ABSTRACT
PURPOSE: The main objective of this retrospective study was to establish an epidemiological overview of patients admitted to an Emergency department specialized in musculo-skeletal trauma for acute lesions related to Badminton practice in the period from January 1st 2010 to January 1st 2015. METHODS: There were 135 patients with 140 admissions and 146 total number of injuries. There were 67 females (48%) and 73 males (52%). The mean age was 28 ± 13.8 years, ranging 10-66 years. 91 patients (65%) could be contacted by telephone to fill a questionnaire aimed at completing the information provided by the medical records. RESULTS: 129 lesions (88.3%) were located to the lower limbs, 16 (11%) to the upper limbs, and one (0.7%) at the head. For the whole series, there were 89 sprains (60.9%), 32 tendino-muscular lesions (21.9%), 13 fractures (8.9%), 5 dislocations (3.4%), 3 painful contusions (2.1%), 3 meniscal injuries (2.1%) and one wound (0.7%). In the lower limbs, lateral ankle sprain was the most frequent diagnosis (43.4%), followed successively by rupture of the Achilles tendon (13.9%), tennis leg (8.5%), and mid-foot sprain (6.9%). Of the 146 lesions, 117 (80.1%) received non-operative treatment, 28 (19.1%) received surgical treatment in the operation room, and one simple wound (0.7%) was sutured in the emergency room. CONCLUSIONS: Lateral ankle sprains followed by tendino-muscular lesions of the calf are by far the most frequent lesions of badminton. Modification of the shoes of badminton players should be considered to decrease the high incidence of ankle injuries.

INTRODUCTION: The primary objective of this study was to compare the radiological and clinical results of anterograde and retrograde screwing in subtalar arthrodesis using a single compression screw. The secondary objective was to evaluate the subjective results and consolidation of this procedure. The hypotheses were that isolated screw fixation was sufficient to achieve good consolidation and that there was no difference between the two techniques with a similar rate of bone fusion. METHODS: This is a monocentric, retrospective, radio-clinical study based on 99 patients (101 feet), 58 males and 41 females, with an average age of 64 years. The main aetiology was post-traumatic osteoarthritis, which represented 51% of cases. Two groups were formed: group A (52 feet) consisting of fixed arthrodesis with ascending (retrograde) screwing and group D (49 feet) consisting of fixed arthrodesis with descending (anterograde) screwing. The two groups were statistically comparable in terms of demographic data as well as aetiologies and comorbidities. Arthrodeses which were not fused at 6 months were reassessed at one year and in the event of any radio-clinical doubt regarding consolidation, an additional CT scan was prescribed. Average post-operative follow-up was 11 ± 5 years (2-27 years). RESULTS: Ninety-two arthrodeses (93%) were fused at one year and 9 were considered to be in non-union, 5 (9.8%) in group A, and 4 (8.3%) in group D. We recorded 30 complications, 22 of which were due to a conflict with the screw head, 18 (34.5%) in group A and 4 (8.3%) in group D (p = 0.03). Conflict between the screw head and the heel led to the removal of the screw after consolidation of the arthrodesis. The clinical results were evaluated using Odom's criteria. Nine per cent of patients described their results as excellent, 29% as good, 51% as satisfactory and 11% found the result to be poor. CONCLUSION: The fusion rate for isolated compression screw arthrodesis is good, and there is no difference between anterograde and retrograde screws. However, the discomfort caused by the screw head being insufficiently embedded in the retrograde group led to a non-negligible number of additional surgeries to remove the screw.

