- Although there have been many reports of good results when local anesthesia is used with knee arthroscopy, it is not used as a standard anesthetic. Concerns about local anesthesia include the fear of prolonged surgery, which could result in inadequate anesthesia, thus causing the patient unnecessary discomfort. The purpose of this study was to evaluate the risk of repeat arthroscopy and the patient satisfaction rate up to 6 months after knee arthroscopy under local anesthesia. In this prospective, randomized study, 400 patients scheduled for elective knee arthroscopy were allocated to one of three groups: local anesthesia (200 patients), spinal anesthesia (100 patients), or general anesthesia (100 patients). All enrolled patients were asked to complete a questionnaire 6 months after surgery and all of their medical records were reviewed. No repeat arthroscopies occurred in the spinal and general anesthesia groups and only three occurred in the local anesthesia group, a nonsignificant difference. In only one of these three cases was the clinical course altered by the repeat arthroscopy. There was no difference in the satisfaction rate between the three anesthesia groups. We conclude that the choice of anesthesia does not influence the frequency of repeat arthroscopy, satisfaction with the procedure, or recovery at 6 months after knee arthroscopy.

- Background: Little is known of injury patterns in track and field (athletics). Injury prevalence has been proposed as the most appropriate measure of the injury rate in sports where athletes are at risk for overuse problems. less thanbrgreater than less thanbrgreater thanPurpose: To ascertain 1-year retrospective and current prevalence of injury in elite track and field athletes to help plan injury prevention programs for this sport. less thanbrgreater than less thanbrgreater thanStudy Design: Descriptive epidemiology study. less thanbrgreater than less thanbrgreater thanMethods: Two hundred seventy-eight youth (16 years old) and adult athletes from an eligible study population of 321 athletes were included. less thanbrgreater than less thanbrgreater thanResults: The 1-year retrospective injury prevalence was 42.8% (95% confidence interval [CI], 36.9%-49.0%); the point prevalence was 35.4% (95% CI, 29.7%-41.4%). The diagnosis group displaying the highest injury prevalence was inflammation and pain in the gradual onset category (1-year prevalence, 20.9%; 95% CI, 16.2%-26.2%; and point prevalence, 23.2%; 95% CI, 18.4%-28.7%). A strong tendency for higher 1-year prevalence of 16.5% (95% CI, 12.2%-21.4%) than point prevalence of 8.5% (95% CI, 5.5%-12.5%) was recorded for sudden onset injuries in the diagnosis group sprain, strain, and rupture. The body region showing the highest injury prevalence was the knee and lower leg with 15.0% (95% CI, 11.0%-19.8%) 1-year prevalence and 13.7% (95% CI, 9.8%-18.3%) point prevalence, followed by the Achilles tendon, ankle, and foot/toe with 11.7% (95% CI, 8.2%-16.1%) 1-year prevalence and 11.4% (95% CI, 7.9%-15.8%) point prevalence. less thanbrgreater than less thanbrgreater thanConclusion: The injury prevalence is high among Swedish elite track and field athletes. Most of the injuries affect the lower extremities and are associated with a gradual onset. Although it is associated with a potential recall bias, the 1-year retrospective prevalence measure captured more sudden onset injuries than the point prevalence measure. Future prospective studies in track and field are needed to identify groups of athletes at increased risk.

- The use of sports massage is very common in the athletic community. However, only a few studies have shown any therapeutic effect of massage. Hypothesis Sports massage can improve the recovery after eccentric exercise. Study Design Prospective randomized clinical trial. Methods Sixteen subjects performed 300 maximal eccentric contractions of the quadriceps muscle bilaterally. Massage was given to 1 leg, whereas the other leg served as a control. Subjects were treated once daily for 3 days. Maximal strength was tested on a Kin-Com dynamometer, and functional tests were based on 1-leg long jumps. Pain was evaluated using a visual analog scale. Results There was a marked loss of strength and function of the quadriceps directly after exercise and on the third day after exercise. The massage treatment did not affect the level or duration of pain or the loss of strength or function following exercise. Conclusion Sports massage could not improve the recovery after eccentric exercise.

