“…Three studies reported associations between trochlear dysplasia with mucoid degeneration of the ACL or TT–TG and mucoid degeneration of the ACL [2, 14, 33] (Table 5). One study comprising 133 patients found a significant positive correlation between TT–TG and mucoid degeneration of the ACL ( p < 0.02) but not with trochlear dysplasia [2], with another study also reporting a significant positive correlation between TT–TG and mucoid degeneration of the ACL ( p <0.05) in addition to a significant correlation between trochlear dysplasia type and mucoid degeneration of the ACL ( p = 0.016) [33].…”

“…Diagnosis of mucoid degeneration of the ACL was performed through a combination of MRI, arthroscopy and histology. Diagnosis of mucoid degeneration of the ACL was supported by MRI findings of a thickened ACL with increased signal intensity or mucoid hypertrophy of the ACL with “celery stalk” appearance [2, 13, 14, 33, 35]. Arthroscopic findings suggestive of mucoid degeneration of the ACL included a hypertrophic, bulbous, yellowish gross appearance [6, 13, 14, 34].…”

“…Several studies have investigated the association between mucoid degeneration of the ACL and certain anatomical measurements on radiographs and MRI. These include posterior tibial slope, notch width index, transverse notch angle, tibial tubercle to trochlear groove (TT–TG) distance, and trochlear dysplasia [2, 14]. Due to the increasing number of studies on this topic within the past few years, this systematic review aims to outline the current evidence on morphological features that are associated with mucoid degeneration of the ACL.…”

PurposeTo determine what knee morphological factors are associated with the development of mucoid degeneration of the anterior cruciate ligament (ACL). Methods Three databases MEDLINE, PubMed and EMBASE were searched from inception to January 29th, 2023 for literature outlining knee morphological factors that potentially lead to the development of mucoid degeneration of the ACL. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data on receiver operating characteristic (ROC) curve parameters such as area under the curve (AUC), sensitivity and speciicity, odds ratios, as well as p values for comparisons of values between mucoid degeneration of the ACL and control patients were recorded. The Methodological Index for Non-Randomized Studies (MINORS) score was used for all studies to perform a quality assessment of included studies. Results A total of 7 studies comprising 1326 patients (1330 knees) were included in this review. Four studies reported a signiicant association between increasing posterior tibial slope angles and mucoid degeneration of the ACL presence, with one study specifying that posterolateral tibial slope had a greater association than posteromedial tibial slope. Two studies reported a signiicant association between lower notch width index values and mucoid degeneration of the ACL presence. One study found that the presence of trochlear dysplasia was correlated with mucoid degeneration of the ACL and two studies found that increased tibial tuberosity-trochlear groove distance (TT-TG) was associated with mucoid degeneration of the ACL. Conclusion Increased posterior tibial slope, decreased notch width index, and elevated TT-TG and trochlear dysplasia were associated with the presence of mucoid degeneration of the ACL. Information from this review can aid surgeons in understanding what morphological features predispose their patients to the development of mucoid degeneration of the ACL. Identifying what features predispose patients to mucoid degeneration of the ACL can help determine if regular screening or preventative strategies are necessary. Level of evidence Level III.

“…The average percentage of included females was 26.4%. One study used platelet-rich plasma (PRP) with circumferentially shaving of the ACL with a shaver until the ligament was the size of a native ACL [2]. Another study performed the same procedure but without PRP and with an RFA probe [25].…”

Purpose To determine clinical outcomes and risks of various management strategies for mucoid degeneration of the anterior cruciate ligament (MD-ACL). Methods Three databases MEDLINE, PubMed and EMBASE were searched from inception to January 29th, 2023 for literature outlining clinical outcomes for various management strategies of MD-ACL. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data on satisfaction scores, visual analogue scale (VAS) scores, Lysholm scores, International Knee Documentation Committee (IKDC) scores, Knee Osteoarthritis and Outcome Scores (KOOS), range of motion and Lachman test were recorded. Results A total of 14 studies comprising 776 patients (782 knees) were included in this review. Partial debridement was reported in ten (71.4%) studies comprising 446 patients, showing signiicant improvements in VAS, Lysholm, IKDC scores and range of motion. Complete debridement was reported by two (14.2%) studies comprising 250 patients, and resulted in increases in Lysholm scores, KOOS, and range of motion. Reduction plasty was reported in two (14.2%) studies comprising 26 patients and showed improvements in VAS and Lysholm scores, and range of motion. Other methods of treatment included conservative management and ultrasound decompression. Complete debridement resulted in 10/23 (43%) patients with a positive Lachman test. This was followed by reduction plasty and partial debridement, with 5/26 (19.2%) and 45/340 (13.2%) patients respectively having positive Lachman or elevated knee arthrometer scores. Pivot shifting was only reported in studies on partial debridement and reduction plasty, with 14/93 (15.1%) and 1/21 (4.8%) patients have positive results, respectively. Conclusion The most commonly reported management strategy for MD-ACL is partial debridement with complete debridement, reduction plasty and conservative management as alternative options. Current operative management strategies place individuals at risk for ACL insuiciency. Information from this review can aid surgeons and clinicians in understanding what treatment options are best for this patient population, by understanding the reported clinical beneits and risks of each strategy. Level of evidence IV.