Acetabulum malunions are extremely difficult to treat, and for many years, surgical indications have been dominated by total hip replacement. We treated a protruding acetabular malunion, 20 years ago, using an intra-articular buttress, by means of an allograft corresponding to a femoral head fragment which had been cryopreserved. The radiological and clinical result with this extended follow-up is quite remarkable, which has motivated us to present this original technique.
ABSTRACT
PURPOSE: The aim of this study was to compare clinical and laximetric results in chronic, isolated posterior cruciate ligament (PCL) rupture repairs, using either a hamstring graft or an artificial ligament (ligament advanced reinforcement system (LARS®)). METHODS: Sixteen patients presenting with an isolated unilateral PCL rupture were included in this retrospective study. Initially, eight underwent a PCL reconstruction using a hamstring tendon autograft (hamstring group), and over a later period, eight further patients underwent a reconstruction using an artificial ligament with a new procedure. RESULTS: Fifteen patients were male and one female, with an average age of 29.3 years. All patients were operated on within an average time of 18 months post-injury. Pre-operative posterior laxity was equivalent (p = 0.309), 18.25 mm on average for the hamstring group and 18.75 mm for the LARS group. With an average follow-up of 24 months, residual posterior laxity was significantly improved, decreasing from 18.25 to 7.37 mm for the hamstring group (p < 0.05) with a median at 7.5 mm and from 18.75 to 5.25 mm for the LARS group (p < 0.05) with a median at 5 mm. The improvement in laxity for the hamstring group was 60% and 71.5% for the LARS group. The LARS group compares favourably (p = 0.003 and 0.01). Tegner activity level improved significantly following ligamentoplasty, with no difference between the two groups (p = 0.4). Likewise, there was no significant difference in the Lysholm and IKDC scores between the two groups (p = 0.4). CONCLUSION: The initial hypothesis of this study was proven correct. Nevertheless, a longer term study is necessary to assess the consequences of residual laxity in hamstring grafts and the long-term behaviour and tolerance of the LARS artificial ligament.

INTRODUCTION: The aim of this study was to assess the differential laxity after reconstruction of the anterior cruciate ligament (ACL) by the TLS® technique using a single tendon, the semitendinosus in four-strand graft, compared with the hamstring technique which uses both the gracilis and semitendinosus. We hypothesised that this surgical technique would provide post-surgical differential laxity measurements at least as good as those of the hamstring technique. MATERIALS AND METHODS: We carried out a prospective monocentric study on patients undergoing unilateral anterior cruciate ligament repair between December 2014 and June 2016. All patients were followed up for at least 12 months. The series compares 61 patients operated on using the TLS® technique by the same surgeon, with 33 patients operated on using the hamstring technique by a second surgeon. The main objective of the study was to compare the post-operative differential laxity, measured using the KT1000, between the two techniques. RESULTS: There was no significant difference in the patients' epidemiological characteristics and pre-operative scores between the two groups. Average pre-operative differential laxity was 6.5 mm ± 2.1 (min 3; max 12) in the TLS group and 6.4 mm ± 2.0 (min 0; max 11) in the hamstring group, with no statistically significant difference. The average post-operative difference in laxity was - 0.1 mm ± 1.9 (min - 5; max 4) in the TLS group and 0.3 mm ± 2.0 (min - 7; max 5) in the hamstring group. Again, no significant difference was observed between groups. DISCUSSION: This study demonstrates a level of post-operative differential laxity control using TLS comparable with that of the ACL reconstruction technique using a hamstring graft with preserved tibial insertion. LEVEL OF EVIDENCE: II, prospective cohort study.

INTRODUCTION: Damage to the common peroneal nerve is the most frequent nerve injury in lower limb traumas. Our objective was to assess the motor and sensory recovery levels and the functional outcomes after remedial surgery for common peroneal nerve trauma, through either neurolysis, direct suture or nerve graft. METHODS: This is a transversal, observational study of a monocentric cohort of 20 patients who underwent surgery between January 2004 and June 2016, which included 16 men and 4 women whose median age was 35 ± 11 years. We assessed the level of sensory and motor nerve recovery and the Kitaoka score. Nine patients benefited from neurolysis, 5 had direct sutures, and 6 received a nerve graft. RESULTS: With 48 months' average follow-up, 7 out of 9 patients underwent neurolysis and 4 out of 5 with direct sutures had good motor recovery (≥ M4), but none for the grafts. Sensory recovery (≥ S3) was satisfactory in 7 out of 9 cases in the neurolysis group, 3 out of 5 in the direct suture group, and 3 out of 6 in the nerve graft group. The average Kitaoka score was 83.7 ± 11.5 for the neurolysis group, 86.8 ± 16 for the direct suture group, and 73 ± 14 for the graft group. CONCLUSION: Surgical treatment by neurolysis and direct suture yields good results with a motor recovery ratio nearing 80%. When a nerve graft becomes necessary, recovery is poor and resorting to palliative techniques in the shorter run is a strategy which should be evaluated.

