OBJECTIVES: This study aims to evaluate sonoelastographic properties of the distal femoral cartilage in patients with anterior cruciate ligament (ACL) reconstruction. PATIENTS AND METHODS: Demographic characteristics and operative data of 28 patients (27 males, 1 female; mean age 31.7±7.1 years; range 22 to 48 years) with unilateral ACL reconstruction were evaluated. Reconstruction was performed with patellar tendon graft in 22 patients (78.6%) and hamstring tendon graft in six patients (21...

It is important to assess the early degeneration of articular cartilage associated with osteoarthritis (OA) for early intervention and treatment planning. Previously, we have developed a high frequency ultrasound and water jet indentation method for the morphologic, acoustic and mechanical assessment of articular cartilage, using the enzymatic digestion as a model of osteoarthritic degeneration. No naturally degenerated articular cartilage has been tested with the developed method. In this study, we aimed to determine the usefulness of the developed method for detecting the natural degeneration of articular cartilage in a standard surgical model of OA in rabbits...

Recognizing subtle cartilage changes in the preclinical stage of osteoarthritis (OA) is essential for early diagnosis. To this end, the ability of the ultrasound signal intensity to detect macroscopically undetectable cartilage change was investigated. In this study, cartilage of rabbit OA model and human OA samples was examined by macroscopic evaluation, ultrasound signal intensity, histology with Mankin scores, and Fourier transform infrared imaging (FTIRI) analysis. Rabbit OA was induced by anterior cruciate ligament transection and evaluated at 1, 2, 4 and 12 weeks...

Incorporation of a tendon graft within the bone tunnel represents a challenging clinical problem. Successful anterior cruciate ligament (ACL) reconstruction requires solid healing of the tendon graft in the bone tunnel. Enhancement of graft healing to bone is important to facilitate early aggressive rehabilitation and a rapid return to pre-injury activity levels. No convenient, effective or inexpensive procedures exist to enhance tendon-bone (T-B) healing after surgery. Low-intensity pulsed ultrasound (LIPUS) improves local blood perfusion and angiogenesis, stimulates cartilage maturation, enhances differentiation and proliferation of osteoblasts, and motivates osteogenic differentiation of mesenchymal stem cells (MSCs), and therefore, appears to be a potential non-invasive tool for T-B healing in early stage of rehabilitation of ACL reconstruction...

Injuries of the knees are common. The Ottawa knee rule provides decisional support to determine whether radiographs are indicated or not. With the use of ultrasound it is possible to detect defects of the extensor ligaments and the anterior cruciate ligament. Furthermore, it is possible to detect indirect signs of an intra-articular fracture, e.g. lipohemarthrosis. In complex fractures, e.g. tibial plateau fractures, further diagnostic procedures with multislice computed tomography (CT) are needed for accurate classification and preoperative planning...

OBJECTIVE: The aim of the study was to investigate whether high frequency ultrasound technique, originally designed for arthroscopic use can be utilized to detect traumatic cartilage injuries. METHODS: A total of four intact osteochondral plugs were prepared from eight patellas for parallel comparison (total of 32 plugs). The plugs were injured by dropping an impactor on them from heights of 2.5 cm, 5.0 cm, 10.0 cm and 15.0 cm (corresponding to impact energies of 0...

Recent studies have shown a positive correlation between the degree of severity of OA and the number of apoptotic chondrocytes. The purpose of our study was to determine the effect of therapeutic ultrasound on apoptosis in articular cartilage of rabbits with knee osteoarthritis (KOA). Thirty 3-month New Zealand White rabbits were randomizingly divided into three groups, 10 in each group. Two groups underwent anterior cruciate ligament transaction in the right knee and another group left intact. Six weeks later, one group of the operated rabbits (OA-US) underwent ultrasound therapy (300 mW/cm(2), 1 MHz, 20% duty cycle, 10 min each day) for 2 weeks, while the other two groups (OA-Control and Normal Control) left untreated...

OBJECTIVE: To study the therapeutic effects that different physical factors may have on rabbits with osteoarthritis of the knee. METHODS: A total of 64 rabbits were randomised and organised into eight groups, eight of which were each assigned a different physical factor, in which the rabbits received one type of physical therapy: millimetre waves for 20 min, pulsed electromagnetic fields, millimetre waves for 40 min, ultrasound, low-level laser therapy or ultrashort wave diathermy...

RATIONALE AND OBJECTIVES: Osteoarthritis (OA) is a common disease, and early diagnosis is essential for preventing further cartilage destruction and decreasing severe complications. Ultrasound biomicroscopy (UBM) is sensitive for detecting minute lesions in tissue because of its higher resolution, but its B-mode characterization of the early stage of OA has not been widely studied. The aim of this study was to determine the usefulness of UBM for detecting the early stage of OA using a rabbit model of early OA...

In this study, the effect of low-intensity pulsed ultrasound (LIPUS) on cartilage was evaluated in a rat osteoarthritis (OA) model using serum biomarkers such as CTX-II (type II collagen degradation) and CPII (type II collagen synthesis) as well as histological criteria (Mankin score and immunohistochemical type II collagen staining). OA was surgically induced in the knee joint of rats by anterior cruciate/medial collateral ligament transection and medial meniscus resection (ACLT + MMx). Animals were divided into three groups: sham-operated group (Sham), ACLT + MMx group without LIPUS (-LIPUS), and ACLT + MMx group with LIPUS (+LIPUS; 30 mW/cm(2), 20 min/day for 28 days)...

Pain in the knee joint is one of the commonest complaints for which people seek an advice of different medical specialists. The aim of this study was to elucidate the cause of pain in patients with the alleged diagnosis of "osteoarthrosis" and to develop the relevant diagnostic algorithm. The study included 214patients aged from 35 to 85 years with a pain level of at least 40 mm by the visual analog scale (VAS). Results of physical and X-ray examination provided indications for further studies that were performed by ultrasonographic (40...

OBJECTIVE: To evaluate high frequency (40 MHz) B-mode ultrasound for the detection of osteoarthritis (OA) lesions of varying severity in an animal model of OA. DESIGN: Ultrasound biomicroscopy (UBM) was performed on the femoral articular surface of adult rabbits with unilateral transection of the anterior cruciate ligament at 4, 8 and 12 weeks post-surgery and on control rabbits. The articular cartilage was examined and graded macroscopically and histologically for OA lesions...

An arthroscopic technique for the use of mosaicplasty osteochondral grafting in the treatment of femoral condylar articular defects is described. During the procedure, small cylindrical grafts are harvested from the nonweightbearing periphery of the patellofemoral joint and implanted in mosaiclike fashion into the focal cartilage defect of the weightbearing condylar surface. This report describes the arthroscopic technique using newly designed instruments and the early results of 44 patients treated by this method...

REVIEW
P Renström
Increasing participation and training intensity in sports and physical activity has resulted in an increasing number of injuries as well as recognition of "new" injuries. Improved diagnostic techniques such as MRI, CT scan, scintigraphy and ultrasound have proven to be valuable in the diagnosis of especially soft tissue injuries. Surgery is today generally accepted as the treatment of choice for anterior cruciate ligament injuries in the active population. Arthroscopic reconstruction using the bone-patellar tendon-bone graft is considered to be the "gold standard"...
