“…63 Complications after meniscus allograft transplantation occur in $20% of cases and include allograph extrusion and/or shrinkage, progressive high-grade chondrosis, arthrofibrosis, and synovitis. 56,64 An association between increased signal intensity of the graft and graft rejection has not been found. 65…”

“…In contrast, if the meniscectomy involves resection of more than the 25% of the meniscus, the diagnostic performance of conventional MRI significantly decreases. 56 Signs indicative of a recurrent meniscal tear after meniscectomy include fluid-like signal intensity cleft within the meniscus on T2-weighted images or a displaced meniscal flap (►Fig. 15).…”

“…Some of the MRI findings, which may be visible during the first postoperative year include: progressive increased intrameniscal signal intensity, decreased width and increased thickness of the meniscal body, and meniscal extrusion. 56 The transplanted lateral meniscus extrudes more significantly than the medial, and it has been shown that if the meniscus does not extrude in the early postoperative period, it is unlikely to extrude within the first postoperative year. The clinical implication of the presence of meniscal extrusion is not clear with wide variation of results in the literature.…”

Diagnosing Meniscal Pathology and Understanding How to Evaluate a Postoperative Meniscus Based on the Operative Procedure

Magnetic resonance imaging (MRI) represents the preferred noninvasive imaging technique to diagnose meniscal pathology in the pre- and postoperative setting. Furthermore, characterization of meniscal tissue MR properties has been possible by the development of advanced MRI techniques. Suspected meniscal tears are a frequent indication for MRI and the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification system has been developed to facilitate accurate and uniform reporting of such meniscal tears. Partial meniscectomy and meniscal suture repair are among the commonly performed procedures and several signs have been described to detect postoperative recurrent tears on MRI. Other techniques that have proven useful for meniscal assessment are ultrasound (US) and computed tomography (CT) arthrography. In recent years, US is being increasingly used in the selective assessment of some meniscal pathology such as tears, parameniscal cysts and meniscal extrusion as it is a relatively inexpensive, accessible, and safe technique. CT arthrography has been advocated as an acceptable alternative in patients with contraindications for MRI, with comparable diagnostic performance.

“…However, this approach may not be appropriate for some practices, as it is more time‐consuming and difficult to schedule. Other groups will either perform arthrography in all patients with prior meniscus surgery, or perform conventional MRI in all cases and reserve arthrography only for problematic cases …”

“…eniscal tears are among the most common types of structural knee injury (1), which can either occur after an episode of knee trauma during sports or in older individuals as a degenerative process without a traumatic onset (2). Overall, there is an increasing trend in the incidence of meniscal tears, which can potentially jeopardize the future function and force absorption of the affected knee (2,3).…”

Meniscal Surgery: Risk of Radiographic Joint Space Narrowing Progression and Subsequent Knee Replacement—Data from the Osteoarthritis Initiative

et al. 2017

View full text Add to dashboard Cite

Purpose To investigate the risk of radiographic joint space narrowing (JSN) progression evaluated in subjects with and those without underlying osteoarthritis at baseline and knee replacement (KR) associated with meniscal surgery in subjects with and those without a reported history of preceding knee trauma. Materials and Methods The HIPAA-compliant protocol was approved by the institutional review boards of the participating centers. Written informed consent was obtained from all participants. Subjects who underwent meniscal surgery with a preceding knee trauma at baseline (n = 564) and those without (n = 147) were drawn from the Osteoarthritis Initiative cohort (n = 4796). Radiographic JSN progression was evaluated by using Osteoarthritis Research Society International grading (progression in 1st-, 2nd-, 3rd-, 4th-, 6th-, or 8th-year radiographic findings compared with baseline). KR was assessed up to the 9th year of study (days passed from inclusion to KR or last follow-up). Cox hazard analysis was used to extract the adjusted hazard ratios (HRs) with adjustments for baseline age, sex, body mass index, physical activity, symptoms, and radiographic osteoarthritis features (Kellgren and Lawrence [KL] grade). Results Meniscal surgery with a history of preceding knee trauma was not associated with radiographic progression of JSN (adjusted HR, 0.91 [95% confidence interval {CI}: 0.78, 1.07]) or KR (adjusted HR, 1.02 [95% CI: 0.79, 1.34]; P = .854). However, meniscal surgery without a history of preceding knee trauma was associated with radiographic progression of JSN (adjusted HR, 1.27 [95% CI: 1.00, 1.63]) and KR (adjusted HR, 2.09 [95% CI: 1.52, 2.89]; P < .001). Additionally, there was a higher risk of KR in subjects with radiographic KL grade of less than 2 (adjusted HR, 6.97 [95% CI: 3.56, 13.64]; P < .001) at baseline in comparison with KL grade of at least 2 (adjusted HR, 1.76 [95% CI: 1.22, 2.54]; P < .05). Conclusion In contrast to subjects without a reported preceding trauma, meniscal surgery is not independently associated with increased risk of radiographic JSN progression and KR in patients with a reported preceding trauma.