In complex fractures of the proximal tibial metaphysis and epiphysis, possible adverse outcomes after internal fixation include not only joint surface incongruity, but also lower limb malalignment requiring revision surgery. Navigation has been proven effective for the intraoperative control of lower limb alignment during osteotomy and knee arthroplasty. In complex traumatic fractures, temporary fixation by a locking screw plate allows sensor positioning followed by navigation maneuvers to adjust lower limb alignment. If malalignment is found, the construct can be modified economically by altering the diaphyseal fixation without modifying the metaphyseal screws. The objective of this study was to describe the use of navigation in three patients who required internal fixation of tibial-plateau fractures.

BACKGROUND: A careful analysis of the reasons for ACL reconstruction failure is essential to selection of the optimal surgical revision technique designed to ensure good rotational stability and to minimise the risk of re-rupture. OBJECTIVE: To evaluate anterolateral ligament (ALL) stabilisation during revision ACL reconstruction. HYPOTHESIS: ALL stabilisation during revision ACL reconstruction provides good rotational stability without increasing the risk of complications. MATERIAL AND METHODS: This multicentre study included 349 patients, 151 retrospectively and 198 prospectively. There were 283 males and 66 females. Inclusion criteria were an indication for revision ACL reconstruction surgery with combined intra-articular reconstruction and ALL stabilisation after failed autograft ACL reconstruction, and intact PCL. Exclusion criteria were primary ACL reconstruction and concomitant peripheral medial and/or lateral lesions. Each patient underwent a clinical and radiographic evaluation before and after revision surgery. Before revision surgery, the mean IKDC score was 56.5±15.5 and 96% of patients were IKDC C or D. RESULTS: Rates were 5.0% for early and 10.5% for late postoperative complications. Lachmann's test had a hard stop at last follow-up in 97% of patients. The pivot-shift test was positive in 1% of patients. The mean subjective IKDC score was 84.5±13.0 and 86.5% of patients were IKDC A or B. The proportions of patients with radiographic knee osteoarthritis at last follow-up was unchanged for the lateral tibio-femoral and patello-femoral compartments but increased by 9.7% to 21.2% for the medial tibio-femoral compartment. The re-rupture rate was 1.2% and the further surgical revision rate was 5.4%. CONCLUSION: Anterior laxity at last follow-up was consistent with previous studies of revision ACL reconstruction. However, rotational stability and the re-rupture risk were improved. ALL stabilisation is among the techniques that deserve consideration as part of the therapeutic options for revision ACL reconstruction. LEVEL OF EVIDENCE: IV, retrospective and prospective cohort study.

INTRODUCTION: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications. The study hypothesis was that associating ALL reconstruction to ACL reconstruction does not increase the complications rate found with isolated ACL reconstruction. MATERIAL AND METHODS: A prospective multicenter study included 392 patients: 70% male; mean age, 29.9 years; treated by associated ACL and LT reconstruction. All adverse events were inventoried. RESULTS: Mean hospital stay was 2 days, with 46% day-surgery. Walking was resumed at a mean 27 days, with an advantage for patients treated by the hamstring technique. The early postoperative complications rate was 12%, with 1.7% specifically implicating LT reconstruction: pain, hematoma, stiffness in flexion and extension, and infection. There was a 5% rate of surgical revision during the first year, predominantly comprising arthrolysis for extension deficit. The 1-year recurrence rate was 2.8%. DISCUSSION: The complications rate for combined intra- and extra-articular reconstruction was no higher than for isolated intra-articular ACL reconstruction, with no increase in infection or stiffness rates. The rate of complications specific to ALL reconstruction was low, at 1.7%, and mainly involved fixation error causing lateral soft-tissue impingement. LEVEL OF EVIDENCE: IV, prospective multicenter study.

