[High tibial osteotomy for gonarthrosis (author's transl)]

Area of Science:

• Orthopedic surgery
• Knee joint biomechanics
• Osteoarthritis treatment

Background:

• Knee osteoarthritis often presents with axial deformities.
• Tibial osteotomy is a surgical option for correcting these deformities.
• Proximal tibial osteotomy aims to realign the knee joint.

Purpose of the Study:

• To evaluate the clinical outcomes of proximal tibial osteotomy.
• To assess the efficacy of a single staple for internal fixation.
• To determine the suitability of this procedure for specific patient populations.

Main Methods:

• Retrospective analysis of 54 proximal tibial osteotomies performed between 1971 and 1975.
• Focus on clinical results, pain relief, and complication rates.
• Evaluation of internal fixation methods, specifically single staple use.

Main Results:

• Significant pain relief was observed following deformity correction.
• A low incidence of complications was reported.
• Internal fixation with plates or other devices was deemed superfluous.
• A single staple facilitated early movement and weight-bearing.

Conclusions:

• Proximal tibial osteotomy is a successful treatment for knee osteoarthritis with axial deformity.
• Single staple fixation is sufficient, allowing for early mobilization.
• The procedure is particularly advantageous for elderly patients, including those with cardiovascular disease.
• Salvage procedures and joint replacement remain viable options in cases of osteotomy failure.
