BACKGROUND Osteoarthritis (OA) is a degenerative joint disease often present on the surface and edge of the joint and beneath cartilage forming new bone. Arthroscopy had been used for the treatment of knee OA. This study aimed to measure the expression of miR-22, miR-140, and BMP-2 in patients with OA before and after arthroscopy operation. MATERIAL AND METHODS The synovial fluid of 80 patients and 60 healthy volunteers were aspirated using a syringe before OA operation and again six months post-operation in patients with OA...

Patellofemoral pain syndrome (PFPS) is one of the most common diseases that cause pain in the knee joint. At present, there is no specific diagnostic measure. The diagnosis of patellofemoral pain syndrome may be considered when imaging is performed without cartilage, ligament and soft tissue injuries. The etiology includes abnormalities of the patellar motion caused by various anatomical abnormalities, such as abnormal patellar position, increased Q angle, and excessive valgus foot. Dysfunction of the lower extremity muscles such as the imbalance of the four biceps and the dysfunction of the gluteal muscles also play an important role in the development of patellofemoral pain syndrome...

Many hip arthroscopy patients experience significant pain in the immediate postoperative period. Although peripheral nerve blocks have demonstrated efficacy in alleviating some of this pain, they come with significant costs. Local infiltration analgesia (LIA) may be a significantly cheaper and efficacious treatment modality. Although LIA has been well studied in hip and knee arthroplasty, its efficacy in hip arthroscopy is unclear. The purpose of this retrospective study is to determine the efficacy of a single extracapsular injection of bupivacaine-epinephrine during hip arthroscopy in reducing the rate of elective postoperative femoral nerve blocks...

Septic arthritis after knee arthroscopy is an extremely rare condition. A rate of 0.15-0.84% cases of postoperative infection is estimated in several series. The arthroscopy procedure most frequently related with an infectious complication is anterior cruciate ligament (ACL) reconstruction, with a prevalence of 0.3-1.7% cases. Staphylococcus sp. is the pathogen most commonly cultured. We describe a case of septic arthritis after ACL reconstruction. We found no published case of septic arthritis caused by this microorganism after knee arthroscopy...

Objective The purpose of this study was to investigate the degree of standardized evaluation and reporting of cartilage lesion characteristics in high-impact clinical studies for symptomatic lesions of the knee. We hypothesized that there are significant inconsistencies in reporting these metrics across orthopedic literature. Design A total of 113 clinical studies on articular cartilage restoration of the knee were identified from 6 high-impact orthopedic journals between 2011 and 2016. Full-text review was used to evaluate sources for details on study methodology and reporting on the following variables: primary procedure, location, size, grade, and morphology of cartilage lesions...

Isolated posterior cruciate ligament (PCL) injuries are relatively rare and PCL injuries most commonly occur in the setting of multiligamentous knee injuries. PCL injuries can be treated with primary repair, which has the advantages of preserving the native tissue, maintaining proprioception, and minimal invasive surgery when compared with reconstruction surgery. Historically, primary repair of PCL injuries was performed in all tear types using an open approach, and, although the subjective outcomes were relatively good, patients often had residual laxity...

PURPOSE: To determine the association between glycemic control and infection following knee arthroscopy, and to determine the clinical utility of a threshold HbA1c level. METHODS: A national database identified patients who underwent knee arthroscopy from 2007 to 2016. Patients with concomitant open portions, more complex knee procedures, procedures performed for infection and patients with prior septic knee arthritis were excluded. Patients with an HbA1c level checked within 3 months of surgery were compared to control groups of nondiabetics and diabetics undergoing knee arthroscopy without a perioperative HbA1c...

Interposition of the transverse ligament of the knee between fragments of an intercondylar eminence fracture was diagnosed using magnetic resonance imaging (MRI) in a 11-year-old boy after a sports injury. The interposition was confirmed and corrected during arthroscopy. We report what we believe to be the first published case of isolated interposition of the transverse ligament in a minimally displaced fracture of the tibial eminence.

Introduction and Objectives: We previously found that women report more pain after knee arthroscopic procedures than men. It remains unclear whether this is due to different biochemical responses or nociceptive mechanisms. Methods: We analyzed acute pain-related inflammatory markers in a clinical model of patient self-reported pain immediately after knee surgery. To simultaneously measure 92 inflammatory biomarkers, we used the proximity extension assay with the Proseek Multiplex Inflammation I panel (Olink Bioscience, Uppsala, Sweden)...

BACKGROUND: Despite the availability of consistent guidelines recommending against arthroscopic treatment for people with symptomatic knee osteoarthritis, Australian data indicate continued use of this treatment modality. A paucity of easy to understand and reliable consumer information about knee arthroscopy may be one explanatory factor. The aim of this study was to determine whether consumer information about knee arthroscopy available in Australia is adequate to inform evidence-based decision-making for people with symptomatic osteoarthritis...

Arthroscopy is currently the gold standard for diagnosing intra-articular knee pathology. Magnetic resonance imaging (MRI) can be a clinical adjunct for diagnosis; however, it is not without its shortcomings. Although highly accurate, even advanced imaging misdiagnoses the condition in 1 in 14 patients with regard to anterior cruciate ligament pathology. Previous studies have indicated that MRI fails to identify meniscal pathology when one exists in 1 of every 10 cases, and diagnoses pathology when pathology truly does not exist in 1 of every 5 patients...

BACKGROUND AND OBJECTIVES: Perineural dexamethasone has been demonstrated to extend postsurgical analgesia after peripheral nerve blockade in adults. The mechanism of action of dexamethasone as a regional anesthetic adjuvant is unclear as intravenous dexamethasone has been shown to have similar analgesic efficacy as perineural dexamethasone. The efficacy of perineural dexamethasone has not been previously explored in the pediatric population. METHODS: After obtaining informed consent, children (aged 10-18 years) presenting for arthroscopic knee surgery with a femoral nerve block were randomized to 1 of 3 groups: ropivacaine 0...

This study aimed to evaluate the relationship between preoperative lateral meniscal extrusion (LME) and arthroscopic findings of lateral meniscus posterior root tear (LMPRT) in knees with anterior cruciate ligament (ACL) tear. Thirty-five knees that had LMPRTs with concomitant ACL tears on arthroscopy were evaluated. Patients were divided into two groups, partial and complete root tears, via arthroscopic findings at the time of ACL reconstruction. For comparison, we added two groups, using the same database; 20 normal knees (normal group) and 20 ACL-injured knees without LM injury (intact LM group)...

INTRODUCTION: We present the first retrospective study that compares two various autologous matrix-induced chondrogenesis (AMIC) surgical interventions to repair grade III-IV cartilage defects in the knee. Patients who underwent minimally invasive (arthroscopy) or open (mini-arthrotomy) AMIC were followed up to 2 years to investigate if minimally invasive AMIC is superior to open procedures. MATERIALS AND METHODS: Overall n = 50 patients with focal and contained grade III-IV articular cartilage defects in the knee joint were followed in a consecutive cohort study...
