2. No brace group
Inclusion Criteria:
* Age 30-80.
* History of medial unicompartmental knee pain \> 3 months duration (medial compartment only).
* Narrowing of medial joint space \< one half of lateral compartment

* Mild to moderate limitation in Activities of Daily Living (ADL's) and/or recreational activities.
* Must read and understand English language and demonstrate the ability and willingness to follow the protocol and complete the questionnaires and diaries.
* Manual dexterity sufficient to perform all tasks required of study participants.
* Willingness to wear the brace a minimum of 4 hours per day.
Exclusion Criteria:
* Arthritides other than osteoarthritis.
* Previous high tibial osteotomy of the affected knee.
