Stabilité posturale après reconstruction du ligament croisé antérieur

Injury of the anterior cruciate ligament (ACL) leads to static and dynamic instability, with a risk of joint degeneration. The purpose of surgical reconstruction is to re-establish joint stability and function. It does not restore the sensorial system. The purpose of this work was to compare, in terms of postural stability, healthy knees and operated knees five years after ligamentoplasty versus 31. A dynamic posturography device was used for assessment. It was concluded that there was no difference between the two groups concerning postural stability.     

La reconstruction du ligament croisé antérieur aux tendons ischiojambiers chez les sportifs de haut niveau. Étude prospective de 30 cas

Introduction

Anterior cruciate ligament (ACL) reconstruction using hamstring graft under arthroscopy makes it possible to restore the stability of the knee allowing an early resumption of the sport. Our study aims to determine in the high level sportsmen; clinical, organic and therapeutic characteristics through the revision of a clinical series, analyzed about literature.

Material and methods

It is about a prospective Moroccan study of 30 high-level sportsmen having profited from an ACL ligamentoplasty under arthroscopy. All the patients were re-examined with three years the average retreat. Our patients was level 7 of Tegner and 30% of them were professional footballers. The therapeutic time was three years on average. The intervention proceeded under arthroscopy using hamstring graft, the fixation was ensured by screw in femur and another screw associated with staples with barbs in tibia. The protocol of rehabilitation early and was adapted to the practiced sport.

Results

The average follow up was three years. According to the quotation of Lysholm, we noted 86% from goods and excellent results, 10% of average results and 4% of bad results. According to objective score of International Knee Documentation Committee (IKDC), we noted 43% of classified patients rank A, 51% of rank B, and 6% of rank C. To the KT-1000, average differential laxity was of 1.8 mm. The average time of resumption of the competition was six months.

Discussion

The use of hamstring graft for the petitioning high level sportsman salary of an early recovery, gave us satisfaction in spite of residual laxity. In our study, the average time of resumption of the competition was six months. These results are encouraging compared to the remainder of the studies published where the resumption of the competition is recommended between sixth and the tenth month, some is the transplant used.     

Ostéotomies tibiales de valgisation associées à la ligamentoplastie du ligament croisé antérieur. À propos de 15 cas

The management of patients aged 30 to 50 years and with an anterior knee laxity in ACL tear associated with medial osteoarthritis femorotibial, is very difficult. Recent publications have shown that the combination of an valgus osteotomy and ligamentoplasty of the ACL is possible to halt the progression of osteoarthritis while correcting the laxity of the knee. We report our experience of 15 patients who received a valgus osteotomy associated with the ACL ligamentoplasty.     

Traitement conservateur de la rupture du ligament croisé antérieur

The aims of non-operative treatment of anterior cruciate ligament injuries are to promote dynamic stability, improve function and decrease the risk of osteoarthritis. There is controversy in the studies with heterogeneous and non- randomized samples, currently recommending this treatment for isolated ruptures, elderly adults and patients without motivation for physical activity. Patient education, range of motion rehabilitation, hamstring and quadriceps muscle strengthening, proprioception training in closed kinetic-chain and fitness reconditioning are the most important approaches to a functional return.     

Fonction et niveau d’activité physique deux à cinq ans après la reconstruction du ligament croisé antérieur (LCA)

Objectives

Evaluation of functionality and level of physical activity in patients 2 to 5 years after anterior cruciate ligament reconstruction.

Material and methods

A nonrandomized study, which included consecutive patients (n = 31) who underwent ACL reconstruction and were evaluated 2-5 years after ligament reconstruction. The surgical techniques used were the bone-patellar tendon-bone graft (BTB), quadriceps tendon (QT) and semitendinosus gracilis tendons (ST-G). The clinical evaluation included the Tegner activity Index (TI), Lysholm Index (LI), Index Knee Outcome Survey (KOS) in their sub-divisions “Total”, “Activities of Daily Living” and “Functionality” (KOS-T, KOS-ADL, KOS-IF) and Noyes Test (NT). The Package for Social Sciences (SPSS) version 17.0 for Windows was used for the statistical study.

