Summary For 182 knee joints with ligamentous injuries confirmed at surgery the records contained a complete and documented stability examination. In anterior cruciate ligament injuries the Lachman test and the anterior drawer sign were of similar value with regard to the frequency of false negatives — they missed half of the injuries — but their accuracy improved when they were repeated under anesthesia. The pivot shift was useful only under anesthesia. The medial collateral ligament injuries were usually detected because of valgus instability, also without anesthesia. The stability tests done with the patient under anesthesia are sufficiently reliable for making decisions about knee ligament surgery. 相似文献

Arthrometry was performed before and during anesthesia in 41 patients with acute or old anterior cruciate ligament injuries and only minor signs of valgus or varus instability. The uninjured contralateral knee served as a control. The influence of anesthesia on the anterior stability was distinct in acute knee injuries. There was also a small, but definite, increase in anterior laxity in uninjured knees. Knees with old injuries were more lax, and the injured-uninjured difference in anterior laxity was more pronounced. Stability examination under anesthesia is of great value for acutely injured knees. 相似文献

During 1959 to 1986, 62 Cases with cruciate ligament injury of the knee joint were treated in our hospital. Thirty of these cases were anterior cruciate ligament injuries and 32 cases were posterior The diagnosis of the cruciate ligament injuries was made by stability tests of the cruciate ligament. When the knee was greatly swollen with multiple ligament injuries, a series of X-ray films should be taken to test the knee stability under local or nerve block anesthesia. Fresh tear of the cruciate ligament (33 cases) was treated with immediate surgical repair except in one. Old ligament injuries (28 cases) were treated by conservative method (10 cases) or surgical reconstruction (18 cases). All patients were followed for 2 to 18 years (mean 6 years). The results showed that the fresh tear of the cruciate ligament treated surgically had excellent and good rates in 87.9% (29/33). In the conservative treatment group, only 27.3% (3/11) obtained good result, and most of them were complicated with meniscal lesions and osteoarthritis. Eighteen cases treated by ligament reconstruction gave 34.5% (8/18) good result. 相似文献

Comparison of magnetic resonance imaging with operative findings in acute traumatic dislocations of the adult knee 总被引:1,自引:0,他引:1
OBJECTIVES: To compare magnetic resonance imaging (MRI) with examination under anesthesia and with surgical findings in evaluating soft tissue injuries in acute traumatic knee dislocations in adults. DESIGN: Retrospective analysis. SETTING: Level I trauma center. PATIENTS: For a single surgeon, all patients who underwent MRI before surgical treatment for knee dislocations (ten individuals). INTERVENTION: Incompetent ligaments were repaired or reconstructed. MAIN OUTCOME MEASUREMENTS: MRI of knee dislocations was compared with clinical examination under anesthesia and with intraoperative findings at arthrotomy in ten cases. Pertinent positive and negative findings were recorded, and accuracy, sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: Two mid-grade sprains of the anterior cruciate ligament were erroneously read as complete tears. One rupture or avulsion of each the biceps tendon, the lateral collateral ligament, and the posterolateral and posteromedial corners were considered intact on MRI. The MRI studies erroneously identified tears of the lateral collateral ligament and medial meniscus in one case each. Otherwise, the study was highly accurate. CONCLUSIONS: MRI is useful for defining the presence of ligamentous injuries in knee dislocations; however, clinical examination under anesthesia is more accurate. 相似文献

The objective of this study was to define the role of early diagnostic knee arthroscopy for patients with an acute knee injury and hemarthrosis. Forty-five patients with an acute knee injury followed by a posttraumatic hemarthrosis during a 1-year period were prospectively reviewed. All patients were evaluated preoperatively followed by examination under anesthesia and arthroscopy of the knee. The majority of patients, 32 (71%), had an anterior cruciate ligament tear. Meniscal tears occurred in 21 patients (47%). Meniscal tears requiring surgery occurred in only 10 of 25 meniscal tears (40%). Seven patients (16%) had medial collateral ligament and/or posteromedial capsular sprain. Eight patients (18%) had an osteochondral fracture or patellar dislocation associated with an osteochondral fracture. The majority of knees with a torn meniscus or osteochondral fracture had an anterior cruciate ligament tear. Clinically, 18 of 21 knees (86%) with an acute complete anterior cruciate ligament tear were diagnosed preoperatively with the Lachman test. The Lachman test conducted with patients under anesthesia was positive for 19 of 21 knees (90%) with an acute complete anterior cruciate ligament tear. The preoperative examination correctly identified six of seven knees (86%) with a medial collateral ligament sprain. The preoperative Lachman test was positive in only two of five knees (40%) with a partial anterior cruciate ligament tear. The Lachman test with patients under anesthesia was positive for four of five knees (80%) with an acute partial anterior cruciate ligament tear. Preoperative examination yielded the correct diagnosis in only 9 of 21 knees (43%) with a meniscal tear and 1 of 6 knees (17%) with an osteochondral fracture.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Gabapentin has antihyperalgesic and anxiolytic properties. We thus tested the hypothesis that premedication with gabapentin would decrease preoperative anxiety and improve postoperative analgesia and early postoperative knee mobilization in patients undergoing arthroscopic anterior cruciate ligament repair under general anesthesia. Forty patients were randomly assigned to receive 1200 mg oral gabapentin or placebo 1-2 h before surgery; anesthesia was standardized. Patients received morphine, 0.1 mg/kg, 30 min before the end of surgery and postoperatively via a patient-controlled pump. Pain scores and morphine consumption were recorded over 48 h. Degrees of active and passive knee flexion and extension were recorded during physiotherapy on days 1 and 2. Preoperative anxiety scores were less in the gabapentin than control group (visual analog scale scores of 28 +/- 16 mm versus 66 +/- 15 mm, respectively; P < 0.001). The gabapentin group required less morphine than the control group (29 +/- 22 mg versus 69 +/- 40 mg, respectively; P < 0.001). Visual analog scale pain scores at rest and after mobilization were significantly reduced in the gabapentin group. First and maximal passive and active knee flexions at 24 and 48 h were significantly more extensive in the gabapentin than in the control group. In conclusion, premedication with 1200 mg gabapentin improved preoperative anxiolysis, postoperative analgesia, and early knee mobilization after arthroscopic anterior cruciate ligament repair. 相似文献