INTRODUCTION: During anterior cruciate ligament (ACL) reconstruction procedures, anterolateral reconstruction (ALR) can also be performed to improve the knee's rotational stability. However, the effectiveness of this supplemental technique and its impact on the risk of retears and on the onset of secondary degenerative changesare controversial. HYPOTHESIS: ALR improves control over the pivot shift, reduces the retear risk and delays the appearance of secondary degenerative lesions. MATERIAL AND METHODS: Clinical examination, knee laxity measurements and X-ray evaluations were done in 478 patients with more than 3years' follow-up after combined ACL and ALR from 11 participating hospitals. The mean patient age at the time of surgery was 28years. Eighty-eight percent of the patients participated in pivot sports and 45% were competitive athletes. The findings of this study were compared to historical isolated ACL reconstruction data. RESULTS: The average follow-up was 6.8years. No detectable pivot shift was found in 83% of patients, while 12.8% of patient had a smooth glide. The side-to-side difference in anteroposterior knee laxity with maximum manual force was less than 3mm in 66% of patients and less than 5mm in 95%. The retear rate was 5.4%, with half of these patients undergoing revision ACL surgery. Secondary meniscus damage requiring surgery occurred in 6.3% of patients; the radiological osteoarthritis rate was 17.5%. DISCUSSION: When compared to historical ACL reconstruction data, combined intra- and extra-articular reconstruction does not increase the complication rate. At a mean follow-up of 6.8years, it provides better control over the pivot shift along with a low retear rate and low occurrence of secondary meniscus injuries. LEVEL OF EVIDENCE: IV, multicenter study.

AIMS: The role of high tibial osteotomy (HTO) is being questioned by the use of unicompartmental knee arthroplasty (UKA) in the treatment of medial compartment femorotibial osteoarthritis. Our aim was to compare the outcomes of revision HTO or UKA to a total knee arthroplasty (TKA) using computer-assisted surgery in matched groups of patients. PATIENTS AND METHODS: We conducted a retrospective study to compare the clinical and radiological outcome of patients who underwent revision of a HTO to a TKA (group 1) with those who underwent revision of a medial UKA to a TKA (group 2). All revision procedures were performed using computer-assisted surgery. We extracted these groups of patients from our database. They were matched by age, gender, body mass index, follow-up and pre-operative functional score. The outcomes included the Knee Society Scores (KSS), radiological outcomes and the rate of further revision. RESULTS: There were 20 knees in 20 patients in each group. The mean follow-up was 4.1 years (2 to 18.7). The mean total KSS at last follow-up was 185.7 (standard deviation (sd) 5) in group 1 compared with 176.5 (sd 11) for group 2 (p = 0.003). The mean hip-knee-ankle angle was 180.2° (sd 3.2°) in group 1 and 179.0° (sd 2.2°) in group 2. No revision was required. CONCLUSION: We found that good functional and radiological outcomes followed revision of both HTO and UKA to TKA. Revision of HTO showed significantly better functional outcomes. These results need to be further investigated by a prospective randomised controlled trial involving a larger group of patients. Cite this article: Bone Joint J 2016;98-B:1620-4.

