“…Implants were evaluated in three planes and the presence of osteolysis and/or synovitis was confirmed in at least two planes of imaging. MRI is well-documented in its ability to discern abnormal synovial patterns [8,42] and is an accepted imaging modality for this purpose. Intermediate to decreased signal intensity in the synovial lining with distension of the joint capsule was indicative of reactive synovitis [7,39].…”

Background Little is known about intraarticular pathology following THA prior to the radiographic appearance of osteolysis, primarily due to imaging limitations. MRI has recently been applied to imaging the postarthroplasty hip with the ability to detect periarticular bony and soft tissue pathology; specifically, it is able to detect abnormal synovial patterns and focal bone loss well before the radiographic appearance of osteolysis. Questions/purposes We therefore used MRI to determine the incidence of early reactive synovitis and osteolysis in asymptomatic patients after THA, and whether there is an association between these MRI findings and clinical outcomes or radiographic wear measurements at this early stage. Methods We recruited 31 patients (33 hips) who underwent routine noncemented THA with one of three types of bearing surfaces: metal-on-cross-linked polyethylene (n = 7), ceramic-on-ceramic (n = 12), and ceramic-on-cross-linked polyethylene (n = 14). Patients underwent specialized MRI at a minimum of 12 months (mean, 23 months; range, 12-37 months) after surgery. MR images were analyzed for the presence of synovitis or osteolysis. WOMAC scores, patient assessment questionnaires, and radiographic wear measurements were correlated with MRI findings. Results Reactive synovitis was observed in 13 of 33 patients (39%) and focal osteolysis in one of 33 (3%). The presence of synovitis did not correlate with pain, activity level, patient satisfaction or clinical outcome scales, nor did it correlate with radiographic wear measurements at early followup. Conclusions Our observations suggest reactive synovitis is common yet asymptomatic at short-term followup. We do not know either the etiology or the long-term implications of these observations.

“…Arthroscopy served as a gold standard to which MRI 174,175 and ultrasound [176][177][178][179] were compared, including descriptions of simultaneous use of ultrasound and arthroscopy to assess synovitis. 180,181 An example of another arthroscopy-directed assessment that cannot be duplicated by an ultrasound-guided procedure, the oxygenation state of the synovial membrane was measured using the Lidox probe, developed to assess brain tissue.…”

Conditions prompting physicians and surgeons first adapting endoscopes to peer into joints were mainly the sort of synovial conditions that would concern today's rheumatologists. Rheumatologists were among the pre‐World War II pioneers developing and documenting arthroscopy. The post‐War father of modern arthroscopy, Watanabe, found rheumatologists among his early students, who took back the technique to their home countries, teaching orthopedists and rheumatologists alike. Rheumatologists described and analyzed the intra‐articular features of their common diseases in the ’60s and ’70s. A groundswell of interest from academic rheumatologists in adapting arthroscopy grew considerably in the ’90s with development of “needle scopes” that could be used in an office setting. Rheumatologists helped conduct the very trials the findings of which reduced demand for their arthroscopic services by questioning the efficacy of arthroscopic debridement in osteoarthritis (OA) and also developing biological compounds that greatly reduced the call for any resective intervention in inflammatory arthropathies. The arthroscope has proven an excellent tool for viewing and sampling synovium and continues to serve this purpose at several international research centers. While cartilage is now imaged mainly by magnetic resonance imaging, some OA features – such as a high prevalence of visible calcinosis – beg further arthroscopy‐directed investigation. A new generation of “needle scopes” with far superior optics awaits future investigators, should they develop interest.