Results

Before injury, the TI was 6.74 and after injury 4.35; the LI average was 89.55; the KOS-T was 70.48, KOS-ADL 30.48 and KOS-FI 39.95; and the NT gave a symmetry score of 96.6%. No significant correlations were found between the values of the TI before and after injury, or between the values of the LI and KOS-ADL, and the LI and NT.

Conclusion

ACL injury is associated with a high number of meniscal and chondral injuries, with direct impact on the prognosis of these patients’ sport activity and a reduction in activity levels. This reduction is not accompanied by a significant functional loss and normal daily activities are unaffected. The motivation of the patient and medical advice are considered key factors in promoting recovery to the pre-lesional level.     

Pente tibiale et rupture du ligament croisé antérieur : étude anatomoradiologique

Studies of knee-joint anatomy and biomechanics have demonstrated a main intrinsic factor having a negative impact on the anterior cruciate ligament (ACL): a weak tibial slope. The purpose of this work was to study tibial slope measured on plain X-rays in knees with and without ACL tears.     

Fracture-avulsion de l’insertion tibiale du ligament croisé postérieur chez un enfant. À propos d’un cas et revue de la littérature

The isolated lesion of the posterior cruciate ligament (PCL) and in particular the tibial avulsion is a rarely reported entity on immature skeleton. We report a case of isolated avulsion fracture of the tibial insertion of PCL in a young athlete of 14 years old, treated surgically with good functional results 2 years later.     

Revue de littérature : la rupture du ligament croisé antérieur : particularités féminines

We know that female athletes practicing pivoting sports have a higher risk of anterior cruciate ligament (ACL) injury compared to male. Many series confirm that the risk is four to seven times higher among female athletes at the same sporting level. Furthermore, most ACL injuries in female athletes occur during a noncontact episode, typically during deceleration, lateral pivoting or landing. A literature review confirms the higher incidence of ACL injuries among women in the pivot sports with or without contact. This sex difference can be explained by external and internal risk factors. The external risk factors are competition in games versus training, footwear and playing surfaces, protective equipment and physical preparation. The internal risk factors are anatomical risk factors: anatomy of the notch, posterior tibial slope, hyperlaxity, biomechanical factors: kinematics and kinetics of the knee, neuromuscular risk factors and hormonal risk factors. Indeed, the hormonal factors (estrogen, relaxin, progesterone and testosterone) seem to be responsible, especially during the ovulatory phase of the menstrual cycle. This study confirms that female athletes have a higher risk of ACL injuries compared to male athletes. A better knowledge of the external and internal risk factors, such as the injury mechanism and the hormonal factors may help in the future prevent these injuries.     

Hospitalisation en court séjour pour reconstruction du ligament croisé antérieur : étude prospective comparative

Introduction

In France, the median duration of hospitalization for a reconstruction of the anterior cruciate ligament (ACL) is 3 days. The purpose of this study was to evaluate the feasibility and acceptability of hospitalization for one day for this surgery.

Patients and methods

A prospective study conducted in 2011 included patients who underwent surgery for an ACL rupture. Exclusion criteria were age > 60 years, scores ASA3-4 and patients unmanageable in short-stay. Two groups of patients were formed: “short-stay” with an output at D1 and “conventional hospitalization” with an output at D3. The postoperative analgesia protocol included analgesics I-II, morphine on demand during hospitalization. “Short-stay” group received a telephone follow-up (D1–D4). The primary outcome was patient satisfaction at D3. The secondary endpoints were postoperative pain assessed on a visual analogue scale at D3 and adverse events. Thirty patients were included in each group, 34 men and 26 women, mean age 29 ± 5 years.

Results

Patients in group “short-stay” were on average more satisfied than the “conventional hospitalization” group, P = 0.01. The pain was significantly less pronounced in the “short-stay” group, P = 0.00001. No complications occurred.

Conclusion

Inpatients short-stay were significantly more satisfied and less painful than those in conventional hospitalization group. Future studies should evaluate the feasibility of ambulatory surgery for ACL reconstruction.     

