Outcome Measures

Primary Outcomes (5)

  • Kujala Knee Score

    13 item questionnaire to rate pain, function, ambulation, and instability

    10 minutes

  • Tegner Activity Scale

    11 levels of activity from complete inability to function to advanced sports participation

    5 minutes

  • Isokinetic Strength using Biodex

    Force of movement is measured in newtons and torque and corrected for body weight

    30 minutes

  • Passive Range of Motion

    Measured with goniometer to record full range of motion in knee flexion and extension

    5 minutes

  • Edema Assessment

    Measure of knee circumference

    2 minutes

Secondary Outcomes (1)

  • Numerical Pain Rating Scale

    1 minute

Study Arms (2)

Immobilization

ACTIVE COMPARATOR

Patients in this group will be given a knee immobilizer to wear for 2 weeks and then receive outpatient physical therapy evaluation and treatment

Other: Early Range of MOtion

Early range of motion

EXPERIMENTAL

Patients in this group will be allowed to move the knee and start outpatient physical therapy and treatment immediately.

Other: Early Range of MOtion

Interventions

Groups will be compared to see if immobilization or early range of motion is better at returning to their sport after patellar dislocation.

Also known as: Immobilization, Ear;y Range of Motion

Eligibility Criteria

Age11 Years - 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Male and female adolescents between 11-17 years
  • Medical diagnosis of 1st time lateral patellar instability episode (dislocation or subluxation)
  • Subjective history of knee shifting, instability, popping out, knee effusion
  • Apprehension test is positive and has medial patellar tenderness
  • Referred to the Texas Children's Hospital (TCH) outpatient sports medicine clinic from an emergency room facility, urgent care or pediatrician within 10 days of the injury.
  • Free of co-morbidities that would prevent or limit rehabilitation including cardiac, pulmonary, psychiatric (except Attention Deficit Disorder (ADD) or Attention Deficit Hyperactivity Disorder (ADHD), orthopedic, neurological
  • Must be able to follow directions and participate in rehabilitation protocol for the 3-month study period.

You may not qualify if:

  • Imaging or clinical findings suggest surgical intervention is needed i.e. fracture, osteochondral defect, Lachman or other positive knee ligament special tests.
