Arthroscopy - Orthoinfo - AAOS 6/10/12 3:40 PM
Arthroscopy - OrthoInfo - AAOS 6/10/12 3:40 PM Copyright 2010 American Academy of Orthopaedic Surgeons Arthroscopy Arthroscopy is a surgical procedure orthopaedic surgeons use to visualize, diagnose, and treat problems inside a joint. The word arthroscopy comes from two Greek words, "arthro" (joint) and "skopein" (to look). The term literally means "to look within the joint." In an arthroscopic examination, an orthopaedic surgeon makes a small incision in the patient's skin and then inserts pencil-sized instruments that contain a small lens and lighting system to magnify and illuminate the structures inside the joint. Light is transmitted through fiber optics to the end of the arthroscope that is inserted into the joint. By attaching the arthroscope to a miniature television camera, the surgeon is able to see the interior of the joint through this very small incision rather than a large incision needed for surgery. The television camera attached to the arthroscope displays the image of the joint on a television screen, allowing the surgeon to look, for example, throughout the knee. This lets the surgeon see the cartilage, ligaments, and under the kneecap. The surgeon can determine the amount or type of injury and then repair Here are parts of the shoulder joint as or correct the problem, if it is necessary. seen trhough an arthroscope: the rotator cuff (RC), the head fo the humerus Why is arthroscopy necessary? (HH), and the biceps tendon (B). Diagnosing joint injuries and disease begins with a thorough medical history, physical examination, and usually X-rays. Additional tests such as magnetic resonance imaging (MRI) or computed tomography (CT) also scan may be needed. -

The Benefit of Arthroscopy for Symptomatic Total Knee Arthroplasty
CORE Metadata, citation and similar papers at core.ac.uk Provided by Elsevier - Publisher Connector Arthroscopy for symptomatic total knee arthroplasty THE BENEFIT OF ARTHROSCOPY FOR SYMPTOMATIC TOTAL KNEE ARTHROPLASTY Hsiu-Peng Teng, Yi-Jiun Chou, Li-Chun Lin, and Chi-Yin Wong Department of Orthopedic Surgery, Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan. Thirty-one knees with symptomatic total knee arthroplasty were diagnosed and treated arthroscopically. There were 18 knees with soft tissue impingement and 13 knees without. There were 16 knees with painful arthroplasty and range of motion (ROM) greater than 90°. Hypertrophied synovitis with or without impingement was more easily found by arthroscopy in this group than in the other 15 knees with the chief complaint of limited ROM, where more remarkable fibrotic tissue with intra-articular adhesion was found. Overall, the average improvement in ROM was 43.1° immediately after arthroscopy, and 20° at the final follow-up. Symptoms improved in 90.3% of patients, and 58.1% were satisfied with the outcome of their surgery. Arthroscopy is helpful for intra-articular diagnosis, obtaining a specimen for histopatho- logic analysis, culture for subclinical infection, and better improvement in ROM. In our experience, arthros- copy for symptomatic knee arthroplasty is reliable, safe and effective.

Validation of a Clinical Prediction Rule for the Differentiation Between Septic Arthritis and Transient Synovitis of the Hip in Children by MININDER S
COPYRIGHT © 2004 BY THE JOURNAL OF BONE AND JOINT SURGERY, INCORPORATED Validation of a Clinical Prediction Rule for the Differentiation Between Septic Arthritis and Transient Synovitis of the Hip in Children BY MININDER S. KOCHER, MD, MPH, RAHUL MANDIGA, BS, DAVID ZURAKOWSKI, PHD, CAROL BARNEWOLT, MD, AND JAMES R. KASSER, MD Investigation performed at the Departments of Orthopaedic Surgery, Biostatistics, and Radiology, Children’s Hospital, Boston, Massachusetts Background: The differentiation between septic arthritis and transient synovitis of the hip in children can be difficult. The purpose of the present study was to validate a previously published clinical prediction rule for this differentiation in a new patient population. Methods: We prospectively studied children who presented to a major children’s hospital between 1997 and 2002 with an acutely irritable hip. As in the previous study, diagnoses of septic arthritis (fifty-one patients) and transient synovitis (103 patients) were operationally defined on the basis of the white blood-cell count in the joint fluid, the re- sults of cultures of joint fluid and blood, and the clinical course. Univariate analysis and multiple logistic regression were used to compare the two groups. The predicted probability of septic arthritis of the hip from the prediction rule was compared with actual distributions in the current patient population. The area under the receiver operating char- acteristic curve was determined. Results: The same four independent predictors of septic arthritis of the hip (a history of fever, non-weight-bearing, an erythrocyte sedimentation rate of 40 mm/hr, and a serum white blood-cell count of >12,000 cells/mm3 (>12.0 × 109/L)) were identified in the current patient population. -
Procedure Name: Knee Arthroscopy Brief Description of Procedure
Procedure Name: Knee Arthroscopy Brief Description of Procedure: Arthroscopic surgery is a common orthopedic procedure that is used to diagnose and treat problems in joints. Greek words: ‘arthro,’ meaning “joint” and ‘scope,’ meaning, “look.” When arthroscopy is per- formed, a telescope with a camera is inserted into the joint through a small incision. The camera is attached to a light source and shows a picture of the inside of the joint on a monitor. One or more incisions may be made to treat the underlying problem. This procedure can be used to diagnose a joint problem, perform surgery that repairs a joint problem, remove a loose or foreign body, or monitor a dis- ease or the effectiveness of a treatment. Arthroscopy is commonly performed on the knee, shoulder, and ankle. It also can be done on the hip, elbow, and wrist. Describe anesthesia type that typically is given: General Anesthesia is usually used for this surgery. See Anesthesia Section. What patients that smoke can expect when having surgery: After surgery your anesthesia specialist will check your breathing and lung sounds to determine if a breathing treatment is needed. Smoking increases airway irritation, which leads to wheezing and coughing. Further breathing treatments and medications are sometimes needed. Average length of surgery time: 45 minutes-1 hour Average length in immediate recovery: 30 minutes Average length for time of discharge: Expect to be here an average of one hour after surgery. During this time you may experience some discomfort. Medication can be given to make pain bearable. When can you go back to work: Depending on your occupation you and your doctor will discuss when you may return to work. -

