RESUMEN
BACKGROUND: Impingement of the ilio-psoas tendon on the acetabular component is a cause of pain after total hip arthroplasty (THA). Studies of cup revision for ilio-psoas impingement (IPI) are scarce and limited in size. We therefore conducted a large multicentre retrospective study with the following objectives: to assess the effectiveness of cup replacement in resolving the impingement syndrome, to determine the frequency and nature of complications after cup revision for IPI, and to identify pre-operative factors associated with good outcomes of cup revision for IPI. HYPOTHESIS: Cup revision is effective in resolving the pain due to IPI in selected patients. METHODS: This retrospective multicentre study included 46 patients who underwent cup revision because of IPI. Before the revision, 38 (83%) patients had prominence of the anterior cup rim (mean, 9.9±4.5mm (range, 2-22mm) by radiography and 35 (76%) had cup malposition (anteversion<10° and/or inclination>50°). Mean follow-up was 21months (range, 6months to 6 years) and no patient was lost to follow-up. Outcomes at last follow-up were assessed based on the Oxford Hip Score (OHS), patient satisfaction index, complications, and revisions. RESULTS: At last follow-up, 39 (85%) patients were satisfied with the revision procedure, a significant improvement versus baseline was noted in the OHS (mean, 43±6; range, 25-48; P<0.001), and 41 patients were free of pain during hip flexion (P<0.001 versus baseline). Complications occurred in 3 (6.5%) patients, but only one complication was severe (deep infection). Recurrent groin pain was reported by 4 (8.7%) patients at last follow-up. None of the factors studied predicted the outcome of revision surgery. DISCUSSION: Cup revision for IPI after THA is effective in relieving the groin pain in 80% of patients with anterior cup rim prominence and/or cup malposition. However, complications can occur. Tenotomy may be preferable when the diagnosis is in doubt and/or cup position is acceptable. LEVEL OF EVIDENCE: IV, retrospective observational study.

INTRODUCTION: Impingement between the acetabular component and the iliopsoas tendon is a cause of anterior pain after total hip replacement (THR). Treatment can be non-operative, endoscopic or arthroscopic, or by open revision of the acetabular component. Few studies have assessed these options. The present study hypothesis was that endo/arthroscopic treatment provides rapid pain relief with a low rate of complications. METHODS: A prospective multicenter study included 64 endoscopic or arthroscopic tenotomies for impingement between the acetabular component and the iliopsoas tendon, performed in 8 centers. Mean follow-up was 8months, with a minimum of 6months and no loss to follow-up. Oxford score, patient satisfaction, anterior pain and iliopsoas strength were assessed at last follow-up. Complications and revision procedures were collated. Forty-four percent of patients underwent rehabilitation. RESULTS: At last follow-up, 92% of patients reported pain alleviation. Oxford score, muscle strength and pain in hip flexion showed significant improvement. The complications rate was 3.2%, with complete resolution. Mean hospital stay was 0.8 nights. In 2 cases, arthroscopy revealed metallosis, indicating revision of the acetabular component. The only predictive factor was acetabular projection on oblique view. Rehabilitation significantly improved muscle strength. CONCLUSION: Endoscopic or arthroscopic tenotomy for impingement between the acetabular component and the iliopsoas tendon following THR significantly alleviated anterior pain in more than 92% of cases. The low complications rate makes this the treatment of choice in case of failure of non-operative management. Arthroscopy also reorients diagnosis in case of associated joint pathology. Projection of the acetabular component on preoperative oblique view is the most predictive criterion, guiding treatment.

