Summary
A rare bilateral distal patellar tendon avulsion occurred in a young soccer player after a jump. Surgical repair yielded excellent results, suggesting a new subtype of this knee injury.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Pediatric Traumatology
Background:
- Distal patellar tendon avulsions are uncommon injuries in adolescents.
- Avulsion fractures of the tibial tuberosity are more frequently described.
- Understanding rare injury patterns is crucial for accurate diagnosis and treatment.
Observation:
- A 13-year-old male soccer player experienced bilateral knee injuries after landing from a jump.
- Radiography and MRI revealed bilateral distal patellar tendon avulsions.
- No fractures of the tibial tuberosities or physes were identified.
Findings:
- This case represents a previously undescribed injury pattern: bilateral distal patellar tendon avulsion without physeal or tibial tuberosity fracture.
- Surgical intervention with open repair and internal fixation was performed.
- The patient achieved an excellent functional outcome post-surgery.
Implications:
- This injury shares pathogenetic and treatment similarities with tibial tuberosity avulsion fractures.
- The findings suggest a new subtype of extensor mechanism avulsion injuries in pediatric athletes.
- Further research into this specific injury pattern is warranted to refine understanding and management strategies.