- Standardized assessment of sports injuries provides important epidemiological information and also directions for injury prevention. Purpose To analyze the frequency, characteristics, and causes of injuries incurred during the Summer Olympic Games 2008. Study Design Descriptive epidemiology study. Methods The chief physicians and/or chief medical officers of the national teams were asked to report daily all injuries newly incurred during the Olympic Games on a standardized injury report form. In addition, injuries were reported daily by the physicians at the medical stations at the different Olympic venues and at the polyclinic in the Olympic Village. Results Physicians and/or therapists of 92 national teams covering 88% of the 10 977 registered athletes took part in the study. In total, 1055 injuries were reported, resulting in an incidence of 96.1 injuries per 1000 registered athletes. Half of the injuries (49.6%) were expected to prevent the athlete from participating in competition or training. The most prevalent diagnoses were ankle sprains and thigh strains. The majority (72.5%) of injuries were incurred in competition. One third of the injuries were caused by contact with another athlete, followed by overuse (22%) and noncontact incidences (20%). Injuries were reported from all sports, but their incidence and characteristics varied substantially. In relation to the number of registered athletes, the risk of incurring an injury was highest in soccer, taekwondo, hockey, handball, weightlifting, and boxing (all ≥15% of the athletes) and lowest for sailing, canoeing/kayaking, rowing, synchronized swimming, diving, fencing, and swimming. Conclusion The data indicate that the injury surveillance system covered almost all of the participating athletes, and the results highlight areas of high risk for sport injury such as the in-competition period, the ankle and thigh, and specific sports. The identification of these factors should stimulate future research and subsequent policy change to prevent injury in elite athletes.

Anatomic Single- and Double-Bundle Anterior Cruciate Ligament Reconstruction, Part 2: Clinical Application of Surgical Technique.

- The anterior cruciate ligament has been and is of great interest to scientists and orthopaedic surgeons worldwide. Anterior cruciate ligament reconstruction was initially performed using an open approach. When the approach changed from open to arthroscopic reconstruction, a 2- and, later, 1-incision technique was applied. With time, researchers found that traditional arthroscopic single-bundle reconstruction did not fully restore rotational stability of the knee joint and a more anatomic approach to reconstruct the anterior cruciate ligament has been proposed. Anatomic anterior cruciate ligament reconstruction intends to replicate normal anatomy, restore normal kinematics, and protect long-term knee health. Although double-bundle anterior cruciate ligament reconstruction has been shown to result in better rotational stability in both biomechanical and clinical studies, it is vital to differentiate between anatomic and double-bundle anterior cruciate ligament reconstruction. The latter is merely a step closer to reproducing the native anatomy of the anterior cruciate ligament; however, it can still be done nonanatomically. To evaluate the potential benefits of reconstructing the anterior cruciate ligament in an anatomic fashion, accurate, precise, and reliable outcome measures are needed. These include, for example, T2 magnetic resonance imaging mapping of cartilage and quantification of graft healing on magnetic resonance imaging. Furthermore, there is a need for a consensus on which patient-reported outcome measures should be used to facilitate homogeneous reporting of outcomes.

- Nineteen consecutive patients undergoing anterior cruciate ligament reconstruction using the central third of the ipsilateral patellar tendon were included in the study. Serial magnetic resonance images revealed that the donor-site gap in the tendon decreased with time (mean follow-up, 26 months). The thickness was significantly increased compared with the intact contralateral patellar tendon, regardless of when the magnetic resonance imaging was performed. Ultrasonography showed the same findings at a mean follow-up of 26 months. Histologic evaluation of the repair tissue in the central part of the tendon, as well as the tissue in the peripheral part of the patellar tendon at the donor site, revealed a significant increase in cellularity and vascularity as compared with normal control tendons. Thus, 2 years after the harvesting procedure, the patellar tendon displayed significant radiographic and histologic abnormalities. On the basis of these findings, reharvest of the patellar tendon, at least up to 2 years after primary harvest, cannot be recommended.

- BACKGROUND: Cruciate ligament ruptures and shoulder dislocations are often caused by trauma, but predisposing intrinsic factors might also influence the risk. These injuries are more common in those with a previously injured sibling, an observation that might indicate a genetic predisposition. It is well known that polymorphisms in the collagen I gene are associated not only with osteoporosis and osteoporotic fracture risk, but also with osteoarthritis. HYPOTHESIS: Because collagen I is abundant in ligaments and tendons, the authors hypothesized that collagen I alpha1 Sp1 polymorphism also was related to the occurrence of cruciate ligament ruptures and shoulder dislocations. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: A total of 358 patients and 325 randomly selected population-based female controls were included in the study. Of the cases, 233 had a cruciate ligament rupture and 126 had had a shoulder dislocation. Age-adjusted odds ratios (ORs) with 95% confidence intervals (CIs) estimated by unconditional logistic regression were used as measures of association. RESULTS: Compared with the homozygous SS category, the heterozygous participants displayed a similar risk (OR, 1.06; 95% CI, 0.76-1.49), whereas the ss genotype was underrepresented in the injured population compared with the controls (OR, 0.15; 95% CI, 0.03-0.68). This latter estimate was similar for both cruciate ligament ruptures and shoulder dislocations, and was furthermore not modified by general joint laxity. CONCLUSION: The authors found a substantially decreased risk of these injuries associated with collagen type I alpha1 Sp1 polymorphism. The study might encourage other investigators to consider further research in the area of genes and soft tissue injuries.
