Unexpected Findings

A 7-year-old boy presented with a 1-week history of a limp, low grade temperature and mildly elevated inflammatory markers. He sustained a fall 2 weeks ago but was relatively symptom free for a week. The inital physical exam demonstrated a knee effusion clinically, radiographs did not demonstrate any overt pathology and biochemical testing demonstrated an elevated C reactive protein of 8 mg/L. An arthroscopy was conducted, with a plan for synovial biopsies to investigate for infective versus inflammatory arthritis as a cause for the effusion. An isolated lateral meniscal tear was discovered. This was repaired using all inside technique with Smith and Nephew’s FastFix 360 (R) suture anchors. It is quite uncommon to find isolated lateral meniscus tears in this population, but the learning point demonstrates it is important to arthroscopically examine the whole knee, even while performing synovial biopsies as there may be unexpected findings.

Meniscal Pathology

Objectives: Recent studies have described increased risk of OA following ACL reconstruction (ACLR). Systematic reviews have suggested that meniscal pathology, which occurs in up to 60% of patients with ACL injury, increases this risk. The literature reports a 50% incidence of OA following medial meniscectomy, two times the risk compared to lateral meniscectomy. The purpose of this study was to determine the influence of meniscal pathology on the incidence of OA following ACLR. Methods: All patients who underwent primary autograft or allograft BPTB transtibial ACLR by a single surgeon between 1999-2015 were identified. Revision ACLR, multi-ligamentous reconstructions, and patients with less than 2-year imaging follow-up were excluded. Meniscus pathology and treatment were recorded. OA was defined at follow-up as Kellgren-Lawrence grade III-IV on plain radiographs. Chi-square tests assessed differences in incidence rates (p<0.05). Results: A consecutive series of 103 patients (56 males, 47 females; age 36.1±11.4 years) with BPTB ACLR with an average follow-up of 8.81±4.96 (range 2-20 years) were included. The prevalence of medial meniscus tears at the time of ACL injury was 47.6% (49/103) and prevalence of lateral meniscus tears was 56.3% (58/103) (p=0.166). Medial compartment OA was seen in 9.7% (10/103) of patients. Prevalence of medial compartment OA was greater in patients with medial meniscus tear (14.3%; 7/49) compared to those without a medial meniscus tear (5.6%; 3/54); however, this was not significant (p=0.135). Of the 7 patients with medial meniscal tear and medial compartment OA, 5 underwent partial medial meniscectomy and 2 underwent repair. Lateral compartment OA was seen in 14.6% (15/103). The prevalence of lateral compartment OA was greater in patients with a lateral meniscus tear (22.4%; 13/58) compared to patients without lateral meniscus tears (4.4%; 2/45) (p=0.01). Patients with lateral meniscus tear were 5.04 [95%CI: 1.2 to 21.2] times more likely to develop OA. Thirteen of the 47 (28%) patients that underwent partial lateral meniscectomy developed lateral OA compared to 0% of patients (0/10) that underwent lateral meniscal repair (p=0.068). Conclusion: While studies with multiple surgeons and rehabilitation protocols have shown the development of OA following ACLR is increased with medial meniscal pathology, we found that the prevalence of medial OA was not significantly higher in these patients with medial meniscal tear at an average of 8.81 years follow-up. Whereas, lateral meniscal repair dramatically reduced the development of knee OA compared to partial meniscectomy in this cohort of patients with ACLR. These findings can inform clinical practice as despite prior literature indicating a relationship between medial meniscal tear and osteoarthritis, we did not see a greater prevalence of OA amongst patients undergoing ACLR with a medial meniscal tear. Further, a lateral meniscal repair offers superior protection against OA when compared to partial lateral meniscectomy in treating lateral meniscal tears and is essential in the treatment of these complex patients.

