Purpose The aim of this prospective study was to compare and correlate clinical, MRI, and arthroscopic findings in cases of suspected meniscal tears. Using arthroscopic findings as the gold standard, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of clinical investigation and MRI were evaluated to determine if is possible, after a careful examination, to bypass MRI and perform directly arthroscopy in suspected cases. Methods A total of 80 patients with a history of knee trauma, preoperative RX, and MRI underwent arthroscopy over an 8-month period at our department. All patients had a clinical examination performed by an experienced knee surgeon. These examiners evaluated and recorded the results of three tests: medial and lateral joint line tenderness test, McMurray's test, and Apley's test. The injury was classified as a meniscal tear if there were at least two positive tests. Finally, using the arthroscopic findings as the gold standard, sensibility, specificity, accuracy, positive and negative predictive values of clinical examination, and MRI were evaluated and compared. Results Clinical examination performed by an experienced knee surgeon reported better sensitivity (91 vs. 85%), specificity (87 vs. 75%), accuracy (90 vs. 82%), positive predictive value (94 vs. 88%), and negative predictive value (81 vs. 71%) than MRI for medial meniscal tears. These parameters showed minimal differences for lateral meniscal tears. Conclusion Clinical examination performed by an experienced knee surgeon provided equal or better results to diagnose meniscal injuries in comparison to MRI. MRI is not necessary to confirm these lesions and should not be used as the primary diagnostic tool. Level of Evidence Level II, prospective study.

Background and Aims: Distortions and contusions of the knee are common. Fairly often they will result in hemarthrosis. The purpose of this study was to evaluate the findings in patients with acute traumatic hemarthrosis of the knee and based on these findings estimate the necessity of acute arthroscopic examination. Material and Methods: A total of 320 patients were examined arthroscopically between the years 1994 to 96 in the Turku University Hospital. Patients with other than chondral or osteochondral fractures were excluded. Results: The most common arthroscopic findings were rupture of the ACL (45 %), dislocation of the patella (23 %) and meniscal tear (21 %). In only 113 (35 %) cases an immediate therapeutic procedure was performed in addition to the arthroscopic examination. Conclusions: Based on our findings we believe that routine arthroscopic examination is not necessary in patients with acute traumatic hemarthrosis of the knee. In our opinion the patient should be examined and followed by an orthopedic surgeon and if a lesion requiring operative treatment is diagnosed or suspected, an arthroscopic examination should be scheduled. The timing of the procedure should be such that all possible lesions encountered can be treated in the same operation.

Objectives: The initial clinical presentation of the discoid lateral meniscus (DLM) in children is highly variable and can be difficult to assess. The aim of this study was to focus on the meniscal instability associated with DLM and to correlate clinical, MRI and arthroscopic data. Methods: Between 2008 and 2018, 93 children and adolescents with 114 DLMs who underwent surgery in a referral center were included. Based on the anamnesis and clinical data, three types of meniscal instability of increasing severity were defined: occasional ("lock"), regular ("clock") and permanent ("block") instability. These findings were correlated with preoperative MRI data and arthroscopic findings according to Ahn’s classification, and as a result we were able to propose a DLM classification based on clinical or MRI data or both combined. Results: A wide variety of presentations was noted with 18 different types when clinical, MRI and arthroscopic characteristics were combined. 94% of the symptomatic DLMs for which surgery was performed showed instability due to meniscocapsular separation. Clinically, there were "lock", "clock" and "block" instability in 2%, 50% and 31% of DLMs respectively. Preoperative MRI indicated no meniscal shift and an anterocentral, posterocentral or central shift in 41%, 9%, 22% and 28% of the DLMs, respectively. Arthroscopic findings indicated no lesions, or an MC-A, MC-P or PLC type lesion in 6%, 46%, 15% and 33% of DLMs respectively. The most frequent presentations were “clocked” knees with MC-A lesions and “blocked” knees with PLC lesions. Only in 60% of the cases was a good level of correspondence noted between the different data. Conclusion: The association of meniscal instability and symptomatic DLM in children should be accepted as a certainty. “Locked”, “clocked” and “blocked” knees could represent different stages of increasing severity in the natural history of DLM instability.

Abstract Background: It remains unclear what percentage of isolated meniscal tears deteriorates before surgery, especially in older patients. We aimed to evaluate the preoperative deterioration of an isolated meniscal tear in patients aged 40 years or older, and whether time from injury to surgery is associated with worsening of a meniscal tear.Methods: Patients aged 40 years or older who underwent arthroscopic surgery for isolated meniscal tear between 2014 and 2019 were retrospectively reviewed. The diagnostic magnetic resonance imaging (MRI) findings and arthroscopic findings were compared to evaluate the deterioration of meniscal tears. Predictors of the development of meniscal tears; patient demographic factors, duration from injury to surgery (injury to MRI and MRI to surgery), and image findings were assessed. Results: A total of 58 patients (58 knees) were included (mean age, 55.9 ± 8.5 years; male/female, 31/27). An isolated meniscal tear deteriorated in 28 (48.3%). In comparison of patients with and without deteriorated meniscal tear, significant differences were found in the MRI grade of meniscal tear (p = 0.03), duration from injury to MRI (164.2 ± 167.9 vs. 45.2 ± 48.7 days, p < 0.001), and from MRI to surgery (148.8 ± 91.1 vs. 67.6 ± 56.7 days, p < 0.001). A multivariate regression analysis showed that the duration from injury to MRI (odds ratio [OR], 1.03; p < 0.001) and from MRI to surgery (OR, 1.02; p < 0.001) were independent predictors of worsening of a meniscal tear. Conclusions: Approximately 50% of isolated meniscal tears deteriorated preoperatively in patients aged 40 years or older. The duration from injury to MRI and from MRI to surgery were independent predictors of the preoperative worsening of an isolated meniscal tear in this cohort.
