TL;DR: A prospective arthroscopic study of 106 skeletally mature male sportsmen who presented with an acute haemarthrosis of the knee due to sporting activities and found no age-related trend in the pattern of ACL injuries.
Abstract: We made a prospective arthroscopic study of 106 skeletally mature male sportsmen with an average age of 28.35 years (16.8 to 44) who presented with an acute haemarthrosis of the knee due to sporting activities. We excluded those with patellar dislocations, radiographic bone injuries, extra-articular ligamentous lesions or a previous injury to the same joint. The anterior cruciate ligament (ACL) was intact in 35 patients, partially disrupted in 28 and completely ruptured in 43. In the patients with an ACL lesion, associated injuries included meniscal tears (17 patients), cartilaginous loose bodies (6), and minimal osteochondral fractures of the patella (2), the tibial plateau (3) or the femoral condyle (9). We found no age-related trend in the pattern of ACL injuries. Isolated injuries included one small osteochondral fracture of the patella, and one partial and one total disruption of the posterior cruciate ligament. Three patients had cartilaginous loose bodies, and no injury was detected in five. Acute traumatic haemarthrosis indicates a serious ligament injury until proved otherwise, and arthroscopy is needed to complement careful history and clinical examination. All cases with a tense effusion developing within 12 hours of injury should have an aspiration. If haemarthrosis is confirmed, urgent admission and arthroscopy are indicated.

TL;DR: Most injuries in elite young athletes are minor, their prevalence is low and, at least in the short to medium term, do not constitute a significant health problem.
Abstract: A group of 453 elite young athletes (231 boys, 222 girls) in five two year age groups from 8-16 years of age was followed up for two years in order to identify self reported injuries over that period. Four sports were studied, namely football (soccer), gymnastics, tennis, and swimming. The injury rate was low with just over half the children suffering one or more injuries per year, with the majority of those injured sustaining one injury only. Over the two year period of intensive sporting activity this amounted to less than one injury per 1000 hours of training. The highest risk of injuries was in football (67%) and the lowest in swimming (37%). Most injuries (70%) were acute and of a minor nature, although overuse injuries did require longer periods off training and competition than acute injuries (20 v 13 days). Footballers appeared to sustain more significant injuries than other sports as judged by the time required to resume training and/or competition (16 days after acute and 57 after overuse). No significant associations were found between injury rate, injury severity, sex, and pubertal status with the single exception of female gymnasts in whom more injuries occurred in the latter stages of puberty. Only four of the 453 athletes reported injury as a reason for retiring from their chosen sports. Most injuries in elite young athletes are minor, their prevalence is low and, at least in the short to medium term, do not constitute a significant health problem.

TL;DR: In this study, 400 clinically anterior cruciate ligament (ACL) deficient knees were arthroscoped and studied prospectively in the period January 1986 to April 1992, and an ACL tear was always confirmed, and 41 per cent of these patients did not have an associated meniscal tear.
Abstract: In this study, 400 clinically anterior cruciate ligament (ACL) deficient knees were arthroscoped and studied prospectively in the period January 1986 to April 1992. An ACL tear was always confirmed, and 41 per cent of these patients did not have an associated meniscal tear. In 30.25 per cent the lateral meniscus was torn; in 21.25 per cent the ACL tear was associated with a medial meniscus tear, and in the remaining 7 per cent both menisci were torn. The most frequently associated meniscal injury was the bucket handle tear of the medial meniscus (9 per cent), followed by the posterior horn tear of the lateral meniscus, which showed the same frequency as the ragged (or degenerated) tear of the lateral meniscus (6 per cent). The horizontal tear of the posterior part of the lateral meniscus showed a prevalence of 4.3 per cent. This picture is probably dependent on a secondary referral nature of the centre surveyed, in which the average time between injury and arthroscopy was 23.3 months.

TL;DR: It is believed that it is justified not to use a tourniquet in the operative treatment of simple, isolated fibular fractures because of the lower prevalence of postoperative complications and the shorter time to recovery for the patients in Group 2.
Abstract: A prospective, randomized trial was undertaken to determine the rate of complications after the use of a tourniquet during open reduction and internal fixation of simple, closed fractures of the distal part of the fibula. Forty patients were operated on with use of a tourniquet (Group 1) and forty patients, without use of a tourniquet (Group 2). The average duration of the operation was significantly different between the two groups (41 +/- 9 minutes for Group 1 compared with 53 +/- 12 minutes for Group 2 [p = 0.026]). There were more complications in the patients in Group 1, two of whom had an isolated deep-vein thrombosis of the calf. The wound was possibly infected in eleven patients (seven in Group 1 and four in Group 2 [p < 0.05]) and frankly infected in three patients, all in Group 1 (p < 0.05). The plaster-of-Paris cast needed to be changed in three patients from Group 1. The patients in Group 1 returned to work an average of one week later than those in Group 2. The mean duration of follow-up was eighteen months (range, nine to thirty-two months). Given the lower prevalence of postoperative complications and the shorter time to recovery for the patients in Group 2, we believe that it is justified not to use a tourniquet in the operative treatment of simple, isolated fibular fractures.

