About this study

The purpose of this study is to assess the effectiveness of using a 3D medical assessment device versus usual care to help guide clinical decisions about the management of PFP. The objective is to determine if gathering objective biomechanical data from a three-dimensional (3D) motion capture device leads to more precise and optimal care, ultimately improving physical function and other outcomes compared to participants who receive routine care that is not guided by information from this device.

Participants will be recruited from primary care and physical therapy clinics at participating sites. Authorized study personnel will search electronic medical records (Genesis) to identify potential study participants diagnosed with knee pain.

After consent and enrollment, participants will complete baseline measures and then receive a Knee Kinesiography exam. The participant will be entered into the KneeKG system using a unique participant identifier. After the knee kinesiography exam with the KneeKG, participants will be randomized 1:1 into one of two different treatment arms: 1) KneeKG informed care or 2) usual care without any information from the KneeKG.

Knee mechanics during gait is assessed with a Knee Kinesiography exam. The participant will walk for 5 minutes on a commercial treadmill at their comfortable speed. Three-dimensional (3D) knee kinematics are captured on each leg using the KneeKG system (Emovi, Canada). With this validated FDA cleared medical device, there is an accurate quantification of specific knee biomechanical markers during gait in a clinical setting. There will be two 45-second trials to electronically capture the data which is immediately accessible through automatic reports. Biomechanical markers captured include but are not limited to varus/valgus alignment at stance, varus/valgus alignment at heel strike, knee flexion angle at heel strike, total knee excursion in sagittal plane, tibial rotation at heel strike and throughout gait cycle. The entire procedure will take approximately 15-20 minutes. This procedure will occur at baseline and also again at 12 weeks.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age 18-50
  • Active Duty Service Member stationed at Fort Liberty and Schofield Barracks
  • Diagnosis of patellofemoral pain (ICD-10 codes: M25.2 (pain in unspecified knee), M25.561 (pain in right knee), and M25.562 (pain in left knee)

Exclusion criteria

  • Pregnancy
  • Known to be leaving that duty station within next 3 months
  • Concurrent lower limb injuries (examples include but are not limited to ankle sprain or HS strain)
  • Previous knee surgery
  • History of traumatic knee injury, such as a ligament tear or meniscal tear
  • Presence of rheumatoid or neurological disease

Treatment and study plan

Emovi Knee Kinesiography

Device

All participants will receive a KneeKG exam. This device will capture three-dimensional knee kinematics for a participant's knee, using the KneeKG system. Therapists will use these reports and suggested exercises to guide their care for participants in the Intervention group.

Other names: KneeKG

Primary outcomes

  1. Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function

    Time frame: 12 weeks

    PROMIS asks patients about their functional ability, and symptoms. This tool is designed as a health-focused rather than a disease-focused measurement system. The primary outcome measure will focus on the the Physical Function domains since PFPS is known to limit function during daily and sports & recreation activities. This is an adaptive questionnaire that is taken in RedCap and contains up to 166 questions that will not all be asked, scored 1-5 on a Likert scale based on limits of function.

    The primary outcome is the between-group difference in PROMIS Physical Function T-score at 3 months. A linear mixed effects model will be used to analyze the between-group differences across the various time points (repeated measures).

Secondary outcomes

  1. Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference

    Time frame: 12 weeks

    This PROMIS tool focuses on pain interference in daily life. This questionnaire is adaptive taken in RedCap and contains up to 41 questions that will not all be asked. It is scored on a 5 point Likert scale based on limitation due to pain.

  2. Anterior Knee Pain Scale (AKPS)

    Time frame: 12 weeks

    The Anterior Knee Pain Scale is a 13-item more specific questionnaire related to PF pain which will allow to assess pain and symptoms during specific loading-activities. The 13 items on the scale are used to assess subjective symptoms and functional restrictions. A score can have a minimum of 0 points or a maximum of 100 points. Athletes would receive a score of 100 if they showed no signs of anterior knee pain.

  3. Self-Reported Readiness to Return to Duty

    Time frame: 12 weeks

    The Self-Reported Readiness to Return to Duty questionnaire consists of three questions to assess perceived readiness to return to duty

  4. Total Lost Duty Days

    Time frame: 12 weeks

    Tracking the amount of duty days a soldier missed while enrolled in protocol.

  5. Provider Satisfaction

    Time frame: 12 weeks

    A provider satisfaction survey will be used to measure patient satisfaction with quality of physical therapy care.
