Dianne Bryant, University of Western Ontario, Canada Identifier:
First received: June 4, 2012
Last updated: February 6, 2013
Last verified: February 2013
Participants will be randomized to undergo a High Tibial Osteotomy (HTO) with or without a knee scope. Patients will be tested in the Gait Lab, will fill out quality-of-life questionnaires, and have a clinical evaluation done preoperative and at each follow-up visit.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:
