We report the case of a 44-year-old man who underwent a partial medial meniscectomy for a meniscal tear whose postoperative course was complicated by the development of heterotopic ossification (HO) within the medial arthroscopic portal. Following a routine initial procedure, the patient presented with ongoing pain and a palpable, painful lump around the previous medial arthroscopy portal. Plain radiographs and MRI were suggestive of a bony structure within the soft tissues. Histopathological examination at repeat arthropscopy confirmed osseous tissue consistent with HO. Recovery after the second procedure was rapid and resulted in normal knee function and complete pain relief. HO within an arthroscopy portal is a rare complication following arthroscopic partial meniscectomy in the knee and has not previously been described in the literature. 相似文献

AimTo define arthroscopic meniscectomy (AM) outcomes in young patients at 20 years follow up in terms of predictors of poor clinical results, rate and timing of conversion to total knee replacement (TKR).MethodsThe following data were collected for 225 patients aged between 18 and 50 years with meniscal tear (MT) who underwent AM: age at surgery, gender, injured meniscus, knee alignment, associated lesions, amount of meniscal resection. At 20 years follow up, rate and timing of TKR conversion and clinical outcomes with Knee injury and Osteoarthritis Outcome Score (KOOS) score were reviewed.ResultsTen patients (4.4%) required TKR in the follow up period. The mean time from AM to TKR was 7.0 years (standard deviation 3.87). Age between 40 and 50 years at AM (P < 0.01), malalignment (P < 0.01), lateral meniscectomy (any size, P = 0.01), advanced chondral lesion (Outerbridge > 2, P < 0.01) and total meniscectomy (P < 0.01) were significantly related to subsequent TKR. Negative predicting factors to obtaining equal or superior to age/sex-adjusted KOOS score were age between 40 and 50 years old at time of AM (P < 0.01), female sex (P < 0.01), malalignment (P = 0.04), and advanced chondral lesion (Outerbridge > 2, P = 0.02).ConclusionsTwenty years conversion rate to TKR after AM for MT is 4.4% and TKR was performed after a mean time of 7 years. Significant association between TKR surgery and advanced chondral lesion (Outerbridge > 2), total meniscectomy, lateral meniscectomy, age at surgery between 40 and 50 years old, and malalignment were found. Age between 40 and 50 years at time of AM, female, malalignment, advanced chondral lesion were all factors significantly related to poor clinical results. 相似文献

Summary The purpose of this study was to examine the effect of intense interval training on erythrocyte 2,3-diphosphoglycerate (2,3-DPG) levels at rest and after maximal exercise. Eight normal men, mean ± SE=24.2±4.3 years, trained 4 days·week–1 for a period of 8 weeks. Each training session consisted of eight maximal 30-s rides on a cycle ergometer, with 4 min active rest between rides. Prior to and after training the subjects performed a maximal 45-s ride on an isokinetic cycle ergometer at 90 rev·min–1 and a graded leg exercise test (GLET) to exhaustion on a cycle ergometer. Blood samples were obtained from an antecubital vein before, during and after the GLET only. Training elicited significant increases in the amount of work done during the 45-s ride (P<0.05), and also in maximal oxygen uptake (
max: Pre=4.01±0.13; Post=4.29±0.07 l·min–1;P<0.05) during exercise and total recovery
(Pre=19.14±0.09; Post=21.45±0.10 l·30 min–1;P<0.05) after the GLET. After training blood lactate was higher, base excess lower and pH lower during and following the GLET (P<0.05 for all variables). Training caused no significant differences in erythrocyte 2,3-DPG levels at rest (Pre=11.8±0.7; Post=12.1±0.7 mol·g–1 hemoglobin (Hb);P>0.05), at exhaustion (Pre=12.0±0.8; Post=11.2±0.8 mol·g–1 Hb;P>0.05) or during 30 min of recovery from the GLET. Additionally, acute exercise (pre-training GLET) did not effect any change in 2,3-DPG at exhaustion or during recovery from exercise compared to resting values. The higher
max and total recovery
values observed after training appear to be unrelated to 2,3-DPG levels. Under the present conditions, the role, if any, of 2,3-DPG in enhancing tissue oxygenation during increased metabolic demand remains obscure.Supported by grants from Miles Laboratories, Elkhart, Indiana, and the Ball State Graduate Student Research Fund 相似文献

