Evaluating the Effectiveness of Clinical Practice Guideline Adherence for Patellofemoral Pain

Evaluating the Effectiveness of Clinical Practice Guideline Adherence for Patellofemoral Pain (knEE-CAPP)

Enrollment

440 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Patellofemoral Pain

Summary

The overall goal of this multisite, randomized clinical trial is to evaluate the short- and long-term effectiveness of a Clinical Practice Guideline (CPG)-adherent physical therapy approach to patellofemoral pain (PFP) management among military Service members. The main questions it aims to answer are: 1. Can a CPG-adherent care approach to PFP management improve short- and long-term knee function, pain, and confidence with completing duty-related activities? 2. Can a CPG-adherent care approach to PFP management reduce utilization of healthcare resources and analgesic medication prescription at 12-month follow-up? 3. Are there patient- and care-specific factors that predict or mediate clinical benefit from physical therapy care for PFP? Researchers will compare the CPG-adherent physical therapy intervention to usual physical therapy care in the Military Health System. Participants will: 1) be randomized to receive CPG-adherent care or usual care for PFP management; 2) attend physical therapy corresponding to their group assignment; and 3) complete patient-reported outcome measures at baseline and 6-weeks and 3-, 6-, and 12-months post-randomization.

Eligibility

Min Age: 18 Years

Inclusion Criteria4

Active-duty Service member
Aged ≥18 years
Presence of unilateral or bilateral PFP based on the core criterion of peripatellar and/or retropatellar pain with reproduction of PFP by at least one activity that loads the patellofemoral joint during weight bearing on a flexed knee, such as prolonged sitting, kneeling, squatting, hopping, running, stair climbing, patellar palpation
Available to participate in physical therapy treatment within 6 weeks of initial enrollment

Exclusion Criteria8

Presence of tibiofemoral OA based on imaging evidence in the electronic health records in the past year or self-report
History of patellar or intra-articular knee trauma (e.g., dislocation/fracture) or surgery
History of neurodegenerative conditions that may affect movement patterns (e.g., Multiple Sclerosis)
Meniscal or ligamentous pathologies within the past year based on imaging evidence of acute injury in the electronic health record or self-report
Quadriceps or patellar tendon injuries within the past year based on imaging evidence of acute injury in the electronic health record or self-report
Known pregnancy (pregnant females may be eligible for participation after end of pregnancy and medical clearance by a qualified and licensed healthcare provider)
Receipt of physical therapy care for PFP within the three months prior to enrollment
Known to be pending medical evaluation board, discharge from the military, scheduled deployment, or litigation for an injury at time of enrollment.

Interventions

OTHERClinical Practice Guideline-adherent Care

Clinical examination procedures will be used to identify all appropriate impairment subcategories (Overuse/Overload without Other Impairment, PFP with Movement Coordination Deficits, PFP with Muscle Performance Deficits, PFP with Mobility Impairments) and create a subcategory-specific or multimodal (for patients classified to \>1 subcategory) plan of care. Research physical therapists will target all applicable impairment subcategories using the corresponding CPG-recommended interventions, all of which are recommended for use as part of standard-of-care physical therapy practice. The duration and length of care will not be prespecified or standardized across participants to allow flexibility pending participant's care needs and schedule (e.g., vacation, short-term TDY status); however, research PTs will be trained to target providing no more than 10-12 visits over no more than 6-8 weeks to promote generalizability of the CPG-adherent intervention.

OTHERUsual Care

Usual physical therapy care will be provided by a licensed outpatient staff physical therapist who is not associated with the research team. The outpatient physical therapists will not treat participants in the CPG-adherent group and will be free to treat their participants based on their current personal and organizational clinical practice standards. The research team will neither influence nor restrict the evaluations conducted or interventions provided.
