Ever since mucoid degeneration of the anterior cruciate ligament (MD-ACL) was named by Kumar etal. . To summarize, debulking of mucoid ACL in patients undergoing unicompartmental knee arthroplasty significantly reduces the rest pain and improves the final range of motion of the knee joint, subsequently improving the overall functional and clinical outcome of the patient and resulting in greater patient satisfaction. Discrete intraosseous ganglia are observed in 3/4 of the cases with mucoid degeneration of the ACL. : any of various mucoproteins that occur especially in secretions of mucous membranes. Medical Definition of mucoid degeneration. It is postulated that mucoid degeneration may be a predisposing factor to the formation of ACL ganglion cysts . All 5 patients under- went arthroscopic surgery. Score: 4.7/5 (45 votes) . cystic degeneration degeneration with formation of cysts. However, in some patients, ACL ganglion cysts cause significant clinical symptoms. It is postulated that intraosseous extension may be a finding more often associated with pain (8a). After a database search of 4,221 knee MRI examinations, Bergin et al. Mucoid degeneration of the anterior cruciate ligament (ACL) is a common pathology but is often unknown and underdiagnosed. Indian J Orthop 48(2):197202. The follow-up period was similar to that of Cha etal.

For such patients, decompression of the ganglion at arthroscopy or via CT guidance is indicated and provides prompt relief.3,5,6. Surgery is typically not needed. https://doi.org/10.1016/j.knee.2010.05.003, Keyes GW, Carr AJ, Miller RK, Goodfellow JW (1992) The radiographic classification of medial gonarthrosis. UKA by itself improves the functional and clinical outcome of patients with medial compartment osteoarthritis. However, in the case of mucoid degeneration . I get PT and acupuncture, have had several epidural injections, and am trying hard to avoid osteoporosis meds (was on bisphosphonates for many years many years ago) as well as spinal fusion. Methodology: Five patients who were diagnosed as a case of mucoid degeneration of the ACL based on MRI, over a period of 1 year (December 20182019), were included in the study. Questions just answered: mucoid degeneration of acl physiotherapy. During the physical exam, your doctor will check your knee for swelling and tenderness comparing your injured knee to your uninjured knee. Wilcoxon signed rank test was used for longitudinal intra-group comparison of ROM and PROMs between pre-operative and follow-up scores, whereas Mann Whitney U test was used to compare ROM and PROMs between the two groups at 2years follow-up. Methods From January 2012 to August 2013, 32 knees (24 females and 8 males with left knee of 14 and 18 of right) were diagnosed with mucoid degeneration of the ACL and underwent arthroscopic treatment, all of whom with a mean age of 58.817.97 years (42-74 years). J Orthop Traumatol. . Treatment is only required if there are otherwise unexplained symptoms. https://www.uptodate.com/contents/search. The appearance can mimic acute or chronic interstitial partial tears of the ACL. On exposure of the joint, ACL was looked for in terms of integrity and any degenerative changes. [6] and Lintz etal. Despite recent developments suggesting that debulking of MD-ACL does not cause instability [8], the involvement of another surgery that can directly be impacted by it complicates the decision making. Diagnosis is usually made on the MRI. [2]. [5] and Chudasama etal. When the arthroscopy hook was attempted to be passed between the lateral femoral condyle and the lateral aspect of the ACL, it was noticed that the impinging fibers of the mucoid ACL blocked its passage, thereby not allowing the hook to be passed between the lateral femoral condyle and the lateral aspect of the ACL, which is otherwise possible in cases with normal ACL. what causes mucoid degeneration of acl. https://doi.org/10.1302/0301-620X.73B4.2071640, Pandit H, Gulati A, Jenkins C (2011) Unicompartmental knee replacement for patients with partial thickness cartilage loss in the affected compartment. https://doi.org/10.20546/ijcrar.2016.411.003, Chudasama CH, Chudasama VC, Prabhakar MM (2021) Arthroscopic management of mucoid degeneration of anterior cruciate ligament.

