This study establishes normal passive (PROM) and active (AROM) range of motion values for pediatric knee joints. These findings are crucial for diagnosing and treating knee injuries and disorders in children.
Area of Science:
- Pediatric Orthopedics
- Biomechanics
- Sports Medicine
Background:
- Pediatric knee injuries stem from accidents, sports, and underlying medical conditions affecting mobility.
- Accurate assessment of pediatric knee range of motion (ROM) is essential for diagnosis and treatment.
- Existing data on pediatric knee ROM, particularly considering diverse ethnicities, may be limited.
Purpose of the Study:
- To determine normative values for passive (PROM) and active (AROM) range of motion in the pediatric knee.
- To investigate the influence of anthropometric and demographic factors on pediatric knee ROM.
- To provide reference data for clinical evaluation and safety analyses.
Main Methods:
- Collected data on passive and active knee range of motion from 295 children in the UAE.
- Analyzed data considering factors such as age, gender, and ethnicity (Arab and South Asian).
- Examined correlations between anthropometric measurements and knee joint ROM.
Main Results:
- Established average PROM values for boys (131.2°) and girls (132.8°), and for children (132.2°) versus adolescents (130.8°).
- Established average AROM values for boys (129.3°) and girls (130.5°), and for children (130.2°) versus adolescents (128.6°).
- Identified significant ethnic variations and anthropometric correlations impacting pediatric knee ROM.
Conclusions:
- The study provides crucial normative data for pediatric knee passive and active range of motion.
- Findings highlight the importance of considering ethnicity and anthropometry in pediatric knee assessments.
- These values aid in evaluating knee impairments and improving outcomes for pediatric knee injuries.

Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
Range Rule of Thumb to Interpret Standard Deviation
For instance, the range rule of thumb can be used to find the tallest and the shortest student in a class, given the mean student height and standard deviation. If the mean student height is 1.6 m and the standard deviation, s is 0.05 m, the height...
