Arthrofibrosis can occur after total knee replacement or partial knee replacement, when excessive scar tissue (collagen fibril) deposition occurs in and around the knee. This can be accompanied by shortening of the patellar tendon (patella baja/infera) which can also contribute to limited flexion.
After this, the patient can typically begin a more aggressive regimen of exercises involving stress on the knee, and increasing resistance. Jogging may be incorporated as well. After four months, more intense activities such as running are possible without risk. After five months, light ball work may commence as the ligament is nearly regenerated.
Articular cartilage does not usually regenerate (the process of repair by formation of the same type of tissue) after injury or disease leading to loss of tissue and formation of a defect. This fact was first described by William Hunter in 1743. [1] Several surgical techniques have been developed in the effort to repair articular cartilage defects.
Arthroscopic lavage is a "cleaning up" procedure of the knee joint. This short-term solution is not considered as an articular cartilage repair procedure but rather a palliative treatment to reduce pain, mechanical restriction and inflammation. Lavage focuses on removing degenerative articular cartilage flaps and fibrous tissue.
Anterior interval release (AIR) is a type of arthroscopic knee surgery performed to alleviate pain and associated symptoms caused by scar tissue (or fibrosis) accumulation in the anterior region of the knee, behind and under the knee cap (or patella), in a condition called arthrofibrosis.

The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol.
Scarring caused by acne (left), and photo one day after scar revision surgery: The area around sutures is still swollen from surgery. Scar revision is a process of cutting the scar tissue out. After the excision, the new wound is usually closed up to heal by primary intention, instead of secondary intention. Deeper cuts need a multilayered ...
