NCT02003976

Brief Summary

The purpose of this study is to compare patients with knee osteoarthritis (OA) receiving optimized non-surgical treatment plus surgical realignment of the tibia, or optimized non-surgical treatment only. We hypothesize that outcomes assessed at 12 and 24 months follow-up will suggest favourable changes in patients undergoing surgical realignment when compared to patients receiving non-surgical treatment only.

Study Arms (2)

Non-Surgical Treatment plus HTO

EXPERIMENTAL

The optimized non-surgical treatment program consists of medications, physiotherapy and nutritional seminars. The 12-week program will include an assessment by a primary care physician, physiotherapist and orthopaedic surgeon, one supervised physiotherapy session per week, one body recomposition session per week, and a home program. After the 12-week program is completed, patients randomized to this group will undergo a medial opening wedge high tibial osteotomy (HTO). They will continue with their home program and will be followed up for 2 years after baseline.

Interventions

A lower limb realignment surgery to redistribute load away from the most affected portion of the knee.

Eligibility Criteria

Age25 Years - 55 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Is the subject either:
  • years old?
  • Older than 55 but still active (ex. physical labour, regular recreational activities)?
  • Does this subject present with varus alignment? (Based on hip to ankle x-rays).
  • Does this subject have clinical Knee OA? (MAA \<-2° on full limb standing AP) according to the Altman classification primarily involving the medial compartment of the knee?
  • Patient is a good candidate for high tibial osteotomy and will be receiving a PEEK plate, or if receiving an alternate plate, agrees to have the plate removed prior to 1 year postoperative.

You may not qualify if:

  • Has this subject had a previous HTO or joint replacement in either limb?
  • Is this subject likely to undergo bilateral HTO within the 2 year follow up period?
  • Does this subject have an unstable knee or ligament?
  • Does this subject have inflammatory or infectious arthritis of the knee?
  • Radiographic disease too advanced for HTO (ie. diffuse lateral compartment, patellofemoral joint OA and/or severe enough disease to suggest that joint replacement is the better surgical option) and/or Kellgren and Lawrence grade 4.
  • The subject's disease is not advanced enough (symptomatically or radiographically) to warrant HTO.
  • Does this subject have a major medical illness with life expectancy \<2 years or with an unacceptably high operative risk?
  • Does this subject have a major neurological deficit that would affect gait?
  • Is this subject possibly pregnant or planning pregnancy?
  • Is this subject unable to read English?
  • Does this subject have a psychiatric illness that limits informed consent?
  • Is the subject unlikely to comply with study protocol?