Int J Sports Phys Ther 10(1):5261, PubMed 4 McIntyre J, Moelleken S, Tirman P: Mucoid degeneration of the anterior cruciate ligament mistaken for ligamentous tears . The minimum follow-up was 3 years. It can be secondary to trauma, or simply degeneration caused by meniscal injury, osteoarthritis or chondral damage [2]. . Shelbourne Knee Center recommends activity modification and rest, medications, injections and/or physical therapy as the initial treatment(s). Patients will . Some patient may also complain of pain with full knee extension. The purpose of this study was to investigate the outcomes of management of mucoid degeneration of the anterior cruciate ligament (MDACL) by performing a systematic review of methods of treatment that have been reported. The anterior cruciate ligament (ACL) is an important ligament in the knee. As this improvement might not be entirely due to PRP, high-end comparative studies are needed to confirm its efficacy. Sagittal T1-weighted (1a) and fat-suppressed proton density-weighted (1b) images. It is commonly associated with characteristic clinical findings such as progressive knee pain and discomfort on prolonged sitting or standing in a fixed posture, without history of a significant trauma or instability preceding the symptoms. Methodology: Five patients who were diagnosed as a case . Patients with mucoid ACL undergoing mobile-bearing UKA at five different centres by five different arthroplasty surgeons were included. As we age, the connections between the collagen fibers that make up the meniscus begin to deteriorate, causing failure of the structure and tears due to stresses in the joint. Secondly, all the patients underwent the surgery and postoperative rehabilitation based on a standardized protocol which may limit the reproducibility of results if not adhered to. They are frequently seen at joints and tendons of the wrist but are rare in the region of knee joint. On inter-group comparison, VAS score for rest pain of the debulking group (0.130.46) was also found to be lower than the non-debulking group (2.640.95) (p<0.05). 18 Apr 2021. But many studies have reported the weakening and laxity of ACL postoperatively and on follow-up. Such meniscal tears are not appropriate for repair most of the time (Fig. Investigation, data curation, validation, writing original draft was done by U.S., A.M., S.G. and R.G. . If nothing is done, the ACL injury may turn into chronic ACL deficiency. Autologous PRP, prepared by double spin protocol, was injected into the remaining ACL after partial debridement was done. https://doi.org/10.1302/0301-620X.93B4.25562, Mittal A, Meshram P, Kim WH, Kim TK (2020) Unicompartmental knee arthroplasty, an enigma, and the ten enigmas of medial UKA. On physical exam, the Lachman test for ACL instability is negative with an ACL ganglion. As per study population statistics, the prevalence of medial meniscus tears (29.64%) in this study were congruent to the rates found in studies by Srivastava etal. https://doi.org/10.1016/j.eats.2017.11.006, Srivastava A, Pateliya S, Singh H, Aggarwal S, Srivastava S (2016) Mucoid degeneration of anterior cruciate ligamentmanagement and functional outcome of 18 cases. Knee Surg Sports Traumatol Arthrosc 19(8):13261333. Anterior and posterior cruciate ligament ganglion cysts are reported in the literature as being rare with an incidence of approximately 0.5% to 1%.1,2 However, in our experience, this entity is encountered more commonly, most often within the anterior cruciate ligament. A total of 442 patients (na=216; nb=226) fulfilled the inclusion criteria and were followed up until a minimum of 2years post-surgery (mean: 252.46months; range: 2427.5months). 2001. However, upon following-up with these patients, and gauging their clinical and functional parameters, complaints of rest pain and restriction of terminal flexion seemed to persist. Subsequently, the final sample included 442 patients who were followed-up for at least 2years after surgery (Fig. I remember that Dr. Jain came out from his clinic to see my mother because my mother was not able walk a single step. Correlations between degree of knee instability and SIR were assessed for each bundle, each time point, and each sequence. 