Lead Sponsor
Qilu Hospital of Shandong University
Brief Summary

The objective of this study was to evaluate the safety and efficacy of topical combined with intravenous tranexamic acid for high tibial osteotomy without placement of a drainage tube The clinical scores of patients and their possible risks were tracked. The investigators hypothesized that a combination of tranexamic acid and no drainage tube could reduce blood loss and facilitate early recovery. The implementation of the study will provide a new perioperative blood loss control program for High Tibial Osteotomy, reduce the cost of hospitalization, promote patients to get out of bed early, reduce the number of days in hospital.

Detailed Description

The condition of the patients was evaluated, and the total length of both lower limbs, anteroposterior position of knee and Mri of knee were included. The preoperative dose of tranexamic acid was calculated according to body weight of 20 mg / kg, 100 ml of tranexamic acid sodium chloride solution was dripped 30 minutes before operation, and after incision closure, 30 ml of normal saline solution containing 2 g of tranexamic acid was injected through drainage tube or subcutaneously. Postoperative intravenous drip of 100 ML sodium chloride solution containing 20 mg / kg tranexamic acid. Arthroscopy was first used to further confirm the cartilage defect, and a new type of lower limb alignment meter and a customized precise osteotomy template were used to perform the osteotomy according to the preoperative plan. One group was not placed drainage tube, the other group was placed drainage tube. Visual analogue pain score (Vas) and American Special Surgical Hospital (HSS) knee function score were recorded 3 month after surgery. Throughout the trial, the investigators will carefully observe and manage your complications and the outcome of your surgery.

Primary Outcome Measures
NameTimeMethod
HaemoglobinThe third day after operation

Reactive blood loss

Visual Analogue Scale Postoperative Day OnePostoperative Day One

Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.

Volume of drainagePostoperative Day One

Reactive blood loss

Hospital for special surgery knee scorepostoperative 3 month

HSS is a knee function scoring system with a full score of 100. 0 means the loss of knee function, 100 means the best knee function, and the greater the value, the better knee function.

Visual Analogue Scale Postoperative Day ThreePostoperative Day Three

Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.

Visual Analogue Scale Postoperative Day FivePostoperative Day Five

Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.

Number of delayed healing of the incision.On the 14th day after operation

On the 14th day after operation, the incision did not heal.

Postoperative blood lossThe third day after operation

Total blood loss preoperative blood volume =(preoperative hematocrit-postoperative Hematocrit) + transfusion volume.

Circumference of shank Postoperative Day ThreePostoperative Day Three

indirectly reflects the latent blood loss

Number of blood transfusionsPostoperative Day Three

If the hemoglobin was \<80 g/l, allogeneic blood was transfused, and the number of blood transfusions were recorded.0 means no blood transfusion, and the larger the number is, the more blood transfusion.The maximum number does not exceed the total number of patients

Number of hematoma formationpostoperative 3 month

After operation, the incision is swollen and has wave motion, but it is not hot or painful, and there will be blood outflow during puncture.

Number of Incision infectionpostoperative 3 month

The incision was red, swollen, hot and painful, and the blood routine showed that the leukocyte was increased.
