What is a Midsubstance rupture?
The more common ACL tear, however, is a midsubstance tear. This type of tear occurs primarily as the ligament is transected by the pivoting lateral femoral condyle.
What causes mucoid degeneration of ACL?
The pathogenesis of mucoid degeneration is unclear, but injury, ganglion cysts, and degenerative process have been implicated as the most likely etiologic factors in the production of this change.
What is mucoid degeneration?
Mucoid degeneration (MD) is a rare pathological affection of the anterior cruciate ligament (ACL). Mucinous material within the substance of ACL produces pain and limited motion in the knee.
What is ACL ganglion cyst?
Anterior cruciate ligament (ACL) ganglion cyst and ACL mucoid degeneration are two non-traumatic pathologies that have been increasingly found be associated with insidious onset chronic knee pain. They may also present as a limited range of motion of the knee due to either pain or mechanical block [1-4].
What is the difference between an ACL rupture and tear?
Is it a Rupture or a Tear? Getting straight to the point: A rupture and a tear are the same thing. When a person suffers from a cut to either a muscle or ligament, they have either ruptured or torn the injured body part. This type of injury is the result of a sudden body movement.
Does mucoid degeneration of ACL require surgery?
Treatment for MDACL usually starts non-surgically with anti-inflammatory drugs and physiotherapy. Surgical treatment involves arthroscopic debridement of ACL, with partial or total resection, occasionally combined with ACL reconstruction.
What is the treatment for mucoid degeneration of ACL?
Treatment of ACL mucoid degeneration by arthroscopic resection is effective for posterior pain and flexion limitation. It results in postoperative laxity, but rarely in frank instability. Therefore, indications for ACL resection must be carefully selected.
What is mucoid degeneration of the meniscus?
We believe that meniscal mucoid degeneration with tear is not uncommon. Accumulation of mucopolysaccharides at the meniscal interstitial area disrupts the collagen network and weakens the meniscus. Such meniscal tears are not appropriate for repair most of the time (Fig. 2).
How do you fix mucoid degeneration?
Our study provides further evidence that arthroscopic total or partial excision of anterior cruciate ligament is a safe and effective treatment for mucoid degeneration of the anterior cruciate ligament, improving patient satisfaction and function without causing clinical instability in daily activities.
What causes ACL cyst?
Since the ACL is an extrasynovial structure, irritation or trauma to the synovium covering the ACL may initiate the release of hyaluronic acid and the production of mucin causing the development of a ganglion cyst within or adjacent to the cruciate ligament [6].
How do you treat an ACL cyst?
Currently, arthroscopic resection of the cyst is the most common method of treatment for symptomatic cysts. Arthroscopic debridement for this condition could lead to complications, such as iatrogenic injury to the ACL.
Is a ruptured ACL a complete tear?
An ACL injury may be diagnosed when the ligament is overstretched or torn. The tear may be partial or complete; a complete tear of the ACL is also known as an ACL rupture.
What is worse a tear or a rupture?
What is the difference between a degenerative and a traumatic meniscus tear?
Traumatic meniscus tears overall exhibited higher inflammatory/catabolic response as evidenced by higher levels of chemokines and matrix metalloproteinases expression than degenerative tears. These findings suggest that there is a (molecular) biological distinction between traumatic and degenerative tears.
What causes degenerative meniscus tears?
What are the Causes of Degenerative Meniscal Tears? There is no one specific cause of degenerative meniscal tears. They are probably an early sign of osteoarthritis (the normal aging process of joints), rather than a completely separate diagnosis.
