Uncemented mobile bearing designs in medial unicompartmental knee arthroplasty (UKA) have seen an increase over the last decade. However, there are a lack of large-scale studies comparing survivorship of these specific designs to commonly used cemented mobile and fixed bearing designs. The aim of this study was to evaluate the survivorship of these designs. A total of 21,610 medial UKAs from 2007 to 2018 were selected from the Dutch Arthroplasty Register. Multivariate Cox regression analyses were used to compare uncemented mobile bearings with cemented mobile and fixed bearings. Adjustments were made for patient and surgical factors, with their interactions being considered. Reasons and type of revision in the first two years after surgery were assessed.Aims

This single-blinded randomised controlled trial
investigated whether one design of mobile-bearing (MB) total knee replacement
(TKR) has any advantage over a fixed-bearing (FB) design on long-term
fixation as measured by radiostereometry. The amount of wear underneath
the mobile bearing was also evaluated. A series of 42 knees was randomised
to MB or FB tibial components with appropriate polyethylene inserts
and followed for between ten and 12 years, or until the death of
the patient. The polyethylene in the MB group was superior in that
it was gamma-irradiated in inert gas and was calcium-stearate free;
the polyethylene in the FB group was gamma-irradiated in air and
contained calcium stearate. In theory this should be advantageous
to the wear rate of the MB group. At final follow-up the overall
mean migration was 0.75 mm (. sd. 0.76) in the MB group and
0.66 mm (. sd. 0.4) in the FB group, with the FB group demonstrating
more posterior tilt and the MB group more internal rotation. In
the FB group there was one revision for aseptic loosening, but none
in the MB group. There were no significant differences in clinical
or radiological scores. . For the MB group, the mean linear wear rate on the under-surface
was 0.026 mm/year (. sd. 0.014). This was significantly smaller
than the wear rate of 0.11 mm/year (. sd. 0.06) in the MB

The aim of this study was to evaluate the differences in revision and complication rates, functional outcomes, and radiological outcomes between cemented and press-fit humeral stems in primary anatomical total shoulder arthroplasty (TSA). Materials and Methods. A comprehensive systematic review and meta-analysis was conducted searching for studies that included patients who underwent primary anatomical TSA for primary osteoarthritis or rheumatoid arthritis. Results. There was a total of 36 studies with 927 cemented humeral stems and 1555 press-fit stems. The revision rate was 5.4% (95% confidence interval (CI) 3.9 to 7.4) at a mean of 89 months for cemented stems, and 2.4% (95% CI 1.1 to 4.7) at a mean of 40 months for press-fit stems. A priori subgroup analysis to control for follow-up periods demonstrated similar revision rates: 2.3% (95% CI 1.1 to 4.7) for cemented stems versus 1.8% (95% CI 1.4 to 2.9) for press-fit stems. Exploratory meta-regression found that longer follow-up was a moderating variable for revision (p = 0.003). Conclusion. Cement