Background: Anterior cruciate ligament (ACL) tears are frequently associated with meniscal injury. Numerous authors have described associations between the presence of a meniscal tear at the time of ACL reconstruction and time to surgery and number of instability episodes1-3. The purpose of this study was to evaluate the relationship between age and the presence of a meniscal tear at the time of ACL reconstruction in children and adolescents. Methods: A single-institution retrospective review was performed of consecutive pediatric and adolescent patients who underwent ACL reconstruction over a 3.5-year period at a single institution. Inclusion criteria were age less than 20 years and an ACL injury treated with knee arthroscopy and ACL reconstruction. Patients with multiligament knee injuries were excluded. A chart review was performed to obtain demographic information and intra-operative findings. Meniscus tears were defined as tears documented during diagnostic arthroscopy. Results: Four hundred sixty-one patients met inclusion criteria, including 226 males (49%) and 235 females (51%) with a mean age of 15 years (range 7 – 20 years). The right and left knees were affected equally. Two hundred seventy patients (80%) had intra-operative evidence of a meniscal tear, including 215 lateral meniscus tears (56%) and 119 medial meniscus tears (44%). Sixty-four patients (14%) had both medial and lateral meniscus tears. Age at surgery was found to be a statistically significant independent predictor of the presence of a meniscus tear, odds ratio=1.14, 95% CI (1.05 – 1.25), p=0.003. For every 1-year increase in age, there is a 14% increase in the odds of having a meniscus tear and this is depicted in the figure below. Among patients 13 years of age and younger (n = 89), 47% had a meniscus tear. In contrast, 62% of patients 14 – 19 years of age (n = 301) had a meniscus tear, which was significantly greater (p = 0.01). Age was also a statistically significant independent predictor following subgroup analysis of medial and lateral meniscus tears. For every one year increase in age at surgery, there was a 21% increase in the odds of having a medial meniscus tear (odds ratio = 1.21, 95% CI: (1.08 – 1.35), p<0.001) and a 13% increase in the odds of having a lateral meniscus tear (odds ratio = 1.13, 95% CI: (1.04 – 1.24), p=0.01. Conclusions: Among children and adolescents with anterior cruciate ligament tears, for every 1-year increase in age, there is a 14% increase in the odds of having a meniscus tear. Adolescents over the age of 13 years had a significantly greater rate of meniscus tears than did those 13 years of age and younger. A complete arthroscopic examination with close attention to the menisci is required to diagnose and treat meniscal tears. Surgeons should be comfortable with all meniscus repair techniques, including inside-out, outside-in, all-inside, radial, and transosseous root repairs as the majority of children and adolescent patients with ACL tears also have an associated meniscus tear.

Discoid Medial Meniscus

Background. A discoid meniscus is a thickened variant of the normal C-shaped meniscus prone to injury. Discoid medial meniscal tears have rarely been reported within families and may suggest familial or developmental origins.Methods. We report the cases of two Caucasian brothers with symptomatic discoid medial meniscus tears. A literature review was conducted addressing discoid medial meniscus and cases of familial meniscus tears.Case Presentation. Physically active brothers presented with progressively worsening knee pain. MRI revealed medial meniscus tears in both brothers. The family history of medial meniscus tears in their mother and the discoid medial meniscus injuries found on arthroscopy suggested evidence for familial discoid medial meniscus tears.Conclusions. Discoid medial meniscus tears within a family have not been previously reported. Two cases of families with discoid lateral meniscus tears have been reported. Discoid medial meniscus is rare relative to the discoid lateral meniscus and predisposes children to symptomatic tears.

Background: Acute anterior cruciate ligament(ACL) rupture is associated with a significant incidence of concomitant meniscal and chondral injuries. However, to our knowledge, the incidence of these concomitant injuries in skeletally immature(SI) versus skeletally mature(SM) patients has not been directly compared. SI patients are a unique subset of ACL patients because surgical considerations are different, and subsequent re-tear rates are high. However, it is unclear if the rates and types of meniscal and chondral injuries differ. Purpose: The purpose of this study is to compare associated meniscal and chondral injury patterns between SI and SM patients under age 21, treated with ACL reconstruction for an acute ACL tear. We hypothesized that no significant differences would be seen. Methods: We performed a single-center retrospective review of primary ACL reconstructions performed from January 2012 to April 2020. Patients were stratified by skeletal maturity status based on a review of records and imaging. Demographic data was recorded, including age, sex, and BMI. Associated intra-articular meniscal injury, including laterality, location, configuration, and treatment were determined. Articular cartilage injury location, grade, and treatments were determined. Revision rates, non-ACL reoperation rates, and time to surgery were also compared between the two groups. Results: 785 SM and 208 SI patients met inclusion criteria. Mean BMI and mean age were significantly different between groups. Meniscal tear rates were significantly greater in SM versus SI patients in medial meniscus tears(P<.001), medial posterior horn tears(P=.001), medial longitudinal tears configuration(P=.007), lateral Radial configuration(P=.002), and lateral complex tears(P=.011). Medial repairs(P<.001) and lateral partial meniscectomies(P=.004) were more likely in the SM group. There was a significantly greater number of chondral injuries in the SM versus SI groups in the Lateral(p=.007) and medial compartments(P<.001). SM patients had a significantly increased number of outerbridge grade 1 and 2 in the Lateral(P<.001) and Medial Compartments(P=.013). ACL revisions(P=.019) and Non-ACL reoperations(P=.002) were significantly greater in the SI patients compared to SM. No other significant differences were noted. Conclusion: SM ACL injured patients have a significantly higher rate of medial meniscus tears and medial longitudinal configurations treated with repair, and a significantly higher rate of radial and/or complex lateral meniscus tears treated with partial meniscectomy compared to the SI group. We also found a significantly higher rate of both medial and lateral compartment chondral injuries, mainly grades 1 and 2, in SM compared to SI patients. Conversely, SI ACL reconstruction patients had higher revision and subsequent non-ACL surgery rates.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9–715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5–12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.

