Abstract
PURPOSE We aimed to evaluate whether tears of the posterior horn of the medial meniscus root ligament (PHMM RL) are associated with osteoarthritis of the far posterior femoral condyles (FPFC). METHODS Retrospective review of 1158 patients who underwent arthroscopy identified 49 patients with confirmed tears of the medial meniscus posterior root ligament attachment. Preoperative magnetic resonance imaging (MRI) studies were reviewed to identify advanced osteoarthritis involving the medial and lateral FPFC. Control patients (n=48) had no meniscal tears confirmed by arthroscopy. Cases and controls were age- and sex-matched exactly 1:1. One case patient was excluded since there was no age- and sex-matched control available. The International Cartilage Research Society (ICRS) MRI cartilage grade was recorded for the medial and lateral FPFC. Associations were evaluated using univariate and multivariable conditional logistic regression analyses. RESULTS There were 48 case and 48 control patients (10 men in each group, 20.8%) with median age 53 years (range, 21-67). Medial FPFC ICRS Grade 2 or higher lesions were present in 34 (70.8%) of case patients and 16 (33.3%) of control patients. Lateral FPFC ICRS Grade 2 or higher lesions were present in 24 (50%) of case patients and 14 (28.2%) of control patients. Increased body mass index (BMI) was associated with PHMM RL tears (OR=1.11, 95% CI [1.01, 1.22], P = 0.020). MRI was 81.2% (39/48) sensitive and 91.2% (44/48) specific for detection of PHMM RL tears. PHMM RL tears were associated with Grade 2 or higher medial FPFC osteoarthritis (OR=10.00, 95% CI (2.34, 42.78), P < 0.001). This association remained after adjusting for BMI (OR=11.79, 95% CI [2.46, 56.53], P = 0.002). There was also an association between PHMM RL tears and lateral FPFC osteoarthritis, which persisted after adjusting for BMI (OR =3.00, 95% CI [1.07, 8.37], P = 0.036). CONCLUSION PHMM RL tears are associated with advanced osteoarthritis of the FPFC. Radiologists identifying FPFC osteoarthritis should look carefully for PHMM RL tears.

Abstract
PURPOSE The importance of meniscus integrity in the prevention of early osteoarthritis is well known, and preservation is accepted as the primary goal. The purpose of the ESSKA (European Society for Sports Traumatology, Knee Surgery and Arthroscopy) European consensus on traumatic meniscus tears was to provide recommendations for the treatment of meniscus tears based on both scientific evidence and the clinical experience of knee experts. METHODS Three groups of surgeons and scientists elaborated and ratified the so-called formal consensus process to define the recommendations for the management of traumatic meniscus tears. A traumatic meniscus tear was defined as a tear with an acute onset of symptoms caused by a sufficient trauma. The expert groups included a steering group of eight European surgeons and scientists, a rating group of another nineteen European surgeons, and a peer review group. The steering group prepared twenty-seven question and answer sets based on the scientific literature. The quality of the answers received grades of A (a high level of scientific support), B (scientific presumption), C (a low level of scientific support) or D (expert opinion). These question and answer sets were then submitted to and evaluated by the rating group. All answers were scored from 1 (= totally inappropriate) to 9 (= totally appropriate) points. Thereafter, the comments of the members of the rating group were incorporated by the steering group and the consensus was submitted to the rating group a second time. Once a general consensus was reached between the steering and rating groups, the finalized question and answer sets were submitted for final review by the peer review group composed of representatives of the ESSKA-affiliated national societies. Eighteen representatives replied. RESULTS The review of the literature revealed a rather low scientific quality of studies examining the treatment of traumatic meniscus tears. Of the 27 questions, only one question received a grade of A (a high level of scientific support), and another received a grade of B (scientific presumption). The remaining questions received grades of C and D. The mean rating of all questions by the rating group was 8.2 (95% confidence interval 8.1-8.4). A general agreement that MRI should be performed on a systematic basis was not achieved. However, MRI was recommended when arthroscopy would be considered to identify concomitant pathologies. In this case, the indication for MRI should be determined by a musculoskeletal specialist. Based on our data, stable left in situ lateral meniscus tears appear to show a better prognosis than medial tears. When repair is required, surgery should be performed as early as possible. Evidence that biological enhancement such as needling or the application of platelet-rich plasma would improve healing was not identified. Preservation of the meniscus should be considered as the first line of treatment because of an inferior clinical and radiological long-term outcome after partial meniscectomy compared to meniscus repair. DISCUSSION The consensus was generated to present the best possible recommendations for the treatment of traumatic meniscus tears and provides some groundwork for a clinical decision-making process regarding the treatment of meniscus tears. Preservation of the meniscus should be the first line of treatment when possible, because the clinical and radiological long-term outcomes are worse after partial meniscectomy than after meniscus preservation. The consensus clearly states that numerous meniscus tears that were considered irreparable should be repaired, e.g., older tears, tears in obese patients, long tears, etc. LEVEL OF EVIDENCE: II.

