Conversion to Total Knee Arthroplasty After High Tibial Osteotomy: A Systematic Review and Meta-analysis

Loke RWK, et al. · Orthopaedic Journal of Sports Medicine

Conversion to total knee replacement: 4.5% before 5 years, 8.3% at 5-10 years, 11.2% beyond 10 years; overall complications 12.1%. Adding cartilage repair procedures showed no significant survival benefit in pooled data.

Population

5,162 HTO patients across 59 studies

Intervention

High tibial osteotomy

Comparator

None (pooled conversion rates)

Limitations

Heterogeneous techniques and eras pooled; the null finding for concomitant cartilage repair conflicts with smaller controlled series.