Abstract Introduction Chronic inflammation is associated with the development, progression and long-term complications of type 2 diabetes. Hyperglycemia is associated with chronic low-grade inflammation, and thus has become the focus of many screening and treatment recommendations. We hypothesize that insulin may also be associated with inflammation and may be an additional factor to consider in screening and treatment. Methods This study used National Health and Nutrition Examination Survey data from 2005 to 2010 to analyze the association between fasting insulin and C-reactive protein (CRP). A two-part model was used due to the high number of values reported as 0.1 mg/L. Two models were analyzed, both with and without the addition of waist circumference to other covariates in the model. Results The final sample included 4527 adults with a mean age of 43.31 years. In the first model, higher fasting insulin was associated with increased odds of CRP > 0.1 mg/L (OR = 1.02, p < .001) and with higher CRP (β = 0.03, p < .001). In the adjusted model, including waist circumference as a covariate, higher fasting insulin was not associated with CRP > 0.1 mg/L (OR = 1.00, p = .307) but the association between higher fasting insulin and higher continuous CRP remained significant (β = 0.01, p = .012). Conclusion This study found that higher fasting insulin is associated with higher CRP. These results suggest that treatment approaches that simultaneously decrease insulin levels as well as glucose levels may provide additive anti-inflammatory effects, and therefore may improve long-term outcomes for adults with type 2 diabetes.

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.

It has been suggested that Type 2 diabetes may, in part, be precipitated or accelerated by an acute-phase reaction as part of the innate immune response, in which large amounts of cytokines are released from adipose tissue, creating a low-grade inflammatory milieu. There is also firm evidence that atherosclerosis is an immune-mediated inflammatory disease. Therefore it is reasonable to imply that low-grade inflammation is an important pathogenetic factor in atherosclerosis and cardiovascular events in patients with Type 2 diabetes. Over the last few years, there have been a lot of promising clinical markers proposed to link inflammation and atherosclerosis. Of these markers, hs-CRP (high-sensitivity C-reactive protein) might be a prognostic marker for further cardiovascular events, although this has been refuted recently. In this issue of Clinical Science, Castoldi and co-workers have demonstrated that, in patients with Type 2 diabetes categorized into low (<1.0 mg/l), medium (1.0–3.0 mg/l) and high (>3.0 mg/l) hs-CRP groups, serum levels of hs-CRP correlated with lipopolysaccharide-stimulated release of interleukin-1β and interleukin-6 in whole blood. This finding may indicate that low-grade inflammatory activity might influence cytokine production in these patients.

Primary arthritis of chondrosternal joint is very rare and occurs in infants less than 18 months of age. Presentation is most often subacute but may be acute. Child presents with a parasternal mass with history of fever and/or local signs of infection. Clinical symptoms vary from a painless noninflammatory to a painful mass with local tenderness and swelling, while fever may be absent. Laboratory data show low or marginally raised levels of white blood cells and C-reactive protein, reflecting, respectively, the subacute or acute character of the infection. It is a self-limiting affection due to the adequate immune response of the patient. Evolution is generally good without antibiotherapy with a progressive spontaneous healing. A wait-and-see approach with close follow-up in the first weeks is the best therapeutic option.
