Can the number of surgery delays and postponements due to unavailable instrumentation be reduced? Evaluating the benefits of enhanced collaboration between the sterilization and orthopedic surgery units. Orthop Traumatol Surg Res 2019; 105:563-568. [PMID: 30862491 DOI: 10.1016/j.otsr.2019.01.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 01/10/2019] [Accepted: 01/25/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The development of outpatient surgery, cost-reduction pressures and instrumentation storage limitations have led to their use "just-in-time". A recent study showed that stoppage of surgical procedures immediately before the incision (No-Go) was often due to the management of supplies and implantable medical devices. To our knowledge, since the development of outpatient surgery and the shortening of hospital stays, managing the flow of instrumentation has not been optimized. At our hospital, we used a two-prong approach consisting of a tool to manage instrumentation and working group from the sterilization and orthopedic surgery units. The aims of this study were to: 1) evaluate whether this approach led to better notification of the risk of supply shortage for instrumentation and 2) determine whether it could reduce by at least half operating room disruptions such as delays or cancellation of surgical procedures. HYPOTHESIS This approach results in better notification of the risk of supply shortage for instrumentation and reduces by at least half operating room disruptions such as delays or cancellation of surgical procedures. MATERIAL AND METHODS A tool was developed to manage instrumentation flow based on a retrospective analysis of data from 2015. This tool consisted of: (1) a list of instrumentation needed for each surgical procedure from an analysis of the surgical schedule and verification of traceability labels of the instrumentation actually used, (2) a list of reasons for supply shortage identified from an analysis of non-conformities occurring in the sterilization process of instrumentation kits. These analyses resulted in the development of checklists for instrument sets for each procedure, while identifying those with a high risk of shortage. In 2017, a working group focused on instrumentation was set up with personnel from the sterilization unit and the orthopedic surgery unit. Based on the check-lists and the schedule 24hours before the surgery, the sterilization unit alerted the surgery unit by email of the risk of material shortage; the surgery ward replied with potential changes to the material or the surgery planning. This approach (instrumentation management tool and working group) was named just-in-time (JIT). The main outcome was the number of notifications of potential supply shortage with and without JIT over a 10-week period. The secondary outcomes were the number of notifications resolved in time and the occurrence of operating room disruptions (delay>30min or postponement of surgery) related to unavailable instrumentation. RESULTS Nine reasons for potential supply shortage were identified such as instrumentation kits used for several types of procedures, those with fast rotation and low stock, or in double pathways (on loan and on deposit). The working group reported 163 potential shortages with JIT versus 41 without (p<10-5), of which 150 (92.5%) were resolved. Thirteen operating room disruptions occurred; only one was not detected by the JIT approach. CONCLUSION Our JIT approach (instrumentation management tool and working group) is effective at preventing instrumentation supply shortages. LEVEL OF EVIDENCE III, prospective comparative study.

Treatment of infected non-unions of the femur and tibia in a French referral center for complex bone and joint infections: Outcomes of 55 patients after 2 to 11 years. Orthop Traumatol Surg Res 2018; 104:137-145. [PMID: 29246480 DOI: 10.1016/j.otsr.2017.10.014] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2016] [Revised: 08/25/2017] [Accepted: 10/30/2017] [Indexed: 02/02/2023]
Abstract
INTRODUCTION An infected non-union is a major complication following bone fracture. While bone union can be obtained in 70% to 100% of cases, treatment of osteomyelitis is less predictable, with reported healing rates ranging from 40% to 100%. The primary aim of this study was to assess the success rate of treating infected non-unions of the tibia and femur by a team specializing in complex bone and joint infections. MATERIAL AND METHODS This single-center retrospective study included all patients operated between 2002 and 2012 due to an infected non-union of the femur or tibia using standardized surgical methods. The procedure was typically done in two phases: excision of the infected site and stabilization, followed by bone reconstruction after a waiting period. Additional procedures (lavage and/or bone grafting) were performed in some cases. A minimum 6-week course of antibiotic therapy was given. The primary endpoint was successful medical and surgical treatment after a minimum 2 years' follow-up defined as healing of the infection (no local clinical signs of infection, ESR≤20mm and CRP≤10mg/L, no mortality attributed to the infection) and radiological and clinical bone union, with the lower limb spared. RESULTS Fifty-five patients (39 men, 16 women) were included with an average age of 37±11 years. There were 40 tibial fractures and 15 femur fractures. A polymicrobial infection was present in 47% of cases. Repeat surgery was required in 56.4% of patients. At an average of 4±2 years from the first surgical procedure, the treatment was successful in 49 patients (89%): 36 tibia (90%) and 13 femur (87%). The mean time to union was 9±4 months. There were six failures: 3 amputations at 5, 6 and 16 months; 1 mechanical and infection-related failure; 2 failed union. CONCLUSION This study found that 89% of patients with an infected tibial or femoral non-union treated by a team specialized in complex bone and joint infections using a standardized surgical protocol had bone union and healing of the infection in an average of 9 months.