The fibular head sign is a clinical finding that seems not to have been previously reported for the diagnosis of chronic anterior cruciate ligament insufficiency (ACLI) associated with lateral rotatory instability of the knee joint. The fibular head could be palpated as a prominent bony lump, felt subcutaneously in the posterior lateral corner of the popliteal fossa. In a prospective study of 20 patients with ACLI, the mean age of the patients (15 males, five females) at the time of assessment was 26 years (range, 18-57 years). The left knee was involved in 11 patients, the right knee in the remaining nine patients. All the patients sustained their knee ligament injury in sporting activities except one patient who was involved in a motor vehicular accident. The majority of the patients had instability-related symptoms for more than six months. After history taking, physical examination in the clinic, and examination under anesthesia, and arthroscopy in the operating room of all patients, it was determined that there were 13 ACL injuries, four posterior cruciate ligament (PCL) injuries, and three combined A/PCL injuries. All ACL injury patients had a prominent fibular head sign. Other associated signs included passive hyperextension of 10-20 degrees, and major anterolateral, and to a lesser degree a posterolateral, rotatory instability. The fibular head sign was negative in isolated posterior cruciate injuries and in combined A/PCL injuries. 相似文献

A prospective study was done of 29 patients with conservatively treated partial ruptures of the anterior cruciate ligament that were stable at the initial examination under anesthesia. The ruptures were reevaluated for stability and knee function from 12 to 60 months after injury. Many had developed signs of instability. The forward drawer sign (Lachman test) and the pivot shift tests were positive. There was also measurable sagittal instability (anterior drawer sign). In every case, knee function was almost completely restored. 相似文献

All players in Swedish soccer teams are required to have insurance in the same company. From the archives of the insurance company, all 3,735 injuries reported in 1986 in 188,152 Swedish soccer players were reviewed. Of these, 937 were knee injuries. All players were asked by mail to fill in a questionnaire and 83 percent replied. The patient records from the different hospitals were requested. The anterior cruciate injuries represented one third of the reported knee injuries.
The relative risk of sustaining an anterior cruciate ligament Injury was increased in female players, in elite players, and in players in the forward position. The odds ratios were 1.6 (1.3-2.1), 3.3 (1.7-6.1) and 1.8 (1.4-2.5), respectively. The injuries occurred at a younger age in females than in males. 50 percent of the injured players were treated with anterior cruciate ligament surgery, predominantly as a reconstructive procedure, with use of a patellar tendon transplant. 30 (20) percent of the players with anterior cruciate ligament injury were active in soccer after 3 (7) years, compared to 80 (50) percent of an uninjured control population of soccer players. None of the elite players was active at the same level after 7 years. A comparison of anterior cruciate ligament-injured players, whether treated by surgical reconstruction or not, revealed no difference with regard to the proportion of players still playing soccer after 7 years. 相似文献

The measurement of anterior knee laxity in anterior cruciate ligament injuries is an established method for both clinical practice and clinical studies in regard to anterior cruciate ligament surgery. Stress radiography was succeeded or paralleled by instrumented testing with the development of standardized devices starting in the 1980s. Because knee stability depends on the flexion angle test, conditions need to be comparable for both instrumented testing and stress radiography. The lack of a general consensus becomes even more evident for testing and measuring rotational instability. Knee laxity measurement in all dimensions, such as with robots in cadaver studies, has not found its general application in the clinical setting yet, but will be expected in the near future. 相似文献

The purpose of this study was to identify neuromuscular characteristics related to dynamic restraint in the knee. Observing compensatory changes to these characteristics in women with anterior cruciate ligament injuries provides important information for understanding functional knee stability, injury prevention, and performance. Twelve female subjects with anterior cruciate ligament injuries and 17 female control subjects participated in this study to assess electromyographic activity during landing from a hop and knee perturbation; hamstring muscle stiffness and flexibility; and isokinetic strength. Females with anterior cruciate ligament deficiencies had significantly increased preparatory muscle activity in the lateral hamstring before landing, but no differences in reactive muscle activity during landing or reflex latency after joint perturbation. Females with anterior cruciate ligament deficiencies had significantly less hamstring muscle stiffness and flexibility, but also had greater peak torque and torque development for knee flexion. Lower Lysholm scores were observed in females with anterior cruciate ligament deficiencies but no difference was found in functional performance of the single leg hop test. These neuromuscular characteristics provide a foundation for future research investigating injury prevention and rehabilitation techniques that maximize dynamic restraint through stiffness regulation and the timing of specific muscle activation strategies. 相似文献