Procedure Coding in ICD-9-CM and ICD- 10-PCS
Procedure Coding in ICD-9-CM and ICD- 10-PCS ICD-9-CM Volume 3 Procedures are classified in volume 3 of ICD-9-CM, and this section includes both an Alphabetic Index and a Tabular List. This volume follows the same format, organization and conventions as the classification of diseases in volumes 1 and 2. ICD-10-PCS ICD-10-PCS will replace volume 3 of ICD-9-CM. Unlike ICD-10-CM for diagnoses, which is similar in structure and format as the ICD-9-CM volumes 1 and 2, ICD-10-PCS is a completely different system. ICD-10-PCS has a multiaxial seven-character alphanumeric code structure providing unique codes for procedures. The table below gives a brief side-by-side comparison of ICD-9-CM and ICD-10-PCS. ICD-9-CM Volume3 ICD-10-PCS Follows ICD structure (designed for diagnosis Designed and developed to meet healthcare coding) needs for a procedure code system Codes available as a fixed or finite set in list form Codes constructed from flexible code components (values) using tables Codes are numeric Codes are alphanumeric Codes are 3-4 digits long All codes are seven characters long ICD-9-CM and ICD-10-PCS are used to code only hospital inpatient procedures. Hospital outpatient departments, other ambulatory facilities, and physician practices are required to use CPT and HCPCS to report procedures. ICD-9-CM Conventions in Volume 3 Code Also In volume 3, the phrase “code also” is a reminder to code additional procedures only when they have actually been performed. -

Ankle and Pantalar Arthrodesis
ANKLE AND PANTALAR ARTHRODESIS George E. Quill, Jr., M.D. In: Foot and Ankle Disorders Edited by Mark S. Myerson, M.D. Since reports in the late 19th Century, arthrodesis has been a successful accepted treatment method for painful disorders of the ankle, subtalar, and transverse tarsal joints. While the title of this chapter involves arthrodesis - the intentional fusion of a joint - as a form of reconstruction, this chapter will address not only surgical technique, but nonoperative methods of care as well. We will address the pathophysiology leading to ankle and hindfoot disability, succinctly review the existing literature on the topic of hindfoot and ankle arthrodesis, highlight the pathomechanics involved, and spend considerable time on establishing the diagnosis, indications, and preoperative planning when surgery is indicated. We also will discuss the rehabilitation of the postoperative patient, as well as the management of complications that may arise after ankle and pantalar arthrodesis. There are more than thirty different viable techniques that have been described in order to achieve successful ankle and hindfoot arthrodesis. It is not the purpose of this chapter to serve as compendium of all the techniques ever described. The author will, rather, attempt to distill into a useful amount of clinically applicable material this vast body of information that the literature and clinical experience provide. Ankle arthrodesis is defined as surgical fusion of the tibia to the talus. Surgical fusion of the ankle (tibiotalar) and subtalar (talocalcaneal) joints at the same operative sitting is termed tibiotalocalcaneal arthrodesis. Fusion of the talus to all the bones articulating with it (distal tibia, calcaneus, navicular, and cuboid) is termed pantalar arthrodesis. -

Barrett Copyright by Bradley Bernard Nelson 2017 All Rights Reserved ABSTRACT INVESTIGATION OF CATIONIC CONTRAST-ENHANCED COMPUTED TOMOGRAPHY FOR THE EVALUATION OF EQUINE ARTICULAR CARTILAGE Osteoarthritis and articular cartilage injury are substantial problems in horses causing joint pain, lameness and decreased athleticism resonant of the afflictions that occur in humans. This debilitating joint disease causes progressive articular cartilage degeneration and coupled with a poor capacity to heal necessitates that articular cartilage injury is detected early before irreparable damage ensues. The use of diagnostic imaging is critical to identify and characterize articular cartilage injury, though currently available methods are unable to identify these early degenerative changes. Cationic contrast-enhanced computed tomography (CECT) uses a cationic contrast media (CA4+) to detect the early molecular changes that occur in the extracellular matrix. Glycosaminoglycans (GAGs) within the extracellular matrix are important for the providing the compressive stiffness of articular cartilage and their degradation is an early event in the development of osteoarthritis. Cationic CECT imaging capitalizes on the electrostatic attraction between CA4+ and GAGs; exposing the proportional relationship between the amount of GAGs present within and the amount of CA4+ that diffuses into the tissue. The amount of CA4+ that resides in the tissue is then quantified through CECT imaging and estimates tissue integrity through nondestructive assessment.
