Abstract Background Periprosthetic femoral fracture (PFF) is a serious complication after total knee arthroplasty (TKA). However, the risk factors of PFF in the early postoperative setting are not well documented. This study determines the risk factors of early PFF after primary TKA. Methods This study recruited 24 patients who had early PFF within postoperative 3 months and 96 control patients. Demographic data (age, gender, weight, height, body mass index, Deyo-Charlson comorbidity index, diagnosis, operated side, underlying diseases and history of steroid usage intraoperative outcomes), intraoperative outcomes (operative time, surgical approach, type and brand of the prosthesis), and radiographic outcomes (distal femoral width; DFW, prosthesis-distal femoral width ratio; PDFW ratio, anatomical lateral distal femoral angle; LDFA, the change of LDFA, femoral component flexion angle; FCFA and anterior femoral notching; AFN) were recorded and compared between groups. Details of PFF, including fracture pattern, preoperative deformity, and time to PFF were also documented. Results In univariate analysis, the PFF group had significantly older, right side injury, rheumatoid, dyslipidemia, Parkinson patients than the control group (p < 0.05). No cruciate-retaining design was used in PFF group (p = 0.004). Differences between the prosthetic brand used were found in this study (p = 0.049). For radiographic outcomes, PFF group had significantly lower DFW but higher PDFW ratio and postoperative LDFA than the control group (p < 0.05). While the change of LDFA, FCFA and AFN were similar between groups. The fracture patterns were medial condylar (45.8%), lateral condylar (25.0%) and supracondylar fracture (29.2%). The mean overall time to PFF was 37.2 ± 20.6 days (range 8–87 days). Preoperative deformity was significantly different among the three patterns (p < 0.05). When performed multivariate analysis using the logistic regression model, age was only an independent risk factor for early PFF. The cut-off point of age was > = 75 years, with a sensitivity of 75.0% and specificity of 78.1%. Conclusion This study determined that age was the independent risk factors for early PFF. However, further well-controlled studies with a larger sample size were needed to address this issue.

AbstractIntraoperative fracture of the proximal tibia is a rare complication of total knee arthroplasty (TKA) with few studies available reporting risk factors or prognosis. A review of our prospective joint registry was performed to determine the incidence and associated risk factors of intraoperative tibia fractures during primary TKA; 14,966 TKAs of all manufacturers were performed with 9 intraoperative tibia fractures. All fractures occurred in a single TKA design. There were 8,155 TKAs of this design performed with a fracture incidence of 0.110%. All but one fracture occurred on the medial tibial plateau, and all but one occurred during preparation of the tibia with keel punching. A control group of 75 patients (80 knees) with the same TKA design were randomly selected. Baseplates size 3 or smaller were less likely to experience an intraoperative fracture (odds ratio [OR]: 0.864, 95% confidence interval [CI]: 0.785–0.951), as were knees with a polyethylene insert thickness of 13 mm or larger (OR: 0.882, 95% CI: 0.812–0.957). Fractures were treated with a variety of different methods, but every patient had at least one screw placed and most (67%) had postoperative weight-bearing restrictions. At final follow-up, there were no cases of nonunion, component subsidence, or need for reoperation. Intraoperative tibia fractures are a rare complication of this TKA design at 0.11%. Knees with baseplates of size ≤3 and polyethylene thickness ≥13 mm were less likely to experience intraoperative fracture. These findings may be related to the depth of tibial resection, requiring the use of a thicker polyethylene insert, and a change in the keel width in implants size 4 or larger. No fracture patients required reoperation.

AbstractSince the 2016 implementation of the comprehensive care for joint replacement (CJR) bundled payment model, our institutions have sought to decrease inpatient physical therapy (PT) costs by piloting a mobility technician program (MTP), where mobility technicians (MTs) ambulate postoperative total knee arthroplasty (TKA) patients under the supervision of nursing staff members. MTs are certified medical assistants given specialized gate and ambulation training by the PT department. The aim of this study was to examine the economic and clinical impact of MTs on the primary TKA postoperative pathway. We performed a retrospective review of TKA patients who underwent surgery at our institution between April 2018 and March 2019 and who were postoperatively ambulated by MTs. The control group included patients who had surgery during the same months of the prior year, preceding introduction of MTs to the floor. Inclusion criteria included: unilateral primary TKA for arthritic conditions and conversion to unilateral primary TKA from a previous knee surgery. Minitab Software (State College, PA) was used to perform the statistical analysis. There were 658 patients enrolled in the study group and 1,400 in the control group. The two groups shared similar demographics and an average age of 68 (p = 0.177). The median length of stay (LOS) was 2 days in both groups (p = 0.133) with 90.5% of patients in the study group discharged to home versus 81.5% of patients in the control group (p < 0.001). The ability of MTs to increase patient discharge to home without negatively impacting LOS suggest MTs are valuable both clinically to patients, and economically to the institution. Cost analysis highlighted the substantial cost savings that MTs may create in a bundled payment system. With the well-documented benefits of early ambulation following TKA, we demonstrate how MTs can be an asset to optimizing the care pathway of TKA patients.

This non-randomized control group intervention study was conducted to determine the effect of preoperative video based pain training on postoperative pain and analgesic use in patients undergoing total knee arthroplasty. During the study, the patients in the control ( n = 40) received routine care and the patients in the intervention group ( n = 40) received video based pain training. İt was determined that the mean postoperative pain scores of the intervention group were significantly lower and their pain management was better compared to the control group ( p < .05). The intervention group was found to use significantly less paracetamol on operation day compared to the control group ( p < .05). The intervention group was determined to benefit from non-pharmacological methods more than the control group did ( p < .05). Providing video based pain training to patients undergoing total knee arthroplasty is recommended since it reduces postoperative pain levels and increases the use of non-pharmacological pain control methods.

AbstractShort CommunicationsSevere post-operative pain is common after total knee arthroplasty. Patient-controlled analgesia is an alternative method of pain management, whereby a patient administers his or her own pain medication. Patients seem to prefer this method over nurse-administered analgesia. However, it remains unclear whether patients using patient-controlled analgesia devices use higher or lower doses of opioids compared to patients treated with oral opioids.Objectives and MethodsThis retrospective study examined 164 patients undergoing total knee arthroplasty. Post-operatively, 82 patients received oxycodone via intravenous patient-controlled analgesia devices, while the pain medication for 82 patients in the control group was administered by nurses. The main outcome measure was the consumption of intravenous opioid equivalents within 24 h after surgery. Secondary outcome measures were the use of anti-emetic drugs and the length of stay. Furthermore, we evaluated opioid-related adverse event reports.ResultsThe consumption of opioids during the first 24 h after surgery and the use of anti-emetic drugs were similar in both groups. The median opioid dose of intravenous morphine equivalents was 41.1 mg (interquartile range (IQR): 29.5–69.1 mg) in the patient-controlled analgesia group and 40.5 mg (IQR: 32.4–48.6 mg) in the control group, respectively. The median length of stay was 2 days (IQR: 2–3 days) in the patient-controlled analgesia group and 3 days (IQR: 2–3 days) in the control group (p=0.02). The use of anti-emetic drugs was similar in both groups.ConclusionsThe administration of oxycodone via intravenous patient-controlled analgesia devices does not lead to increased opioid or anti-emetic consumptions compared to nurse-administered pain medication after total knee arthroplasty. Patient-controlled analgesia might lead to shortened length of stay.
