Earlier research has shown that exercising while receiving manual therapy improves function and reduces pain in people with knee osteoarthritis. However, very little is known about the mechanisms by which manual therapy and exercise reduce pain and improve function. This study will ask subjects with knee osteoarthritis to receive one of the following interventions: (1) no treatment, (2) exercise only, or (3) manual therapy only. Measures will be taken of the patient's knee range of motion, knee swelling and pain before and after receiving the intervention. These measures will be analyzed to determine what effect exercise and manual therapy applied to the knee have on improving knee range of motion and reducing knee pain and swelling. Swelling will be measured using an ultrasound device which is used to take pictures inside the knee. This type of ultrasound measurement is painless and harmless.

Primary Outcome Measures:
  • Suprapatellar effusion measured via diagnostic ultrasound [ Time Frame: Outcome measure will be measured 1 minute prior to intervention and 1 minute after intervention. ]

Secondary Outcome Measures:
  • Pain Visual Analog Scale [ Time Frame: Outcome measure will be measured 3 minutes prior to intervention and 3 minutes after intervention. ]
  • Goniometric knee arc range of motion [ Time Frame: Outcome measure will be measured 5 minutes prior to intervention and 5 minutes after intervention. ]
  • Western Ontario and McMaster Universities Index of osteoarthritis of the knee [ Time Frame: Outcome measure will be measured 12 minutes prior to intervention and 7 minutes after intervention. ]

Enrollment: 1
Study Start Date: October 2009
Study Completion Date: August 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Manual Therapy
Subjects will receive oscillatory (grade 1 & 2) manual knee mobilization for 15 minutes at various knee range of motion positions.
Procedure: Manual Therapy
Grade 1 and 2 oscillatory manual mobilization of the tibiofemoral joint at various ranges of motion.
Experimental: Therapeutic Exercise
Subjects will perform 15 minutes of combined resistance exercise and aerobic exercise.
Behavioral: Therapeutic Exercise
Subjects will perform 5 minutes of lower extremity cycle ergometer with minimal resistance followed by 10 minutes of resistance exercise to the quadriceps at 3 tibiofemoral positions (0 degrees, 30 degrees and 60 degrees of knee flexion).
Placebo Comparator: Control
Subjects will watch a 15 minute instructional video on a health topic.
Behavioral: Video Observation
Subjects will watch a 15 minute video on a health topic unrelated to knee osteoarthritis.
