Abstract:
Introduction: Medial open wedge high tibial osteotomy
(MOWHTO) is one of the modalities to treat
unicompartmental knee osteoarthritis (KO). Many studies
have shown good outcomes of MOWHTO, but there are no
published series of Malaysian patients. The aim of this study
is to determine the outcome of MOWHTO in primary medial
compartment KO in a university teaching hospital in
Malaysia.
Materials and methods: This is a retrospective study of
patients who underwent MOWHTO in our Joint
Reconstruction Unit between 2017 and 2022 with a
minimum of 12 months follow-up.
Results: Data from a total of 15 knees were reviewed. The
mean age of patients was 41.8 years, and the mean BMI was
31.7. The mean Kellgren-Lawrence (KL) osteoarthritis grade
was 2.87 (±0.52). The mean hip knee angle (HKA) preoperatively was 12.26° varus and post-operatively was 3.33°
valgus. Mean correction of HKA was 13.59°. The results
revealed an improvement in all patients, as observed from
the significant mean difference between pre-operative
(38.53) and post-operative (77.60) Knee Injury and
Osteoarthritis Outcome (KOOS) (p-value<0.001) scores.
Patients who were above 50 years old showed a significantly
better improvement in KOOS score compared to those below
50 (p-value <0.05). There was no significant difference
observed between BMI and KOOS score improvement (Fstat=0.580, p-value >0.05).
Conclusion: MOWHTO is a good treatment option in
medial compartment primary KO with varus deformity
among Malaysian population. A larger sample size with a
longer follow-up period is needed to draw a definitive
conclusion