In men, the hypothalamic-pituitary-testicular axis controls the secretion of testosterone which, in this sex, is a major anabolic hormone. Physical exercise modulates testosterone concentration, affecting the whole axis by poorly understood mechanisms. We have reported in this preliminary study the short and longterm effects of exercise on the function of the gonadotropic axis in trained compared to untrained subjects. Environmental factors known to interfere with pituitary function were minimized. Four marathon and four sedentary men, were studied during 5 days successively using different combinations of two factors: duration and intensity of running tests. Day 0 (DO) was a rest day, and the exercises were: D1 and D2 brief (20 min), light (50% maximal heart rate, HRmax, D1) or intense (80% HRmax, D2), D3 and D4 prolonged (120 min) and light (50% HRmax, D3) or intense (80% HRmax, D4). Testosterone (free and total) and luteinizing hormone (LH) concentrations were measured before, during and after exercise. The baseline concentrations of plasma testosterone were lower in the long distance runners than in the sedentary group [41.8 (SEM 5.5) vs 64.5 (SEM 7.9) pmol · 1–1, respectively;P < 0.05]. This phenomenon was centrally mediated as LH concentration was apparentlyinappropriately low [3.4 (SEM 0.4) vs 4.3 (SEM 1.0) UI · 1–1;P > 0.05]. Light to moderate exercise did not modify testosterone and LH concentrations. Conversely, intense and prolonged exercise increased testosterone concentration [73.2 (SEM 9.0) vs 92 (SEM 11.0) pmol · 1–1 in the long distance runners and sedentary group, respectively;P < 0.05] and lowered LH concentrations [2.1 (SEM 0.3) vs 3.4 (SEM 0.3) UI · 1–1 in the long distance runners and sedentary group, respectively;P <0.05 compared to DO, at the same time]. In our conditions of exercise, negative feedback of testosterone upon LH persisted, as positive feedback of low testosterone concentrations was apparently lacking (inappropriately low LH concentration with regard to low basal testosterone concentration). 相似文献

BackgroundKnee osteoarthritis (OA) severity is a predictor of outcomes after arthroscopic partial meniscectomy (APM). Magnetic resonance imaging (MRI) grading of OA is predictive of postoperative outcomes; this prospective study assessed whether radiographic grading is also predictive of outcomes.MethodsPatients who underwent APM between February 2015 and January 2016, underwent radiography and MRI ≤ 6 months before surgery, and had outcomes from the surgery date and one year later were included. Surgical failure was defined as < 10-point improvement in the Knee Osteoarthritis Outcome Score pain subscore. Radiographs were evaluated using Kellgren-Lawrence (KL) grading and continuous and ordinal minimum joint space width (mJSW) measurements; cartilage loss on MRI was evaluated using a modified Outerbridge system. Predictive abilities were estimated using area under the receiver operating characteristic curve (AUC) with 95% confidence intervals (CIs).ResultsThe study cohort included 66 knees from 64 patients (32 women; mean age, 57.1 years; range, 45–77). Radiographic grading was not predictive of outcomes (KL, AUC = 0.541 [95% CI: 0.358, 0.724]; continuous mJSW, AUC = 0.482 [95% CI: 0.305, 0.659]; ordinal mJSW, AUC = 0.534 [95% CI: 0.433, 0.634]). Comparison of radiographs showing no joint space narrowing (KL grade 0–2) with corresponding MR images demonstrated that 48% of radiographs missed a clinically significant lesion (modified Outerbridge grade ≥ 3). MRI grading was predictive of outcomes (AUC = 0.720 [95% CI: 0.581, 0.859]).ConclusionsRadiographic grading of OA is not predictive of outcomes after APM; radiographs may miss clinically significant lesions. For outcome prediction, MRI should be used. 相似文献

The purpose of this study was to examine the effect of a recovery period between two periods of exercise on bone metabolism
and related hormones. Concentrations of serum parathyroid hormone ([PTH]), plasma ionized calcium ([Ca2+]) and total calcium were measured. A group of 12 healthy men aged 20–27 years participated in this study. They took part
in two exercise protocols (P1 and P2) on two separate weeks. The exercise in P1 comprised two successive periods of 21 min each at 70% and 85% of maximal oxygen uptake; P2 comprised two periods of exercise at the same intensities but separated by 40 min of recovery. Venous blood samples were
collected 1 day before the sessions (control), before each protocol, during (7th and 21st min), at the end (42nd min in P1 and 82nd min in P2) and after 24 h of recovery. The [PTH] was significantly elevated during the two protocols (P<0.01), remained raised in P1 after 24 h of recovery (P<0.05) and was significantly lower (P<0.01) at the end of P2 when compared to P1. The [Ca2+] decreased significantly during and at the end of the two protocols (P<0.01) and had returned to control values after 24 h of recovery. Plasma lactate concentration increased during the two protocols
(P<0.01) and returned to control values after recovery. These results indicate firstly that [Ca2+] decreases during continuous exercise as [PTH] increases and remains raised after 24 h of recovery, secondly that a recovery
period between two periods of exercise attenuates the variations in [Ca2+] and [PTH], and thirdly that recovery may have anabolic effects on bone. However, the small physiological changes observed
prevent us from forming any firm conclusion about this.