INTRODUCTION: Dislocation after total hip arthroplasty (THA) is a leading reason for surgical revision. The risk factors for dislocation are controversial, particularly those related to the patient and to the surgical procedure itself. The differences in opinion on the impact of these factors stem from the fact they are often evaluated using retrospective studies or in limited patient populations. This led us to carry out a prospective case-control study on a large population to determine: 1) the risk factors for dislocation after THA, 2) the features of these dislocations, and 3) the contribution of patient-related factors and surgery-related factors. HYPOTHESIS: Risk factors for dislocation related to the patient and procedure can be identified using a large case-control study. PATIENTS AND METHODS: A multicenter, prospective case-control study was performed between January 1 and December 31, 2013. Four patients with stable THAs were matched to each patient with a dislocated THA. This led to 566 primary THA cases being included: 128 unstable, 438 stable. The primary matching factors were sex, age, initial diagnosis, surgical approach, implantation date and type of implants (bearing size, standard or dual-mobility cup). RESULTS: The patients with unstable THAs were 67±12 [37-73]years old on average; there were 61 women (48%) and 67 men (52%). Hip osteoarthritis (OA) was the main reason for the THA procedure in 71% (91/128) of the unstable group. The dislocation was posterior in 84 cases and anterior in 44 cases. The dislocation occurred within 3 months of the primary surgery in 48 cases (38%), 3 to 12 months after in 23 cases (18%), 1 to 5years after in 20 cases (16%), 5 to 10years after in 17 cases (13%) and more than 10years later in 20 cases. The dislocation recurred within 6 months of the initial dislocation in 23 of the 128 cases (18%). The risk factors for instability were a high ASA score with an odds ratio (OR) of 1.93 (95% CI: 1.4-2.6), neurological disability (cognitive, motor or psychiatric disorders) with an OR of 3.9 (95% CI: 2.15-7.1), history of spinal disease (lumbar stenosis, spinal fusion, discectomy, scoliosis and injury sequelae) with an OR of 1.89 (95% CI: 1.0-3.6), unrepaired joint capsule (all approaches) with an OR of 4.1 (95% CI: 2.3-7.37), unrepaired joint capsule (posterior approach) with an OR of 6.0 (95% CI: 2.2-15.9), and cup inclination outside Lewinnek's safe zone (30°-50°) with OR of 2.4 (95% CI: 1.4-4.0). DISCUSSION: This large comparative study isolated important patient-related factors for dislocation that surgeons must be aware of. We also found evidence that implanting the cup in 30° to 50° inclination has a major impact on preventing dislocation. LEVEL OF EVIDENCE: Level III; case-control study.

INTRODUCTION: The rate of iterative arthroscopy has been increasing over the last decade as the technique has grown. The results of and reasons for these revision procedures, however, are not exactly known. We therefore conducted a prospective study to shed light on: 1) functional results and patient satisfaction following repeated arthroscopy, and 2) the relevant indications. HYPOTHESIS: Functional scores and patient satisfaction increase following repeated arthroscopy. MATERIALS AND METHOD: A single-center continuous prospective study without control group included patients undergoing repeated hip arthroscopy between September 2010 and September 2014, with a mean 28months' follow-up (median, 23.3months; range, 12-62months). Preoperative and follow-up functional assessment used the modified Harris hip, WOMAC and Christensen (NHAS) questionnaires, and a satisfaction scale. On etiological analysis, repeated arthroscopy was indicated if a cause of recurrent or persistent pain accessible to arthroscopic treatment was identified. RESULTS: Seventeen patients were included out of 295 primary arthroscopies (5.7%): 9 male, 8 female; median age, 29.6years (range, 16-48years). Indications for primary arthroscopy comprised 13 cases of femoroacetabular impingement, 3 labrum lesions with instability, 1 chondromatosis and 1 case of osteoarthritis. Eleven of the 17 primary lesions showed persistence, including 9 of the 13 cases of femoroacetabular impingement. There were 3 failures in 17 repeated arthroscopies. All functional scores improved, with a gain of 7 points (P<0.06) on modified Harris hip score, 25 points (P<0.0006) on WOMAC score, and 27 points (P<0.001) on NHAS score. Ten of the 17 patients were satisfied or very satisfied with the repeated arthroscopy (59%). CONCLUSION: Although less good than on primary arthroscopy, functional results on repeated hip arthroscopy were satisfactory in the short term. The main reason for repeated arthroscopy was persistence of initial abnormality due to insufficient treatment.

With the development of conservative hip surgery techniques, new entities such as microinstability have been identified. Microinstability is a painful supra-physiological mobility of the hip. It results from the association of architectural and functional abnormalities impairing joint stability. These risk factors concern hip joint bone architecture or peri-articular soft tissues. Bone abnormalities are identified on hip assessment parameters. Soft tissues also play a key role in the static and dynamic stability of the hip: the joint capsule, labrum, ligamentum teres and adjacent myotendinous structures affect joint coaptation; any abnormality or iatrogenic lesion concerning these structures may constitute a risk factor for microinstability. Diagnosis is based on interview, clinical examination and imaging. Findings of labral lesions or femoro-acetabular impingement do not rule out microinstability; they may be associated. Treatment is based first on physiotherapy for muscle reinforcement to improve joint coaptation. In case of failure, arthroscopic surgery is indicated for femoro-acetabular impingement and capsular plicature which is being evaluated. Periacetabular osteotomy or shelf acetabuloplasty may be indicated, according to the severity of joint bone architecture abnormality. Microinstability is a multifactorial entity. Lesions induced by microinstability may in turn become risk factors for aggravation. Diagnosis and indications for surgery are thus difficult to establish. Only full clinical examination and exhaustive imaging assessment allow microinstability and associated lesions to be identified.