Abstract
Objective: The purpose of this study was to assess the effects of the Mulligan Concept (MC) 'squeeze' technique compared to a sham technique in participants with a clinically diagnosed meniscal tear. Methods: A multi-site randomized sham-controlled trial of participants (n = 23), aged 24.91 ± 12.09 years, with a clinically diagnosed meniscal tear were equally and randomly divided into two groups. Groups received a maximum of six treatments over 14 days. Patient outcomes included the numeric pain rating scale (NRS), patient-specific functional scale (PSFS), the disablement in the physically active (DPA) scale and the knee injury osteoarthritis outcome score. Data were analysed using univariate ANOVA, univariate ANCOVA, and descriptive statistics. Results: All participants in the MC 'squeeze' group met the discharge criteria of ≤2 points on the NRS, ≥9 points on the PSFS, and ≤34 points or ≤23 on the DPA Scale for chronic or acute injuries, respectively within the treatment intervention timeframe. A significant difference was found in favor of the MC 'squeeze' technique in PSFS scores (F(1, 21) = 4.40, p = .048, partial eta squared = .17, observed power = .52) and in DPA Scale scores (F(1, 21) = 7.46, p = .013, partial eta squared = .27, observed power = .74). Discussion: The results indicate the MC 'squeeze' technique had positive effects on patient function and health-related quality of life over a period of 14 days and was clinically and statistically superior to the sham treatment. Further investigation of the MC 'squeeze' technique is warranted.

Abstract
Objective The purpose of this case study was to report on the immediate effects of the combined use of mobilizations with movement and the "squeeze" technique on a patient with knee stiffness, popping, and swelling. Clinical Features The patient presented with right knee stiffness, swelling, and a popping sensation of insidious onset. Clinical examination revealed pain with terminal knee extension and flexion, joint line tenderness, a positive Apley's compression test, and a positive Thessaly's test at 20° of knee flexion. A working diagnosis was established of a meniscal pathology with the differential diagnoses of meniscal derangement and synovial plica. Intervention and Outcome The patient received 3 total treatments using the Mulligan concept over the course of 11 days. The treatments included the application of a tibia internal rotation mobilization with movement and the "squeeze" technique to the affected knee. Patient outcomes, including the Disablement in the Physically Active Scale, the Patient-Specific Functional Scale, and the Numeric Rating Scale for pain, were collected throughout the course of treatment. The patient reported a minimal clinically important difference on the Numeric Rating Scale for pain after each treatment and on all outcomes after the third treatment. The patient reported improvement on her follow-up visit 4 days after the third treatment; the results of a clinical exam and patient outcomes supported a complete discharge after 3 treatments. Conclusion This patient responded favorably to use of the Mulligan concept as a manual therapy technique for the treatment of symptoms related to possible meniscal derangement.

Abstract
The knee is one of the most commonly injured joints in the body. Its superficial anatomy enables diagnosis of the injury through a thorough history and physical examination. Examination techniques for the knee described decades ago are still useful, as are more recently developed tests. Proper use of these techniques requires understanding of the anatomy and biomechanical principles of the knee as well as the pathophysiology of the injuries, including tears to the menisci and extensor mechanism, patellofemoral conditions, and osteochondritis dissecans. Nevertheless, the clinical validity and accuracy of the diagnostic tests vary. Advanced imaging studies may be useful adjuncts.

Abstract
Background Meniscus tears are the most common injury of the knee. The McMurray's test and Joint line tenderness for diagnosing meniscus tear have been widely tested, but results reported by different authors vary. The wide variations reported have an impact on clinical decision concerning whether to go for other diagnostic tests before going for diagnostic arthroscopy, which is considered as the gold standard.The purpose of this study was to determine the diagnostic value of Joint line tenderness and McMurray's test, as clinical signs, to diagnose underlying medial meniscus tears. Methods This was a prospective observational study done in Tribhuwan University Teaching Hospital. Patients undergoing knee arthroscopy were included in the study period of one year (from February 2011 to January 2012). Each patient was clinically examined with McMurray's test and joint line tenderness. The findings were then matched by the arthroscopic findings. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were then calculated. Results The sensitivity, specificity, positive predictive value , negative predictive value and accuracy for medial joint line tenderness in diagnosing medial meniscus tear were 50%, 61.7%, 51.8%, 60% and 56.45% respectively. The result was insignificant (p value=0.352). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for McMurray's test for diagnosing medial meniscus tear were 54%, 79%, 68% , 67.50% and 67.74% respectively. The result was significant (p value=0.007). Conclusion Clinical tests like McMurray and joint line tenderness have low diagnostic value when applied individually. They may be useful when combined together with the background of clinical history. The decision to scope the knee should not be solely taken on the results of clinical tests.