INTRODUCTION: No objective criteria exist to help surgeons choose between IM nailing and plate fixation for 4-part fractures of the proximal humerus. The goal of this study was to identify radiological criteria that would make one technique a better choice than the other. MATERIAL AND METHODS: This was a comparative, multicentre, retrospective study of 54 cases of antegrade nailing and 53 cases of plating performed between 1st January 2009 and 31 December 2011 for 4-part fractures of the proximal humerus. All patients had a minimum radiological and clinical follow-up of 18 months. The functional outcomes were evaluated using the weighted Constant score; a poor result was defined as a weighted Constant score<70%. The following radiological criteria were evaluated during the preoperative assessment and at the last follow-up: initial displacement and reduction of humeral head and tuberosities; morphology of the medial column (i.e. calcar comminution, posteromedial hinge, size of metaphyseal head extension); occurrence of avascular necrosis (AVN). RESULTS: After an average follow-up of 42 months, the weighted Constant scores and rate of poor outcomes were 77% and 48% in the nail group and 81% and 38% in the plate group, respectively (ns). The humeral head was reduced into an anatomical position, valgus or varus in 57%, 30% and 13% of cases in the nail group, and 58%, 29% and 13% in the plate group, respectively. The tuberosities healed in an anatomical position in 72% of nail cases and 70% of plate cases (ns). Only the presence of a medial hinge preoperatively had an effect on the functional outcomes in the nail and plate groups: the weighted Constant scores (P=0.05) and rate of poor outcomes (P=0.02) were 82% and 52% in the nail group and 97% and 9% in the plate group, respectively. The complication rates were comparable: the rates of AVN and articular screw penetration were 17% and 11% in the nail group, and 15% and 11% in the plate group, respectively. The surgical revision rate was 18.5% in the nail group and 30% in the plate group. CONCLUSION: If the medial hinge is preserved, we recommend locking plate fixation. In other cases, either technique can be used as long as the general rules of internal fixation are applied: reduction of the tuberosities, varus correction and stabilization of the calcar area.

PURPOSE: The goal of this article is to present our experience on navigation for osteotomies around the knee and especially osteotomies for coronal deformities. The first computer-assisted osteotomy was performed in March 2001 and since that time more than 1000 osteotomies have been performed in our department. METHODS: All the osteotomies were performed with the Orthopilot® device (B-Braun-Aesculap, Tuttlingen, Germany). The main indication was for genu varum deformities but several cases were operated for genu valgum. The surgical procedure as well as the indications and the rationale for each osteotomy (high tibial osteotomy-HTO, double-level osteotomy-DLO, femoral osteotomy-FO) are addressed in the article. RESULTS: The results are focused on several papers published by the authors since more than 10 years. Regarding HTO for genu varum, the preoperative goal (HKA angle: 184° ± 2°) was reached in 96 % of cases and the difference was statistically significant compared to the non-navigated series (71 %: p < 0.05). Regarding DLO for genu varum, the preoperative goal was reached in 92.7 % for the HKA angle and in 88.1 % for the medial proximal tibial mechanical angle (MPTMA). Regarding genu valgum deformity, the preoperative goal was achieved in 86.2 % of cases for the HKA angle and 100 % of cases for the MPTMA. CONCLUSION: According to these results, one can say that, regardless the type of osteotomy, the procedure is reliable, reproducible and accurate. Since 15 years, all the osteotomies around the knee are navigated in our department. Provided that one uses a reproducible radiograph protocol, navigation allows to perform double-level osteotomies, both for genu varum and genu valgum, with optimal accuracy in order to avoid oblique joint line, which will be difficult to revise to TKA.

