Magnetic resonance imaging (MRI) provides an effective and noninvasive means by which to evaluate articular cartilage within the knee. Existing techniques can be utilized to detect and monitor longitudinal changes in cartilage status due to injury or progression of degenerative disease. Quantitative MRI (qMRI) techniques can provide a metric by which to evaluate the efficacy of cartilage repair techniques and offer insight into the composition of cartilage and cartilage repair tissue. In this review, we provide background on MR signal generation and decay, the utility of morphologic MRI assessment, and qMRI techniques for the biochemical assessment of cartilage (dGEMRIC, T2, T2*, T1ρ, sodium, gagCEST)...

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...

Ligamentous structures of the knee are numerous and complex, including the anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, ligaments of the posteromedial and posterolateral corners, and the anterolateral ligament. Clinical assessment after a knee injury is paramount and can direct both the clinician's choice of imaging study and the radiologist's interpretation. Imaging is crucial in that it provides additional information for diagnosis, management, and surgical planning...

The tendons of the knee play a critical role in the motion and stability of the knee. Knee pain, a common clinical complaint, can frequently be attributed to pathology of these structures. While the cornerstones of the radiological evaluation of the knee are radiography and magnetic resonance imaging, ultrasound can also play an important diagnostic role and can be useful for guided interventional procedures. Understanding the utility of each modality in the assessment for tendon pathology and a familiarity with the normal and abnormal imaging appearance of these structures are crucial for accurate diagnosis...

Our purpose was to evaluate if there is any association between requiring contralateral anterior cruciate ligament (ACL) reconstruction and various: (1) demographics, (2) patient characteristics, and (3) surgery-specific factors. A prospectively collected database at a single institution was queried to find all patients who underwent primary ACL reconstruction between 2012 and 2014. We identified 312 primary ACL reconstruction patients with a mean age of 24 years and a mean follow-up of 3 years (range, 2-5 years)...

FIBTEM parameters might predict the amount of postoperative hemorrhage following total knee arthroplasty (TKA), because fibrin polymerization and fibrinolysis have a central role in postoperative hemorrhage following TKA. This study retrospectively evaluated 54 patients who had undergone unilateral primary TKA. Laboratory coagulation parameters, including FIBTEM, were recorded before anesthesia induction and after admission to the postanesthetic care unit. The decrease in hemoglobin (Hb), amount of hemorrhage via closed suction drainage, fluid administration, and amount transfused were reviewed postoperatively...

As the use of disease modifying antirheumatic drugs have increased, it remains unclear whether or not this has affected the rates of total knee arthroplasty (TKA) in rheumatoid arthritis (RA) patients. Therefore, the purpose of this study was to evaluate the annual trends of RA patients who underwent TKA. Specifically, we evaluated: (1) the annual trends of TKAs due to RA in the United States population; and (2) the annual trends in the proportion of TKAs due to RA in the United States. The Nationwide Inpatient Sample was used to identify all patients who underwent TKA between 2002 and 2013 (n = 6,492,873)...

Few studies have compared outcomes between autografts versus hybrid grafts (combination of autograft and allograft) for anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to compare revision rate and patient-reported outcomes following primary ACLR with a hamstring autograft versus a preoperatively planned hybrid autograft-allograft. At a minimum 2-year follow-up, patients who had undergone primary ACLR with a double-stranded semitendinosus and gracilis hamstring autograft (A) or a planned hybrid (H) graft (single-strand semitendinosus with nonirradiated peroneus longus or tibialis posterior allograft) were contacted to fill out a survey containing the Knee Injury and Osteoarthritis Outcome Score (KOOS), Subjective International Knee Documentation Committee (IKDC) score, Single Assessment Numeric Evaluation (SANE), 12-Item Short-Form Health Survey (SF-12), and visual analog scale (VAS) for activity level prior to injury and at follow-up...

Previous studies suggest that complex regional pain syndrome (CRPS) occurs in up to 21% of patients following total knee arthroplasty (TKA). However, this diagnosis has a substantial impact on the patient's management if it is incorrect. We aimed to identify cases, using updated internationally accepted criteria, while investigating potential causes of misdiagnosis.We prospectively studied a consecutive series of 100 primary TKA patients. Each patient was assessed 6-week post-TKA. Pain levels were recorded with the presence of symptoms and signs of CRPS (Budapest Diagnostic Criteria) assessed in those with excessive pain...

Lower extremity joint arthroplasty procedures often require a large incision to have an adequate exposure, which subsequently leads to lengthy wounds that may contribute to long closure, anesthesia, and overall operative times. The recently introduced knotless barbed suture may provide better outcomes, faster closure time, and decreased material utilization. Therefore, the aim of this study was to review the impact of barbed sutures on: (1) wound-related complications; (2) closure and operative time; (3) patient outcomes (range of motion and Knee Society Scores [KSS]); and (4) effects on cosmesis and patients' satisfaction...

The discussion as to whether or not to use closed suction drainage (CSD) after total knee arthroplasty (TKA) is still ongoing. A multitude of surgical techniques makes comparison between studies difficult. The aim of the present study was to investigate the benefit of CSD versus nondrainage following primary TKA when operating after exsanguination (by means of a rubber Esmarch bandage) with a tourniquet and without any form of hemostasis. A prospective randomized trial was performed with a homogeneous sample of 36 patients with strict inclusion and exclusion criteria...

This article identifies the potential mechanisms of action for meniscal degeneration in response to joint inflammation and potential contributions of the meniscus to the development and progression of osteoarthritis (OA). It was hypothesized that interleukin-1β (IL-1β) stimulation of meniscal explants would result in significant increases in nitric oxide (NO), matrix metalloproteinase (MMP) production and activity, and relevant cytokine production compared with controls. Canine meniscal explants (4 mm) were cultured for 21 days with (IL-1) or without (negative control [NC]) 50 ng/mL rcIL-1β (n = 6/group)...

Demand for total hip (THA) and knee arthroplasties (TKA) is expected to rise sharply by 2030. Increasing demand in conjunction with financial pressure requires the use of cost-effective total joint arthroplasty (TJA) strategies. This study examined the effects that day of week and surgery location [academic (AH) versus orthopaedic-specific (OsH) hospital] have on length of stay (LOS) and cost for primary TJA patients in one multihospital university-based medical center. An Institutional Review Board-approved database of adult patients undergoing primary THA or TKA from June 2013 to December 2014 was constructed...

We asked whether there would be any difference between primary and revision modern cemented fixed hinge megaprosthesis of the distal femur in function and activity-related outcomes following treatment of a bone tumor. An identical custom-made fixed hinge cemented megaprosthesis with a hydroxyapatite collar was used in all cases. The main outcomes were joint-specific function, disease-specific activity, and health-related quality of life. Implant survival was also evaluated. Patients in the revision group performed slightly better than patients in the primary group on disease-specific (Toronto Extremity Salvage Score, p = 0...
