Background
Patients suffering from chronic kidney disease are at greater risk of perioperative and postoperative complications. There is no systematic review study demonstrating whether total joint arthroplasty can be safely performed in patients with chronic kidney disease.
Methods
A literature search was performed in the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and Cochrane Library databases for information from the earliest date of data collection to September of 2018. Studies comparing the perioperative and postoperative outcomes of no–chronic kidney dysfunction (CKD) patients with those of CKD patients were included. Statistical heterogeneity was quantitatively evaluated by means of the χ2 test, with significance set at P < .10 or I 2 > 50%.
Results
Three articles consisting of 38,209 patients were included (35,363 no-CKD patients and 2,846 CKD patients). The results showed that CKD was related to a greater increase in postoperative infection rate, deep vein thrombosis, readmission, and mortality (P < .1). No differences in length of surgery, length of stay, pulmonary embolism, or revision were observed (P > .10).
Conclusions
Compared with no-CKD patients, CKD patients demonstrated an increased risk of perioperative and postoperative complications.
Artificial Dermis Composite Tissue Flaps versus Traditional Prefabricated Flaps
Comparison of Repair Characteristics
Objective
We compared the application of artificial dermis composite tissue flaps and traditional prefabricated flaps in a rat model of exposed bone and tendon injury.
Methods
Sprague Dawley rats were randomly divided into two groups (n = 40 per group). Group A rats received artificial dermis composite tissue flaps and group B rats received traditional prefabricated flaps. Flap appearance, range of motion, degree of swelling, tissue histologic results, and imaging findings were compared between groups at 7, 14, 21, and 28 days.
Results
There was no difference in flap appearance, range of motion, or degree of swelling between groups. However, blood perfusion of the artificial dermis composite tissue flap was better than that of the traditional prefabricated flap; the artificial dermis was also found to be thicker than the traditional prefabricated flap.
Conclusions
The artificial dermis composite tissue flap is an ideal method for repairing exposed bone and tendon, and it displays repair effects comparable with those of the traditional prefabricated flap and may be a better alternative.