Abstract
BACKGROUND Partial meniscectomy does not consistently produce the desired positive outcomes intended for meniscal tears lesions; therefore, a need exists for research into alternatives for treating symptoms of meniscal tears. The purpose of this case series was to examine the effect of the Mulligan Concept (MC) "Squeeze" technique in physically active participants who presented with clinical symptoms of meniscal tears. DESCRIPTION OF CASES The MC "Squeeze" technique was applied in five cases of clinically diagnosed meniscal tears in a physically active population. The Numeric Pain Rating Scale (NRS), the Patient Specific Functional Scale (PSFS), the Disability in the Physically Active (DPA) Scale, and the Knee injury and Osteoarthritis Outcomes Score (KOOS) were administered to assess participant pain level and function. OUTCOMES Statistically significant improvements were found on cumulative NRS (p ≤ 0.001), current NRS (p ≤ 0.002), PSFS (p ≤ 0.003), DPA (p ≤ 0.019), and KOOS (p ≤ 0.002) scores across all five participants. All participants exceeded the minimal clinically important difference (MCID) on the first treatment and reported an NRS score and current pain score of one point or less at discharge. The MC "Squeeze" technique produced statistically and clinically significant changes across all outcome measures in all five participants. DISCUSSION The use of the MC "Squeeze" technique in this case series indicated positive outcomes in five participants who presented with meniscal tear symptoms. Of importance to the athletic population, each of the participants continued to engage in sport activity as tolerated unless otherwise required during the treatment period. The outcomes reported in this case series exceed those reported when using traditional conservative therapy and the return to play timelines for meniscal tears treated with partial meniscectomies.

Abstract
BACKGROUND Musculoskeletal knee pain is a large and costly problem, and meniscal tears make up a large proportion of diagnoses. ‘Special tests’ to diagnose torn menisci are often used in the physical examination of the knee joint. A large number of publications within the literature have investigated the diagnostic accuracy of these tests, yet despite the wealth of research their diagnostic accuracy remains unclear.Aim To synthesise the most current literature on the diagnostic accuracy of special tests for meniscal tears of the knee in adults. METHOD An electronic search of MEDLINE, Cumulative Index to Nursing and Allies Health Literature (CINAHL), The Allied and Complementary Medicine Database (AMED) and SPORT Discus databases was carried out from inception to December 2014. Two authors independently selected studies and independently extracted data. Methodological quality was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS) 2 tool. RESULTS Nine studies were included (n=1234) and three special tests were included in the meta-analysis. The methodological quality of the included studies was generally poor. McMurray’s had a sensitivity of 61% (95% CI 45% to 74%) and a specificity of 84% (95% CI 69%to 92%). Joint line tenderness had a sensitivity of 83%(95% CI 73% to 90%) and a specificity of 83% (95% CI 61% to 94%). Thessaly 20° had a sensitivity of 75%(95% CI 53% to 89%) and a specificity of 87% (95% CI 65% to 96%). CONCLUSIONS The accuracy of the special tests to diagnose meniscal tears remains poor. However, these results should be used with caution, due to the poor quality and low numbers of included studies and high levels of heterogeneity.

