Summary
High tibial osteotomy effectively treats early medial knee osteoarthritis, with most patients showing no radiographic progression and satisfactory outcomes after over a decade. Many return to high-activity lifestyles.
Area of Science:
- Orthopedic surgery
- Knee osteoarthritis research
- Biomechanical engineering
Background:
- Medial knee osteoarthritis is a common degenerative joint disease.
- High tibial osteotomy (HTO) is a surgical option for younger patients with medial knee osteoarthritis.
- Long-term outcomes of HTO for early-stage gonarthrosis require further investigation.
Purpose of the Study:
- To evaluate the long-term clinical and radiographic outcomes of high tibial osteotomy in patients with early medial gonarthrosis.
- To assess the functional status and return to activity levels in patients post-HTO.
Main Methods:
- A cohort of 27 patients (28 knees) with Ahlbäck's Stage I medial gonarthrosis underwent high tibial osteotomy.
- Patients were followed for a median of 11 years (range 7-18 years).
- Clinical outcomes (satisfaction, activity levels) and radiographic progression were assessed.
Main Results:
- At a median of 11 years post-surgery, 22 out of 28 knees were rated as satisfactory.
- Nine patients were able to manage high-activity sports or heavy work.
- Radiographic progression of osteoarthritis was not observed in 25 out of 28 knees.
Conclusions:
- High tibial osteotomy demonstrates durable clinical and radiographic success for early medial knee osteoarthritis.
- The procedure allows many patients to maintain high functional levels and return to demanding activities.
- HTO is a viable treatment option for preserving knee function in young to middle-aged adults with medial compartment knee osteoarthritis.
