Association between changes in muscle strength and pain in persons with meniscal tear and osteoarthritis.

ABSTRACT:

Objective

Strengthening-based physical therapy (PT) is frequently recommended for persons with knee osteoarthritis (OA) and meniscal tear. On average, knee OA patients experience pain improvement while undergoing PT, but whether these changes are accompanied by changes in muscle strength remains an important research question.

Design

We used data from subjects randomized to PT in the Meniscal Tear in Osteoarthritis Research (MeTeOR) trial. Key elements, measured at baseline and 3 months, included quadriceps and hamstrings strength (in pounds) and Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain subscale (0-100; 100 worst). We examined the linear association between change in strength and change in pain over 3 months.

Results

111 subjects (mean age 57.1, averag