3, 2018 www.ecios.org Mucoid degeneration (MD . Google Scholar, Cha JR, Lee CC, Cho SD, Youm YS, Jung KH (2013) Symptomatic mucoid degeneration of the anterior cruciate ligament. This denoted adequate release of the impinging fibers against the lateral femoral condyle, femoral notch and PCL. The power of the study for the corrected model was estimated to be 92% for the aforementioned sample size when keeping the value of as 0.05, the degree of freedom (df) as 1, and adjusted R2 as 0.023. 4 McIntyre J, Moelleken S, Tirman P: Mucoid degeneration of the anterior cruciate ligament mistaken for ligamentous tears. Reactive marrow edema (arrowheads) surrounds the intraosseous ganglia. The ligament can also tear due to work injuries or automobile accidents. Paterno MV, et al. Privacy PubMed Although a few studies such as the one by Lee etal. During arthroscopic ACL reconstruction, the surgeon makes several small incisionsusually two or threearound the knee. The soft-tissue thickening and increased signal intensity along the course of the ligament with either form of cyst may be confused with the appearance of an ACL tear. [20], Chudasama etal. Informed written consent was obtained from all patients. A: ACL (anterior cruciate ligament) mucoid degeneration means the lesion of the ACL. This allows the doctor to see the knee structures more clearly. Quadriceps and hamstring weakness are common features of people with symptomatic degenerative meniscal tears Surgery may address the structural injury, but Freedom from war and natural disaster. b Open debulking of mucoid ACL under direct vision using 15-number blade. These are found inside your knee joint. Treatment options include non-operative management, arthroscopic debridement with a biceps tenotomy or tenodesis, complete or partial repair, patch augmentation, superior capsular reconstruction, muscle/tendon transfer and reverse total shoulder arthroplasty. . 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. Intraosseous increased signal is present within the tibial spine deep to the posterior extent of the ACL insertion (arrowhead). Mayo Clinic is a not-for-profit organization. Not really known: Mucoid degeneration of the ACL is seen most commonly in adults (35-55 years of age). Anterior cruciate ganglion cysts are probably more prevalent than stated in the literature. Dietary management and various treatments Scanning and diagnostic . After surgery patient is allowed to walk from the next day. Accumulation of mucopolysaccharides at the meniscal interstitial area disrupts the collagen network and weakens the meniscus. 2). Voxel numbers of . Despite integrity and status of cruciates being paramount in a UKA, no study has evaluated the effect of debulking MD-ACL in this procedure. You can read more if you want. Common wrist ganglions include: dorsal wrist ganglion volar wrist ganglion volar retinaculum ganglion extensor retinaculum ganglion occult ganglion intraosseous ganglion mucous cyst In a 2007 study of patients in Glasgow whose foot lumps were removed surgically, 39 of 101 cases were ganglion cysts. Functional assessment was done by the same clinician using patient-related outcome measures (PROMs) using the self-questionnaire-based International Knee Documentation Committee (IKDC) score, Knee Society score (KSS), VAS score (for rest pain) and subjective satisfaction level. Philadelphia, Pa.: Saunders Elsevier; 2015. https://www.clinicalkey.com. fibroid degeneration degeneration of a leiomyoma with subsequent fibrosis. https://doi.org/10.1016/j.knee.2020.06.004, Article Being a multicentric study involving five different surgeons, surgeon factors could potentially affect surgical procedure and clinical outcome, despite a predetermined endpoint for the debulking. Another theory states that it is a consequence of herniation of a synovial pouch in the substance of the anterior cruciate ligament (ACL), and the subsequent synovial filling inside it; however, the major aetiology of MD-ACL still remains an enigma [4]. The most common cause of meniscus tears is age related degeneration. Modalities such as icing, joint mobilization, and massage can provide short-term pain relief and reduce swelling. Others may make an appointment with their family doctors. [] found the incidence of mucoid degeneration in their study population to be 1.0%.Most of their reported cases were incidental findings without contributory symptoms.