Abstract
STUDY DESIGN Diagnostic accuracy study. OBJECTIVE To evaluate the diagnostic accuracy of the Thessaly test compared with an arthroscopic examination in patients with suspected meniscal tears. BACKGROUND The Thessaly test was introduced to improve the diagnostic accuracy of the clinical examination in detecting meniscal tears. This test appears to be a valuable alternative to other meniscal clinical tests usually performed, but additional diagnostic accuracy data are required. METHODS Patients with suspected meniscal tears, referred to a hospital for arthroscopic surgery, were eligible. The Thessaly test alone and the combination of the Thessaly and McMurray tests were considered as index tests, and arthroscopy was used as the reference test. Experienced physical therapists performed the Thessaly test at 20° of flexion and the McMurray test for both knees. The physical therapist was blinded to patient information, the affected knee, and the results from possible earlier diagnostic imaging. An orthopaedic surgeon blinded to the clinical test results from the physical therapist performed the arthroscopic examination. RESULTS A total of 593 patients were included, of whom 493 (83%) had a meniscal tear, as determined by the arthroscopic examination. The Thessaly test had a sensitivity of 64% (95% confidence interval [CI]: 60%, 68%), specificity of 53% (95% CI: 43%, 63%), positive predictive value of 87% (95% CI: 83%, 90%), negative predictive value of 23% (95% CI: 18%, 29%), and positive and negative likelihood ratios of 1.37 (95% CI: 1.10, 1.70) and 0.68 (95% CI: 0.59, 0.78), respectively. The combination of positive Thessaly and McMurray tests showed a sensitivity of 53% and specificity of 62%. CONCLUSION The results of the Thessaly test alone or combined with the McMurray test do not seem useful to determine the presence or absence of meniscal tears. LEVEL OF EVIDENCE Diagnosis, level 2b.

Abstract
PURPOSE This study aims to identify and summarize the evidence on the biomechanical parameters and the corresponding technologies which have been used to quantify the pivot shift test during the clinical and functional assessment of anterior cruciate ligament (ACL) injury and surgical reconstruction. METHODS Search strategy Internet search of indexed scientific articles on the PubMed database, Web of Science and references on published manuscripts. No year restriction was used. Selection criteria Articles included were written only in English and related to search terms: "pivot shift" AND (OR "ACL"). The reviewers independently selected only those studies that included at least one quantitative parameter for the analysis of the pivot shift test, including both in vitro and in vivo analyses performed on human joint. Those studies that analysed only clinical grading were excluded from the analysis. Analysis After evaluating the methodological quality of the articles, the parameters found were summarized. RESULTS Six hundred and eight studies met the inclusion criteria, and finally, 68 unique studies were available for the systematic review. Quantitative results were heterogeneous. The pivot shift test has been quantified by means of 25 parameters, but most of the studies focused on anterior-posterior translations, internal-external rotation and acceleration in anterior-posterior direction. CONCLUSION Several methodologies have been identified and developed to quantify pivot shift test. However, clinical professionals are still lacking a 'gold standard' method for the quantification of knee joint dynamic laxity. A widespread adoption of a standardized pivot shift manoeuvre and measurement method to allow objective comparison of the results of ACL reconstructions is therefore desirable. Further development of measurement methods is indeed required to achieve this goal in a routine clinical scenario.

Joint line tenderness and McMurray tests for the detection of meniscal lesions: what is their real diagnostic value? Arch Phys Med Rehabil 2012; 94:1126-31. [PMID: 23154135 DOI: 10.1016/j.apmr.2012.11.008] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2012] [Revised: 11/05/2012] [Accepted: 11/05/2012] [Indexed: 12/29/2022]
Abstract
OBJECTIVES To assess the interobserver concordance of the joint line tenderness (JLT) and McMurray tests, and to determine their diagnostic efficiency for the detection of meniscal lesions. DESIGN Prospective observational study. SETTING Orthopedics outpatient clinic, university hospital. PARTICIPANTS Patients (N=60) with suspected nonacute meniscal lesions who underwent knee arthroscopy. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Patients were examined by 3 independent observers with graded levels of experience (>10y, 3y, and 4mo of practice). The interobserver concordance was assessed by Cohen-Fleiss κ statistics. Accuracy, negative and positive predictive values for prevalence 10% to 90%, positive (LR+) and negative (LR-) likelihood ratios, and the Bayesian posttest probability with a positive or negative result were also determined. The diagnostic value of the 2 tests combined was assessed by logistic regression. Arthroscopy was used as the reference test. RESULTS No interobserver concordance was determined for the JLT. The McMurray test showed higher interobserver concordance, which improved when judgments by the less experienced examiner were discarded. The whole series studied by the "best" examiner (experienced orthopedist) provided the following values: (1) JLT: sensitivity, 62.9%; specificity, 50%; LR+, 1.26; LR-, .74; (2) McMurray: sensitivity, 34.3%; specificity, 86.4%; LR+, 2.52; LR-, .76. The combination of the 2 tests did not offer advantages over the McMurray alone. CONCLUSIONS The JLT alone is of little clinical usefulness. A negative McMurray test does not modify the pretest probability of a meniscal lesion, while a positive result has a fair predictive value. Hence, in a patient with a suspected meniscal lesion, a positive McMurray test indicates that arthroscopy should be performed. In case of a negative result, further examinations, including imaging, are needed.

