Abstract
Background: Several surgical procedures have been mentioned to treat medial compartment osteoarthritis (OA), as total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO).
Objectives: The aim of the study is a systematic review & meta analysis conducted to compare the outcomes between UKA & HTO in different types of patients diagnosed as an isolated medial compartment OA who treated with UKA or HTO and statistically compare between their results of pain, range of motion, complications, and incidence of revision to TKA using studies published between 2009 to 2019 from any country.
Patients and Methods: The review will be restricted to RCTs, clinical trials, and comparative studies, either prospective or retrospective, which studied the outcome of HTO versus UKA of isolated medial compartment osteoarthritis patients, articles published in English &published during 2009 to 2019.
Results: About 150 articles were found using search keywords. By filtration and screening of the title and exclusion of unrelated articles, about 60 articles were found. By applications of all inclusion and exclusion criteria, only 12 articles were fit to undergo this meta-analysis.
Conclusion: In conclusion, there were no significant differences in the pain score, knee score, complication rate and revision rate to TKA between HTO and UKA, while the HTO group manifested superior ROM compared to the UKA group. So, HTO may be convenient for patients with high activity requirements. Over time, both groups exhibited increased revision rates with the deteriorated clinical outcomes. Therefore when deciding on a therapeutic plan, the ability to revise these failed choices of treatment to a total knee arthroplasty should be a major consideration. This may assist surgeons in their choice. Based on the findings of current meta-analysis, it appears that the two groups have the same efficiency and safety in the treatment of medial knee OA.
