Abstract

Purpose

Drainage is a common procedure in high tibial osteotomy (HTO), but the benefits of drainage during HTO remain poorly investigated. This study was designed to investigate the effect of drainage on blood loss and early functional recovery in HTO.

Methods

Altogether, 80 patients undergoing HTO were analyzed from August 2018 to September 2019. Patients were randomized into two groups: group A (drainage, n = 40) and group B (no drainage, n = 40). There were no intergroup differences in baseline parameters between the two groups, and the same surgical techniques and haemostatic methods were used. The mean follow-up time was 3.2 months. Blood loss and early functional recovery of the knee were examined post-operatively in both groups.

Results

The total post-operative blood loss was 253.34 ± 104.18 ml in group A and 222.51 ± 106.89 ml in group B. This difference was non-significant (p > 0.05). The post-operative haemoglobin and haematocrit differences between groups were also non-significant (p > 0.05). Post-operative visual analogue scale (VAS) pain scores and lower leg swelling were lower in group A than those in group B (p < 0.05), and the early range of motion of the knee joint was higher in group A than that in group B (p < 0.05). Group A had lower incidence rates of dressing seepage and incision complications than group B (p < 0.05). The differences in three month post-operative VAS and knee function scores were non-significant (p > 0.05).

Conclusion

Drainage in HTO does not increase patients’ total blood loss, but it can promote early knee function recovery by reducing post-operative pain, lower leg swelling, and the incidence of incision complications.