Efficacy of vitamin C in preventing complex regional pain syndrome after wrist fracture: A systematic review and meta-analysis. Orthop Traumatol Surg Res 2017; 103:465-470. [PMID: 28274883 DOI: 10.1016/j.otsr.2016.12.021] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2016] [Revised: 12/05/2016] [Accepted: 12/14/2016] [Indexed: 02/02/2023]
Abstract
BACKGROUND Complex regional pain syndrome type I (CRPS-I), previously known as reflex sympathetic dystrophy, is common after conservatively or surgically treated wrist fractures. Several studies support the efficacy of vitamin C in preventing CRPS-I, although the data are somewhat conflicting. The primary objective of this systematic literature review and meta-analysis was to assess the efficacy of vitamin C therapy in preventing CRPS-I after a wrist fracture. METHODS Randomised, placebo-controlled trials of vitamin C to prevent CRPS-I after wrist fractures were sought in the three main databases: PubMed (1980 to December 2015), CENTRAL (Central 2015, number 12), and Embase (1980 to December 2015). Two authors worked independently to select articles. Data from selected articles were collected independently. RESULTS Three randomised placebo-controlled trials in a total of 875 patients were included. Treatment was non-operative in 758/890 (85.1%) fractures and operative in 132 (14.9%) fractures. Vitamin C supplementation was started on the day of the injury and continued for 50 days. In the group given 500mg of vitamin C daily, the risk ratio for CRPS-I was 0.54 (95%CI, 0.33-0.91; P=0.02). Thus, the risk of developing CRPS-I was significantly decreased by prophylactic treatment with 500mg of vitamin C per day. The heterogeneity rate was 65% (non-significant). CONCLUSION Daily supplementation with 500mg of vitamin C per day for 50 days decreases the 1-year risk of CRPS-I after wrist fracture.

Peri-articular local infiltration analgesia versus femoral nerve block for postoperative pain control following anterior cruciate ligament reconstruction: Prospective, comparative, non-inferiority study. Orthop Traumatol Surg Res 2016; 102:873-877. [PMID: 27720193 DOI: 10.1016/j.otsr.2016.07.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2016] [Revised: 06/20/2016] [Accepted: 07/05/2016] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain. PATIENTS AND METHODS A retrospective analysis of data collected prospectively in the FAST cohort included a series of continuous patients who underwent primary repair for isolated ACL with a hamstring graft in 2013-2014. Changes in our anesthesia practices over time allowed us to form three successive groups: Group 1 - FNB, Group 2 - FNB+LIA, Group 3 - LIA only. Ultrasound-guided FNB was done pre-operatively. The LIA was done at the end of the procedure by the surgeon with systematic infiltration of all skin incisions and the hamstring donor site; no intra-articular injections were performed. The primary endpoint was the average early postoperative pain (Days 0-3) described by the patient on a visual analogue scale (0-10). Sample size calculation pointed to 36 subjects being needed per group for a non-inferiority study. RESULTS The study involved 126 patients: G1=42, G2=38, G3=46. The patients were comparable at enrolment. The average early postoperative pain levels were 3.1±2.4, 2.8±2.0 and 2.5±2.2, respectively (P=0.66). A trend toward higher intake of tramadol was noted in the LIA group on D0 to D3, with a significant trend test on Day 1 (P=0.03) and Day 2 (P=0.02). CONCLUSION After reconstruction of isolated ACL tears with a hamstring graft, FNB is not more effective than LIA on patients' early postoperative pain. Patients who received a FNB consumed significantly less opioid-like analgesics. LEVEL OF EVIDENCE III - Prospective, comparative, non-randomized study.

Outpatient Latarjet surgery for gleno-humeral instability: Prospective comparative assessment of feasibility and safety. Orthop Traumatol Surg Res 2016; 102:507-12. [PMID: 26944815 DOI: 10.1016/j.otsr.2015.12.019] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2015] [Revised: 10/21/2015] [Accepted: 12/23/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND Some surgical procedures are rarely done on an outpatient basis. The primary objective of this study was to assess the safety of outpatient surgical shoulder stabilisation using the Latarjet procedure. HYPOTHESIS The Latarjet procedure is safe when performed on an outpatient basis provided the patients are managed according to a specifically designed programme starting at the decision to undergo surgery and ending at the end of the early postoperative period. PATIENTS AND METHODS Consecutive patients with unidirectional anterior shoulder instability managed in 2013-2014 by primary open, minimally invasive surgery involving coracoid process transfer as described by Latarjet was included prospectively. One of the surgeons routinely offered outpatient surgery to patients who met none of the usual exclusion criteria (age>60years, ASA 3-4, and long distance from home to hospital). Standardised protocols were applied for anaesthesia and analgesia. The primary evaluation criterion was failure of the admission modality, defined as inpatient admission of a patient after outpatient surgery either without prior discharge or within 1week after discharge. Secondary evaluation criteria were early postoperative symptoms and functional outcomes after at least 1year. All self-reported criteria were entered online by the patients. RESULTS Of 46 included patients, 17 had outpatient surgery and 29 inpatient surgery. There were 41 males and 5 females, with a mean age of 25.3±6.4years. No significant baseline differences were found between the two groups. None of the outpatients required inpatient admission or readmission. No postoperative complications were recorded. After a mean follow-up of 18.5±5.2months, the two groups showed no significant differences for return to sports, apprehension, avoidance behaviours, or functional outcomes. Most patients were satisfied with their management and outcomes. CONCLUSION No serious adverse events were recorded in this first French prospective evaluation of the safety of open, minimally invasive shoulder stabilisation by the Latarjet procedure performed on an outpatient basis. Thus, in selected patients, the risks of outpatient surgery are similar to those of inpatient surgery. LEVEL OF EVIDENCE III, prospective, comparative, non-randomised study.