Summary Up to 30% of all operative procedures in orthopaedic surgery are performed arthroscopically. Because of the steadily increasing number of residents, it seems to be difficult both to maintain high standards and to guarantee an adequate training in arthroscopic surgery. However, in contrast to many other surgical techniques it is possible to learn and practice arthroscopy using artificial models and cadaver joints, provided that experienced surgeons and anatomists act as supervisors and instructors. The aim of this paper is to assess practice models and training programs which should guarantee sufficient practical experience during the training period.
Modèle d'apprentissage et d'entraînement à la chirurgie sous arthroscopie
Résumé Jusqu'à 30% de toutes les techniques opératories en chirurgie orthopédique sont réalisées sous arthroscopie. En raison du nombre croissant de résidents, il semble difficile de maintenir à la fois le haut niveau de formation et de garantir un entraînement adéquat à la chirurgie sous arthroscopie. Toutefois, contrairement à de nombreuses autres techniques chirurgicales, il est possible d'apprendre à pratiquer l'arthroscopie en utilisant des modèles artificiels ou des articulations de cadavres, dans la mesure où des chirurgiens et des anatomistes expérimentés agissent comme enseignants et tuteurs. Le but de ce travail était d'évaluer les modèles pratiques et les programmes d'entraînement pouvant garantir une expérience pratique suffisante durant la période d'apprentissage.相似文献

Summary Thirteen men were submitted to graded exhaustive cycle exercise to determine the kinetics of proteinuria in the recovery period.
Venous blood samples were analysed for haematocrit, lactate, creatinine, total protein and albumin for 1 h following exercise.
Urine samples were collected during a 3-h recovery period. Total protein, albumin, and creatinine levels were determined for
these samples. Total protein and albumin urinary excretion increased to 581 and 315 μg min−1, respectively, at the end of the 1st h of recovery as compared to 42 and 15 μg · min−1 for resting values. Plasma volume returned to pre-exercise levels between 30 and 60 min after cessation of exercise, while
urinary total protein and albumin content still remained above the resting values for the following 2 h. Both post-exercise
urinary total protein and albumin excretion followed a logarithmic decline with the same half-life of 54 min, thus requiring
about 4 h to regain resting values. The reduction of plasma volume and the degree of dehydration do not seem to be involved
in the process. The present study indicates the delayed recovery of protein handling by the kidney, as compared with other
biochemical parameters, and provides accurate information on the kinetics of post-exercise proteinuria. 相似文献

In this paper new insights into the beneficial effects of physical training for patients with coronary artery disease are
reviewed. Endurance training as part of a comprehensive cardiac rehabilitation programme in combination with strength training,
smoking cessation and lipid management may slow down and in some cases reverse the progress of coronary atherosclerosis. Thus,
exercise training remains an invaluable tool in the hands of the clinical cardiologist dealing with chronic coronary care.

Background: Level exercise leads to focal structural damage in muscle fibers and to an increase of creatine kinase in the blood. We questioned whether it also induces activation of young and adult muscle satellite cells toward proliferation. Methods: Rats of two different ages, 6 and 16 weeks, were forced to run on a level treadmill and killed at different time intervals. The temporal profile, up to 3 weeks, of muscle damage was investigated by quantification of the focally disturbed fiber area in longitudinal sections of the m. soleus. Bromodeoxyuridine (BrdU) was injected before death to determine the labeling index of satellite cells. Labeled and unlabeled satellite cells, myonuclei, and fibers were counted in cross sections of the belly part of the muscles. Results: The muscle fiber damage differed in both amount and temporal profile between young and older animals. Damage was already visible immediately after running. However, whereas in the younger animal the amount of damage increased gradually in time until 8% at 48 hours and disappeared to almost control levels at 1 week after running, in the older animals the amount of damage was lower but remained present for at least 2 weeks. The cell kinetic data on both groups showed a proliferation response of satellite cells throughout the muscle. The effects were most pronounced in the older rats. In these rats a large increase of the labeling index was found between 24 hours and 1 week, whereas the total number of satellite cells was consistently higher from 2 days on until 2 weeks after running. In the younger animals roughly the same time pattern was observed. Conclusion: Since the damage differed in amount and time between the two age groups, we conclude that the quick and huge proliferation response is due to leakage of mitogenic factors through small membrane disruptions that are generated during the exercise itself. © 1995 Wiley-Liss, Inc. 相似文献

