Reliability of Intraoperative Knee Range of Motion Measurements by Goniometer Compared with Robot-Assisted Arthroplasty
J Knee Surg DOI: 10.1055/s-0038-1641140Accurate measurement of knee range of motion (ROM) is critical to predict the outcomes of knee surgery and prognosis. We investigated the reliability of knee ROM measurements by goniometer compared with robotic system. Fifty-three patients with medial osteoarthritis who were planning to undergo unicompartmental knee arthroplasty (UKA) with robotic UKA were prospectively enrolled. During the operation, knee ROM measurement was performed in both flexion and extension before and after insertion of the implant using both a goniometer and robotic system. The intraclass correlation coefficient (ICC) of extension measured by the goniometer and robotic system showed good agreement; however, the ICC of flexion did not show good agreement. During passive flexion, the mean values measured before insertion of the implant were significantly lower by goniometer (134.6 ± 6.43) than by robot (145.4 ± 6.80; p = 0.017); likewise, the mean values after insertion of the implant were significantly lower by goniometer (138.6 ± 6.07) than by robotic system (147.0 ± 6.60; p = 0.045). A goniometer can underestimate knee ROM measurements compared with robotic system, especially in flexion. Orthopaedic surgeons should be cautious when measuring the flexion angle with a goniometer.

CONCLUSIONS: HA promoted human meniscus regeneration by inhibiting apoptosis, promoting cell migration, and accelerating cell proliferation, potentially through the PI3K/MAPK pathway via the CD44 receptor. PMID: 29658360 [PubMed - as supplied by publisher]
Authors: Song D, Qi W, Lv M, Yuan C, Tian K, Zhang F Abstract Osteoarthritis (OA) is a common type of arthritis, which may cause pain and disability. Alterations in gene expression and DNA methylation have been proven to be associated with the development of OA. The aim of the present study was to identify potential therapeutic targets and associated processes for OA via the combined analysis of gene expression and DNA methylation datasets. The gene expression and DNA methylation profiles were obtained from the Gene Expression Omnibus, and differentially expressed genes (DEGs) and differentially methylated sites (D...

Conclusions: The prevalence of TCM use among eastern Malaysian patients with knee osteoarthritis was high. Physicians caring for these patients should be aware of these findings so that inquiries regarding TCM use can be made and patients can be appropriately counseled. PMID: 29657684 [PubMed]
In this report, we present the case of an intra-articular synovial lipoma in a 58-year-old female with a coincident marked unilateral hip osteoarthritis. This patient suffered from right hip pain that developed gradually over 2 years. Physical examination noted decreased range of motion and evidence of impingement. MR and CT images showed an intra-articular fat-intense mass in the hip joint that was excised and confirmed as a synovial lipoma on histology. This case reveals that an intra-articular lipoma of the hip could be accompanied by pain or impingement and followed by hip osteoarthritis even in the absence of trauma.

This study aims to assess if regions with differences in subchondral bone plate thickness have differences in cartilage thickness when comparing ACL reconstructed (ACLR) knees of women ≥5 years post-injury to contralateral and controls with uninjured knees.

DiscussionThis trial is intended to test the application of GOHT in the chronic management in knee OA. The hypothesis is that OA patients may receive disease management via this network platform conveniently and effectively, especially those in the remote areas of our country. GOHT telemedicine would be an attractive alternative to traditional methods for disease management in knee OA. The results could provide preliminary experiences and guidance for an upcoming full-scale randomized controlled trial (RCT) in disease management via telemedicine.Trial registrationChiCTR:ChiCTR1800014465.

CONCLUSIONS: This study showed that upregulation of Bcl-XL and Mcl-1 expression in RA FLS by CRT were PI3K/Akt and STAT3 signal pathways dependent, and promoted the anti-apoptosis of RA FLS. Therefore, this may represent a therapeutic target for the treatment of RA. PMID: 29652658 [PubMed - as supplied by publisher]
