AI Article Synopsis
- The study systematically reviewed and analyzed the outcomes of robotic-assisted vs. conventional unicompartmental knee arthroplasty (UKA) to compare complication and revision rates.
- A total of 16 studies involving over 50,000 patients showed that robotic-assisted UKA had significantly fewer complications and lower revision rates compared to the conventional method.
- Despite these findings, the study notes limitations that affect the reliability of the results, indicating the need for further research in this area.
Article Abstract
Objective: We conducted this systematic review and meta-analysis of studies on patients who underwent unicompartmental knee arthroplasty (UKA) to compare the complication rates, revision rates and non-implant-specific complications between robotic-assisted and conventional UKA.
Design: Systematic review and meta-analysis.
Data Sources: The PubMed, Embase, Web of Science and Cochrane databases were searched up to 30 June 2020.
Eligibility Criteria: Case-control studies comparing robotic-assisted and conventional UKA.
Data Extraction And Synthesis: Data from all eligible articles were independently extracted by two authors. We analysed the differences in outcomes between robotic-assisted and conventional UKA by calculating the corresponding 95% CIs and pooled relative risks (RRs). Heterogeneity was assessed using the χ and I tests. All analyses were performed using the 'metafor' package of R V.3.6.2 software.
Results: A total of 16 studies involving 50 024 patients were included in the final meta-analysis. We found that robotic-assisted UKA had fewer complications (RR: 0.52, 95% CI: 0.28 to 0.96, p=0.036) and lower revision rates (RR: 0.42, 95% CI: 0.20 to 0.86, p=0.017) than conventional UKA. We observed no significant differences in non-implant-specific complications between the two surgical techniques (RR: 0.80, 95% CI: 0.61 to 1.04, p=0.96). No publication bias was found in this meta-analysis.
Conclusions: This study provides evidence that robotic-assisted UKA has fewer complications and lower revision rates than conventional UKA; however, owing to important limitations, the results lack reliability, and more studies are required.

The Risk of Postoperative Periprosthetic Femoral Fracture After Total Hip Arthroplasty Depends More on Stem Design Than Cement Use: An Analysis of National Health Data from England.
J Bone Joint Surg Am
January 2025
Leeds Institute of Health Sciences, School of Medicine, University of Leeds, Leeds, West Yorkshire, England.
Background: In this study, we estimated the risk of surgically treated postoperative periprosthetic femoral fractures (POPFFs) associated with femoral implants frequently used for total hip arthroplasty (THA).
Methods: In this cohort study of patients who underwent primary THA in England between January 1, 2004, and December 31, 2020, POPFFs were identified from prospectively collected revision records and national hospital records. POPFF incidence rates, adjusting for potential confounders, were estimated for common stems.
Interim Results of Rigicon Penile Prosthesis Implantation in a Single Center: The Largest Series in Türkiye.

Department of Urology, Medistate Kavacık Hospital, İstanbul, Türkiye.
Objective: To analyze data from patient information forms (PIFs) submitted to the manufacturer of a new 3-piece inflatable penile prosthesis (IPP), the Rigicon Infla10® , to summarize interim outcomes of 250 implantations in a single center, which is the largest series in Türkiye.
Methods: A retrospective review of PIFs from 250 patients implanted with the IPP between January 2021 and December 2023 was performed to assess patient characteristics, surgical data, device durability, patient satisfaction, and rates of reoperation for any reason.
Results: The mean ± SD (range) follow-up was 21.
Cement-within-cement technique in revision reverse total shoulder arthroplasty: complications, reoperations, and revision rates at 5-year mean follow-up.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN, USA.
Background: Revision reverse total shoulder arthroplasty (rTSA) of a previously cemented humeral component is challenging. In hip arthroplasty, the cement-within-cement (CwC) technique has been well described as an effective option. However, for shoulder arthroplasty there remains a paucity of data investigating this technique.

Background: Reverse total shoulder arthroplasty (rTSA) is an increasingly common procedure for proximal humerus fractures (PHFs), but postoperative complications have not been well characterized. The purpose of this systematic review is to assess complications and revision rates following rTSA in the management of PHFs as documented in current literature.
Methods: A systematic review was performed on primary rTSA for PHFs.
