Relationship of total and regional lean body mass with knee pain and function in patients with knee osteoarthritis: a cross-sectional study.

ABSTRACT:

Background

Lean body mass is crucial for maintaining muscle strength, particularly in patients with knee osteoarthritis. While it provides a protective effect against knee pain and functional decline, the specific relationship between total and regional lean body mass and knee pain and function in these patients remains unclear. This study aimed to investigate the relationship between total and regional lean body mass, and knee pain and function in patients with knee osteoarthritis, with subgroup analyses conducted based on BMI and sex.

Methods

A total of 337 patients were included in the analyses. Clinical information and participant demographics were described descriptively. Linear regression analyses were conducted to investigate the relationship between total and regiona
