Harnessing Raman spectroscopy and multimodal imaging of cartilage for osteoarthritis diagnosis.

Osteoarthritis (OA) is a complex disease of cartilage characterised by joint pain, functional limitation, and reduced quality of life with affected joint movement leading to pain and limited mobility. Current methods to diagnose OA are predominantly limited to X-ray, MRI and invasive joint fluid analysis, all of which lack chemical or molecular specificity and are limited to detection of the disease at later stages. A rapid minimally invasive and non-destructive approach to disease diagnosis is a critical unmet need.

A comparison of postoperative microbiological and histological test results with the indication for revision as listed at the time of surgery in the National Joint Registry: a single-centre cohort study of metal-on-metal total hip replacement and hip resurfacing revision procedures.

Introduction: Surgeons allocate an indication(s) for revision surgery on NJR Minimum Data Set forms in the immediate perioperative period, when results from intraoperative histology and microbiology samples are not available. We evaluated to what extent the postoperative diagnostics obtained for patients undergoing metal-on-metal hip arthroplasty (MoMHA) revision surgery align with the indication for revision listed in the NJR.

Methods: NJR data for MoMHA revision patients (2004-2015) at a single centre were linked to hospital records of microbiology and histology testing for prosthetic joint infection (PJI) and adverse reaction to metal debris (ARMD).

Holistic vibrational spectromics assessment of human cartilage for osteoarthritis diagnosis.

Osteoarthritis (OA) is the most common degenerative joint disease, presented as wearing down of articular cartilage and resulting in pain and limited mobility for 1 in 10 adults in the UK [Osteoarthr. Cartil.28(6), 792 (2020)10.
