Abstract
Purpose
There have been several reports on the incidence of deep venous thrombosis (DVT) following medial open wedge high tibial osteotomy (OWHTO). However, the prevention and treatment of DVT in this context remain subjects of debate and controversy. Therefore, our study aimed to investigate the incidence of DVT during the early postoperative period after OWHTO performed at our institution. By focusing on this specific timeframe, we hoped to better understand the risks associated with the procedure and the need for potential preventive measures.
Subjects and Methods:
The study included 87 patients, corresponding to 92 knees, who underwent OWHTO at our institution between 2016 and 2023. The average age of the patients was 60.2 years, and the average body mass index (BMI) was 26.8 kg/m². Importantly, no prophylactic anticoagulants were administered to these patients. DVT was assessed using lower limb vein ultrasonography, typically conducted on average 4.2 days after surgery to determine the presence of thrombotic events.
Results
DVT was detected in 41 cases, representing an incidence rate of 47.1%. All identified cases were asymptomatic distal DVTs, with 38 cases (43.7%) occurring on the operated side and 3 cases (3.4%) affecting both legs. No DVT occurrences were observed on the contralateral, non-operated side. Moreover, there was no statistically significant difference in the 6-month postoperative clinical outcomes between the DVT group and the non-DVT group, suggesting that the presence of DVT did not significantly impact short-term recovery.
Discussion
In line with various reports from other studies, our findings indicate a high incidence of DVT following OWHTO. This underscores the importance of vigilant perioperative management to mitigate the risk of DVT, even when patients remain asymptomatic. Our study highlights the need for careful monitoring and possibly reconsideration of current practices regarding anticoagulation therapy, particularly in light of the potential risks associated with DVT in the postoperative period.
