Joint cartilage formation induced by silastic sheet spacer
Scandinavian Journal of Plastic and Reconstructive Surgery
|January 1, 1982
Summary
This study found that a temporary silicone rubber sheet did not aid articular cartilage regeneration in rabbits. The induced cartilage degenerated, showing no benefit for treating degenerative arthritis.
Area of Science:
- Orthopedics
- Regenerative Medicine
- Biomaterials Science
Background:
- Articular cartilage damage is a significant clinical challenge.
- Current treatments for degenerative arthritis have limitations.
- Investigating novel methods for cartilage repair is crucial.
Purpose of the Study:
- To evaluate the efficacy of a temporary silicone rubber sheet in promoting articular cartilage regeneration.
- To analyze the long-term effects of subchondral bone coverage with a silicone sheet on cartilage repair.
- To determine if this method offers a beneficial treatment for degenerative arthritis.
Main Methods:
- Experimental study involving rabbits.
- Resection of normal articular cartilage from the medial condyle of the femur.
- Covering the subchondral bone with a 2 mm thick Silastic sheet for 2 months.
- Monitoring cartilage regeneration and degeneration after sheet removal.
Main Results:
- Initially, a hyaline-appearing cartilaginous tissue covered the resected surface after sheet removal.
- Within one month of removal, this cartilage exhibited significant degeneration.
- After a few months, no regenerating cartilage remained.
Conclusions:
- Temporary interposition of a silicone rubber sheet did not promote sustained articular cartilage regeneration.
- The study provides no experimental evidence to support this method as beneficial for degenerative arthritis treatment.
- Further research into effective cartilage repair strategies is warranted.

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...

01:29Bone Formation by Intramembranous Ossification
15.9K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:17Structural Joints: Cartilaginous Joints
4.9K
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...

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:24Bone Formation by Endochondral Ossification
14.2K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
