The scores were then compiled and statistically analysed using SPSS-24 software to understand if the debulking resulted in any significant difference in the outcomes. Mucoid degeneration of the anterior cruciate ligament (ACL) is a common pathology but is often unknown and underdiagnosed. 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.

[20], Chudasama etal. Methodology: Five patients who were diagnosed as a case . Hence, the improvement in ROM, attenuation of rest pain and better long term functional outcome measures supported the hypothesis regarding the positive effect of debulking a MD-ACL in patients undergoing UKA.

Informed written consent was obtained from all individual participants included in the study. Its function is to stabilize the knee while bending and rotating; the ACL also keeps the knee from shifting out of place or moving anteriorly (toward the front) with pivoting activities. Your knee may become more and more unstable and may give out more often. 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. An ACL sprain is when the ACL is overstretched (but not torn). the degree of laxity, and the patient's age and willingness to pursue vigorous postoperative physical therapy are other major determinants. The purpose of this study was to diagnose mucoid degeneration of anterior cruciate ligament and to assess the effectiveness of arthroscopic treatment in these patients.Materials and MethodsBetween December 2007 and November 2011, 20 patients were diagnosed to be suffering from mucoid degeneration of anterior cruciate ligament (ACL) on the basis .

Plain radiographs were taken in anteroposterior and lateral views at 2years follow-up for radiological analysis in the form of implant failure in all patients or anterior tibial translation in group B by a blinded radiologist. Once considered a rare disease, it is probably a less diagnosed condition of knee pain. These cysts have a variable MR appearance and are not always confined to the substance of the ligament. 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. Sagittal T1-weighted (1a) and fat-suppressed proton density-weighted (1b) images. There was a statistically significant improvement in the mean IKDC and mean KSS of both the groups at 2years of follow-up as compared with their pre-operative scores (p<0.05).

Unicompartmental knee arthroplasty (UKA) has rapidly emerged as a superior surgical option to total knee arthroplasty for bone-on-bone osteoarthritis owing to less trauma to the surrounding soft tissue, more conservative bone cuts, minimal bleeding, smaller incision, a better range of motion (ROM), faster recovery, preserved kinematics, higher rate of implant survival and decreased chances of major complications such as thromboembolism, cardiac arrest and stroke [9]. 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. On exposure of the joint, ACL was looked for in terms of integrity and any degenerative changes. Accumulation of mucopolysaccharides at the meniscal interstitial area disrupts the collagen network and weakens the meniscus. During arthroscopic ACL reconstruction, the surgeon makes several small incisionsusually two or threearound the knee.

Treatment is only required if there are otherwise unexplained symptoms. 1). Instrumental treatment. Modalities such as icing, joint mobilization, and massage can provide short-term pain relief and reduce swelling. The anterior cruciate ligament (ACL) is a key structure in the knee joint kinematics, as it resists anterior tibial translation and rotational loads. An anteriorly protruding ganglion (arrow) arising from an ACL ganglion cyst (arrowheads) is well seen on a proton density-weighted sagittal image. On longitudinal, intra-group comparison of the individual groups, it was noted that there was statistically significant (p<0.05) improvement in the ROM of patients who underwent debulking (Z-value: 13.047; p-value: 0.00) as well as no debulking group (Z-value: 9.990; p-value: 0.00) at 2years follow-up, compared with their individual pre-operative ROM. Finally, the patients who underwent debulking had a better mean subjective patient satisfaction (9.830.37 versus 8.680.71) at the final follow-up at 2years (p<0.05) (Table 2). Investigation, data curation, validation, writing original draft was done by U.S., A.M., S.G. and R.G.