Abstract
INTRODUCTION Kinesio-Taping(®) (K-Tape) is used in sports traumatology with the aim of reducing pain and improving blood and lymph circulation. The main objective of the present study was to assess the efficacy of K-Tape on early postoperative pain after anterior cruciate ligament (ACL) reconstruction. The study hypothesis was that K-Tape significantly decreases pain. METHOD A prospective non-randomized comparative study was conducted in 2013-2014 and included all patients who underwent primary ACL reconstruction by hamstring graft. Analgesia was standardized. Two groups, "K-Tape" and "controls", were formed according to the days on which the study physiotherapist was present. The K-Tape compression/decompression assembly was applied immediately postoperatively and maintained for 3days. Patients filled out online questionnaires. The main assessment criterion was mean postoperative pain (D0-D3) on a 0-to-10 scale. Secondary criteria were analgesia intake on the three WHO levels, awakening during the night of D0 due to pain, signs of postoperative discomfort, and patient satisfaction. RESULTS Sixty patients (30 per group) were included, 57 of whom could be assessed: 28 K-Tape, 29 controls; 44 male, 13 female; mean age, 30.9±8.9 years. At inclusion, the two groups were comparable. There was no significant difference in mean (D0-D3) knee pain intensity: 3.8±2.2 for K-Tape, and 3.9±2 for controls (P=0.93). Analysis of variance (ANOVA) found no significant intergroup difference in evolution of pain (P=0.34). There were no other significant differences on the other assessment criteria. CONCLUSION K-Tape showed no efficacy on early postoperative pain following ACL reconstruction. LEVEL OF EVIDENCE III; prospective non-randomized comparative study.

Abstract
INTRODUCTION Fixed-bearing total knee arthroplasty (TKA) implants have excellent long-term survival. Mobile-bearing implants were developed to reduce bone-implant interface stresses and polyethylene insert wear. The primary objective of this study was to analyze the survival rate of a highly congruent mobile-bearing TKA implant (Ceragyr(®)) in patients having a minimum follow-up of 7 years. We hypothesized that the survival rate would be 95-100% at that time point. PATIENTS AND METHODS A single-center prospective study included all the patients operated for a primary TKA procedure with a Ceragyr(®) implant between 2000 and 2003. All the implants were cemented. Patellar resurfacing was not carried out systematically, but could be carried out secondarily in cases of persistent anterior knee pain. Clinical and radiological data were collected before the surgery, at 3 months postoperative, at 1 year and then at a minimum follow-up of 7 years. The primary endpoint was the overall revision-free survival rate. Secondary endpoints were the survival without mechanical failure, IKS scores, knee range of motion and implant positioning. RESULTS One hundred and thirty-four patients (143 Ceragyr(®) TKA cases) were included; 9 patients (10 TKA) were lost to follow-up (6.7%) and the remaining 125 patients (133 TKA) were contacted. At the final review, 7 of the 133 TKA cases (5.3%) had been revised (6 men, 1 women; P = 0.002), 2 (1.5%) because of mechanical failure and 5 (3.8%) because of an infection. The overall revision-free survival rate was 94.8% [95% CI: 89.3-97.5]; survival was 98.4% [95% CI: 93.8-99.6] with mechanical failure as an endpoint. An in-person assessment was conducted on 76 patients (80 TKA cases) (49 women; 27 men) who had an average age of 70.3 ± 8.4 years at the time of the arthroplasty procedure. The patella had been resurfaced during the initial procedure in 49 cases, and was either not resurfaced or secondarily resurfaced in 31 cases. The average follow-up was 8.7 ± 1.1 years. The IKS score had significantly improved relative to the preoperative values (P < 0.00001). Knee flexion and the IKS knee score remained stable over time (P > 0.05). Patients who underwent patella resurfacing during the initial TKA procedure had better clinical results (P = 0.03). CONCLUSION After a minimum follow-up of 7years, the overall revision-free survival rate for the Ceragyr(®) was 94.8%; the survival was 98.4% with mechanical failure as an endpoint. The results were stable over time.

