The effect of a preoperative education class on the rate of manipulation under anesthesia after total knee arthroplasty in a veterans population.

ABSTRACT:

Background

Arthrofibrosis after total knee arthroplasty (TKA) is a common complication, potentially occurring in up to 25% of patients, and may be treated during the early recovery period by manipulation under anesthesia (MUA). The majority of preoperative factors that predispose patients to postoperative stiffness are patient specific and not modifiable. The United States Veteran Affairs is a particularly challenging group given a higher baseline rate of medical comorbidities and opioid dependence than the general population. Patient education about postoperative expectations and complications has been shown to improve outcomes in certain orthopedic procedures. This retrospective study aims to determine if preoperative counseling for veterans undergoing primary TKA reduces the rate of postoperative stiffness, and consequently MUA, in this subset of patients.

Methods

We evaluated the medical records of 244 veterans at a single veteran affairs hospital who underwent 278 TKAs during a 6-year period under one surgeon. Patients were separated into groups based on attendance in the preoperative counseling session. Effects of various factors, including age, sex, body mass index, preoperative knee range of motion, and history of previous knee surgery, were compared between these 2 cohorts.

Results

Attendance in the preoperative course did not have a statistically significant impact on the rate of manipulation (odds ratio [OR], 1.07). Female gender and prior manipulation had an increased OR of knee manipulation, whereas age > 65 years had a decreased OR that did not reach significance.

Conclusions

Our results show that preoperative counseling did not have a benefit in terms of postoperative MUA rates in veterans. Preoperative education may be helpful for setting appropriate expectations of pain, recovery, and function after total joint arthroplasty and may be useful in an online or video format in small practices in which cost may be prohibitive. Further studies are needed to determine whether they provide any benefit in postoperative arthrofibrosis rates.

Project description:ObjectiveTo compare the blood loss, transfusion rates and complications between the aspirin and non-aspirin group in unilateral and bilateral total knee arthroplasties (TKAs) with a nested case-control design.MethodsThe present study retrospectively selected TKA cases from the Joint Arthroplasty Database at the Peking Union Medical College Hospital from January 2014 to December 2019 following strict inclusion and exclusion criteria, and divided them into the aspirin and non-aspirin group based on the use of aspirin preoperatively. Bleeding was measured by blood loss, transfusion rate, drainage volume, hemoglobin (HGB) and hematocrit (HCT), while complications (cardiovascular events, venous thromboembolism events, cerebrovascular events and wound events) were compared between the groups. Student's unpaired t-test and Mann-Whitney U-test were used to compare the differences of continuous variables between the two groups while chi-square test and Fisher's exact test were applied in categorical variables.ResultsA total of 560 patients with unilateral TKA and 285 patients with bilateral TKA were extracted. Among these, 280 patients used aspirin preoperatively. No other differences were found in demographic and surgical characteristics between the two groups except for the proportion of coronary artery diseases (P < 0.001). For primary outcomes, there was no significant higher blood loss and transfusion rate in the aspirin group, while the drainage of aspirin group was higher than the control group in bilateral TKAs (P = 0.043). The HGB and HCT of the aspirin group was significant lower in both unilateral and bilateral TKAs at POD5 (P < 0.05). For complications, there was a lower vascular related complication rate in aspirin group after unilateral TKAs (P = 0.040), but the wound event rate in aspirin group was higher than the control group (P = 0.049).ConclusionsPreoperative use of aspirin could prevent vascular related events during the perioperative period of TKA. However, it might also increase the risk of bleeding and wound complications.