Abstract
BACKGROUND Meniscal tears have been associated with meniscal cysts and fullness of the knee joint line on physical examination. HYPOTHESIS Joint line fullness is an accurate, sensitive, and specific test to detect meniscal tears. STUDY DESIGN Prospective cohort study. METHODS One hundred consecutive patients undergoing knee arthroscopy were included. All had physical examinations documenting the presence of joint line fullness, joint line tenderness, and the McMurray sign. Arthroscopy was the gold standard for tears. Accuracy, sensitivity, and specificity were calculated and correlated with type of tear. Sixty-one patients had a magnetic resonance imaging preoperatively (the gold standard for determining the presence of a cyst). RESULTS Meniscal tears were found in 67 patients at arthroscopy. The accuracy, sensitivity, and specificity of joint line fullness were, respectively, 73%, 70%, and 82% in detecting meniscal tears; 68%, 87%, and 30% for joint line tenderness; and 47%, 32%, and 78% for the McMurray sign. The highest positive predictive value for detecting a tear was 88% for joint line fullness, compared with 77% for joint line tenderness and 76% for the McMurray sign. However, joint line fullness did not correlate well with the presence of a cyst, with a low positive predictive value (29%). Of those patients with joint line fullness on physical examination, 89% had a horizontal cleavage component of their tear at arthroscopy. CONCLUSION Joint line fullness is an accurate, sensitive, and specific test to detect meniscal tears. CLINICAL RELEVANCE The findings support the routine use of joint line fullness during physical examination along with other common tests to improve the accuracy of clinically diagnosing meniscal tears.

Abstract
OBJECTIVE In diagnosing symptomatic meniscal tear, clinicians often query patients with a "checklist" of symptoms such as "popping" or "catching." There has been little research on the reliability or diagnostic value of these terms. METHODS We developed questions to elicit the presence of 11 checklist symptoms associated with meniscal tear and administered a survey with both "checklist" and expanded descriptions to study subjects. We examined the reliability of the checklist and expanded versions of each item. Validity was evaluated in relation to the clinical diagnosis of symptomatic meniscal tear, which consisted of the clinical impression of the treating orthopedic surgeon based upon physical examination, history, and magnetic resonance imaging. We developed a Meniscal Symptom Index, calculated as the sum of those expanded descriptive items that were independently associated with symptomatic meniscal tear in multivariate logistic regression. RESULTS A total of 300 individuals (mean±SD age 52±12 years, 67% women) completed the survey. One hundred twenty-one had symptomatic meniscal tear. Test-retest reliability was higher for expanded descriptions than for checklist items. The Meniscal Symptom Index consisted of 4 expanded items: localized pain, clicking, catching, and giving way. Among the subjects with none of these symptoms, 16% (95% confidence interval [95% CI] 2%, 30%) had symptomatic meniscal tear, whereas among those with all 4 symptoms, 76% (95% CI 63%, 88%) had symptomatic meniscal tear (P for trend = 0.0001). CONCLUSION Clinicians should use expanded symptom definitions when querying patients about meniscal symptoms. A newly developed Meniscal Symptom Index holds promise as a diagnostic tool and merits further validation.

Mechanized pivot shift test achieves greater accuracy than manual pivot shift test. Knee Surg Sports Traumatol Arthrosc 2010; 18:1208-13.

Abstract
The objective of this study was to design a navigated mechanized pivot shift test setup and evaluate its repeatability in the ACL-deficient knee. It was hypothesized that translations and rotations measured with the mechanized pivot shift would be more repeatable when compared to those obtained with a manual pivot shift. Twelve fresh frozen cadaveric hip-to-toe whole lower extremities were used for this study. A manual pivot shift test was performed in the intact knee and in the ACL-deficient knee and was repeated three times. A navigation system simultaneously recorded tibial translation and rotation. The mechanized pivot shift test consists of a modified continuous passive motion (CPM) machine and a custom-made foot holder to allow for the application of internal rotation moments at the knee. Valgus moments were achieved by a 45 degrees tilt of the CPM machine with respect to the supine position and a Velcro strap secured across the proximal tibia. The mechanized pivot shift was repeated three times. Repeated measures ANOVA was used to compare manual and mechanized pivot shift testing. An intra-class correlation coefficient (ICC) was used to determine variability within each knee at each testing condition. In the ACL-deficient knee, translation with manual pivot shift testing (11.7 +/- 2.6 mm) was significantly higher than with mechanized pivot shift testing (7.4 +/- 2.5 mm; p < 0.05). Rotation with the manual pivot shift testing (18.6 +/- 5.4 degrees) was also significantly higher than with mechanized pivot shift testing (11.0 +/- 2.3 degrees; p < 0.05). The intra-class ICC for translations was 0.76 for manual pivot shift and 0.92 for the mechanized pivot shift test. The intra-class ICC for rotations was 0.89 for manual pivot shift and 0.82 for the mechanized pivot shift test. This study introduced a modified CPM for mechanized pivot shift testing. Although recorded translations and rotations with the mechanized pivot shift test were lower than with manual testing, the clinical advantage of mechanized pivot shift testing is a more repeatable measurement of ATT when compared to manual pivot shift testing. This setup may increase consistency of clinical grading of the pivot shift test.

