Brief Summary

Patients with PFPS demonstrate quadriceps and hip musculature weakness, altered lower extremity (LE) kinematics, and decreased LE flexibility. Psychosocial factors have also been identified as an important factor in patients with PFPS. The authors hypothesize that an ordered approach addressing each of these impairments sequentially will result in greater improvement in PFPS symptoms. The results of the investigators pilot study assessing the feasibility of using a sequential approach showed a full randomized controlled trial is warranted, the authors now plan to proceed with a full trial. The objective of this study is to assess the efficacy of a sequential approach in the treatment of Patellofemoral Pain Syndrome. Methods: Patients will be randomized to a sequential treatment approach using a PFPS treatment algorithm (PFPS Algorithm) designed by the authors or typical physical therapy care. Due to the constant evaluation necessary no blinding will be performed. Patients will attend therapy two times per week for six weeks. Pain, Anterior Knee Pain Scale (AKPS), and Global Rating of Change (GROC) will be measured at evaluation and discharge, 3 month follow-up and 6 month follow-up.

Outcome Measures

Primary Outcomes (1)

  • Change in Anterior Knee Pain Scale

    Assessment of change of the Anterior Knee Pain Scale (AKPS). The AKPS is a self-reported 13 item questionnaire with discrete categories related to various levels of current knee function. Categories within each item are weighted, and responses are summed to provide an overall score of 0-100, with 100 representing no disability. The Anterior Knee Pain Scale is found to be valid and reliable in patients from 12-50 years of age presenting with anterior knee pain with a test-retest reliability of .95 (Watson, 2005). A change of 10 points represent the minimal clinical difference (Crossley, 2004).

    Baseline, 3 weeks (18-24 days post-evaluation), 6 weeks (39-46 days post-evaluation), 3 months and 6 months

Secondary Outcomes (2)

  • Change in Numeric Pain Rating Scale

    Baseline, 3 weeks (18-24 days post-evaluation), 6 weeks (39-46 days post-evaluation), 3 months and 6 months

  • Global Rating of Change Scale (GROC)

    Baseline, 3 weeks (18-24 days post-evaluation), 6 weeks (39-46 days post-evaluation), 3 months and 6 months

Study Arms (2)

Impairment based approach

ACTIVE COMPARATOR

The intervention will address the patients impairments found during evaluation. Treatment will based on the Physical therapist evaluation and will be individualized to each patient.

Other: Impairment based approach

PFPS algorithm

EXPERIMENTAL

The Patellofemoral Syndrome algorithm is designed to determine what deficits a patient may have and addressing these sequentially. This subgrouping first assesses a patient fear avoidance beliefs, flexibility, body mechanics, and then strength and functional ability. The reason for sequential treatment is that there is evidence that without adequate flexibility a patient will be unable to perform exercises with proper body mechanics, and without proper mechanics strengthening and functional activity can cause increased stress on the patellofemoral joint. Progression through each specific subgroup is based on objective goals. Once the patient has met these goals they are progressed to the next treatment subgroup until discharge.

Other: PFPS Algorithm approach

Interventions

This intervention will consist of exercise, mechanics training, education, manual therapy and modalities. The treatment will address the impairments found during the evaluation. This approach is a typical individualized physical therapy treatment approach.

Impairment based approach

Physical Therapy treatment for Patellofemoral Pain Syndrome based upon a treatment algorithm that addresses patients: fear avoidance beliefs, flexibility, body mechanics, and strength. The exercises and treatments are individualized to each patient with the goals of low fear avoidance beliefs, flexibility, body mechanics, and strength and are performed in a sequential manner
