Summary
Retro-tubercle opening-wedge high tibial osteotomy is a promising technique for genu varum, showing fewer patellar tendon issues and tibial slope changes compared to medial opening-wedge osteotomy.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Knee Osteotomy
Background:
- Traditional genu varum treatments have complications.
- Retro-tubercle opening-wedge high tibial osteotomy is an emerging surgical option.
Purpose of the Study:
- Compare retro-tubercle opening-wedge high tibial osteotomy with medial opening-wedge osteotomy for genu varum.
- Evaluate postoperative changes in patellar tendon length and tibial plateau inclination.
Main Methods:
- Randomized controlled trial with 72 patients.
- Groups: retro-tubercle (n=34) vs. medial (n=38) opening-wedge osteotomy.
- Pre- and postoperative assessment of patellar position, tendon length, and tibial slope.
Main Results:
- Retro-tubercle group showed no significant patellar tendon shortening.
- Medial group demonstrated significant patellar tendon shortening (P≤.05).
- Medial group had significant tibial plateau inclination changes; retro-tubercle group did not.
Conclusions:
- Retro-tubercle opening-wedge high tibial osteotomy may offer advantages over medial opening-wedge osteotomy.
- The retro-tubercle technique appears to preserve patellar tendon length and tibial slope better.