TL;DR: A review of the literature shows that an isolated ganglion arising from the anterior cruciate ligament is exceedingly rare, with only three such ganglia having been previously reported.
Abstract: We report three athletes with symptomatic isolated ganglion of the anterior cruciate ligament. The symptoms consisted of anteromedial knee pain, worse when changing direction while running, and on squatting. All gave a history of repeated minor knee trauma without a single episode of serious injury. At day-case arthroscopy, a unilobulated cystic mass arising from a clinically and arthroscopically intact anterior cruciate ligament was noted and removed in each case. No further intra- or extra-articular knee lesion was seen. Histology revealed a cystic ganglion in each case. With early physiotherapy, the patients could start gentle training 3 wk after arthroscopy, and, at 6-month review, were fully asymptomatic. A review of the literature shows that an isolated ganglion arising from the anterior cruciate ligament is exceedingly rare, with only three such ganglia having been previously reported.

TL;DR: Both aerobic and anaerobic exercise variables are seriously affected by post-viral fatigue syndrome, and one year may not be sufficient to fully recover.
Abstract: Maximal oxygen uptake, anaerobic threshold (AT), isometric strength of the elbow flexor and knee extensor muscles, isometric strength endurance exhaustion time (prolonged contraction at 66% of maximal isometric strength), uphill sprinting exhaustion time were longitudinally studied in eight varsity endurance runners with post-viral fatigue syndrome (PVFS). Prolonged impairment of exercise performance is evident during the course of PVFS. Although maximal oxygen uptake (VO2max) had returned to pre-infection values 13 months after the viral illness (4.160 vs 4.0 L.min-1), AT was still significantly reduced [52 ml.kg-1.min-1, 18.6 km.hr-1, 176 bpm, and 82% of VO2max vs. 49.1 ml.kg-1.min-1 (p < 0.05), 175 bpm (NS), 17.2 km.hr-1 (p < 0.01) and 79% of VO2max (NS)]. Maximal isometric contraction strength of the upper limb remained constant (282 N vs. 274 N), while knee extensor muscles strength decreased significantly (730 N vs. 701 N, p < 0.05). Strength endurance was still significantly reduced by the end of the study (arm average pre-infection: 46.2 sec; end of study: 29.3 sec, p < 0.001; leg average pre-infection: 66.4 sec; end of study: 49.1 sec, p < 0.01). Up hill sprinting time was similarly reduced by the end of the study period (29.3 sec vs. 16.2 sec, p < 0.01). Both aerobic and anaerobic exercise variables are seriously affected by post-viral fatigue syndrome, and one year may not be sufficient to fully recover.

TL;DR: The results obtained justify arthroscopic treatment of unilateral mediopatellar synovial plica of the knee in a young, extremely active population.
Abstract: MAFFULLI, N., V. TESTA, and: G. CAPASSO. Mediopatellar synovial plica of the knee in athletes: results of arthroscopic treatment. Med. Sci. Sports Exerc., Vol. 25, No. 9, pp. 985–988, 1993. The long-term results (9–87 months) of the arthroscopic treatment of unilateral mediopatellar synovial plica of the knee in 102 athletes are reported. In all patients a large and/or fibrotic inflamed mediopatellar plica impinging on the femoral condyle on knee flexion was identified and trimmed. Chondromalacia patellae was detected in 38 patients. The impingement lesion was seen in 13 knees. In one patient, a minor tear of the lateral meniscus was trimmed, and one patient was found to suffer from a clinically asymptomatic partial tear of the anterior cruciate ligament. Isometric strength testing of the quadriceps revealed marked decrease at the second postoperative week, with subsequent gradual recovery. The results obtained justify arthroscopic treatment in a young, extremely active population.

TL;DR: The appearance of regenerate bone during the process of limb lengthening using a mono-axial device was studied using radiographs and ultrasound scanning in nine patients and a clear impression of a new cortical margin was seen.
Abstract: The appearance of regenerate bone during the process of limb lengthening using a mono-axial device was studied using radiographs and ultrasound scanning in nine patients. The corticotomy site initially appeared as a sonolucent area. Poorly organized echogenic foci were detectable 2 weeks after the distraction was begun. After 4 weeks, these areas became aligned. At 7-8 weeks, a clear impression of a new cortical margin was seen. The formation of a medullary canal started at this point, progressing to a radiographically evident canal. Ultrasound scanning can reduce considerably exposure to ionising radiation in patients undergoing limb lengthening. Accurate measurements are possible in the early stages, and ossification can be monitored. Axial deviation can be seen but not evaluated. The maturity of the regenerate bone still has to be assessed clinically.