Abstract
INTRODUCTION Clinical examination of acute knee injury in childhood is often difficult and therefore magnetic resonance imaging (MRI) serves as an additional diagnostic tool. The aim of the present study was to evaluate on the one hand the indications for diagnostic arthroscopy and on the other hand the indications for MRI. METHODS Of the children treated between 1990 and 1999, 87 (group 1) underwent arthroscopy after clinical examination. Between 2000 and 2006 (group 2) 83 patients were examined using MRI after clinical examination and 53 were subsequently submitted to arthroscopy. RESULTS In group 1 the clinical diagnosis was verified by arthroscopy in 79%. In group 2 the clinical and arthroscopic diagnoses were consistent in 60% of the patients. The MRI diagnosis was correctly recognized for patella dislocation in all cases, for ligament injuries in 83% and for meniscus injuries in 56%. Due to the application of MRI before arthroscopy the fraction of diagnostic arthroscopies could be reduced from 22% to 13%. CONCLUSION The number of diagnostic arthroscopies in childhood can be reduced by application of MRI.

Abstract
OBJECTIVE The objective of this study was to review the physical examination tests available to a practitioner in order to arrive at a clinical diagnosis or suspicion of a meniscal lesion. BACKGROUND The menisci transmit weight bearing forces and increase stability of the knee. The menisci also facilitate nutrition, provide lubrication and shock absorption for the articular cartilage and promote knee proprioception. The combinations of torsional and axial loading appear to be the cause of most meniscal injuries. Diagnosis of acute knee injuries has long been a topic for discussion throughout the orthopedic literature. Many clinical tests and diagnostic studies have been developed to increase the clinician's ability to accurately diagnose these types of disorders of the knee. CONCLUSION The accuracy of all diagnostic tests is thought to be dependant upon the skill of the examiner, and the severity and location of the injury. The multitude of tests described to assess meniscal lesions suggests that none are consistently reliable. However, recent research has focused on a composite score to accurately predict meniscus lesions. The combination of a comprehensive history, multiple physical tests and diagnostic imaging for confirmation is typical for a clinical meniscal lesion diagnosis while the gold standard remains the arthroscopic procedure itself.

Abstract
STUDY DESIGN Resident's case problem. BACKGROUND Kaposi's sarcoma (KS) is the most common form of cancer in patients with human immunodeficiency virus (HIV) infection. Although KS is often initially asymptomatic, this neoplasm may progress to affect multiple organ systems, including structures of the musculoskeletal system, which can produce symptoms similar to those associated with common orthopaedic conditions. This resident's case problem describes the evaluation and differential diagnosis of a 45-year-old male with HIV and KS, referred to physical therapy with an initial diagnosis of radiographic osteoarthritis (OA) and patellofemoral pain syndrome (PFPS) of the left knee. His primary complaint was knee pain during end range knee flexion. DIAGNOSIS The history, systems review, and examination suggested a source of pain of a nonorthopaedic origin. Differential examination ruled out clinical OA, PFPS, ligament/cartilage derangement, and tendonitis. Avascular necrosis of the medial femoral condyle was also considered as a possible source of pain. Recent blood tests indicated a high viral load and low CD4 count, which might have increased susceptibility to opportunistic infections or KS tumor progression. The patient was referred back to his physician for additional follow-up. Magnetic resonance imaging (MRI) of the knees were consistent with a systemic inflammatory process such as KS. A true-cut biopsy was subsequently scheduled, which confirmed KS lesions at the left knee. DISCUSSION Physical therapists who manage orthopaedic conditions should be aware of the disablement that may result from acquired immunodeficiency syndrome-related KS. A thorough joint-specific examination, with a broad differential diagnosis, should be employed for patients having known systemic diseases. LEVEL OF EVIDENCE Differential diagnosis, level 4.

