The CO2 laser in arthroscopy: potential problems and solutions.

The CO2 laser is the most commonly used laser in arthroscopic surgery. This device offers enhanced precision in both cutting and ablation, as well as improved accessibility of difficult to reach structures. However, the use of energy rather than mechanical devices, the lack of tactile feedback, and the necessary use of a gaseous environment can result in problems not encountered in conventional arthroscopic surgery. This article presents these problems and suggests solutions.

Orthopedic preparticipation screening examination.

The primary care physician is often called upon to perform a medical examination before the patient may participate in athletic activities. The examination should identify congenital and acquired musculoskeletal problems and the residuals of previous musculoskeletal injuries. This article and its illustrations show the steps of an orthopedic preparticipation screening examination and indicate how some problems may be identified.

A review of the use of prophylactic knee braces in football.

A review of nine studies of prophylactic knee braces worn by players in American tackle football lends some support for the use of double-hinged braces at the high-school level. Evidence for their use at the college level seems less persuasive. Caution should be exercised in interpreting these studies owing to the probable presence of bias and confounding variables and to difficulty in generalizing results beyond the study populations. The two studies that assigned braces randomly found lower injury rates for knees and knee ligaments among high-school and high-school size players. Conversely, a large, multiteam collegiate study found a significantly higher rate of knee injuries among brace users, a difference that remained when controlled for position, skill, and previous injury.

Clinical significance and evaluation of prophylactic knee brace studies in football.

A review of nine studies of prophylactic knee braces in American tackle football found some support for the use of double-hinge braces in high school but little support for their use at the collegiate level. Problems with bias and confounding make it necessary that caution be exercised in the interpretation of the results of these studies, however,. To which groups these results might apply must also be considered. The two studies that assigned braces randomly found lower injury rates among high school and high-school-sized players for knee injuries and knee ligament injuries. Conversely a large, multiteam collegiate study found a significantly higher rate of knee injuries among brace users, a difference that remained when controlled for position, skill, and previous injury.

The epidemiology of foot and ankle injuries in sports.

A 6 1/2-year review of 16,754 injuries seen in a multispecialty sports medicine clinic found that 25 per cent of the 12,681 injuries in the top 19 sports occurred at the ankle and foot. The percentages of foot and ankle injuries varied substantially from sport to sport, as did the proportion of sprains versus overuse injuries at each location. An appreciation of the patterns and numbers of injuries presenting can be helpful in patient management and can aid the planning of both clinical investigations and educational programs.

Prophylactic knee bracing.

Six studies to determine the effectiveness of prophylactic knee braces in preventing medial collateral ligament (MCL) injury in football are compared. Criteria useful in evaluating studies are discussed, such as the probability of confounding factors, bias in selecting cases and controls, and variations in defining injury and exposure. Cost, as well as some ethical issues associated with mandated use are discussed. While four of these studies found a reduction in MCL injuries associated with using a brace, two of them reported increases. No consensus arises from these studies, conflicting results as well as methodological problems in some make it impossible to state with assurance the role of prophylactic knee bracing in football at this time.

Sports medicine.

A product of the recent physical fitness boom has been an increased demand for better care of sport and recreational injuries. This article gives an overview of the care available for such injuries. In addition, it also cautions against the kind of care that will only produce noncompliance in the pediatric patient.

Girls' sports injuries in high school athletics.

Because of appreciable increases in the number of participants, injuries resulting from girls' interscholastic athletic activities have become a concern for school administrators and medical care providers. Four girls' high school athletic programs were prospectively studied for two years. Specially trained athletic trainers placed at each school examined each injured athlete and collected epidemiologic data. The 870 participant-seasons in nine sports resulted in 192 injuries. Three times more injuries occurred in practices than in competitive events. Although more than one third required a physician's services, the majority (59%) had returned to full athletic activity within a week of injury. Strains and sprains accounted for nearly two thirds of the injuries. Generally, the type and frequency of injuries were comparable with those seen in noncontact boys' interscholastic sports.

Injuries in high school sports.

A two-year study was made of injuries received in high school sports. Athletic trainers were placed in four high schools to conduct the investigation. Injuries occurred in women's sports at a rate of 22 per 100 participants; men's injuries occurred at a rate of 39 per 100 participants. Football and wrestling accounted for the highest injury rates; tennis and swimming accounted for the lowest rates for both sexes.

Parameters of injury reporting in skiing.

An injury survey of 505 skiers from the 1971-72 and 5,459 skiers from thh 1972-73 season collected 601 time loss injries for a rate of 9.31000 skier days. Forty percent of these injuries were reported to a ski patrol and almost 60 to physicians. Fractures and lacerations were reported to the patrol more frequently than other injury types, bruises and strains less commonly. Injuries not reported to patrols and physicians were primarily bruises, sprains and strains. Although fractures were almost invariably reported to physicians, one in four was not seen by the ski patrol. Patrol-only or physician only reported injuries thus do not represent the full spectrum of time loss skiing injuries.

Healing of electrosurgical and scalpel wounds in rabbits.

Skin wounds in rabbits were tested after healing periods of up to three weeks to determine if scalpel wounds differed from those made electrosurgically. Tensile tests showed that the electrosurgical wounds were initially stronger, but at four days there was no difference. Thereafter the scalpel wounds were stronger and their healing progressed much faster. Histological preparations showed more extensive inflammation and necrosis in the electrosurgical wounds.
