A lateral meniscus tear incarcerated behind the popliteus tendon: A case report

Background: Meniscal cysts were rare case. There’s a 50 to 100% chance forming cyst to the tear if there was an injury happens. Trauma would cause tears happen in meniscus, leads to formation of hemorrhage which formed mucoid degeneration. The necrosis happens locally plus degeneration of mucoid forming a cyst. Thus, the meniscal cysts challenge the clinician to have clinical reasoning so then the patient can get accurate diagnosis and preferred management. Method: This paper is a case report of surgery on a patient present with cysts on lateral para meniscus which done arthroscopically with all inside technique. Results: The procedure which done by arthroscope and motorized shaver had a great outcome in this patient which were analyze from Visual Analog Scale (VAS) and Western Ontario and McMaster Index (WOMAC) 3 months after the procedure, and reach VAS score of 2/10 which was mild pain and 59,8 in WOMAC score. Conclusion: The arthroscopy and all inside technique with motorized shaver is a choice of lateral para meniscal cysts surgery with good results to be considered by orthopedic surgeons. Key words: Lateral, Meniscus Tear, Parameniscal cyst, Arthroscopy.

AbstractTenosynovial giant cell tumors (TSGCT) are benign tumors originating from the synovial joint, bursa, or tendon sheath. Localized pigmented villonodular synovitis (PVNS), a subtype of TSGCT, commonly affects the hands and feet and has also been reported in the literature in the knee joint. There is sparse literature on localized PVNS arising specifically from meniscal tissue. We present a case report of a 17-year- old male with symptoms and MRI findings consistent with a lateral meniscus tear. Intraoperatively, the patient was found to have a mass originating from the torn meniscal tissue, which was confirmed by pathology to be a TSGCT. We performed a literature review of intra-articular localized PVNS within the knee presenting as a meniscal tear.

The Stability

Introduction: Although uncommon, the discoid meniscus is quite prone to injury due to its abnormal shape and abnormal histology. The weak or absent peripheral attachment of the discoid meniscus causes instability even after partial meniscectomy. Therefore, recently, after resection of the central part of the meniscus, in which tears develop most frequently, the remnant of the meniscus is preferred to repair. In that time, the Watanabe classification, which classifies the discoid meniscuses in three groups, is used to plan treatment. However, discoid meniscus can develop in the different forms from these three main shapes. In the present study we aimed to analyse the discoid meniscuses, which we encountered during arthroscopic procedures in the knee, according to Watanabe classification. Patients and methods: The lateral discoid meniscuses in the 36 knees of 35 patients, who were operated on because of meniscus tear of either the discoid lateral meniscus itself or the normal medial meniscus, were classified according to Watanabe classification. Results: While the lateral discoid meniscuses were classified as “complete” in 13, “incomplete” in 15 knees, the meniscuses were very thin or absent in the central (one knee) or in the postero-lateral regions (seven knees) of discoid meniscus ( Figure 1 ). In this series this opening was next to the popliteus tendon except in one case. In these cases, the continuity of the meniscus between middle and posterior horn frequently was not possible after central partial meniscectomy (CPM). On the other hand, posterior horn has stable peripheral attachment unlike the Wrisberg type discoid meniscus. Of the 36 discoid meniscuses, CPM was performed in 21 knees, CPM with anterior horn repair in three, CPM with posterior horn repair in one and anterior horn repair without meniscectomy in two patients. In nine patients the lateral discoid meniscus was left alone. [Figure: see text] Discussion and conclusion: When meniscus sparing methods are intended to perform, both to decide the amount of resection and repair of the remnant, besides the shape of meniscus tear, the stability of discoid meniscus is crucial. This study shows that the Watanabe classification cannot be sufficient to include some specific type of lateral discoid meniscus. We believe that to add the discoid meniscuses, with opening in postero-lateral region next to the popliteus tendon, to the Watanabe classification might be useful to decide the amount of resection or repair of the discoid lateral meniscus.

Confounding Factors

Abstract Purpose To investigate the potential factors associated with the prevalence of meniscal repair Methods Patients who received partial meniscectomy or meniscal repair in our institution from Jan 2015 to Dec 2019 were included in current study. The inclusion criteria were (1) meniscus tear treated using meniscectomy or repair, (2) with or without concomitant anterior cruciate ligament reconstruction, (3) not multiligamentous injury. Demographic data, including sex, age, body mass index (BMI), injury-to-surgery interval and intra-articular factors such as the location of injury, medial or lateral, ACL rupture or not and the option of procedure (partial meniscectomy or repair) were documented from medical records. Univariate analysis consisted of chi-square. Multivariate logistic regression was then performed to adjust for confounding factors. Results 592 patients including 399 males and 193 females with a mean age of 28.7 years (range from 10 to 75 years) were included in current study. In the univariate analysis, male (p = 0.002), patients aged 40 years or younger (p < 0.001), increased weight (p = 0.010), Posterior meniscus torn (0.011), concurrent ACL ruputure (p < 0.001), lateral meniscus (p = 0.039) and early surgery (p < 0.001) were all associated with the prevalence of meniscal repair. However, After adjusting for confounding factors, we found that age (OR, 0.35; 95% CI, 0.17 - 0.68, p = 0.002), ACL injury (OR, 3.76; 95% CI, 1.97 – 7.21, p < 0.001), side of menisci (OR, 3.29; 95% CI, 1.43 – 7.55, p = 0.005), site of tear (OR, 0.15; 95% CI, 0.07 – 0.32, p < 0.001), and duration of injury (OR, 0.46; 95% CI, 0.28 – 0.82, p = 0.008) were associated with the prevalence of meniscus repair. Conclusions Meniscal tear in aged patients especially those with concomitant ACL injury is likely to be repaired. Additionally, in order to increase the prevalence of repair and slow down progression of OA, the surgical procedure should be performed within two weeks after meniscus tear especially when the tear is located at lateral meniscal posterior. Study design Case-control study; level of evidence, 3.
