Risk factors for progression of radiographic knee osteoarthritis in elderly community residents in Korea

Knee osteoarthritis (OA) is the most common form of arthritis affecting the elderly. Understanding the risk factors for knee OA has been derived from cross sectional studies. There have been few longitudinal s...

n E Abstract The role of the patella is paramount in the transmission of the quadriceps muscle forces, the increase of the lever arm, the distribution of the forces on the trochlea and the centring of the extensor apparatus. Despite the low incidence of patellar factures in comparison with other lower limb fractures, the painful and functional complications, such as knee stiffness, loss of extension and patellofemoral osteoarthritis, can be very disabling and will often compromise the return to a professional or recreational activity and induce falls in the elderly population. Treatment can be conservative or surg...

The objective of this study was to determine whether dietary patterns, derived by principal components analysis (PCA), are associated with KOA progression. METHODS: In the Osteoarthritis Initiative (OAI), a prospective cohort with clinical centers in Maryland, Ohio, Pennsylvania, and Rhode Island, 2757 participants with existing KOA (mean age 62 y) and diet assessed at baseline were followed for ≤72 mo. Using PCA, Western and prudent dietary patterns were derived. Radiographic KOA progression was assessed using 2 separate measures, 1 full Kellgren-Lawrence (KL) grade increase and loss in joint space width (JSW). Sy...

ConclusionsGreater severity of structural and inflammatory hand OA pathologies was associated with lower pressure pain thresholds at finger joints, indicating pain sensitization. Our results indicate that pain sensitization might be driven by structural and inflammatory pathology in hand OA.

ConclusionIn contrast to the widespread belief that most lateral OA patients have valgus knee alignment, a substantial proportion of Korean patients with severe lateral OA in this study had non-valgus alignment. In addition, these non-valgus alignment patients presented with significantly milder clinical manifestations in bone-on-bone lateral OA than valgus patients. While orthopaedic surgeons tend to initially consider surgery for bone-on-bone lateral OA, full-limb radiographs should be acquired to assess knee alignment, because patients with non-valgus alignment may be treated conservatively.Level of EvidenceIII, Case control study.

Authors: Üstün I, Solmaz A, Gülçiçek OB, Kara S, Albayrak R Abstract OBJECTIVES: Bariatric surgery is an effective intervention for severe obesity and associated comorbidities. We compared symptoms, joint space and life quality of morbidly obese patients with symptomatic knee osteoarthritis before and after bariatric surgery. METHODS: 34 patients with knee osteoarthritis were evaluated with standing anteroposterior and lateral radiography, medial and lateral joint distances of the knees, Visual Analog Scale (VAS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) que...

ConclusionIn patients with symptomatic KOA, the presence of knee CC did not affect the risk of arthroplasty or disease progression at 5 years.

This study comprised of 12 patients whose knees were evaluated with standard radiographs and MRI to identify and localize the bone marrow lesions. They then underwent subchondroplasty under intraoperative radiographic guidance. Preoperative and postoperative visual analog scale (VAS) pain scores, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and Knee Injury and Arthritis Outcome Scores (KOOS) were obtained. VAS scores improved significantly from 7.5 ± 1.8 before surgery to 5.2 ± 2.7 after surgery. This further improved to 2.1 ± ...

ConclusionStemless shoulder implants can provide significant improvement in functional scores in RA patients in the short term. However, early bone loss around the humeral implant is a concern and the authors recommend long-term clinical and radiological follow-up.

Rationale: Hereditary multiple exostoses (HME) is an autosomal dominant disease that causes multiple exostoses throughout the body. It usually occurs around the metaphysis of the long bones, and when it involves the hip, symptoms arise due to deformity and the mass effect. If the lesion does not involve the joint or is not associated with arthritis, symptoms can be relieved by surgical excision of the osteochondroma. However, if secondary osteoarthritis (OA) or subluxation of the joint has progressed, joint replacement arthroplasty should be considered. Patient concerns: A 57-year-old woman with HME visited our outpat...

Authors: Pincus T, Castrejon I, Yazici Y, Gibson KA, Bergman MJ, Block JA Abstract Osteoarthritis (OA) may be associated with substantial work disability, morbidity, costs, and increased mortality rates, often similar to rheumatoid arthritis (RA), documented in many published reports over the last 4 decades. However, OA generally has been viewed as less severe than RA. This discrepancy may be explained in part by:a) RA may have been considerably more severe in the past, prior to effective therapies.b) most older individuals have radiographic joint damage, which often is not associated with clinical symptoms.c) RA i...