Translation, cross-cultural adaptation and validation of the French version of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale. Knee Surg Sports Traumatol Arthrosc 2015; 23:1192-6. [PMID: 24676789 DOI: 10.1007/s00167-014-2942-4] [Citation(s) in RCA: 72] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2013] [Accepted: 03/09/2014] [Indexed: 10/25/2022]
Abstract
PURPOSE The aim of this study was to translate, adapt and validate in French the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI), a 12-item English language scale assessing the psychological impact of returning to sports after ACL reconstruction. METHODS The ACL-RSI scale was forward and back translated, cross-culturally adapted and validated using international guidelines. The study population included all patients who were active in sports and underwent primary arthroscopic ACL reconstruction. The control group included subjects with no history of knee trauma. At the 6-month follow-up, the study population completed the ACL-RSI scale twice within 3-4 days, Knee injury and Osteoarthritis Outcome Score (KOOS) and subjective International Knee Documentation Committee (IKDC) scores. Statistical tests assessed the construct validity, discriminant validity, internal consistency, reliability and feasibility of the ACL-RSI scale. RESULTS Ninety-one patients with ACL tears and 98 control subjects were included: mean age 31.7 ± 8.1 and 21.8 ± 2, respectively. The ACL-RSI scores were correlated with all KOOS sub-categories (r = 0.22-0.64, p < 0.05) as well as the subjective IKDC score (r = 0.42, p < 0.00001). The mean scores of the study and control groups were significantly different (62.8 ± 19.4 vs. 89.6 ± 11.5, p < 0.00001), and scores were significantly better in patients who returned to the same sport (72.1 ± 21.4 vs. 60.3 ± 18.1, p = 0.008). Internal consistency was high (α = 0.96). Test-retest reproducibility was excellent: ρ = 0.90 (0.86-0.94), p < 0.00001. Administration time was 1.32 ± 0.7 mn, and all items were answered. CONCLUSION This study showed that the cross-cultural adaptation of the English version of the ACL-RSI was successful and validated in a French-speaking population. The discriminant capacity of the scale between patients who underwent reconstruction and healthy subjects was confirmed. LEVEL OF EVIDENCE II.

Abstract
INTRODUCTION The principal objective of the present study was to compare rates of postoperative discomfort after anterior cruciate ligament (ACL) reconstruction between inpatient (In) and outpatient (Out) management. PATIENTS AND METHOD A single-surgeon non-randomized prospective comparative study included patients undergoing primary surgery for isolated ACL tear by short hamstring graft in 2012-13. The Out group comprised patients eligible for and consenting to outpatient surgery and the In group, those not eligible or not consenting. The principal assessment criterion was onset of at least 1 symptom of postoperative discomfort (SPD): anxiety, nausea and vomiting, malaise, vertigo or stomach pain, between postoperative days 0 and 3. Secondary assessment criteria were difficulty in getting to sleep, getting up during the night, regular walking or going out, number of episodes of knee pain and waking because of pain. All criteria were assessed on-line by the patient. RESULTS One hundred and thirty-three patients filled out the questionnaire, 70 in the Out group and 63 in the In group; 42 females, 91 males; mean age, 30±9 years. Between D0 and D3, the proportion of patients with ≥l SPD was comparable between groups (Out 37% vs In 41%, P=0.62). Out-group patients had significantly less difficulty sleeping the first postoperative night (P=0.01), got up significantly more often during the first night after surgery (P<0.0001), more often walked regularly on day 1 (P=0.03), and were significantly less often woken by pain during the first night (P=0.003). Risk factors for SPD were female gender (OR=4.8±1.9) and postoperative complications (OR=3.8±2.5). CONCLUSION Patients undergoing ACL reconstruction on an outpatient basis did not show more symptoms of postoperative discomfort than those managed as conventional inpatients.

Abstract
BACKGROUND Difficulties in knee exposure during revision total knee arthroplasty (RTKA) may require tibial tubercle osteotomy (TTO). The main objective of this study was to assess union after TTO hinged on the lateral soft tissues and fixed using circumferential cable cerclage during RTKA. HYPOTHESIS Non-union is uncommon with this technique. PATIENTS AND METHODS We retrospectively included consecutive patients who underwent RTKA between 2008 and 2010 with TTO. Chevron osteotomy was performed and the fragment was left hinged laterally on the tibialis anterior muscle then fixed using circumferential cerclage with one or two steel cables. The primary evaluation criterion was TTO union as assessed on radiographs. Secondary evaluation criteria were time to union, osteotomy fragment migration, patellar height, and the IKS score at last follow-up. We included 65 patients with a mean age of 72±11.3 years including 39 (60%) undergoing septic revision and 26 (40%) aseptic revision. Mean follow-up was 27.8±10.7 months; there was 1 early death, which was unrelated to the surgery, and another patient was lost to follow-up. RESULTS TTO union was achieved in 59/63 (93.7%) patients. Fragment migration occurred in 4 (6.3%) patients. Mean time to union was 16.9±5.1 weeks overall, 12.4±2.0 in the aseptic revision group, and 18.9±4.8 in the septic revision group (P=0.0005). Patellar height at last follow-up was not significantly changed compared to the preoperative value (P=0.09). At last follow-up, the mean IKS knee and function scores were significantly improved (P<10-5). CONCLUSION TTO hinged on the lateral soft tissues and fixed by circumferential cable cerclage ensured union in the vast majority of patients, with a low rate of tubercle migration.

