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.     

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.     

Agénésie du ligament croisé antérieur et du ligament croisé postérieur du genou

This case report is an agenesia of the anterior and posterior cruciate ligament of the knee on a young man 35 year old. This malformation is rare and exceptional. The clinic is principally a knee laxity. On the plains radiographics, the diagnostic can be made because there is a hypoplasia or an agenesia of the tibial eminence and a malformation of the femoral intercondylar notch. MRI confirms the diagnostic.     

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.     

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.     

Étude laxométrique après reconstruction du ligament croisé antérieur du genou

We made a follow-up at three, six and 12 months after 148 ACL reconstructions; 53% of the patients had an intensive rehabilitation of four weeks in the center during two months after surgery (including isokinetic and nonisokinetic reinforcement). On KT 2000 arthrometer, laxity and compliance are greater on the operated side. Laxity increases from three to six months but remains stable from six to 12 months after the plasty. After meniscal repair, laxity tends to be greater. Intensive rehabilitation in the center does not increase the laxity but when the resumption of the pivot athletic activities is too precocious, laxity is most frequently pathological. When isokinetic ratios are pathological, shears tend to be more frequently greater but multivariate analysis does not find correlation between functional (ARPEGE), isokinetic or laxometric data.     

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.     

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.     

Rééducation accélérée après ligamentoplastie par la technique DIDT par un protocole simple et adapté à chacun

With most procedures of rehabilitation following reconstruction of the anterior cruciate ligament that was treated though the technique of ligamentoplasty using gracilis and semi-tendinous, the hamstring can’t resume activity until four to six weeks after the operation. Comparing the engraftment of post-traumatic muscle damage, the described rehabilitation procedure is an accelerated procedure that uses early eccentric strengthening of the hamstring starting on day 8. This is achieved first by manual resistance until day 21 then on a hamstring chair from day 21 to day 45. The aim of such a treatment is not to resume sporting activity more quickly, but to ensure that the conditions for recovery are optimized. The described treatment also presents some limitations and should therefore be applied with caution so as not to jeopardize the ultimate recovery of the ligament.     

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.     

Évaluation d’un protocole de kinésithérapie ambulatoire pour la prise en charge des coxarthroses et conflits antérieurs fémoro-acétabulaires des sportifs

Introduction

Hip osteoarthritis and femoroacetabular impingement frequently affect sportsmen and are origins of permanent incapacity. The therapic behaviour before surgery step is not yet established. Physiotherapy is often suggested but it is still difficult to prescribe it correctly. The main goal of our study is to show superiority, both in terms of decrease of pain and increase of sportive activity, of the process “PROTOCOX” including both physiotherapy and manual therapy in comparison with a physiotherapy process “CONTROLE”.

Method

Twenty-six sportive patients of the “Institut régional de médecine du sport de Haute Normandie (IRMSHN)” have been included in the study in an 18-month period. Our secondary aims are to show improvement of life quality and range of motion. Several data including HOOS and Lequesne index have been harvested before and after the six sessions and after 3 months.

Results

For patients (n = 11) of the “PROTOCOX” group (P = 0.034), a significant improvement of the HOOS index, mainly on pain (P = 0.04) and allowing an increase of sportive activity (P = 0.007). After 3 months, there was still a transitory improvement allowing an increase of sportive activity for 75% of the patients (n = 8) of the “PROTOCOX” group in comparison of 18.2% for the “CONTROLE” patients.

Conclusion

The “PROTOCOX” process is simple and practicable in liberal sector, and gives benefits in terms of decrease of pain and sportive activity increase with a reduce number of sessions and its transitory efficiency stays at mid term.     

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).     

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.     

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.     

Évaluation à moyen terme d'une intervention type hémi-Castaing dans le traitement de l'instabilité chronique de cheville

Introduction

The purpose of this study is to evaluate the functional and subjective results of hemi-Castaing replacement ankleplasty associated with articular cleaning in the treatment of chronic instability of the ankle.

Material and method

The study is retrospective, monocentric and continuous. Fifty patients (50 ankles) underwent surgery by hemi-Castaing ligamentar ankleplasty associated with articular cleaning. An independent investigator on the basis of a radioclinical examination and an ankle scoring system made the assessment.

Results

After a period of 37 months, 44 patients were seen again. Ninety-one percent of them were satisfied; the average ankle score was 87.5%. Four patients had relapsed, 26 still had pain. Seventy percent had returned to sport activities, 97% had gone back to work. The main complications were: 6 cases of tendinitis (Achilles tendon), 6 algodystrophies, 3 nevromes of the external saphene nerve and 3 dysesthesis of the external side of the foot. No sign of arthrosis was found on the radiological records.

