High tibial osteotomies: indications and techniques

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering

Background:

• Unicompartmental medial or varus knee gonarthrosis (osteoarthritis) is a common condition.
• A well-maintained range of motion is crucial for patient selection.
• High tibial osteotomy (HTO) is a joint-preserving surgical technique.

Purpose of the Study:

• To discuss the rationale, definition, and techniques of high tibial osteotomies.
• To highlight the advantages and limitations of HTO.
• To review advancements in HTO surgical methods.

Main Methods:

• Review of current literature on high tibial osteotomies.
• Discussion of indications, advantages, and disadvantages.
• Analysis of newer surgical techniques and outcomes.

Main Results:

• HTO is indicated for unicompartmental knee gonarthrosis with preserved motion.
• Advantages include bone stock preservation and realignment.
• Newer techniques offer less invasive surgery, rigid fixation, and improved accuracy.
• HTO provides temporary pain relief with an overall survival of 8-10 years.
• Conversion to total knee arthroplasty may be technically demanding but yields similar long-term results.

Conclusions:

• High tibial osteotomy is a valuable joint-preserving option for specific knee osteoarthritis patients.
• Advancements in HTO techniques enhance surgical outcomes and patient recovery.
• Patients should be counseled on the temporary nature of HTO and the potential need for future knee replacement.