Abstract
INTRODUCTION The main objective of this study was to assess the feasibility of outpatient surgery in anterior cruciate ligament (ACL) reconstruction. We hypothesized that if the patient underwent the procedure within a dedicated organization, safety would be ensured. PATIENTS AND METHODS A non-randomized, prospective, comparative, single-operator study conducted in 2012-2013 included all patients undergoing first-line surgery for ACL arthroscopic reconstruction using a short hamstring graft. The outpatient group (OP) included patients who were eligible for outpatient surgery and provided consent; the conventional hospitalization group (CH) comprised those patients not suitable for outpatient surgery and those who refused it. The main evaluation criterion was failure of the admission modality defined as hospitalization of a patient who had undergone outpatient surgery or rehospitalization in the first week after discharge. The secondary evaluation criteria were the rate of postoperative complications, postoperative pain, use of analgesics, and patient satisfaction. A total of 138 patients were included: 71 in the OP group and 67 in the CH group, with a mean age of 29.6±9 years. Twenty-nine percent of the patients refused outpatient surgery. In the CH group, the mean hospital stay lasted 2.7±0.8 days. RESULTS One patient in the OP group was hospitalized with localized bleeding and there were no rehospitalizations. Six early postoperative complications were noted in each group. The mean postoperative pain on D0-D4 and patient satisfaction were similar in the two groups. CONCLUSION This prospective study encountered no serious events after outpatient ACL reconstruction surgery. In a selected population, the risks are comparable to those in conventional hospitalization. LEVEL OF EVIDENCE Level III, comparative study.

Ceramic-on-ceramic total hip arthroplasty: is squeaking related to an inaccurate three-dimensional hip anatomy reconstruction? Orthop Traumatol Surg Res 2014; 100:437-40. [PMID: 24736014 DOI: 10.1016/j.otsr.2014.01.009] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2013] [Revised: 01/14/2014] [Accepted: 01/31/2014] [Indexed: 02/02/2023]
Abstract
Many factors were incriminated in the squeaking generation in ceramic-on-ceramic total hip arthroplasty (THA), including the cup positioning and design. However, the influence of the stem orientation has not been investigated and the true three-dimensional hip anatomy has never been compared to the contralateral healthy hip. Three patients, who underwent unilateral ceramic-on-ceramic THA, complained of squeaking. CT-scans were performed to compare the true three-dimensional hip anatomy to the contralateral healthy hip. All patients presented evidence of posterior neck-rim impingement with a two-fold increase in the global anteversion (above 75°) comparatively to the healthy hip. The excess of anteversion was on the cup side in 2 cases and on the stem side in 1 case. We conclude that squeaking in ceramic-on-ceramic THA could be related to a poor accuracy of 3D hip anatomy reconstruction which generated a posterior impingement and subsequent anterior edge loading because of excessive global anteversion.

Sensitivity and specificity of bell-hammer tear as an indirect sign of partial anterior cruciate ligament rupture on magnetic resonance imaging. Knee Surg Sports Traumatol Arthrosc 2014; 22:1112-8. [PMID: 23604176 DOI: 10.1007/s00167-013-2511-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2012] [Accepted: 04/15/2013] [Indexed: 11/24/2022]
Abstract
PURPOSE The main purpose of this study was to evaluate the usefulness of the bell-hammer sign in the diagnosis of partial tears of the anterior cruciate ligament (ACL) of the knee on MRI. METHODS A retrospective study was performed including all patients who underwent ACL reconstruction for partial or complete tears from 2008 to 2009. The diagnosis of partial or complete ACL tears was based on the appearance of the ligament bundles and the signal quality on MRI. On arthroscopy, which is considered the gold standard, each bundle was classified as normal, partially or completely torn depending on the extent of the rupture and the quality of the remaining fibres. The study included 312 patients, 83 women and 229 men (mean age 33.3 ± 19.6 years). A diagnosis of a tear was made in all patients on preoperative MRI. Arthroscopy did not show any normal ACL, 247/312 (79.2 %) complete tears and 65/312 (20.8%) partial tears, 50/65 (76.9%) on the anteromedial bundle (AM) and 15/65 (23.1%) the posterolateral bundle. RESULTS The bell-hammer sign was found on MRI in 13/312 patients (4.5%). It involved 9/65 (13.8%) partial tears, all in the AM bundle, and 4/247 (1.6%) complete tears, significantly more frequent in cases of partial rupture (p < 0.0001). MRI diagnosed a partial tear in 15/65 cases without the bell-hammer sign (sensitivity CI 95% = 23.1 ± 10%, specificity CI 95% = 95.9 ± 2.5%) and with the bell-hammer sign in 23/65 cases (sensitivity CI 95% = 35.4 ± 11%, specificity CI 95% = 93.9 ± 3%). The association of the bell-hammer sign with conventional radiological diagnostic criteria has improved diagnosis performance of MRI for partial tears but not significantly (ns). CONCLUSION The most important interest of the bell-hammer sign in the day-to-day clinical work is to suggest partial tears on MRI. It aids making a diagnosis, but its absence does not exclude partial ACL rupture. LEVEL OF EVIDENCE Diagnostic study, Level II.

