Overview

Mission

The knee society operates to promote outstanding care to patients with knee disorders through innovative research and education.

What it reported doing in 2025

Educational events are designed to provide practicing orthopaedic surgeons with current information regarding disorders of the knee, surgical and non-surgical treatments for the knee, and emerging technology. Scientific papers and symposia will present information on total knee arthroplasty to engance the care of patients with painful, arthitic knee joints. The society also provides members with the ability to organize various educational seminars and lectures provided on interim basis.

Operating model

Revenue model
Earned-program. 89% of the money available for current operations came from fees and other program revenue.
Distribution model
Direct operator. The filing allocates 97% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Expenses are high relative to revenue and some filed totals do not add up.