Discussion

The treatment of chronic instability of the ankle by hemi-Castaing ankleplasty associated with articular cleaning is a satisfactory intervention for the surgeon as well as for the patient. It makes possible the recovery of a stable and functional ankle. The pain, however, will not totally disappear, which the patient should be told before the operation. Mastering the tension of the plasty is the main difficulty of this intervention, which may fail, but not necessarily as a result of the plasty's being too loose. The cause for the failure should also be sought in other factors related to the region of this pathology (deltoidian ligament, neurologic trouble, proprioceptive).     

Spinal cord injury in partial Down syndrome

Spinal cord injury is well documented in Down syndrome, and is commonly associated with atlantoaxial instability and ligamentous laxity. A case of partial Down syndrome is presented in which a cervical spine injury resulted in an incomplete quadriplegia. Possible factors leading to increased risk of SCI in partial Down syndrome are ligamentous laxity, atlantoaxial subluxation or odontoid abnormalities, neck inflammatory changes, and age below eight years.     

La rééducation d'emblée des ischiojambiers après chirurgie du DIDT

Introduction

Following knee ligamentoplasty, the task of muscle restoration principally focuses on the hamstrings, which are the only active structure which can protect the graft and prevent detachment. However, specialists generally advise against work on these muscles for a period of 3–6 weeks following semi-tendinosus and gracilis surgery. The hamstrings are thus left resting during this period, which encourages their wasting and tightening.

Objective

Our team, guided by the principles of rehabilitation for muscular problems, has for more than 2 years been strengthening the hamstrings immediately following ligamentoplasty surgery, making use of the semi-tendinous and gracilis. The objective is not only muscle performance and the protection of the graft, but above all encouraging the healing of the semi-tendinous and gracilis in order to align the collagen fibres and improve their mechanical resistance.

Content

It is a single-focus study, continually rolled forward. This protocol was practised on 56 patients, two patients having to withdraw from the programme because of strain problems.

Methodology

During the hospitalisation of the patient, concentric contraction of the knee flexors was engendered using weak resistance operated manually. Later in our rehabilitation centre, our patients exercised in a hamstring « chair », in the eccentric mode below maximum charge, with an increasing load progression. This was done daily up to the sixth week.

Results

Our results, at the 3rd and 6th week post-surgery, showed a favourable change in articular amplitude and pain suffered, with a low rate of complications. Evidence of pain was found in 12.5% of cases (7/56). Of these 7 patients, 2 (3.5%) had incidents involving muscular strain, rendering the interruption of the physiotherapy necessary for more than 3 consecutive days. Isokinetic results carried out at 4.6 ± 0.7 months showed excellent muscular recuperation of the hamstrings with a deficit of 9.6 ± 14% at slow speed and of 6.8 ± 13.1% at fast speed compared with the heterolateral side.

Discussion

The number of painful occurrences in our study, at 12.5%, is lower than the 20% ad higher frequently found in other documented cases. However the definition of these painful occurrences is imprecise. The performance deficit of hamstrings measured by isokinetic tests after 6 months varied between 15 and 20% depending upon the published study. In our study the results at 4.6 months were better (< 10%).

Conclusion

There can no longer be any doubt about the benefits of strengthening the hamstrings in pathologies of an anterior cruciate ligament. Our work has shown that the early strengthening of these muscles is not disadvantageous. On the contrary we believe that our policy promotes the patient's muscular and functional recovery.     

Rupture post-traumatique négligée du retinaculum extensorum à la cheville. À propos d’un cas et revue de la littérature

Post-traumatic ruptures of the retinaculum extensorum (RE) to the ankle is rare and behind a tendinous luxation, of a rope effect, tiredness and weakening or loss of strength. We report the observation of a patient aged 35 practicing full contact for 20 years, victim of a sports accident two years before upon a foot kick in the kicking bag during a training session bringing about a rupture of the RE at the ankle. Imagery (echography and MRI) made sure the clinical exam and to call for the diagnosis of the rupture of the lower band of the retinaculum with subluxation of the tendons of the tibialis anterior and of the extensor hellucis longus. The take in charge consisted of a local plasty of the RE. On the relapse (6 months), the patient is satisfied with the outcome and taking back to his initial sports activity. Through our observation and a review of the literature, we attempt to review the anatomy of the RE to the ankle and to analyze the causes and the consequences of its rupture as well as the usefulness of the imagery in analyzing its anatomic structure. The rupture of the RE is a rare affection mainly affecting sports persons. They can be unseen and may compromise the sports career of athletes. A meticulous clinical exam and targeting imagery as well as an adequate take in charge allow avoiding this unwanted evolution.     

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.
