Brief Summary:
Hypothesis: Viscosupplementation when combined with an off-loading knee brace is more effective in treating the symptoms of knee OA then treating with viscosupplementation alone

Condition or disease Intervention/treatment Phase
Knee Osteoarthritis Other: Orthovisc Device: DonJoy HA lite knee brace Device: Orthovisc injections and DonJoy HA lite knee brace Not Applicable

Detailed Description:
A randomized prospective study to assess the effectiveness of treating knee osteoarthritis with either a series of three viscosupplementation injections, an off-loading knee brace, or a combination of viscosupplementation and an off-loading knee brace. The viscosupplementation and off-loading knee brace are being used in accordance with their FDA approval. Subjects will be randomized to 1 of 3 treatment groups. The control group will receive a series of weekly (3 consecutive weeks) intra-articular hyaluronic acid injections. The second group will receive a series of weekly (3 consecutive weeks) intra-articular hyaluronic acid injections and an off loading knee brace. The third group will use the off loading knee brace alone. Subjects will complete the WOMAC Osteoarthritis Questionnaire (pain, stiffness, function) and VAS pain scale (measuring pain on movement) at baseline, day 7, day 14, 6 weeks and 3 months. Subjects in group 2 and 3 will be given a brace diary to record compliance.

Arm Intervention/treatment
Viscosupplementation injections
Control group will receive a series of three viscosupplementation injections into the affected knee
Other: Orthovisc
Subjects will receive a series of three Orthovisc injections into their affected knee
Experimental: Off-loading knee brace Device: DonJoy HA lite knee brace
Subjects will be fitted and educated on using the DonJoy HA lite knee brace to treat their affected knee
Experimental: Viscosupplementation and knee brace Device: Orthovisc injections and DonJoy HA lite knee brace
Subjects will receive a series of three Orthovisc injections and be fitted and educated on using a DonJoy HA lite knee brace



Primary Outcome Measures :
  1. Reduction in knee pain [ Time Frame: 3 months ]
    The primary outcome measure will be a reduction in knee pain as measured by the VAS pain score. The secondary outcome measure will be an increase in function as measured by the WOMAC Osteoarthritis Questionnaire.
