Prevention of ligament injuries to the knee.

Disruption of the ligamentous structures of the knee are commonly seen in competitive sports. Factors affecting the rate of injury include the sport, the participant, conditioning and technique, the level of competition, rules enforcement, the type of playing surface, and footwear. The role of prophylactic and functional bracing is controversial. Currently, prophylactic bracing has not been shown, conclusively, to be protective. Functional braces appear to have a capacity to provide some protective effect.

The effect of bracing on the collateral ligaments of the knee.

Disruption of the ligamentous structures of the knee is commonly seen in competitive sports. The role of prophylactic and functional bracing is controversial. Currently, prophylactic bracing has not been shown, conclusively, to be protective. Functional braces appear to have a capacity to provide some protective effect.

Pitfalls to avoid in diagnosing pain in the athlete.

Symptoms in the competitive athlete frequently are assumed to be related to overuse. A limited number of these patients will have orthopedic problems not related to their activity. This article outlines specific examples of bone tumors, infections, and metabolic causes of pain in the athlete.

Rupture of the distal tendon of the biceps brachii. Operative versus non-operative treatment.

We did Cybex testing of thirteen patients who had had a rupture of the distal tendon of the biceps brachii. The tests were performed fifteen months to six years after injury. The ten patients who had had a surgical repair through the two-incision technique showed a return to normal levels of strength and endurance with regard to both flexion of the elbow and supination of the forearm. The three patients who had had conservative treatment showed a remaining deficit in those parameters which was clinically evident in several activities, such as use of a screwdriver or baseball bat.

Current concepts in the diagnosis and treatment of musculotendinous injuries.

A strain, by definition, is a stretching or tearing of a musculotendinous unit. The degree of disability associated with this injury is dictated by the location and severity of the injury and the specific needs of the patient. A strain can be arbitrarily classified as first, second, or third degree. A first-degree strain consists of minimal stretching of the musculotendinous unit without permanent injury; a second-degree strain indicates partial tearing of the musculotendinous unit; and a third-degree strain indicates complete disruption of a portion of this unit. Swelling, bleeding, and localized discomfort accompany the injury which may produce temporary disability. Initial treatment following an acute strain should consist of the use of ice, immobilization of the musculotendinous unit, and subsequent rehabilitation. Depending on the degree of disability and the specific structure injured, surgery may be indicated. Rehabilitation to a normal state following the initial healing phase is required prior to return to athletic competition.

Prearthrotomy diagnostic evaluation of the knee: review of 100 cases diagnosed by arthrography and arthroscopy.

The results of 100 prearthrotomy evaluations of the knee including clinical examinations, arthrography, and arthroscopy were correlated with surgical findings. Arthroscopy was most accurate for meniscal lesions involving the central edge and anterior horn, anterior cruciate lesions, and chondromalacia. Arthrography was most accurate for midbody and peripheral tears. The combined accuracy of arthrography and arthroscopy in diagnosing all pathology within the 100 operated knees was 97%. Our results indicate that prearthrotomy arthroscopy and arthrography are complementary examinations and not mutually exclusive.

Organochlorine residues in harp seal (Phagophilus groenlandicus) tissues, Gulf of St. Lawrence, 1971, 1973.

Levels of p,p'-DDT, p,p'-TDE, p,p'-DDE, dieldrin, polychlorinated biphenyls (PCBs), and HCB were determined in certain tissues of 31 harp seals (P hagophilus groenlandicus) taken from the Gulf of St. Lawrence during 1971 and 1973. The seals ranged in age from less than two weeks to 18 years. Mean concentrations of PCBs and sigma DDT in the various tissues were about the same sigma DDT levels were 1.64--9.88 ppm in adult seal blubber and 1.08--3.73 ppm in seal pup blubber. Organochlorine levels in harp seal samples taken in 1973 were similar to those reported by other workers for samples collected in the Gulf of St. Lawrence during 1967-71.

Residues of atrazine and N-deethylated atrazine in water from five agricultural watersheds in Québec.

Atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) and N-deethylated atrazine (2-chloro-4-amino-6-isopropylamino-s-triazine) were monitored (1974 and 1975) in five rivers which drained agricultural areas in the Yamaska river basin of Québec. Water samples were collected frequently from April to December each year from sites near the outflow of each river. The water samples were extracted with benzene, chloroform, or ethyl acetate and the extracts were analyzed by gas chromatography using a Hall electrolytic conductivity detector and an alkali-flame detector. Atrazine and N-deethylated atrazine residues ranged in concentration from 0.01 to 26.6 microgram/L and less than 0.01 to 1.34 microgram/L, respectively, over the monitoring period. The highest levels of atrazine were observed in July each year and they coincided with the herbicide spraying season in this region and with occasional heavy rainfall events. Discharges (kg/yr) of atrazine from the five rivers were related to corn-growing area in each watershed. Losses of atrazine ranged from 0.1 to 2.9% of the atrazine that was estimated to have been applied in each watershed.