Abstract
INTRODUCTION Whether rotator cuff repair is indicated in an elderly subject depends on the patient's activity profile and functional demand. A Senior Shoulder Activity (SSA) score is described, as a support for indications and analysis of clinical results according to activity level. MATERIAL AND METHOD The SSA score, comprising 4 levels from "sedentary" to "very active", was validated by comparison against a control group of 113 asymptomatic patients. It was included in the protocol of the French Arthroscopy Society's comparative study of repair versus simple decompression in 143 rotator cuff tears. Recovery of activity was assessed according to procedure. RESULTS At 1-year follow-up, suturing was associated with recovery of previous activity level in 87% of the cases and in 80% for decompression, a non-significant difference. When, however, less active patients (SSA 1 and 2) were contrasted with the more active (SSA 3 and 4), clinical results with suture versus decompression on Constant score showed a greater difference in the SSA 3-4 group. DISCUSSION The SSA score is not the same as the activity item of the Constant score, as it assesses the patient's usual activity level, before symptom onset, whereas the Constant item assesses activity at a given moment, independently of the patient's normal activity profile. CONCLUSION The Senior Shoulder Activity score is a simple, reproducible complement to the Constant score, revealing differences in clinical results on the latter, according to activity profile. Rotator cuff repair or simple decompression provided recovery of previous SSA activity level in more than 80% of the cases. The difference in clinical results between the two was significantly greater in more active patients. It would seem to follow that suture is more beneficial for more active subjects while simple decompression may be suitable for those with lower functional demand.

Primary arthroscopic synovectomy for pigmented villo-nodular synovitis of the knee: recurrence rate and functional outcomes after a mean follow-up of seven years. Orthop Traumatol Surg Res 2013; 99:937-43. [PMID: 24161841 DOI: 10.1016/j.otsr.2013.08.004] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2013] [Revised: 07/22/2013] [Accepted: 08/21/2013] [Indexed: 02/02/2023]
Abstract
BACKGROUND Pigmented villo-nodular synovitis (PVNS) is an uncommon proliferative condition of the synovial membrane that chiefly affects the knee. Arthroscopic synovectomy may carry lower morbidity rates but higher recurrence rates than open synovectomy. Here, our objective was to evaluate recurrence rates and functional outcomes after primary arthroscopic synovectomy for PVNS of the knee. HYPOTHESIS Primary arthroscopic synovectomy preserves knee function while producing low recurrence and complication rates. MATERIALS AND METHODS We retrospectively included consecutive patients with histologically documented PVNS managed with primary arthroscopic synovectomy at two centres between 1998 and 2011. Twenty-three patients, 13 men and 10 women with a mean age of 41 ± 12 years, were reviewed including 16 patients with nodular and 7 with diffuse form of this disease. Patients with localized disease underwent partial synovectomy and those with diffuse disease complete synovectomy followed by chemical synovectomy of any residual lesions. The primary outcome measure was recurrence. Secondary outcome measures were the Tegner-Lysholm and Ogilvie-Harris scores. RESULTS Follow-up data were obtained after a mean of 7 ± 4 years in 21 patients (14 with nodular and 7 with diffuse disease), of whom 2 had recurrences, after 2 and 5 years, respectively. At last follow-up, neither patient had any evidence of recurrence. The mean Tegner-Lysholm score was significantly improved (from 68 ± 10 to 90 ± 8, P=0.0004) and the mean Ogilvie-Harris score indicated excellent function (11 ± 1). DISCUSSION Primary arthroscopic synovectomy ensures satisfactory control of PVNS while preserving knee function. A full recovery remains possible even in patients with diffuse disease. In the event of a recurrence, open synovectomy can be performed.

Abstract
INTRODUCTION Women run a 4-8-fold greater risk of anterior cruciate ligament (ACL) tear than men, and especially during the pre-ovulation stage of their cycle. The main study objective was to describe the distribution of ACL lesions according to menstrual cycle in a large population of female recreational skiers. MATERIALS AND METHODS A prospective study was conducted during the 2010-11 ski season on women sustaining ACL tear during skiing. Patients filled out a questionnaire during consultation with the mountain physician, including date of last menstrual period (LMP) and contraceptive method. Fifty-seven of the 229 patients with diagnosed ACL tear were excluded from analysis, 41 being post-menopausal (mean age, 47 ± 9 years), and 16 having irregular cycles or LMP>30 days. One hundred and seventy-two patients (mean age, 34 ± 8.7 years) were thus included. RESULTS Fifty-eight women (33.72%) were in follicular phase, 63 (36.63%) in ovulatory phase and 51 (29.65%) in luteal phase; difference with respect to the theoretic distribution regardless of menstrual phase was highly significant: χ(2)=48.32; P=0.00001. Fifty-three of the 172 women (30.8%) were taking oral contraceptives. ACL tear was 2.4-fold more frequent in pre-ovulatory than post-ovulatory phase, whether in women using oral or other contraceptives: 85/119 (71.4%) vs. 36/53 (67.9%); P=0.64. CONCLUSION ACL tear risk in skiing in women is not constant over the menstrual cycle, being 2.4-fold more frequent in pre-ovulatory (follicular and ovulatory) than post-ovulatory phase (luteal). Oral contraception seems not to exert any protective effect. LEVEL OF EVIDENCE Level IV. Retrospective cohort study.

