - this ossification center expands proximally and by age 17, it blends with ossification center of the tibial epiphysis;

- Clinical Manifestions:
    - local swelling and tenderness;
    - pain is aggravated by direct prssure of tibial prominence & jumping;

- Diff Dx:
    - avulsion of tibial tubercle:
           - Osgood-Schlatter disease may be a risk factor for complete avulsion of the tibial tubercle;

- Radiographic Findings;
    - radiographs will not be helpful if injury occurs during preossification phase;
    - once the ossification center develops, radiographs will reveal radiodense fragments separated from tibial tuberosity;

- Non Operative Treatment:
    - avoidance of strenuous exercise and jumping sports;
    - some pts may require bracing or a sleeve cast;
    - expect complete resolution w/ in 1-2 yrs in most patients;

- Surgical Treatment: rarely necessary
