[20], Chudasama etal. 308 Ventura et al. 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. 4th ed. It's important to ensure that strength, stability and movement patterns are optimized before you return to an activity with a risk of ACL injury. Physiotherapy. Papers of special note have been highlighted as: of interest. It is postulated that intraosseous extension may be a finding more often associated with pain (8a).

It can be misdiagnosed a partial ACL tear. Accessed Nov. 13, 2018. Skeletal Radiol 2001 Jun; 30(6): 312-5. However, the presence of MD-ACL means the associated impingement symptoms have the propensity to continue despite the arthroplasty. 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. An anteriorly protruding ganglion (arrow) arising from an ACL ganglion cyst (arrowheads) is well seen on a proton density-weighted sagittal image.

Knee Surg & Relat Res 34, 40 (2022). The treatment alternatives, indications for the planned procedure and risks were discussed with her in detail and an informed consent was obtained. 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. Treatment is only required if there are otherwise unexplained symptoms. Quadriceps and hamstring weakness are common features of people with symptomatic degenerative meniscal tears Surgery may address the structural injury, but It also prevents excessive tibial medial and lateral rotation, as well as varus and valgus stresses [1]. They assessed the stability of the joint with the Lachman test intra-operatively, confirming it to be either grade zero or one, with firm end point, before commencing with the UKA [16]. .

They were however, supplemented by other objective methods such as comparison of pre-operative, post-operative and follow-up status of lateral view of plain radiograph in standing position, to look for any posterior translation of the femur which would suggest instability. The time it takes to recover is approximately 3 months. It can be misdiagnosed a partial ACL tear. These patients may complain of pain and stiffness, and large ganglia may cause limitation of extension.

Both groups showed overall improvement after surgery, however, patients who underwent debulking performed better at 2years follow-up in terms of Knee Society functional score, International Knee Documentation Committee scores, range of motion, rest pain and overall patient satisfaction (p<0.05) as compared with their counterparts.

Two characteristic MR appearances have been described for ganglion cysts of the ACL. 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 . A total of 488 patients diagnosed with MD-ACL (clinically and radiologically) underwent surgery during this period, of which 46 patients (9.43%) were lost to the minimum 2-year follow-up criteria or to matching of groups.
