Summary
This summary is machine-generated.This study found significant gender differences in knee osteoarthritis cartilage loss patterns, particularly in the femur and tibia. These findings enhance understanding of knee osteoarthritis progression and may aid in evaluating new treatments.
Area Of Science
- Orthopedics
- Radiology
- Biomedical Engineering
Background
- Knee osteoarthritis (KOA) pathogenesis and progression exhibit gender-specific variations.
- Understanding these differences is crucial for developing targeted treatments and improving clinical trial design.
Purpose Of The Study
- To investigate gender differences in cartilage loss patterns within the central weight-bearing regions of the femur.
- To analyze cartilage volume changes over time using advanced segmentation techniques.
Main Methods
- Utilized the local area cartilage segmentation (LACS) method on 700 subjects with early to moderate knee osteoarthritis (Kellgren-Lawrence 1-3).
- Measured cartilage volume change in the indexed knee over four follow-up periods (24, 48, 72, and 96 months).
- Employed responsiveness heat maps to visualize cartilage loss patterns in sub-regions.
Main Results
- Statistically significant gender differences in cartilage loss were observed in the medial femur (MF), lateral femur (LF), and medial tibia.
- Heat maps revealed distinct patterns: posterior central weight-bearing LF loss and more generalized loss in the lateral tibia (LT) and MF.
- These patterns remained consistent across all four follow-up periods.
Conclusions
- The LACS method effectively identified gender-specific cartilage loss patterns in knee osteoarthritis.
- These findings provide valuable insights into the varied natural history of KOA between genders.
- The method shows potential utility in assessing the efficacy of interventions 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 upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