INTRODUCTION: In cases of chronic anterior laxity, reconstruction of the anterior cruciate ligament (ACL) can slow the development of osteoarthritis. This study was conducted to determine the overall prevalence of osteoarthritis and to identify the risk factors after ACL reconstruction. HYPOTHESIS: Meniscus tears, time from injury to surgery, body mass index (BMI), residual laxity, and cartilage lesions influence the progression towards osteoarthritis. MATERIALS AND METHODS: This multicenter, retrospective study on the outcome of cruciate ligaments at 12 years of follow-up was conducted within the 2014 SOFCOT Symposium. The cohort included 675 arthroscopic reconstructions of the ACL from January 2002 to December 2003. The clinical evaluation included the objective and subjective IKDC score. Osteoarthritis was analyzed on 589 knee X-rays according to the IKDC classification. The predictive factors of osteoarthritis development studied were age, gender, BMI, time from injury to surgery, activity level, medial or lateral meniscectomy, type of graft, medial or lateral chondropathy, tunnel positioning, and residual laxity. Univariate and multivariate analyses with logistic regression were performed. RESULTS: The mean follow-up was 11.9±0.8 years. The subjective IKDC score was 83.7±13. At 12 years, the rate of moderate to severe osteoarthritis l (IKDCC or D) was 19% (16% medial tibiofemoral osteoarthritis, 4% lateral tibiofemoral osteoarthritis, and 2% patellofemoral osteoarthritis). The prognostic factors were age at surgery greater than 34 years (P<0.05), cartilage lesions at surgery (P<0.05), medial or lateral meniscectomy (P<0.05), and residual laxity (P<0.05). CONCLUSIONS: This large-scale study identified risk factors for osteoarthritis that should improve the information provided to patients on long-term progression after ACL reconstruction. LEVEL OF EVIDENCE: Retrospective cohort study, level IV.

BACKGROUND: Our objective was to evaluate the long-term functional and radiological outcomes of tension band wiring with a single K-wire for acute Rockwood types IV and V acromio-clavicular dislocation (ACD). METHODS: Single-centre cross-sectional non-randomised observational cohort study of 25 shoulders treated surgically between January 2002 and December 2004, in 25 patients, 23 males and 2 females, with a mean age of 35±11years (24-46). The evaluation criteria were the absolute and weighted Constant scores, QuickDASH score, subjective shoulder value (SSV), visual analogue scale (VAS) pain score at rest and during activities, and radiographic features in clinically symptomatic patients. RESULTS: Mean values were as follows: follow-up, 150±17months (133-167); absolute Constant score, 88±17 (71-105); weighted Constant score, 92.5±12.5 (80-105); QuickDASH, 15.5±7 (8.5-22.5); SSV, 88±17% (71-105); VAS pain score at rest, 0.2±0.7 (0-0.9); and VAS pain score while active, 1.4±2.3 (0-3.7). The weighted Constant score was less than 70% in only 8% of patients. Of the 17 patients for whom radiographs were obtained, 8 had acromio-clavicular osteoarthritis. Mean coraco-clavicular distance was 12.3±4.3mm (8-16.6) and mean acromio-clavicular distance was 5±5mm (0-10). The recurrence rate was 8%. CONCLUSION: Tension band wiring with a single K-wire for acute acromio-clavicular dislocation reliably provides good long-term functional outcomes. Recurrences are uncommon and few patients experience symptoms (8%). LEVEL OF EVIDENCE: IV, retrospective study.

INTRODUCTION: Complex 4-part fractures of the proximal humerus are one of the most difficult fractures to manage. For several years, reverse total arthroplasty (RSA) has been proposed as an alternative to hemiarthroplasty (HA) when internal fixation is insufficient. The goal of this study was to compare the short and intermediate term results of these 2 different types of arthroplasty. MATERIALS AND METHODS: In a retrospective, multicenter study, 57 HA and 41 RSA were reviewed after a follow-up of at least 2 years. The clinical evaluation was based on the absolute and adjusted Constant scores, Simple shoulder value (SSV) and the quick-DASH scores. The radiological assessment included standard radiological tests. RESULTS: After a mean follow-up of 39 months, the RSA group had a significantly higher adjusted Constant score than the HA group (83% vs 73%, respectively P=0.02). However, there was no significant difference in the absolute Constant score, the quick-DASH or the SSV scores. Active anterior elevation was better in the RSA group, while internal rotation was better in the HA group (130° vs 112°, P=0.01; sacrum vs L3, P=0.03). There was no significant difference in external rotation (28° vs 23°, P=0.31). The rate of complications was higher in the HA group than in the RSA group (24% vs 10%, P=0.01). The radiological rate of union of the greater tuberosity was similar in both groups (70%) and scapular notching was found in 23% of the RSA group. CONCLUSION: The short and intermediate term clinical outcomes are better with RSA than with HA. The complication rate is higher with HA. Nevertheless, scapular notching occurred in more than 20% of patients with RSA, suggesting that care should be taken when using this prosthesis in young, active patients.

