Background: The survival rate of cemented knee prosthesis depends among other factors on optimal cement-bone contact, nevertheless no standard exists for cementing technique of tibial components. The aim of this study was to determine which tibial surface preparation technique leads to the best bone-cement contact.
Materials And Methods: HUMAN TIBIAL PLATEAU SPECIMENS WERE CLEANED IN FOUR DIFFERENT WAYS BEFORE CEMENTING: a) no cleaning, b) manual syringe irrigation, c) fracture brush cleaning, and d) pulsatile jet-lavage. The specimens were cut into transverse sections and the bone cement contact distance was calculated for every 10 mm and the cement penetration depth was measured. Both values were statistically analyzed (ANOVA).
Results: The longest bone-cement contact (62 mm) was seen after PJL, the shortest (10.6 mm) after no cleaning at all. The deepest cement penetration (4.1 mm) again was seen after PJL, the least (0.7 mm) after no cleaning. Statistically, PJL yielded the longest bone-cement contact and deepest cement penetration.
Conclusion: The results supports the use of pulsatile jet-lavage before cementing tibial components in knee arthroplasty.

Despite an increasing number of studies examining the effect of Single-Photon Emission Computed Tomography/ Computed Tomography (SPECT/CT) on improvement of diagnosis of aseptic loosening, there is still a great deal of uncertainty regarding its applicability in diagnostic algorithm. Therefore, in this meta-analysis, we aimed to investigate the diagnostic performance of SPECT/CT for identification of aseptic loosening in patients with persistent pain following the total knee arthroplasty (TKA) and total hip arthroplasty (THA). Electronic databases including Medline, Scopus, Web of Science, Cochrane library, and Embase were systematically searched for identifying relevant published studies from their inception to April 2023.

The Clarivate Analytics Web of Knowledge database was used to obtain data and metrics of TKA research. The search list was sorted by the number of citations, and articles were included or excluded based on relevance to TKA.

It was hypothesized that patients treated with BCR prostheses would present higher flexion and better clinical and functional results than those treated with PS implants. This prospective study included thirty-two patients treated for primary knee osteoarthritis and assigned to two matched groups for their demographic characteristics and comorbidities.

This study aimed to evaluate the efficacy of antibiotic-loaded cement articulating spacers produced through a silicone mold in the two-stage revision of infected total knee arthroplasty. Five individuals were prospectively treated with 2-stage revision using spacers made by this mold. Clinical assessment was conducted during and after implantation using the WOMAC Score, Oxford knee score, and range of motion (ROM).

Background: This study aims to explore the impact of the National Volume-based Procurement Policy in Guangdong Province on hospitalization costs for total knee arthroplasty inpatients.
Methods: Interrupted time-series analysis were used to examine the expenses associated with total knee arthroplasty for inpatients at a hospital in Guangzhou between May 10, 2021, and December 26, 2023. The period was divided into two phases based on the implementation of the policy, the pre-policy phase (May 10, 2021, to April 30, 2022) and the post-policy phase (May 1, 2022, to December 26, 2023).