Les kystes du ligament croisé antérieur : à propos de 24 cas

The purpose of this study is to present clinical and magnetic resonance imaging (MRI) features of ganglion cysts of the anterior cruciate ligament (ACL). Such cysts are rare and often unsuspected. We reviewed a series of 24 ganglion cysts of the ACL (7 females, 17 males) between 1998 and 2004. The mean age was 45 years old (25–74). All patients presented with knee pain. The mean follow-up was 25 months (6–48). All patients had a preoperative MRI, which confirmed the diagnosis. Seventeen patients had an arthroscopic treatment and 7 were treated with percutaneous aspiration and steroid injection under. Fourteen patients were evaluated with the International knee Documentation Committee (IKDC) subjective score. Computed tomography or ultrasound guidance. MRI demonstrated 16 mucoid degenerative cysts of the ACL and 8 well circumscribed ganglion cysts with a fluid collection. The surgical pathology confirmed 13 mucoid cysts and 4 ganglion cysts; 2 recurrences were observed after surgical treatment. After percutaneous aspiration, we observed 3 recurrences, 2 failures and one vascular complication. We observed two types of ACL cysts, which could be differentiated on the MRI. Percutaneous treatment was less reliable than surgical treatment. The percutaneous aspiration should be reserved to the ganglion cysts with fluid collection, while arthroscopy is indicated for the failure cases. We recommend resection for the mucoid cysts. An aggressive resection of the ACL may compromise the knee stability so that the patient must be informed preoperatively. In theses cases, aspiration was often inefficient.     

Épidémiologie des ruptures du ligament croisé antérieur du genou chez la joueuse de football de haut niveau : à propos de 66 cas

Our study focussed on the rupture of the anterior cruciate ligament in high level female soccer players in first and second national divisions. To this effect, we used a questionnaire to analyse 66 cases of anterior cruciate ligament injury according to the following criteria: age at the time of injury, the side injured, laterality, circumstances of the accident, the type of treatment (surgical or functional), the type of surgery, recovery time, the level of recovery, initial care in a rehabilitation centre. Rupture is generally due to a non-contact injury (65%), which is comparable with a male population of the same level. The risk of repeated rupture, in a player continuing her career, is significant (> 10%). The type of surgery does not affect return to sport. However, for high-level female soccer players, rehabilitation in a specialised centre improves the chances of returning at the same level (p < 0.025).     

Influence du type d’orthèse de genou sur l’évolution clinique postopératoire d’une chirurgie du ligament croisé antérieur chez le sportif

Objectives

To establish the influence of the type of brace on the postoperative clinical evolution after anterior cruciate ligament (ACL) surgery in competitive sportspeople.

Methods

The authors prospectively followed the evolution of three populations of ACL reconstruction: one who received a functional brace, the other a rigid brace and last no brace. The three groups followed the same rehabilitation program. The clinical parameters of evaluation were pain, perimeter patellar joint, range of motion, muscular atrophy, locking the quadriceps, and the quality of walking. We also used the IKDC subjective Knee Evaluation Form and PPLP scoring scale.

Results

There is no clinically significant difference at about a month of surgery between the three groups (407 patients). There is no difference with the PPLP scoring scale. No repeat rupture is occurred postoperatively. There is a significant difference in the IKDC subjective (P = 0.03) between the group with functional brace and rigid brace.

Conclusion

With the same active rehabilitation program, the clinical evolution is identical with or without brace. The only difference is subjective (IKDC subjective Knee Evaluation Form).     

Aspect quantitatif et qualitatif de la traumatologie du sport dans les services d’accueil et d’urgence

The purpose of this article is to report a qualitative and quantitative analysis of sports trauma activity in emergency units in France. A prospective survey was conducted in four emergency units and included 598 cases of sports trauma, which accounted for 17% of the trauma activity. Emergency room physicians thus play an essential role in care for sports trauma victims in France. Diagnosis of the severity of the injury is essential in sports trauma, particularly when the knee is involved. A prospective analysis of two prospective series showed that triage in the emergency room could be perfected. This leads to discuss the importance of training emergency physicians in sports trauma.     

Fixation des reconstructions du ligament croisé antérieur aux ischiojambiers par un « crosspin » unique (étude biomécanique)

Introduction

Postoperative reeducation and the retaking of precocious activities after the reconstruction of the anterior cruciate ligament (ACL) require a primary fixation to the adequate mechanic characteristics. The aim of the study is to determine the fixation properties with a unique RigidFix^® crosspin of the tendinous transplants in tiny diameter tunnels simulating a double bundle reconstruction.

