Summary
This study on injection-induced quadriceps contractures in children found that Judet arthromyolysis surgery improved knee flexion by 70 degrees, though 50% of patients had active extension deficits post-surgery.
Area of Science:
- Pediatric Orthopaedics
- Musculoskeletal Disorders
Background:
- Injection-induced contractures of the quadriceps are a known complication in pediatric patients.
- These contractures can significantly impair knee joint mobility and function.
Purpose of the Study:
- To evaluate the outcomes of surgical intervention for injection-induced quadriceps contractures in children.
- To analyze the effectiveness of arthromyolysis according to Judet, with or without distal quadriceps reconstruction.
Main Methods:
- A retrospective follow-up study of 8 cases (7 patients) with injection-induced quadriceps contractures.
- Surgical treatment involved arthromyolysis according to Judet, with or without distal quadriceps reconstruction.
- Mean follow-up duration was 9 years.
Main Results:
- A mean increase in passive knee flexion of 70 degrees was achieved.
- 50% of patients experienced a deficit in active knee extension post-operatively.
- The study discusses clinical diagnosis, therapeutic options, and surgical outcomes.
Conclusions:
- Judet arthromyolysis is an effective surgical option for improving passive knee flexion in injection-induced quadriceps contractures.
- Active extension deficits remain a potential complication requiring further consideration and management strategies.