INTRODUCTION: Slipped capital femoral epiphysis (SCFE) can lead to hip impingement, more or less rapidly depending on initial slippage severity and on surgical technique. Various surgical options are applicable, including in situ fixation (ISF). The aim of the present study was to look for long-term signs of radiological impingement in hips treated for SCFE by IFS, in order to identify a slip threshold beyond which impingement more regularly appears. MATERIAL AND METHODS: A multicenter retrospective study assessed the clinical and radiological evolution of patients operated on by ISF for SCFE, with a minimum 10 year's follow-up. Coxometric analysis of postoperative and last follow-up radiographs was performed. Functional outcome was assessed on Oxford hip score and radiographic osteoarthritis on the Tönnis classification. Alpha angle was measured on lateral views to highlight hip impingement. RESULTS: Two hundred and twenty-two hips were included, with a mean 11.2 years' follow-up. Mean age at diagnosis was 12.8 years. Mean preoperative Southwick angle was 38.8°, with 43% of hips at stage I, 42% at stage II and 15% at stage III. At latest follow-up, mean Oxford score was 14.86, with 88% of hips rated Tönnis 0 or I. Only 15 cases of impingement were diagnosed. There seemed to be a non-significant trend for hip impingement in SCFE exceeding 35°. CONCLUSION: ISF led to hip impingement in moderate to severe initial epiphyseal displacement. However, in smaller displacement, the consequences were milder, with perfectly satisfactory function scores and no clinical or radiological evidence of impingement. The threshold seemed to be around 35° slippage, beyond which other surgical options than ISF should be considered. Thus, it seems reasonable to propose isolated ISF in SCFE<35° and to treat symptomatic impingement by surgery in stage II slips.

OBJECTIVES: The objective of this study was to investigate cases of femoroacetabular impingement (FAI) and analyze the risk factors for a painful hip at skeletal maturity after Perthes disease. We hypothesized that FAI occurs as a sequela of Perthes disease and that coxa plana and triple osteotomy of the pelvis (TOP) may be risk factors. METHODS: Ninety-five hips were included from 1981 to 2011, 56 of which were operated on with TOP (53) or shelf acetabuloplasty (3). The results were evaluated at a mean 13years of follow-up (range, 2-23years) with Oxford score and hip radiograph analysis including the Stulberg grade, coxometry, and presence of a femoral bump. FAI was characterized by positional hip pain with preserved joint space and aspherical/nonspherical femoral head. RESULTS: The Oxford score was optimal (12) in 79 hips (75%) and 20 or above in nine hips (9.5%). Seventeen hips were rated Stulberg I (18%), 36 Stulberg II (38%), 27 Stulberg III (28%), and 15 Stulberg IV or V (16%). The average acetabular angle was 10° (range, -4 to 25), VCE 41.5° (range, 18-80), and VCA 38.5° (range, 13-70). A femoral bump was noted in 31 hips (33%). Five cases of FAI were managed operatively with at least pain relief. Hip pain at the latest follow-up correlated with coxa plana (P=0.0003) and femoral bump (P=0.007). No significant correlation was found with a history of hip surgery or coxometry parameters. CONCLUSION: Perthes hips bear risk for later FAI. Risk factors include coxa plana and femoral bump. In case of TOP, it is advocated to avoid excessive tilt, which may cause FAI. LEVEL OF EVIDENCE: IV.

BACKGROUND: Outcomes after arthroscopic femoro-acetabular impingement (FAI) surgery are promising in the short-term but have rarely been evaluated in the mid-term (e.g., about 5 years). Here, our objectives were to obtain mid-term data on functional and radiographic outcomes, to identify prognostic factors, and to determine the mid-term rate of arthroplasty revision with the associated risk factors. HYPOTHESIS: We hypothesized that the results of arthroscopic FAI surgery were sustained over time. MATERIALS AND METHODS: We conducted a prospective multi-surgeon study of 53 Tönnis grade 0 or 1 hips treated arthroscopically for symptomatic FAI (23 cam, 10 pincer, and 20 mixed deformities). We obtained short-term (10 months) and mid-term (4.6 years) data on the functional outcome (WOMAC and satisfaction scores), proportion of patients without revision arthroplasty, and development of osteoarthritis (graded using the Tönnis classification). RESULTS: In the patients without revision arthroplasty, the WOMAC score improved significantly (P<0.01) from baseline (61.4 ± 15.6) to 10 months (84.2 ± 15.6) and last follow-up (85.2 ± 15.5) but remained unchanged between the two postoperative time points, confirming the stability of the results. The proportion of satisfied patients was 79% after 10 months and 68% (36/53) at last follow-up (NS). Osteoarthritis developed in 13/35 (37%) hips for which radiographs were obtained at last follow-up. At last follow-up, 46/53 hips (87%; 95%CI, 78-96) did not required revision surgery; arthroplasty was required in the 7 remaining hips. The main prognostic factor was the preoperative osteoarthritis Tönnis grade: at last follow-up, compared to Tönnis grade 0 hips, Tönnis grade 1 hips had lower WOMAC scores (77 vs. 88), lower satisfaction rates (50% versus 77%), a higher rate of osteoarthritis progression (57% versus 24%), and a higher rate of arthroplasty (33.3% versus 2.9%). DISCUSSION: Our results are consistent with published data. The outcomes of arthroscopic FAI surgery are sustained over time and the preoperative osteoarthritis status is the main predictor of mid-term outcomes. LEVEL OF EVIDENCE: IV, prospective cohort study.

