Rupture of a popliteal cyst and dissection of its contents into the calf may produce pain, swelling, a positive Homan's sign and other findings closely resembling thrombophlebitis of the calf. The correct diagnosis is not often made, and the patient is subjected to needless long term anticoagulant therapy with its potential complications. To avoid this, it is essential that this possibility be kept in mind in all patients in whom the diagnosis of thrombophlebitis is considered. The history of preexisting arthritis of the knee, joint effusion and popliteal cyst are strongly suggestive of a ruptured popliteal cyst. This diagnosis can be verified by arthrography, ultrasonography, computed tomography and radionuclide scanning. Arthrography is preferred because it reveals superior anatomic detail thereby making differentiation between an encapsulated calf cyst, with smooth walls, and rupture, with irregular feathery margins, possible. Three illustrative cases are presented and the literature is reviewed.

One hundred patients with recently acquired, externally visible mandibular deformity and no history of previous extraarticular mandible fracture were selected for retrospective analysis. All had been investigated clinically and with radiography, tomography, and high-field surface-coil MR imaging to determine the presence or absence and extent of temporomandibular joint degeneration. Temporomandibular joint degeneration was found in either one or both joints of each patient studied. Chin deviation was always toward the smaller mandibular condyle or more diseased joint, and many patients either complained of or exhibited malocclusion, often manifested by unstable or fluctuating occlusion disturbances. Three radiologically distinct forms of degenerative vs adaptive osteocartilaginous processes--(1) osteoarthritis, (2) avascular necrosis, and (3) regressive remodeling--involving the mandibular condyle and temporal bone were identified in joints most often exhibiting meniscus derangement. Osteoarthritis and avascular necrosis of the mandibular condyle and temporal bone were generally associated with pain, mechanical joint symptoms, and occlusion disturbances. Regressive remodeling was less frequently associated with occlusion disturbances, despite remodeling of the facial skeleton, and appears to result from regional osteoporosis. Forty patients (52 joints) underwent open arthroplasty procedures, including either meniscectomy or microsurgical meniscus repair, at which time major radiologic diagnoses were confirmed. Surgical and pathologic findings included meniscus displacement, disk degeneration, synovitis, joint effusion, articular cartilage erosion, cartilage healing/fibrosis, cartilage hypertrophy, osseous sclerosis, osteophyte formation, osteochondritis dissecans, localized or extensive avascular necrosis, and decreased mandibular condyle mass and vertical dimension. We conclude that temporomandibular joint degeneration is the principal cause of both acquired facial skeleton remodeling and unstable occlusion in patients with intact dentition and without previous mandible fracture.

Diagnostic criteria for bacterial suppurative arthritis include the demonstration of an inflammatory exudate by aspiration of synovial fluid and the isolation of bacteria from cultures of synovial fluid and/or blood. Clinical manifestations include joint effusion, swelling, tenderness, and pain, with or without redness of the overlying skin. Management consists of antimicrobial therapy, measures designed to relieve symptoms, surgical drainage of infected fluid, and physical therapy. Studies of new anti-infective therapy should be limited to cases of bacterial origin. Prospective, randomized, double-blind, or evaluator-blinded, active-control comparative clinical trials should be performed. Clinical response is characterized as success (cure), failure, or indeterminate outcome. The most common successful microbiological outcome is presumptive eradication. Follow-up should continue for 1 year before the final assessment.

Within the framework of an observational study carried out on a national basis and involving some 4,000 patients, a total of 1,156 patients with activated arthrosis were treated with oral ibuprofen and observed over a period of three weeks. It was found that, at a dose of 600 mg tid, ibuprofen led to significant remission rates in terms of the symptoms pain at rest, pain on movement, tenderness, restriction of movement, swelling, joint effusion, and morning stiffness. After the third week of treatment, these rates reached 90%. In the first week, rapid onset of action within the first 30 minutes was noted in about 50%, which increased in the third week to 65%. Since at the same time the tolerability of ibuprofen was also found to be good--4% side effects--it can be recommended also for long-term use in this indication.

The vacuum phenomenon was visualized in 20 of 100 scapulohumeral joints with osteochondritic lesions in 65 dogs. The phenomenon was associated with the finding of a cartilage flap, lack of joint effusion, and clinical signs of pain and lameness. The vacuum phenomenon was not observed on radiography of 30 clinically normal contralateral joints, and it could not be induced in 36 clinically normal scapulohumeral joints radiographed under stressed extension.

Thirty-five of 50 patients with different hip joint disease had sonographic evidence of joint effusion. Arthrocentesis confirmed effusions in 30 of these 35 patients. Thirty-two of the 35 patients had nocturnal pain. Both nocturnal pain and sonographic evidence of effusion decreased after aspiration (15 patients) and aspiration and injection of corticosteroids (15 patients). In a further group of 61 patients who subsequently had Charnley arthroplasties, 35 had positive sonograms before operation. Of these, 25 had effusions confirmed at operation, the remaining 10 having synovitis and capsule thickening. Again a correlation was found with nocturnal pain. The sensitivity of sonography in detecting hip joint effusion was 92% with a specificity of 70%. Nocturnal pain had a lower sensitivity, 85%, but higher specificity, 94%.

Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone that rarely exceeds 1.5 cm in greatest dimension. The lesion is most commonly located in the cortex of long bones where it is associated with dense, fusiform, reactive sclerosis. Less often, it may be cancellous, where reactive osteosclerosis is usually less intense and may be distant from the lesion. Cancellous lesions are frequently intraarticular (most often in the hip) and may be associated with synovitis and joint effusion. Rarely, osteoid osteomas occur in a subperiosteal location. Patients are usually young, and there is a strong male predominance. Pain is the most common symptom. Radiographs of patients with cortical osteoid osteoma are often diagnostic. Intraarticular lesions, however, may be subtle, and scintigraphy may be required to locate the lesion for subsequent computed tomography (CT). CT is useful to identify and precisely locate the lesion and to provide guidance for percutaneous localization or treatment.

There are several common findings and contradictions noted in the research related to thigh muscle reflex inhibition and sequelae that occur with knee joint injury. Reflex inhibition may be measured directly by electromyography, or the sequelae of reflex inhibition may be measured, as commonly occurs in the clinic setting. Electromyography is useful in determining the causes of reflex inhibition. The most frequently cited causes of thigh muscle reflex inhibition in knee injury are pain, joint effusion and knee immobilisation. The other measurement methods described vary from thigh circumference measurement to muscle biopsy. These methods are useful in determining the magnitude and duration of the deleterious sequelae that affect the thigh muscles after reflex inhibition. Finally, there is selectivity of reflex inhibition after knee joint injury: the quadriceps versus the hamstrings, the different components of the quadriceps muscle group, and the different types of muscle fibres. In light of these findings, several suggestions have been offered for prevention of reflex inhibition and for techniques that can be applied to rehabilitate the most affected muscle group: the quadriceps femoris. Techniques used to prevent or limit the amount of reflex inhibition include cryotherapy, transcutaneous electrical nerve stimulation, iontophoresis, phonophoresis, joint mobilisation, rest and proper positioning of the knee in rest and exercise. Electromyostimulation, electromyographic biofeedback and traditional exercise training are 3 methods used to rehabilitate the quadriceps.
