High Tibial Osteotomy in Unicompartmental Knee Osteoarthritis in the Physiologically Fit Young Elderly Population: A Prospective Case–Control Study with 2-year Follow-up from a Tertiary Care Centre
Kaunteya Ghosh, Malhar ChoksiAbstract
Background:
High tibial osteotomy (HTO) is offered to young active and male individuals with unicompartmental knee arthrosis. The
Purpose:
To assess the efficacy of HTO in the “physiologically young elderly population” compared to the classic cohort.
Setting:
Tertiary care hospital in Kolkata: urban population.
Materials and Methods:
A total of 50 patients [25 elderly {aged 60–75 years} and 25 (aged 45–55 years)] satisfying the classical criteria for HTO – medial compartmental arthritis, no vascular deficit, no significant deformity and no history of rheumatoid arthritis – underwent lateral-based closed-wedge HTO. The patients were evaluated based on preoperative and postoperative Visual Analogue Scale (VAS) and Knee Society Scores (KSS). The elderly had no prior systematic illness, no history of knee trauma, were engaged in exercises and performed a satisfactory treadmill mill test.
Results:
Patients had similar VAS and KSS preoperatively. Younger patients showed better KSS scores up to 6-month follow-up, but both groups had similar VAS scores. At the 1st and 2nd year follow-up, both had similar KSS and VAS.
Conclusion:
Elderly patients showed similar results following HTO as the traditional patients at the 1–2-year follow-up.