Material and methods

On six adult fresh frozen cadavers (12 femurs and 12 tibias dissected), 48 bone tunnels were prepared in which were fixed with a single “crosspin” RigidFix^® a tendon with adequate diameter to tunnels (5, 6, 7 and 8 mm). Two types of tests were performed: cyclic test (sinusoidal load between 50 N and 150 N for 500 cycles) and ultimate load test (increasing load with a controlled speed 5 mm/min).

Results

The mean lengthening after 500 cycles was 1,89 ± 0,84 mm. The yield load was 262 ± 60 N with a lengthening of 4,61 ± 1,68 mm. The stiffness of the whole mounting was 61 ± 16 N/mm and the max load is 295 ± 79 N. The resistances (yield load and max load) were more important in the femur than in the tibia.

Discussion

The stress supported by the femoral fixation is less important than the tibia, in view of the application angle when the knee is extended. The yield load result fulfilled the specifications in the femur. At the tibia, the ultimate strength is not enough to allow intensive rehabilitation.

Conclusion

The use of a single “crosspin” in an anatomic reconstruction of anterior cruciate ligament is possible at the femur with diameters of the transplant greater than or equal to 6 mm, but not desirable in the tibia.     

Reconstruction du LCA chez le sportif de compétition. Évaluation, à court terme,après reprise du sport

Background

Most studies have observed satisfactory outcome after anterior cruciate ligament (ACL) reconstruction. The best series report 80 to 90% success, irrespective of the type of operation. The purpose of this work was to investigate resumption of sports activities after ACL reconstruction. We studied the impact of the conditions of sports activity after the operation, gender, type of sport, presence of an extra-articular reinforcement and time since surgery.

Material and method

In order to search for significant differences between the postoperative and follow-up scores, a questionnaire with a subjective IKDC grid was addressed 12 months after their hospitalization to all athletes who had undergone ACL reconstruction at the CERS from 1^st January, 2003 through 31^st October, 2004.

Results

For the period considered, 2248 athletes were hospitalized at the CERS for ACL reconstruction. The response rate was 43% (969 responses at 12 months). There was no significant difference between the hospitalized population and the responders in terms of type of sports activity or type of graft. There was however a significant female predominance among responders (p = 0.01). Mean follow-up was 13.9 ± 2.9 months. Reconstruction methods were: hamstring graft 54%, free patellar graft 43%, MacIntosh fascia lata 2%, MacIntosh quadriceps 1%. The main activity was a pivot sport for 74% of the athletes. Male gender predominated: 77%. There was no difference regarding postoperative training, but competition level was achieved more readily by males (65% versus 54%, p = 0.0038), since more females stated resumption of competition was not an objective. It was also noted that resumption of training occurred earlier for gliding sports than for pivot–contact sports (7.32 ± 2.09 months versus 8.23 ± 2.66 months, p = 0.021). The presence of a lateral reinforcement did not have a significant impact on resumption of sports activities which was more frequent in the hamstring group than the patellar group (16% versus 7%, p < 0.0001) and more frequent in the pivot–contact sports (p = 0.0039). Regarding the role of the surgical technique, resumption of training and competition was better after hamstring plasty compared with patellar tendon plasty for follow-up less than or equal to 12 months (p = 0.0009 and 0.0001 respectively). The subjective IKDC score was also significantly better in the hamstring group for the period considered (p = 0.0006). The differences observed early in the follow-up resolved over time and no significant difference was observed at 18 and 22 months. Regarding the MacIntosh fascia lata plasty, resumption of competition was significantly earlier (7.67 ± 1.87 months) compared with hamstring plasty (9.69 ± 2.58 months) and patellar tendon plasty (9.65 ± 3 months). Resumption of training (90%) and competition (76%) was also better with the MacIntosh fascia lata plasty compared with the two other techniques but the difference was not significant. These differences, in favor of the MacIntosh fascia lata plasty, might have been due to a recruitment bias since the level of the sports activities was significantly higher in the MacIntosh population than in the populations of the other two methods.

