A Special Report: Osteoarthritis of the Knee

Keeping Aging Adults Active

This CME activity was planned and produced in accordance with the Essential Areas and Policies of the Accreditation Council for Continuing Medical Education (ACCME). The American College of Sports Medicine (ACSM) is accredited by the ACCME to sponsor continuing medical education for physicians. The ACSM takes responsibility for the content, quality, and scientific integrity of this CME activity.

The ACSM designates this educational activity for a maximum of 2 hours in category 1 credit towards the American Medical Association Physician's Recognition Award. Each physician should claim only those hours of credit that he/she actually spent in the educational activity.

To participate in this program, you must read the material carefully, answer the test questions, obtain a passing grade (a minimum score of 60% must be obtained), and complete the credit evaluation form.

VISA, MasterCard, Discover, and American Express will be accepted for all online self-test registrations. If you prefer to mail your payment and self-test answer form, please print out the mail-in form. Note: All international participants MUST utilitze the mail-in form.

After answering the test questions, go to the end of this test to score your exam. To receive credit verification, fill out the form confirming you have read the materials and obtained a minimum passing score.

After reading the learning objectives, select the best answer for each of the following questions.

Learning Objectives:

Read the article The Osteoarthritic Knee (print, page 6)
and learn to:

  • Understand the basic pathophysiology of osteoarthritis of the knee.
  • Identify risk factors associated with osteoarthritis of the knee.
  • Efficiently and effectively evaluate a patient presenting with osteoarthritis of the knee.
Read the article Nonoperative Management of Osteoarthritis of the Knee (print, page 14)
and learn to:
  • Understand the nonoperative therapies available for treating osteoarthritis of the knee.
  • Understand that all of these modalities modify symptoms only. They do not alter the osteoarthritic disease process.
  • Recognize the role that viscosupplementation can play as the most recent addition to the osteoarthritis treatment armamentarium.
  • Understand the need for development of osteoarthritis treatment algorithms predicated on evidence-based studies.
Read the article Operative Treatment Options for Osteoarthritis of the Knee and Cartilage Defects (print, page 20)
and learn to:
  • Identify the operative therapies available for treating osteoarthritis of the knee.