UNLABELLED: Harvesting the patellar ligament for anterior cruciate ligament reconstructions can be a source of anterior knee pain and hypoesthesia of the lateral side of the knee. We analyzed the feasibility of a minimally-invasive technique via a single patellar approach and postulate that it reduces anterior pain and limits the hypoesthesia area. PATIENTS AND METHODS: A prospective, comparative, non-randomized, single-center study was conducted on two groups: one undergoing surgery with the classical anteromedial approach, the other with the minimally-invasive approach. Each group included 20 patients. Both series were reviewed between the 6th and 8th month after surgery. The revision was clinical, radiological, and ultrasonographic. RESULTS: The grafts harvested via the classical approach in all 20 cases presented good characteristics, versus eight out of 18 for the grafts harvested via the minimally-invasive approach. A prominent anterior tibial tuberosity improved the quality of the tibial bone block. A hypoesthesia zone was found in 16 cases out of 18 in the classical approach group, it measured a mean 10.3 ± 5.6 cm(2). A surface area of 3 cm(2) was noted in one case from the minimally-invasive group. No significant difference was found for the subjective and objective IKDC and Lille patellofemoral scores between the two groups. Anterior pain was present in four patients in the classical group and six in the minimally-invasive group. DISCUSSION: The minimally-invasive technique reduces the risk of cutaneous hypoesthesia. It does not prevent anterior pain related to harvesting the patellar tendon and a good-quality transplant can be obtained if the anterior tibial tuberosity is prominent. LEVEL OF EVIDENCE: Level III: case-control study.

INTRODUCTION: Surgical treatment of femoroacetabular impingement can be performed under arthroscopic control, to limit associated morbidity. Encouraged by recent good reports, arthroscopy is replacing alternative techniques for this indication. HYPOTHESIS: Arthroscopy enables femoroacetabular impingement to be corrected with a low rate of associated morbidity. AIM OF STUDY: To assess the indications for and quality of the technique and its impact on preliminary results and complications. To investigate preoperative prognostic factors. PATIENT AND METHODS: One hundred and eleven hips in 110 patients (78 male, 32 female; mean age, 31 years) were operated on under arthroscopic control for femoroacetabular impingement, by six senior surgeons. Sixty-five patients showed no radiographic sign of osteoarthritis, and 36 showed grade-1 early osteoarthritis on the Tönnis scale. RESULTS: Mean WOMAC score rose from 60.3 preoperatively to 83 (p<0.001) at a mean 10 months' FU (range, 6-18 mo). Seventy-seven percent of patients were satisfied or very satisfied with their result. Patients with early osteoarthritis had significantly lower WOMAC and satisfaction scores than those free of osteoarthritis. Operative crossover to open surgery occurred in only one case. Five patients (4%) had revision: total hip replacement or resurfacing. There were seven complications (6%): three cases of heterotopic ossification, one of crural palsy, one of pudendal palsy, one of labium majus necrosis, and one non-displacement stress fracture of the femoral head/neck junction (managed by non-weight-bearing). There was no palsy of the territory of the lateral cutaneous nerve of the thigh. DISCUSSION: Results confirmed the efficacy and low associated morbidity of arthroscopy in the management of femoroacetabular impingement. Short-term functional results matched those of the literature. Planning and assessment seem not yet to be fully standardized. Preoperative osteoarthritis on X-ray was associated with poorer functional results. This attitude does not seem to be indicated for hips showing evolved osteoarthritis (>grade 1).

