2017-02-06 · Mucoid degeneration MD of the anterior cruciate ligament ACL is a rare pathological entity with disputed theories of origin. 1,2,3,4,5 It is characterized by infiltration of mucoid like substance glycosaminoglycans interspersed within the substance of ACL causing knee pain and limited motion. Purpose To determine whether anterior cruciate ligament ACL mucoid degeneration in participants with or at risk for osteoarthritis is associated with longitudinal risk of radiographic progression of medial tibiofemoral compartment joint space loss JSL.
Imaging criteria for mucoid degeneration included ill-defined ACL on T1-weighted and proton density-weighted images but with both bundles seen as intact on T2-weighted images, increased girth compared to normal, increased signal intensity on all sequences, normal orientation of the ligament, and celery-stalk appearance Fig. 1, Fig. 2. Mucoid degeneration of the ACL has been regarded as rare since its first imaging description 8, and even some of the more recent works about this subject still consider it an uncommon occur-rence 3–6, 9, with most articles based on case reports. However, a recent paper suggested that the. Multiple logistic regression was used to investigate the association between ACL mucoid degeneration at MR imaging and JSL progression at radiography, defined as a minimum joint space width decrease greater than 0.7 mm 48 months; cutoff according to mean and standard deviation of 1-year minimum joint space width changes in 90 knees of. 2016-12-10 · Mucoid degeneration of A C L is more common and literature has also reported many cases, but for PCL only few cases have been reported in English literature. We herein describe a case of PCL mucoid degeneration presented with secondary ACL impingement symptoms. 2012-05-17 · DISCUSSION. Mucoid degeneration of the ACL is a rare cause of knee pain. 1-8 This lesion of the ACL was first reported by Kumar et al. 3 in 1999. They reported that a biopsy indicated mucoid degeneration and a relief of symptoms could be.
For both anterior cruciate ligament ganglia and mucoid degeneration, both bundles of the ligament had to be seen as intact from origin to insertion to exclude partial tears. These imaging criteria for anterior cruciate ligament ganglion and mucoid degeneration were based on prior reports with MRI and histology correlation [6–9]. Mucoid degeneration of the ACL, along with tears and anterior cruciate ligament ganglion cysts, is a relatively common cause of increased signal within the ACL. Therefore, it is incumbent on radiologists to be familiar with the different surgeries performed for ACL reconstruction, the normal postoperative appearance, and complications that can be diagnosed with imaging. In this article, we present a comprehensive review of the imaging of ACL reconstruction and of its complications. The ACL is thickened and ill-defined with a "celery stalk" appearance. Its signal is increased on all sequences.
Mucoid degeneration of the anterior cruciate ligament MD-ACL is an underdiagnosed ACL pathology. When recognized, one potential management strategy involves arthroscopic debridement to “debulk” the ACL. Here, with the addition of video footage, we describe our arthroscopic technique for MD-ACL debridement using radiofrequency ablation. We. - age related senescent degeneration, - congenital or acquired synovial tissue entrapment between ACL fibers It is postulated that mucoid degeneration may be a predisposing factor to the formation of ACL ganglion cysts. On MRI the ligament is thickened, and ill-defined with a “celery stalk” appearance. Abstract Objective. To describe the MR features of mucoid degeneration of the anterior cruciate ligament ACL in a series of patients with MRI findings that were mistaken for tears in the majority of cases but who were found to have an intact ligament at arthroscopy.
Despite the association of mucoid degeneration of the cruciate ligaments and the long-standing reports about the MRI appearance of ACL mucoid degeneration, only a few studies in the radiology literature describe the MRI appearance of mucoid degeneration of the PCL [9, 10]. The tram-track PCL appearance commonly coexists with ACL mucoid degeneration; ganglia; and, less frequently, meniscal cysts. Both PCL tears and MRI findings suggestive of PCL mucoid degeneration show ligament thickening and increased PCL signal intensity. Tram-track PCLs are usually asymptomatic and typically have no ligamentous instability. OBJECTIVE. The purpose of our study was to describe the MR appearance and coexistence of anterior cruciate ligament ganglia with mucoid degeneration and to address the clinical significance of thes. Introduction: Mucoid degeneration of the anterior cruciate ligament ACL is a very rare cause of knee pain. Patient having mucoid degeneration of ACL seeks multiple orthopedic consultation and most of the time treating orthopedican miss its diagnosis either because of lack of experience or rare cause of pain unless doctor sought magnetic. 2016-09-29 · Surgery on mucoid ACL.

ACL mucoid degeneration is not an uncommon pathology, but is often unknown. According to Bergin et al. and Salvati et al., it should be present in 2 and 5%, respectively, of knee MRIs in current practice and most often affects men between 40 and 50 years old.
Anterior cruciate ligament mucoid degeneration is determined by interstitial glycosaminoglycan deposits amidst the collagen bundles causing ACL hypertrophy, knee pain, and limited range of motion. It is thought to arise from a primary synovial lesion and is associated with arthritic change or subsequent to acute or repeated trauma.

Mucoid degeneration of the anterior cruciate ligament ACL is not a well-known entity. Only 1 case of mucoid degeneration of the ACL has been reported in the English-language literature. This article describes 5 cases of mucoid degeneration of the ACL with clinical features, magnetic resonance imaging MRI findings, and a method of arthroscopic management of these cases. 2010-09-01 · MRI indicated a thickened ACL with increased signal on all sequences. Postoperatively, only six of 10 patients were confirmed by biopsy to have a mucoid degeneration of the ACL. An associated intraosseous tibial cyst or ganglion was observed only in patients with a definitive diagnosis of mucoid degeneration.