Abstract
INTRODUCTION In France, approximately 36,000 anterior cruciate ligament (ACL) reconstruction surgical procedures are performed every year. Technical progress, in particular arthroscopy, has made surgery more precise, but more expensive. In a context of healthcare cost containment, the increase in the cost of technology must be compared to the improved outcome for the patients. The main aim of this study was to determine all material costs related to ACL reconstruction using hamstring tendons. This study also compared the material costs between the two arthroscopic techniques: standard or "all-inside". MATERIALS AND METHODS A retrospective study of material costs was performed in 2011. With the standard technique, the tibial tunnel was drilled from outside to inside, while with the all-inside technique two tunnels were drilled from inside to outside. All of the material used from the first swab to the final bandage was reported. It was classified into three categories: reusable arthroscopy material, disposable arthroscopic material, and disposable surgical supplies. The costs were those of our supplier in 2011 (Arthrex™) and based on Public Hospitals of Paris (AP-HP) public contract tariffs. RESULTS Standard ligament reconstruction was less expensive than the all-inside technique: 791.59€ versus 931.06€ excluding taxes (hors taxes [HT]), respectively. The largest percentage of expenses was allocated to disposable material use (81 and 84%). DISCUSSION Possible avenues of savings are limited: all the material used was necessary. To control costs, correct use and good maintenance of instruments are the most important elements. LEVEL OF EVIDENCE Level IV. Economic and decision analyses, retrospective study.

Surgical technique for repair of acute proximal hamstring tears. Orthop Traumatol Surg Res 2013; 99:235-40. [PMID: 22926295 DOI: 10.1016/j.otsr.2012.05.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2012] [Revised: 05/11/2012] [Accepted: 05/14/2012] [Indexed: 02/02/2023]
Abstract
The surgical technique for repair of acute proximal hamstring tears is relatively recent. Installation of the patient is critical. The approach is either vertical under the gluteal fold in case of a complete tear with tendon retraction of more than 6 cm, or horizontal in the gluteal fold for retraction of less than 6 cm or for partial tears. After identification and neurolysis of the sciatic nerve, transosseous tendon reinsertion is performed with three or four metal or resorbable suture anchors. A rigid brace keeping the leg at 30° of flexion is worn for few days, then replaced by an articulated knee brace for 45 days, which limits extension but allows full flexion. Rehabilitation is begun early. Thirty-four patients underwent surgery for acute proximal hamstring tear and received this treatment. All of the athletic patients were able to return to their pre-injury activities after a mean 5.7 ± 1.6 months (2.3-9.3 months).

Abstract
PURPOSE Although the treatment of choice for acute proximal hamstring ruptures is now surgical repair, this technique is relatively new and requires further evaluation. Our hypothesis was that patients return to sports at the same level after surgical repair as before injury. METHODS From 2002 to 2011, a prospective observational study including 34 patients, mean age 39.3 ± 11.4 years old underwent surgical repair of an acute proximal hamstring rupture. Surgical, rehabilitation and follow-up protocols were standardized. Mean follow-up was 27.2 ± 22.9 months and there were no lost to follow-up. The primary outcome was the level of activity on the UCLA and Tegner scores. RESULTS The mean UCLA score was 9.1 ± 1.3 before injury and 8.7 ± 1.7 at the final follow-up (p = 0.03). The median Tegner activity level was 6 (range, 4-10) before injury and 6 (range, 3-10) at the final follow-up (p = 0.05). The two scores were correlated (r = 0.76, p = 0.00001). Patients returned to sports within a mean 5.7 ± 1.6 months, at the same level in 27 patients (79.4 %) and at a lower level in 7 patients (20.6 %). The average hamstring/quadriceps ratio at 240°/second was 54.7 ± 8.6 % which was positively correlated to the level of activity on the UCLA score (r = 0.49, n.s.). The level of satisfaction was related to their level of activity at the final follow-up (p = 0.03). CONCLUSION Although surgical repair of acute proximal hamstring ruptures has significantly improved the functional prognosis of patients it remains a serious condition that can compromise future sports activities.

Abstract
PURPOSE To compare the performance of 3D-FSE-Cube MRI to arthroscopy, the reference test for the diagnosis of partial anterior cruciate ligament (ACL) tears. METHODS A retrospective study was performed including all patients who underwent surgery for an ACL tear in our Sports Surgery Unit from January 2008 to December 2009. All patients underwent a preoperative MRI, conventional 2D or 3D-Cube. The diagnosis of a partial tear was based on the appearance of the ligament bundles and signal quality on MRI, and on the continuity of the fibers on arthroscopy and the quality of the remaining ligament. Sixty-four of the 312 included patients underwent MRI 3D-Cube and 248 conventional 2D-MRI. The series included 82 women and 223 men, mean age 33.3 ± 19.6 years. Arthroscopy did not reveal any normal ACL, 247/312 (79.2 %) complete tears, and 65/312 (20.8 %) partial tears, with 50/65 (76.9 %) involving the anteromedial bundle and 15/65 (23.1 %) the posterolateral. RESULTS The results of MRI 3D-Cube were as follows: sensitivity 95 % CI = 62.5 ± 23.7 %, specificity 95 % CI = 93.7 ± 6.9 %, likelihood ratio LR(+) = 9.9, LR(-) = 0.4 and accuracy 85.9 %. Results of conventional 2D-MRI were as follows: sensitivity 95 % CI = 10.2 ± 8.5 %, specificity 95 % CI = 96.5 ± 2.5 %, LR(+) = 2.9, LR(-) = 0.9 and accuracy 79.4 %. The diagnostic performance of MRI 3D-Cube was better than conventional 2D-MRI. CONCLUSION The diagnostic performance of MRI 3D-Cube in partial ACL tears was good and significantly better than conventional 2D-MRI. The likelihood of having a positive test was 9.9 times higher in a patient with a partial tear. A negative result did not exclude this diagnosis.

