Summary

The purpose of this research is to develop and test the feasibility of an exercise intervention for persons with painful knee osteoarthritis involving the patella (kneecap). Participants in the patellofemoral osteoarthritis (PFOA) group will be treated with a 6-week supervised exercise program that targets strengthening the hip and trunk core muscles. Painfree control participants will attend one session to gather biomechanical, strength, and function data for use in comparison to the patellofemoral osteoarthritis group. Feasibility outcomes include adherence to the treatment program, recruitment, and retention. It is hypothesized that PFOA group participants will change score on a knee pain and function questionnaire by the minimum clinically important difference score for positive improvement at the end of the 6-week intervention program.

Detailed description

The investigators propose to develop and test the feasibility of a 6-week supervised hip and core muscle exercise intervention for persons with painful patellofemoral osteoarthritis (PFOA), a common condition for middle-aged and older adults. Currently there is limited evidence regarding effective conservative interventions for PFOA, a chronic condition that is painful and limits function and quality of life. Exercise is recommended as a first-line treatment for knee osteoarthritis, but the optimal type of exercise for PFOA is unknown. This intervention is based upon similar programs shown to improve pain and function in younger persons with patellofemoral pain, a condition that may lead to PFOA. Feasibility outcomes include adherence to the treatment program, recruitment, retention, and the impact of the intervention on participants' pain and function at 6-weeks and 6 months after finishing the program. The investigators will also compare PFOA participants to a matched pain-free volunteer control group to explore the differences in their biomechanics, muscle strength, pain report, and function at baseline. Data from this feasibility study will be used to design a future randomized controlled trial investigating the efficacy of conservative exercise interventions for PFOA. The investigators' overarching goal is to develop a conservative exercise intervention that improves the symptoms, function, and quality of life of persons with PFOA.
