Knee Osteoarthritis after Arthroscopic Partial Meniscectomy: Prevalence and Progression of Radiographic Changes after 5 to 12 Years Compared with Contralateral Knee

J Knee Surg DOI: 10.1055/s-0038-1646926The purpose of this study was to study the clinical and radiographic changes in the knee after arthroscopic partial meniscectomy (APM) at a long-term follow-up compared with the contralateral knee. We assessed 57 patients (38 males and 19 females) with pre- and postoperative weight-bearing radiography with a follow-up ranging from 5.1 to 12.1 years (mean: 8.1) to analyze prevalence and progression of knee osteoarthritis (OA) after APM. We stratified patients according to body mass index (BMI), type of lesion (degenerative vs. traumatic), and side of meniscectomy (medial, lateral, and medial plus lateral). Patients were evaluated both clinically with Knee Osteoarthritis Outcome Score (KOOS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and radiographically with the Kellgren and Lawrence (K/L) score. Radiographic OA was defined as K/L grade 2 or worse. The prevalence of knee OA was 62.69% in the tibiofemoral compartment. The progression of knee OA was statistically significant, ranging from 17.2% preoperatively to 65.95% postoperatively (p = 0.001) in the medial compartment and from 17.64% preoperatively to 58.82% postoperatively (p = 0.0324) in the lateral compartment. The progression of knee OA in the patellofemoral compartment ranged from 5.26 to 42.10% (p = 0.001). The OA progression regarding BMI was higher into the obese group than the normal-weight group an...

ConclusionDespite minimal group-level effects of chronic diet-induced obesity and voluntary wheel running on knee OA pathology under the current test durations, diet and exercise substantially altered the relationships among systemic and local variables associated with early-stage knee OA. These results suggest that distinct pre-OA phenotypes may exist prior to the development of disease.Graphical Abstract

ConclusionThis study has evidenced that there is a large percentage of sub-threshold population. i.e. K-L grade 1 which is considered as border-line or doubt-full as far as OA diagnosis. Awareness of OA should be initiated at community level, which is needed for prevention of OA at early age.

CONCLUSIONS: Obesity-associated comorbidities most notably appeared to have a greater relative influence on cognitive performance than BMI itself in adults with severe obesity. This likely reflects the fact that a very elevated BMI was ubiquitous and thereby probably exerted a similar influence among all adults in the cohort. Accordingly, in the context of severe obesity, diabetes and other comorbidities may have greater sensitivity to cognitive deficits than BMI alone. PMID: 31116012 [PubMed - as supplied by publisher]

CONCLUSIONS: Of patients engaged in MOVE! in the VHA, 1.1% received WMM. WMM are underutilized among veterans. Additional research is needed to understand barriers to incorporating WMM into comprehensive obesity treatment plans. PMID: 31090207 [PubMed - as supplied by publisher]

There is a need to identify reliable biomarkers that can predict knee osteoarthritis (OA) progression. We investigated a panel of adipokines and some related inflammatory factors alone and their ratios for their associative value at assessing cartilage volume loss over time and symptoms in obese (High BMI) and non-obese (Low BMI) OA subjects.

Publication date: Available online 7 May 2019Source: Journal of OrthopaedicsAuthor(s): Subhadra Poornima, Krishna Subramanyam, Imran Ali Khan, Sumanlatha G, Qurratulain HasanAbstractIntroductionOsteoarthritis (OA) is a multifactorial disease with genetic factors playing a crucial role, and it has been associated with a family history of obesity. G595C polymorphism in the sterol regulatory element-binding protein 2 (SREBP2) gene has demonstrated an association with knee osteoarthritis (KOA) patients. However, this polymorphism has been never explored in an Indian population. Hence, the current study aimed to examine whether...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

Conclusions Two, Not Mutually Exclusive, Hypotheses We have reviewed and organized the literature with the intent of showing the existing parallels between excessive fat accumulation and the aging process. We have categorized these reports following what have been proposed to be the nine hallmarks of aging (21) (Figure 1). Based on the evidence, two distinct hypotheses can be proposed. One is that the cellular responses provoked by an excess of nutrients cause obesity, and that obesity is responsible for accelerating the pace of aging. Supporting this hypothesis are the observations that knocking out the fat-specific ins...
