ACL Graft Tear - Radsource It can be secondary to trauma, or simply degeneration caused by meniscal injury, osteoarthritis or chondral damage [2]. Accumulation of mucopolysaccharides at the meniscal interstitial area disrupts the collagen network and weakens the meniscus. (PDF) Mucoid Degeneration of the Anterior Cruciate Ligament : A Case Both the patient groups were matched for age, gender, pre-operative ROM and functional scores, minimising any confounding effect in data collection. He did total knee replacement on both side and now my mother is walking without aid. When a cruciate ligament ganglion is discovered incidentally, no intervention is necessary. Part of fatty degeneration deposit of fat globules in a tissue. Inclusion criteria was as follows: (1) clinicoradiological confirmation of MD-ACL and medial compartment osteoarthritis (MCOA) of the affected knee joint; (2) patients with less than 10 of varus or 5 of valgus deformity and (3) patients with no flexion contracture. While both the groups showed improvements in the functional scores post-surgery, which could be attributed to the UKA primarily, the finding that patients in whom debulking was done had better mean IKDC and mean KSS at 2years follow-up confirmed the study hypothesis that debulking improves the long-term outcome in patients with MD-ACL undergoing UKA. Others may make an appointment with their family doctors.

Signal intensity of the anteromedial bundle (AMB) or posterolateral bundle (PLB) graft standardized to the intensity of the PCL was defined as signal intensity ratio (SIR). Grade 1A laxity on Lachmans test (less than 5mm translation with a firm end-point) was noted in 27 knees (11.95%) intra-operatively in group B or those who underwent debulking (nb=226), whereas a firm endpoint with no translation was noted in all of the remaining 199 knees (88.05%).

Proton density-weighted sagittal demonstrates a diffusely increased size of the ACL with ill-defined increased signal and interspersed intact ACL fibers. Mucoid degeneration of ACL is a disease affecting ACL in which mucoid like substance (glycosaminoglycans) gets interspersed within the substance of ACL and as a result ACL gets thickened.

Sterile saline (salt) solution is pumped into the knee through one incision to expand it and to wash blood from the area. Introduction: Mucoid degeneration of the anterior cruciate ligament (ACL) is commonly treated with arthroscopic debridement of the ACL. With an increasing trend of UKA being performed worldwide, the role of addressing concomitant MD-ACL is vital in improving the overall outcome of the patient without causing any instability or implant failure, as shown in this study. I have persistent pain in the back of that knee that is exacerbated by walking and bending it. 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. Do you ever feel that your knee is unstable or unable to support your weight? Follow the R.I.C.E.

Only mobile-bearing UKA design was used in all the patients; hence the findings may differ in patients undergoing UKA with different implant designs such as fixed-bearing UKAs. Although asymptomatic in most cases, MD-ACL has been associated with posterior knee pain and restriction of terminal flexion or extension, in addition to pain and discomfort after sitting for a prolonged period of time [4, 5]. 10, No. Usually there is no history of any significant trauma. .

Often the diagnosis can be made on the basis of the physical exam alone, but you may need tests to rule out other causes and to determine the severity of the injury. Pre-operative and follow-up lateral radiographs of the patients who underwent debulking were analysed by a blinded radiologist and no posterior translation of the femur was noted, thereby confirming no instability caused by the debulking (Fig. (8a) Intraosseous extension of an ACL ganglion. Indian J Orthop 48(2):197202. As previously reported, typical symptoms of mucoid degeneration of the ACL include knee pain during deep flexion and painful limitation of motion. Therefore, indications for ACL resection must be carefully selected. Score: 4.7/5 (45 votes) . Am J Roentgenol 182(5):12831287.
