Restorative Care

Restorative Care

Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Knee Joint

Knee Joint

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...

Growth of Cartilage and Bone Tissue

Growth of Cartilage and Bone Tissue

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...

Lewis Acids and Bases

Lewis Acids and Bases

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Weak Base Solutions

Weak Base Solutions

Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Ions as Acids and Bases

Ions as Acids and Bases

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

Area of Science:

Orthopedics and Sports Medicine
Regenerative Medicine
Biomaterials Science

Background:

Increasing incidence of articular cartilage injuries across all age groups.
Limited intrinsic healing capacity of articular cartilage due to poor vascularity and chondrocyte division.
Failure of conservative management necessitates reparative or reconstructive surgical options.

Purpose of the Study:

To review current treatment modalities for focal articular cartilage lesions.
To highlight the limitations of traditional cartilage repair methods (fibrocartilage).
To explore the potential of cell-based therapies for restoring hyaline cartilage.

Main Methods:

Review of current literature on cartilage repair and restoration techniques.
Analysis of lesion-specific and patient-specific variables influencing treatment selection.
Discussion of advances in cell-based strategies including mesenchymal stem cells, chondrocytes, and biomimetic scaffolds.

Main Results:

Nonsurgical management is effective for most focal cartilage lesions.
First-line surgical therapies often result in fibrocartilage repair with suboptimal biomechanical properties.
Cell-based approaches show promise for regenerating hyaline-like cartilage.

Conclusions:

Treatment selection for articular cartilage lesions is multifactorial.
Limitations exist with current repair methods, necessitating advanced techniques.
Cell-based cartilage restoration holds significant potential for addressing focal cartilage defects and restoring native hyaline cartilage.
