A man with gonococcal urethritis who developed septic arthritis of both knees is described. The arthritis was complicated by rupture of bilateral synovial cysts. A rise in serum gonococcal complement-fixation antibody titer was demonstrated. Complement-fixing gonococcal antibodies with a high titer were observed in this synovial fluid. The patient responded well to antibiotic treatment and there was no permanent damage to his knee joints.

The role of the infrapatellar fat pad (IPFP) in knee osteoarthritis is not understood. This study aimed to identify relationships between MRI-based signal abnormalities in the IPFP and measures of structural pathology and symptom severity in PFJOA, as well as investigate the influence of obesity and sex on these relationships. Seventy participants (ages 28-80) with isolated PFJOA underwent bilateral knee MRI scan acquisitions and completed the Knee Injury and Osteoarthritis Outcome Score (KOOS).

This prospective pilot study examined the association between microorganisms and knee osteoarthritis by identifying pathogens in the synovial membrane, synovial fluid, and blood samples from two patients with primary bilateral knee osteoarthritis, using metagenomic next-generation sequencing (mNGS). Intraoperatively, during routine knee arthroplasty procedures, we collected the following 12 samples from each patient: two synovial membrane samples, two synovial fluid samples, and two venous blood samples. After DNA isolation and library construction, each sample was subjected to deep whole-genome sequencing using the DNBSEQT17 platform with the read length PE150 as the default.

Cervical synovial cysts, while uncommon, occur frequently at the C1/2 level. However, bilateral cysts at this level have not been previously reported. We report a 77-year-old man with cervicogenic headache caused by bilateral C1/2 synovial cysts.

Pigmented villonodular synovitis is a rare proliferative disorder of the synovial joints, characterized by synovial thickening and hemosiderin deposition. It predominantly affects the knee joint, with bilateral involvement being exceedingly rare. We present a case of diffuse bilateral pigmented villonodular synovitis in a 20-year-old female, initially presenting with left knee pain and swelling, diagnosed via MRI.
