Summary
Reduced femoral cartilage thickness (FCT) is linked to knee osteoarthritis (KO) in individuals with sarcopenia. Sarcopenia and FCT are significant predictors of KO, suggesting sarcopenia may be a risk factor for knee osteoarthritis.
Area of Science:
- Orthopedics
- Gerontology
- Radiology
Background:
- Sarcopenia, characterized by muscle mass and strength loss, is increasingly recognized as a factor influencing musculoskeletal health.
- Knee osteoarthritis (KO) is a prevalent degenerative joint disease, often associated with aging and biomechanical factors.
- The interplay between sarcopenia and knee joint structural integrity, particularly femoral cartilage thickness (FCT), requires further investigation.
Purpose of the Study:
- To evaluate the association between femoral cartilage thickness (FCT) and knee osteoarthritis (KO) in individuals with sarcopenia and pre-sarcopenia.
- To explore the role of FCT in the relationship between sarcopenia and KO.
- To identify predictors of KO and sarcopenia in an at-risk population.
Main Methods:
- A cross-sectional study involving 80 participants (aged 40-75 years) categorized into pre-sarcopenia, sarcopenia, and healthy control groups.
- Femoral cartilage thickness (FCT) was measured using ultrasound (US).
- Logistic regression and ROC analyses were employed to determine predictors of KO and sarcopenia, and to assess FCT's predictive capability for sarcopenia.
Main Results:
- Participants with sarcopenia exhibited significantly lower medial and lateral FCT compared to healthy controls (p < 0.01).
- Age and sarcopenia were identified as significant predictors of KO (p < 0.01).
- Knee osteoarthritis (KO) and reduced medial FCT were significant predictors of sarcopenia (p < 0.05), with medial FCT effectively predicting sarcopenia (AUC = 0.736).
Conclusions:
- Reduced FCT and increased KO prevalence were observed in individuals with sarcopenia.
- Sarcopenia is a significant predictor of KO, and decreased medial FCT is associated with sarcopenia.
- These findings suggest that sarcopenia may contribute to KO through mechanical effects related to muscle weakness, positioning sarcopenia as a potential risk factor for knee osteoarthritis.

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
