Summary
Pediatric patellar malalignment surgery effectively corrected knee alignment in most cases. Different surgical techniques showed varied success rates, with specific methods excelling at correcting patellar tilt or lateral deviation.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Biomechanical Analysis
Background:
- Patellar malalignment is a common condition in children, potentially leading to pain and functional limitations.
- Surgical intervention is often considered for persistent or severe cases of pediatric patellar malalignment.
Purpose of the Study:
- To evaluate the effectiveness of three different surgical techniques for correcting patellar malalignment in pediatric patients.
- To compare the outcomes of lateral release, lateral release with medial reefment, and Roux-Goldthwait patellar tendon transposition.
Main Methods:
- A retrospective review of 57 pediatric knee surgeries performed between 1985 and 1991.
- Assessment of pre- and post-operative roentgenographic values using Laurin's method.
- Evaluation of outcomes based on Insall's criteria at a mean follow-up of 4 years 2 months.
Main Results:
- Overall, 40 out of 57 knees achieved excellent or good outcomes.
- Significant improvement in roentgenographic values and correction of patellar malalignment were observed.
- Lateral release with medial reefment was most effective for patellar tilt, while Roux-Goldthwait corrected lateral patellar deviation.
Conclusions:
- Surgical realignment is effective in correcting pediatric patellar malalignment.
- The choice of surgical technique should be tailored to the specific type of malalignment (tilt vs. lateral deviation).
- Lateral release may be suitable for cases of mild patellar malalignment.