Abstract
Clinical assessment of meniscal pathology in the knee has proven difficult due to the wide number of tests available and variations in their interpretation and application. The purpose of this paper was to assess the literature investigating the validity and diagnostic accuracy of the McMurray's test (and modifications) for determining meniscal pathology of the knee so that conclusions could be drawn regarding its clinical usefulness as a test. Electronic databases (Medline, CINhAL, AMED, SPORTSDiscus, and SCOPUS) were searched from March 1980 to May 2008. In addition, cited references of relevant articles were examined. Studies were included for analysis if they compared the McMurray's test with a gold standard of knee arthroscopy or magnetic resonance imaging (MRI). Eleven studies met the inclusion criteria. Collectively, these studies indicate that there is little consensus in the reported measures of validity of the McMurray's test and that this is mostly due to limitations in the methodological quality of the studies that were assessed. Methodological scores on the STARD (Standards for Reporting of Diagnostic Accuracy) yielded scores from 10/25 to 20/25. Generally, the McMurray's test has relatively high specificity and low sensitivity. The studies that compared the diagnostic accuracy of the McMurray's test with that of modified versions of the test showed enhanced diagnostic accuracy for the modified tests. This review identified that the McMurray's test is of limited clinical value due to relatively low sensitivity, with modified tests (associated with the traditional McMurray's test) having higher diagnostic accuracy and thus these may be more useful clinically.

Abstract
Objective: To systematically review the most recent literature with meta-analysis to summarize the accuracy of clinical tests for assessing meniscal lesions of the knee. Methods and measures: A computerized database search was performed to identify eligible articles. Identified articles were reviewed to determine eligibility and methodological quality. Sensitivity, specificity, likelihood ratios and diagnostic odd ratios were reproduced or recorded from each study. Meta-analysis was performed using the reported study sensitivity and specificity values. Results: Three tests — joint line tenderness, McMurray's and Apley's — were compared in the meta-analysis. The methodological quality of the studies was found to have a significant effect on both the test sensitivities and specificities. Summary receiver operating characteristic (ROC) curves, sensitivity values, mean likelihood ratios and diagnostic odd ratios (DOR) uniformly show joint line tenderness (DOR = 10.98) to be the best `common' test, followed by McMurray's (DOR = 3.99) and Apley's (DOR = 2.2). Thessaly's test reported the strongest DOR of 227, but samples were smaller (n = 410), than those for joint line tenderness (n = 1354), McMurray's (n = 1232) and Apley's (n = 479). Conclusion: Methodological quality varied from poor to fair among studies, affecting test performance. Future studies should, where possible, utilize larger samples of individuals without meniscal lesions to better estimate test specificity and thus more accurately identify optimal clinical tests.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVES To identify, analyze, and synthesize the literature to determine which physical examination tests, if any, accurately diagnose a torn tibial meniscus. BACKGROUND Knee pain has a lifetime prevalence of up to 45%, and as many as 31% of individuals with knee pain will consult a general practitioner. Roughly 5% of these individuals will undergo a tibial meniscectomy and many more will undergo partial meniscectomy or meniscus repair. Determining which of these individuals is appropriate for surgical consult depends on clinical examination findings. METHODS AND MEASURES We searched MEDLINE, CINAHL, and SPORTDiscus from1966 to August 2006 and extracted all English- and German-language studies that reported the diagnostic accuracy of individual physical examination tests for a torn meniscus. We retrieved data regarding true positives, false positives, true negatives, and false negatives to create 2-by-2 tables for each article and test. Like tests were then subjected to meta-analysis and subanalysis. Cochran Q test and the 12 statistic were used to examine for the presence of heterogeneity and the extent of the effect of heterogeneity, respectively. A qualitative analysis was also performed using the QUADAS tool. RESULTS Eighteen studies qualified for the final analyses. Three physical examination tests (McMurray's, Apley's, and joint line tenderness) were examined in more than 7 studies and had enough data to consider meta-analysis. However, study results were heterogeneous. Pooled sensitivity and specificity were 70% and 71% for McMurray's, 60% and 70% for Apley's, and 63% and 77% for joint line tenderness. Large between-study differences could not be explained by prevalence, study quality, or how well an index test was described. CONCLUSIONS No single physical examination test appears to accurately diagnose a torn tibial meniscus and the value of history plus physical examination is unknown. Differences between studies in diagnostic performance remain unexplained, presumably due to local differences in the way the tests are defined, performed, and interpreted. We recommend a more standardized approach to performing and interpreting these tests and the development of a clinical prediction rule to aid clinicians in the diagnosis of a torn tibial meniscus.

