Trends and Complications of Arthroscopic-Assisted Tibial Plateau Fracture Fixation: A Matched Cohort Analysis

Abstract

Purpose To determine trends in arthroscopic-assisted tibial plateau fracture fixation (AATPFF), to evaluate trends in the overall rate of tibial plateau fracture fixation, and to compare postoperative complications between AATPFF and traditional tibial plateau fixation. Methods A retrospective review of patients undergoing AATPFF and traditional tibial plateau fixation was conducted using the Humana Inc. administrative database from 2007 to 2016. A 1:1 propensity match was utilized to match patients in the 2 study groups based on age, sex, obesity, diabetes, hypertension, chronic obstructive pulmonary disease, depression or anxiety, and smoking history. Postoperative complications were grouped as minor medical complications, major medical complications, surgical complications, emergency department visits, and reoperation. Linear regression analysis was used to assess trends and Pearson’s χ 2 test was used to compare postoperative complications with statistical significance defined as P < .05. Results In total, 522 patients underwent AATPFF and 3920 patients underwent traditional tibial plateau fracture fixation. There was a 4-fold increase in the use of AATPFF over the study period ( P = .0173). Similarly, there was an increase in the utilization of traditional tibial plateau fracture fixation, although to a lesser extent (1.33-fold). After propensity matching, the traditional fixation group demonstrated significantly higher rates of minor medical complications (8.2% vs 2.7%, P = .0002), major medical complications (9.9% vs 4.6%, P = .0018), surgical complications (13.2% vs 2.7%, P < .0001), and emergency department visits (21.4% vs 13.5%, P < .0001) within 90 days of surgery compared with the AATPFF group. There was no difference in reoperation rates within 90 days between the 2 groups (2.9% vs 3.6%, P = .85). Conclusions The incidence of tibial plateau fracture fixation is increasing, however, use of AATPFF is increasing at a faster rate compared to traditional techniques. Furthermore, the addition of knee arthroscopy to fracture fixation does not increase the risk of complication, reoperation, or emergency department visit within 90 days.

Posteromedial Buttress Plate for Schatzker 6 Fractures as Double Column Fixation

“…Therefore, tibial plateau fractures are now commonly classified according to the threecolumn theory using 3D CT together with the Schatzker classification, and fixation is planned accordingly. A posteromedial fragment in CT scan warrants fixation (8,10,11) .…”

“…One of the main advantages of the posteromedial buttress plate fixation technique is that it provides support to the medial column of the tibia, which is an important weight-bearing structure in the lower extremity (10) . By restoring the structural integrity of the medial column, the technique can help promote early weight-bearing and facilitate early rehabilitation (11) .…”

Clinical efficacy and safety of surgery combined with 3D printing for tibial plateau fractures: systematic review and meta-analysis

“…At present, 3D printing technology can reconstruct the tibial platform fracture form into 1:1 physical entity model through computer data, so that clinicians can clearly observe the degree of joint surface damage and the plane fracture collapse position of the tibial platform, and avoid unnecessary soft tissue dissection and reduce postoperative incision complications (30). In addition, 3D printing preoperative planning can also assist clinicians to accurately design the surgical approach of fracture treatment, choose the appropriate internal fixed steel plate, pre-corrected steel plate radian, design screw track and the needle injection position of the external fixed device, so as to obtain more accurate surgical results and improve the fracture reduction quality and operation stability, more vivid realization of preoperative conversation communication with patients and their families, and the price is low, is conducive to patients to receive surgical treatment, so as to improve the compliance with the treatment process (31).…”