INTRODUCTION: The reversed shoulder prosthesis is becoming the gold standard for cases of complex fracture of the proximal humerus after 70 years of age. MATERIAL AND METHODS: The French Society of Orthopaedic and Traumatology Surgery (SOFCOT) conducted a prospective and retrospective multicenter study to evaluate the results of the reversed shoulder prosthesis implanted in patients with a four-part fracture in nine centers. In the retrospective study (n=41 patients, 78 years of age, 14% ASA grade 3, 21% associated fractures) and in the prospective study (n=32 patients, 79 years of age, 37% ASA grade 3, 21% associated fractures) evaluation by independent surgeons was conducted to measure the QuickDASH score, the Constant score, the SSV (subjective shoulder value), and complications to correlate these measurements with radiological results. RESULTS: In both studies, use of an autograft (75%) to perform an osteosuture of tuberosities (90%) and no postoperative immobilization (75%) were similar. In the retrospective study at 39 months (range: 24-62 months) of follow-up, the QuickDASH reached 28 (range: 0-59), the Constant scores (raw Constant=57, weighted Constant=83.4%), and SSV 75 (range: 35-100). Complications after the 1st month (7%) were nonunion or ossifications. In the prospective study at 11 months (range: 5-16.5 months) of follow-up, the QuickDASH reached 40 (range: 1-75), the Constant scores 50 (raw Constant) and 74.6% (weighted Constant), and SSV 69 (range: 10-100). Complications after the 1st month (21%) were stiffness and dislocation, with two patients who underwent revision surgery. In both studies, early complications reached 6% (palsy, dislocation). CONCLUSION: This double (retrospective and prospective) study confirms the good results with a low level of complications of the reversed implant in cases of fracture but with osteosuture of tuberosities.

Evaluer les résultats anatomiques et fonctionnels ainsi que l'incidence de l'arthrose, à 5 ans de recul minimum, d'une technique de plastie mixte intra et extra articulaire aux tendons de la patte d'oie dans les laxités antérieures chroniques du genou. Matériel et méthodes: Cette étude rétrospective a concerné 100 genoux chez 99 patients. Il s'agissait de 22 femmes et 77 hommes, opérés entre novembre 2003 et mars 2006. L'âge moyen était de 29,7+/-10,4 ans et le délai moyen accident/chirurgie de 26,6+/-41,8 mois (2-240). La laxité préopératoire différentielle mesurée à l'aide de l'arthromètre KT 1000 était de 9,2+/-4,4 mm. Les tendons du semi-tendineux et du gracilis étaient laissés pédiculés au tibia et ressortaient du genou, par un tunnel trans condylien latéral, en arrière et en dessous de l'insertion proximale du ligament collatéral latéral. Ils étaient ensuite tendus vers le tubercule de Gerdy et suturés au fascia lata. Résultats: Soixante-huit genoux ont pu être examinés à un recul moyen de 76+/-12 mois. Le tiroir antérieur différentiel moyen au dernier recul était de 2,5+/-3,4 mm (p<0,0001). Soixante-quinze pour cent des patients n'avaient pas de ressaut, 21% avaient un ressaut ébauché et 4% un ressaut franc (p<0,0001). Quatre-vingt-quatre pour cent des patients avaient un score IKDC objectif A ou B. Le score IKDC subjectif moyen était de 90+/-9. Les clichés en schuss ne montraient pas d'aggravation des lésions cartilagineuses (p=0,03). Pour le compartiment fémoro tibial médial, 34% des patients étaient classés stade IKDC A, 50% B, 15% C, 1% D et pour le compartiment latéral 64% stade A, 26% B, 10% C, et 0% stade D. Conclusion: La plastie mixte intra et extra-articulaire à l'aide des tendons de la patte d'oie permet de stabiliser le genou dans le plan sagittal et horizontal avec des résultats anatomiques et fonctionnels satisfaisant à moyen terme. L'évolution vers l'arthrose, au recul moyen terme, est faible de même que l'apparition de lésions méniscales secondaires

