Summary
Localized knee growth arrest is treatable with surgical excision if less than 50% of the physis is affected and 2.5 cm of growth potential remains. Corrective osteotomy is recommended for deformities over 20 degrees.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Skeletal growth and development
Background:
- Management of localized physeal (growth plate) arrest in pediatric patients.
- Understanding the criteria for surgical intervention and concurrent procedures.
Observation:
- Surgical excision is indicated for localized growth arrest around the knee when less than 50% of the physis is involved.
- A minimum of 2.5 cm of remaining skeletal growth is necessary for this intervention.
- Angular deformities exceeding 20 degrees necessitate simultaneous corrective osteotomy.
Findings:
- The efficacy of different interposition materials (fat, cartilage, elastomer, methylmethacrylate) following excision is not definitively established.
- Excision is a viable option for specific cases of localized physeal arrest.
Implications:
- Provides clear surgical guidelines for treating localized knee growth arrest, optimizing outcomes.
- Highlights the need for further research into optimal interposition materials to improve post-operative results.
- Informs orthopedic surgeons on patient selection and procedural planning for physeal growth disturbances.
