QR 0.07 degrees) (PS) to 1.634 degrees (IQR 1.08 degrees) (TRI) at G3. Statistical analysis revealed significant differences among the test groups for position (G0 P<.001; G1 P<.05; G2 P<.001; G3 P<.001) and direction (G0 P<.005; G1 P<.001; G2 P<.001; G3 P<.001).

Without soft tissue interference, the accuracy of certain digital scanning systems was comparable with that of the conventional impression technique. The amount of flexible soft tissue interference affected the accuracy of the digital scans.

The angled screw channel concept has become popular. Protein Tyrosine Kinase inhibitor However, research is lacking as to how reverse torque values of nonaxially tightened implant crowns compare with axially tightened cement-retained crowns restored on angle-correcting abutments when subjected to long-term cyclic loading.

The purpose of this invitro study was to evaluate the ability of different 25-degree angled screw channel hexalobular systems to apply the target torque value on their screws, the effect of cyclic loading on their reverse torque values, and their survival compared with crowns cemented on conventional 0-degree screw channel abutments.

A total of 28 implants were divided into 4 groups. Twenty-one angled screw channel crowns were fabricated at a 25-degree angle correction by using angled titanium (Ti) bases by 3 manufacturers DY (Dynamic Tibase), DE (AngleBase), and ASC (Angulated Screw Channel) (n=7). The fourth group, UB (Universal Base, Control), had cement-retained crowns with 25-degree custom-milled, angled zirconia -to-failure survival of all groups was similar. Fractures at the zirconia to titanium base connection were seen with ASC crowns.
The hexalobular system of DY delivered comparable initial torque values to its target value at 25 degrees, similar to how UB (control group) delivered at 0 degrees. ASC and DE scored lower initial torque values than their target value compared with UB. The DY abutment, which had a lower manufacturer recommended torque value, had lower reverse torque values compared with those of other groups. Time-to-failure survival of all groups was similar. Fractures at the zirconia to titanium base connection were seen with ASC crowns.
The relationship between surgeon and hospital charges and reimbursements for revision total knee arthroplasty (TKA) has not been well examined. The objective of this study is to report trends and variations in hospital charges and payments compared to surgeons for stage 1 (S1) vs stage 2 (S2) septic revision TKA and aseptic revision (AR) TKA.

The 5% Medicare sample was used to capture hospital and surgeon data for revision TKA from 2005 to 2014. The charge multiplier (CM) and ratio of hospital to surgeon charges, and the payment multiplier (PM) and ratio of hospital to surgeon payments were calculated. Year-to-year variation and regional trends in-patient demographics, Charlson Comorbidity Index, length of stay (LOS), CM, and PM were evaluated.

In total, 4570 AR, 1323 S1, and 863 S2 TKA patients were included. CM increased for all cohorts 8.1-13.8 for AR (P < .001), 21.0-22.5 (P= .07) for S1, and 11.8-22.0 (P < .001) for S2. PM followed a similar trend, increasing 8.1-13.8 (P < .001) for AR, 19.8-27.3 (P= .005) for S1, and 14.7-30.7 (P < .001) for S2. Surgeon reimbursement decreased for all cohorts. LOS decreased for AR (3.8-2.8 days), S1 (12.8-6.9 days), and S2 (4.5-3.9 days). Charlson Comorbidity Index remained stable for AR patients but increased significantly for S1 and S2 cohorts.

Hospital charges and payments relative to the surgeons have significantly increased for revision TKA in the setting of stable or increasing patient complexity and decreasing LOS.

Long-term survival of metal-on-metal (MoM) prostheses and the development of adverse reaction to metal debris (ARMD) around these bearings are still unclear. Serum levels of cobalt (Co) and chromium (Cr) are used as a screening tool to anticipate failure in MoM bearings and detect ARMD.

One hundred sixty primary large head MoM prostheses were followed up for 10 years. To estimate the revision risk, the cumulative incidence function (CIF) was used. Subdistribution hazard modeling was used to investigate the associations between cumulative incidence of revision for ARMD and Co levels, Cr levels, gender, age, head size, and cup inclination. Furthermore, the safe upper limits (SULs) for Co and Cr were determined.

Univariate analyses showed an increased risk in revision for ARMD in females (subdistribution hazard ratio [sdHR] 3.43, 95% confidence interval [CI] 1.01-11.7, P= .049) and cup inclination angles over 45° (sdHR 4.70, 95% CI 1.63-13.58, P= .004). In addition, a higher last measured Co level (sdHR 1.05, 95% CI 1.03-1.07, P < .001) and last measured Cr level (sdHR 1.21, 95% CI 1.14-1.29, P < .001) were associated with a higher probability of revision for ARMD. We determined our bearing-specific SULs at 4.1 parts per billion (ppb) and 4.2 ppb for Co and Cr, respectively.

Guidelines regarding follow-up and surveillance should include a complete clinical assessment with bearing-specific SULs of serum metal ion levels. For the M2a-Magnum MoM bearing we advise an SUL for Co and Cr levels of 4.1 and 4.2 ppb, respectively.

Studies have shown that lower socioeconomic status may result in adverse outcomes following total hip (THA) and total knee arthroplasty (TKA). The optimal method of defining socioeconomic status, however, continues to be debated. The purpose of this study is to determine which socioeconomic variables are associated with poor outcomes following THA and TKA.

We reviewed a consecutive series of 2770 primary THA and TKA patients from 2015 to 2018. Utilizing census data based upon the patient's ZIP code, we extracted poverty, unemployment, high school graduation, and vehicle possession rates. We collected demographics, comorbidities, discharge disposition, 90-day readmissions, and postoperative functional outcome scores for each patient. We then performed a multivariate regression analysis to identify the effect of each socioeconomic variable on postoperative outcomes.

Patients from areas with high unemployment (P= .008) and low high school graduation rates (P= .019) had a higher age-adjusted Charlson Comorbidity Index.