INTRODUCTION: Discoid lateral meniscus lesions are relatively rare. The objective of this study was to determine the long-term results of 14 cases of discoid lateral meniscus tears treated by arthroscopic meniscoplasty between July 1991 and May 2009, and to assess the development of osteoarthritis in the lateral compartment. METHODS: The series consisted of 10 patients (14 knees): 3 girls under the age of 15, 3 men and 4 women aged from 16 to 47 years (mean age: 31.4±11.1 years). The main reason for consultation was pain in 10 cases, locking in 2 cases and pain associated with locking in 2 cases. The diagnosis was confirmed preoperatively by MRI in 10 cases, CT-arthrography in 1 case and arthrography in 3 cases. The indication for surgery was made because of a symptomatic discoid lateral meniscus. All cases were treated by arthroscopic meniscal reshaping. Functional results were evaluated using the Lysholm-Tegner, IKDC, KOOS and satisfaction scores. Radiological results were evaluated based on the modified Alhbäck classification for osteoarthritic (OA) changes. RESULTS: No complications were found. Two patients were lost to follow-up. The remaining eight patients (12 knees) were reviewed at a mean of 157.5±72.1 months (61-276). The mean Lysholm-Tegner score was 88.9±10.6 points (67-100), the mean KOOS was 92.4±9.5 (65-100) and the mean IKDC score was 85.4±16.5 points (65-100). All eight of the reviewed patients were satisfied or very satisfied with the result. Radiological analysis found that five knees had no signs of OA, five knees had stage 1, one had stage 2 and one had stage 3. At last follow-up, no patient had been reoperated. CONCLUSION: Meniscoplasty of discoid lateral meniscus tears leads to excellent long-term functional results despite signs of osteoarthritic changes in the lateral compartment of the knee. LEVEL OF EVIDENCE: IV (retrospective study).

INTRODUCTION: The causes of failure of anterior cruciate ligament (ACL) reconstruction mainly involve incorrect tunnel positioning. There is no intraoperative tool allowing the surgeon to test graft biomechanics and to confirm that the new graft is in an optimal position. HYPOTHESIS: Control is improved with computer assisted navigation. MATERIAL AND METHODS: In this retrospective study, revision ACL reconstruction was performed with a new autologous graft in a continuous series of 52 failed ACL reconstructions. A computer assisted navigation system was used intraoperatively in all knees. Evaluation with this system confirmed the position of old and new tunnels as well as intraoperative laxity. RESULTS: Evaluation of tunnel position based on traditional radiological criteria found in the literature significantly underestimated graft biomechanics: 69% of the cases presented with unfavorable graft ansiometry (mean: 13 ± 2.2mm) while the correct position of the tibial tunnel was identified in 64% of cases on radiography and the femoral tunnel in 48%. All new grafts were optimally positioned by the computer assisted navigation system with a mean isometery of 3.2 (± 0.7) mm. Comparative pre- and postoperative evaluation of laxity showed a statistically significant improvement (P < 0.001): preoperative and postoperative Lachman test: 10.5 ± 2 mm and 3 ± 0.5, respectively; global rotational laxity: 24 ± 5° and 37 ± 7° respectively. CONCLUSION: The use of a computer assisted navigation system allows optimal positioning of the graft as well as a predictive assessment of laxity.