Summary Changes in the testosterone concentrations after single sessions of endurance and strength training were measured in seven well trained men, experienced in both forms of training. Both training sessions were rated as hard to very hard on the Borg scale. Blood samples for testosterone measurements were taken before, immediately after, and 2, 4 and 6 h after the training sessions as well as the next morning. The mean tes tosterone concentration increased 27% (P<0.02) and 37% (P< 0.02) during the strength and endurance training session, respectively. Two hours after the training sessions the mean testosterone concentration had re turned to the pre-training level and remained at that level for the length of the observation period. There were no significant differences in the changes in testosterone concentration after strength and endurance training but there were large differences in the testosterone response at the level of the individual. A high correlation (r=0.98;P<0.001) for individuals was found between increases in testosterone concentration after strength and after endurance training. It was concluded that the changes in mean testosterone values followed the same timecourse after single sessions of strength and endurance training of the same duration and perceived exertion. The interindividual differences in tes tosterone response may be of importance for individual adaptation to training. 相似文献

The effects of exercise and sleep loss on recovery sleep were studied in young male naval volunteers. For 1 hr out of every 4 hrs during a 40-hr period, 20 subjects rested in bed and 10 subjects bicycled. Eleven measures of recovery night sleep were selected for comparison of the bedrest and exercise groups. Only one reached significance under the conservative Dunn-Bonferroni criterion: the exercise group had a higher percent total sleep time. The results indicate that exercise does increase the effects of sleep loss on recovery sleep, but that there is no simple, direct effect on specific sleep stages. 相似文献

Exercise intolerance in heart transplant recipients (HTR) has a multifactorial origin, involving complex interactions among cardiac, neurohormonal, vascular, skeletal muscle and pulmonary abnormalities. However, the role of these abnormalities may differ as a function of time after transplantation and of many other variables. The present review is aimed at evaluating the role of cardiac, pulmonary and muscular factors in limiting maximal aerobic performance of HTR, and the benefits of chronic exercise. Whereas pulmonary function does not seem to affect gas exchange until a critical value of diffusing lung capacity is attained, cardiac and skeletal muscle function deterioration may represent relevant factors limiting maximal and submaximal aerobic performance. Cardiac function is mainly limited by chronotropic incompetence and diastolic dysfunction, whereas muscle activity seems to be limited by impaired oxygen supply as a consequence of the reduced capillary network. The latter may be due to either immunosuppressive regimen or deconditioning. Endurance and strength training may greatly improve muscle function and maximal aerobic performance of HTR, and may also reduce side effects of immunosuppressive therapy and control risk factors for cardiac allograft vasculopathy. For the above reasons exercise should be considered an important therapeutic tool in the long-term treatment of heart transplant recipients. 相似文献

Summary Arterial blood lactate concentrations were measured in six normal males before, during and after 3 and 6-min bicycle exercises
performed at three different work rates. The lactate recovery curves were fitted to a bi-exponential time function consisting
of a rapidly increasing and a slowly decreasing component, which supplied an accurate representation of the changes in lactate
concentration. Variations in the parameters of this mathematical model have been studied as a function of the duration of
exercise and of the work rate, showing a clear dependence on exercise duration such that increasing exercise length decreases
the velocity constants of the fitted curves. In terms of the functional meaning which can be given to these constants, this
result indicates that extending exercise duration from 3 to 6 min reduces the ability of the whole body to exchange and remove
lactate. This effect did not qualitatively modify the one already described, which is due to increased work rates, but it
shifted the ability to exchange and remove lactate towards lower values. The main conclusion of the study is that lactate
kinetic data vary as a function of time during exercise. This inference must be accounted for in the interpretation of lactate
data obtained during muscular exercise. 相似文献
