📌 Patella Alta
- Patella Alta refers to an abnormally high position of the patella.
- Clinical Associations:
- Reference: Stoller's Orthopaedics and Sports Medicine, David W. Stoller, 2016
✅ Example:
- Patellar Sleeve Fracture: Unique to the pediatric population (8-12 years). These fractures involve the avulsion of the inferior pole of the patella, termed a “sleeve fracture” because a sleeve of unossified cartilage and bone is stripped off the lower pole of the patella.
📌 Patella Baja
- Definition: Patella Baja is characterized by an abnormally low position of the patella.
✅ Clinical Associations:
- Often seen with Osgood-Schlatter disease
- May result from patellar realignment procedures involving repositioning or shortening of the patellar tendon
- Can occur post-surgery (e.g., tibial tubercle transfers, total knee arthroplasty)
- Reference: Stoller's Orthopaedics and Sports Medicine, David W. Stoller, 2016
✅ Additional Notes:
- Patella baja is usually not associated with functional abnormalities.
- Adults with prior Osgood-Schlatter disease findings are more likely to have patella alta, which can lead to patellofemoral maltracking, chondrosis, and transient patellar dislocation.