Conclusion

This study is of particular interest because of the size of the homogeneous study population resulting from the highly selective recruitment of athletes at the CERS. This study is generally in agreement with prior data in the literature, particularly concerning the rate of resumed training one year after surgery. This study shows that the patellar tendon plasty reaches maturity more slowly than the hamstring plasty although the two techniques yielded comparable results at 18 months for all criteria studied.     

Influence des facteurs intrinsèques anatomiques dans la rupture du ligament croisé antérieur : étude anatomoradiologique comparative

Studies of knee-joint anatomy and biomechanics have demonstrated to main intrinsic factor shaving a negative impact on the anterior-cruciate ligament (ACL): a narrow intercondylar notch and a weak tibial slope. The purpose of this work was to study tibial slope and width of the intercondylar notch measured on plain X-rays and magnetic resonance imaging (MRI) in knees with and without ACL tears.     

Intérêt du Télos dans l'évaluation de la laxité chronique antérieure du genou en pré- et en postopératoire

The objective of our work is to clarify the contribution of knee arthrometer in the diagnosis of the anterior laxity of the knee, to look for the factors of escalation of this pathology, to estimate the objective results and outcomes following of the anterior cruciate ligament surgery. It is about a retrospective study which concerned 78 patients presenting the anterior chronic laxity of the knee, investigated, treated and followed in the M.-T.-Kassab Institute of Orthopaedics over a period of 10 years. The average age of our patients was of 27.6 years with a male ascendancy. The anterior cruciate ligament surgery was realized according to the technique of Kenneth-Jones under arthroscopy. The arthrometer has been used to determine the outcome 6 months after the surgery. Before the surgery, the average anterior translation of the tibia was 15.3 mm, 95% of the patients had 8 mm previous absolute laxity, while the differential was about 4 mm in 87% of the cases in which comparative study could be made. There was a statistically significant correlation between the Lachman's test, the internal meniscus injuries and the delay accident — surgery with the anterior knee laxity in the arthrometer. The postoperative average laxity was bout 8.2 mm and earning was proportional to the importance of the initial tibial translation. The present study demonstrates that arthrometer tests may be an objective complement for the clinical exam, with a diagnostic, previous and therapeutic purpose.     

Rupture du LCA : cas de l’athlète féminine

Female athletes have 2–3 times more risks of ACL injury than male. Hormonal, anatomical and neuromuscular factors would explain this female predisposition. Prevention training, aimed to avoid “dynamic” valgus, leads to a reduction of ACL injury risks. These programs, including a neuromuscular training, improve knee dynamic control in female athletes and decrease the loadings on the ACL. The aim of this review is to make an inventory of the knowledge on this subject by analyzing theses predispositions and most specially the influence of the neuromuscular factors. Therefore, the purpose is to make a comparative assessment of the various prevention programs to determine the essential elements for an effective intervention of the physiotherapist.     

Les ruptures du tendon du muscle tibial antérieur

In sports medicine, tears of the tibialis anterior are exceptional. We describe our experience with one case. Two types of injury can be observed: true tears involving the main body of the muscle under the pulley or the more distal portion at the insertion and fissurations. These injuries usually occur in a context of longstanding tenosynovitis or tendinopathy and are generally observed in runners. The mechanism requires stretching with the foot in forced plantar flexion and external rotation (fall backward with forefoot blocked). The diagnosis is clinical. Complementary explorations, excepting plain X-rays to search for a distal detachment from the bone, are not indispensable. In sports medicine, surgical treatment is required for full thickness tears. A plasty is usually performed with the third toe extensor. Recovery is long and progressive. In our experience, corticosteroid injections do not provoke these tears but can be useful for more rapid recovery in the athlete. After an injection, we immobilize the ankle for three weeks in a walking cast in order to “limit” the motivated athlete.     

Laxité chronique antérieure du genou chez le sportif. À propos de 118 cas

The chronic anterior laxity of the knee is an evolutive disease owing to a rupture of the anterior crossed ligament which engages the functional prognosis of the lower member and compromise sportive activity. Many techniques of ligamentous plasty were described. Our study is about 118 sportsmen suffering from chronic anterior laxity treated by the modified Kenneth-Jones procedure between 1998 and 2002. After a main following-up of 25 months, we tried to value our results and determine the real place of ligamentous plasty using patellar tendon in the treatment of sportsmen chronic anterior laxity.
