Further study details as provided by University of Campinas, Brazil:

Primary Outcome Measures:
  • Clinical based bone union time [ Time Frame: after 8 weeks ]

Secondary Outcome Measures:
  • X-ray femoro-tibial angle [ Time Frame: 6 months, 1 year ]

Estimated Enrollment: 44
Study Start Date: April 2006
Study Completion Date: April 2009
Primary Completion Date: April 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
autologous bone graft
Procedure: high tibial osteotomy
addition of bone graft to fill the osteotomy gap
Other Name: opening-wedge higi tibial osteotomy
Experimental: 2
without bone graft
Procedure: higi tibial osteotomy
the gap of the tibia is unfilled
Other Name: opening-wedge higi tibial osteotomy

Detailed Description:
Opening-Wedge High Tibial Osteotomy is a classic procedure,but the use of autologous bone graft from iliac crest causes pain and bleeding. Bone union occur even without bone graft, but no clinical trials compared results of the twoo procedures.