Abstract
PURPOSE Five common tests were used to diagnose meniscal tears when used as a composite score. We evaluated how effectively the composite examination, when performed in the presence of an anterior cruciate ligament (ACL) injury or degenerative joint disease (DJD), determined the presence of meniscal tears. METHODS Data were collected prospectively on all patients at our clinic with a primary knee complaint. Independent variables included the presence or absence of the following: (1) a history of "catching" or "locking" as reported by the patient, (2) pain with forced hyperextension, (3) pain with maximum flexion, (4) pain or an audible click with McMurray's maneuver, and (5) joint line tenderness to palpation. Comprehensive patient demographic data were collected including ligamentous examinations and other intra-articular pathologies found at arthroscopy. Composite examination findings were correlated with the presence or absence of meniscal pathology. RESULTS We evaluated 635 knees in 576 patients for historical and physical findings. Of the knees, 209 underwent arthroscopic surgery and 426 did not. Chi(2) Analysis showed a significant relation between the number of positive diagnostic tests and the presence of meniscal tears (P = .001). Five positive findings on composite examination yielded a positive predictive value of 92.3%. Positive predictive values remained greater than 75% with composite scores of at least 3 in the absence of ACL and DJD pathologies. The presence of an ACL injury decreased the positive predictive value of 5 composite findings to 67%, whereas the presence of DJD increased predictability to 100%. CONCLUSIONS When all 5 symptoms and signs were positive, there was a 92.3% positive predictive value of finding a meniscal tear. Although positive predictive values decreased with a concomitant ACL injury and increased with DJD, there was a higher rate of false-positive findings (ACL) and false-negative findings (DJD). LEVEL OF EVIDENCE Level II, development of diagnostic criteria with consecutive patients and gold standard.

Abstract
PURPOSE The purpose of this retrospective study was to define the clinical and arthroscopic characteristics of anterior horn tears of the lateral meniscus. TYPE OF STUDY Case series. METHODS Fourteen patients with mean age of 20.2 years were enrolled in this institutional review board-approved study. All patients were soccer players with tears of the anterior horn of the lateral meniscus. All patients underwent physical examinations, magnetic resonance imaging (MRI), and arthroscopic treatment. RESULTS Common symptoms were a catching sensation in 10 patients (71.4%), pain at squatting in 9 patients (64.3%), and sense of giving way and effusion, each in 7 patients (50%). Five patients (35.7%) had lateral joint-line tenderness. McMurray's test was positive in 6 (42.9%) and tears were diagnosed by MRI in 13 (92.8%) patients. Arthroscopic examination showed multiple longitudinal tears in the avascular white zone of the meniscus in 7 patients (50%). CONCLUSIONS These data show that the McMurray test and joint-line tenderness had a low diagnostic value in diagnosing anterior horn tears of the lateral meniscus. MRI, however, had a high diagnostic value. Common arthroscopic findings included multiple longitudinal tears within the white zone of the anterior horn. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Clinical tests used for the detection of meniscal tears in the knee do not present acceptable diagnostic sensitivity and specificity values. Diagnostic accuracy is improved by arthroscopic evaluation or magnetic resonance imaging studies. The objective of this study was to evaluate the diagnostic accuracy of a new dynamic clinical examination test for the detection of meniscal tears. METHODS Two hundred and thirteen symptomatic patients with knee injuries who were examined clinically, had magnetic resonance imaging studies performed, and underwent arthroscopic surgery and 197 asymptomatic volunteers who were examined clinically and had magnetic resonance imaging studies done of their normal knees were included in this study. For clinical examination, the medial and lateral joint-line tenderness test, the McMurray test, the Apley compression and distraction test, the Thessaly test at 5 degrees of knee flexion, and the Thessaly test at 20 degrees of knee flexion were used. For all clinical tests, the sensitivity, specificity, false-positive, false-negative, and diagnostic accuracy rates were calculated and compared with the arthroscopic and magnetic resonance imaging data for the test subjects and the magnetic resonance imaging data for the control population. RESULTS The Thessaly test at 20 degrees of knee flexion had a high diagnostic accuracy rate of 94% in the detection of tears of the medial meniscus and 96% in the detection of tears of the lateral meniscus, and it had a low rate of false-positive and false-negative recordings. Other traditional clinical examination tests, with the exception of joint-line tenderness, which presented a diagnostic accuracy rate of 89% in the detection of lateral meniscal tears, showed inferior rates. CONCLUSIONS The Thessaly test at 20 degrees of knee flexion can be used effectively as a first-line clinical screening test for meniscal tears, reducing the need for and the cost of modern magnetic resonance imaging methods.
