Single-Stage Reverse High Tibial Osteotomy and Total Knee Arthroplasty for Valgus Extra-Articular Deformity After Failed HTO: A Matched-Pair Pilot Study
Matched-pair pilot study evaluates outcomes of reverse high tibial osteotomy with total knee arthroplasty.
Key Points
This study aims to assess the outcomes of simultaneous reverse high tibial osteotomy during total knee arthroplasty in patients with prior valgus deformity.
Retrospective matched-pair study comparing nine patients undergoing reverse HTO and TKA to a primary TKA control group.
Assessment of radiographic parameters (MPTA, mLDFA, aHKA, JLO) and clinical scores (Oxford Knee Score, LEFS, KOOS, TAS, FIPS) pre- and postoperatively.
Statistical significance set at p < 0.05.
Preoperative alignment significantly differed between groups (p ≤ 0.001 for MPTA, aHKA, JLO).
Postoperatively, both groups achieved neutral mechanical alignment with no significant differences (all p > 0.05).
Clinical scores were numerically close between groups, though wide confidence intervals limited definitive conclusions.