Two hundred and ninety-two patients, aged between 16 and 50 years and presenting with mechanical hip pathology, were included in a prospective multicenter study. The descriptive study concerned the clinical examination and analysis of three X-ray views (AP pelvic, Lequesne false profile and lateral axial view). The series comprised 62% males, mean age 35 years, with 53% right side and 22% bilateral involvement. Initial trauma was reported in 19% of cases, and direct familial history of hip pathology in 20%. Seventy percent of the patients played sports, 30% were high-level athletes, and 17% played combat sports. The physical impingement sign was present in 18% to 65% of cases depending on the variant studied. On imaging (n=241), 62% of hips showed osteoarthritis, with 25% at the evolved stage. In the series, as a whole, there was a 35% rate of dysplasia, 63% of impingement and 5% of normal X-ray results. The radiologic impingement aspects were 58% cam-type, 19% pincer-type and 23% mixed. Twenty-two percent of dysplasia cases showed signs of associated impingement. Pain experienced exclusively in flexion/internal rotation/adduction on examination showed little sensitivity (20%) but considerable specificity (86%) for the main diagnosis of impingement. The links between impingement and dysplasia are discussed, and an integrative schema of all risk factors is put forward.

A retrospective review of 29 patients (30 knees) was carried out who had previously undergone a single-stage combined ACL reconstruction with valgus upper tibial osteotomy for chronic ACL rupture coupled with early medial tibio-femoral arthritis. Of the 30 knees, 19 (63%) had had a previous medial meniscectomy. Major complications occurred in two knees resulting in stiffness. At a mean of 12 years follow-up (6-16 years) only five knees (17%) had progressed one arthritis grade. Fourteen patients (47%) returned to intensive sports, and a further 11 (37%) played moderate sports. The mean difference in anterior tibial translation with the opposite normal knee was 3 mm at review. It was concluded that the combined operation has a low morbidity, controls anterior laxity, allows many patients to return to sports, and does not result in a rapid progression of osteoarthritis.

The present review analyzes the rare indications for sagittal knee osteotomies either for some complex cases of capsular and ligamentous laxities in combination with or without bony deformities in the sagittal plane. A thorough clinical and radiological analysis of the patients' knees is mandatory. We routinely recommend lateral standing X-rays to assess not only the bony structures, but also an abnormal knee laxity in the sagittal plane. We present different surgical options and preliminary results of these technically demanding procedures.

INTRODUCTION: The aim of this study was to evaluate subjective and functional results of a prospective continuous series of immediate tendon-to-bone repair of the F.D.L. using a miniaturized anchor. METHOD: Seven patients have been operated by the same surgeon in emergency for a section of the FDL in zone one. Distal tendon-to-bone re-attachment has been realized using a mini-G II Mitek anchor suture. Five of the patient were male, four of them being manual workers. Only one had a work accident. According to Leddy and Packer's classification one patient had a stage 1 lesion and the six others had stage two lesions. The injured fingers showed associated lesions in four cases. Rehabilitation consisted of early active mobilization protected by a Duran-type splint. All the patients had been examined by an independent surgeon at 10 months follow-up. Mean age at that time was 32 years. RESULTS: One patient was very satisfied with his results while the six others were satisfied. Two minor complications were encountered, one of them being directly in relation to the implant. Total Active Motion (TAM) summed up to 92% of the arch of motion of the normal controlateral finger. Pinch-force reached 81% compared to that of the controlateral finger. Two patients described no pain. Mean eviction from work was 70 days. DISCUSSION: Tendon-to-bone repair of the FDL using an anchor seems to give good results on pain, TAM and on force. The only complication due to the implant did not have any functional incidence. The series of Marin Braun on 77 cases of such repairs using a barb-wire show similar results compared to the implant used in our series. However, anchor sutures have several advantages compared to a transcutaneous device: they reduce the risk of infection, of nail dystrophy and they offer a better comfort to the patient.

The effects of somatostatin on diarrhea and on small intestinal flow of water and electrolytes (slow-marker perfusion technique) in a patient with pancreatic cholera are reported. Continuous intravenous infusion of somatostatin (8 micrograms/kg/hr) suppressed the diarrhea, but a rebound was observed after somatostatin. Infusion of somatostatin at the same dosage decreased the ileal fluid flow rate to within control values. This effect was mainly due to a sharp reduction in the rate fluid entered the jejunum, but was also due to a suppression of the abnormal water and electrolyte secretion in the proximal jejunum. Secretion in the rest of the small bowel remained unchanged. Somatostatin did not noticeably alter the high preinfusion plasma level of prostaglandin E1, but decreased the initially high plasma concentration of vasoactive intestinal peptide to normal values. These results suggest that long-acting somatostatin analogs could be of value in the symptomatic treatment of diarrhea in pancreatic cholera.