Abstract
INTRODUCTION Bone defects in the humeral head or antero-inferior edge of the glenoid cavity increase recurrence risk following arthroscopic Bankart repair. The present study sought to quantify such preoperative defects using a simple radiological technique and to determine a threshold for elevated risk of recurrence. MATERIALS AND METHODS A retrospective study conducted in two centers enrolled patients undergoing primary arthroscopic Bankart repair for isolated anterior shoulder instability in 2005. The principle assessment criterion was revision for recurrent instability. Quantitative radiology comprised: the ratio of notch depth to humeral head radius (D/R) on AP view in internal rotation; Gerber's X ratio between antero-inferior glenoid cavity edge defect length and maximum anteroposterior glenoid cavity diameter on arthro-CT scan; and the D1/D2 ratio between the glenoid joint surface diameters of the pathologic (D1) and healthy (D2) shoulders on Bernageau glenoid profile views. Seventy-seven patients were included, with a mean follow-up of 44 months (range, 36-54). RESULTS Overall recurrence rate was 15.6%. Recurrence risk was significantly greater when the humeral notch length was more or equal to 20% of the humeral head diameter and the Gerber ratio more or equal to 40%. On Bernageau views, mean D1/D2 ratio was 4.2% (range, 0-23%) in patients without recurrence, versus 5.1% (range, 0-19) in those with recurrence (P=0.003). DISCUSSION Beyond the above thresholds, bone defect as such contraindicates isolated arthroscopic stabilization. The D/R and Gerber ratios are simple and reproducible quantitative measurements can be taken in routine practice, enabling preoperative planning of complementary bone surgery as needed.

Abstract
INTRODUCTION Better outcomes have been reported for two-stage total hip arthroplasty (THA) revision for infection. However, one-stage revision arthroplasty remains an attractive alternative option since it requires only one operation. A decision tree has been developed by the authors in order to determine which type of surgical procedure can be performed safely. The goal of this study was to assess this decision tree for THA replacement in the case of a peri-prosthetic infection. HYPOTHESIS A one-stage procedure may be as successful as a two-stage procedure provided some criteria are fulfilled. METHODS A prospective study included 84 patients, all diagnosed with infected THA who had prosthesis replacement. A one-stage exchange was performed in 38 cases and a two-stage procedure in 46 cases. A two-stage procedure was decided in the case of important bone loss or unidentified germ. Postoperatively, patients received intravenous antibiotics (six weeks), then oral antibiotics (six weeks). The main evaluation criterion was the rate of infection eradication at 2 years minimal follow-up since surgery. If new infection was suspected, a hip aspiration was performed to determine whether it was non-eradication (same germ) or a new re-infection (other germ), which was not considered as a failure. RESULTS The initial infection was cured in 83 out of 84 patients (98.8%), 38 (100%) for the one-stage group and 45 (97.8%) for the two-stage group. Three patients were re-infected with different germs in the two-stage group. Eighty out of 84 (95.2%) patients were infection free, all patients (100%) of the one-stage group and 42 patients (91.3%) of two-stage group. DISCUSSION If some selection criteria were respected, a high success rate in THA replacement for infection may be achieved with a one-stage procedure. It permits to reduce the costs with no loss of chance for the patients. The decision tree was validated. LEVEL OF EVIDENCE Level III; prospective case control study.

Abstract
INTRODUCTION Instability is a major complication after revision total hip arthroplasty. Studies in the literature have shown that the dislocation rate after primary arthroplasties by anterior approach on a fracture table is satisfactory, but the rate of instability following revision surgery is not known. HYPOTHESIS AND AIMS We hypothesized that the Hueter direct anterior approach would result in a lower rate of postoperative dislocation following revision surgery. This hypothesis was tested in a series of isolated acetabular component replacements. PATIENTS AND METHODS Seventy-three consecutive isolated acetabular component replacements were performed between January 2000 and December 2007. Twelve revisions using constrained liners or dual mobility cups were excluded, thus 61 revisions in 59 patients, mean age 65.8-year-old (range 27-86) were included. The indications for revision arthroplasty were: 51 (83.6%) cases of aseptic loosening, five (8.2%) non-integration of cementless cups, three (4.9%) cases of instability, one (1.6%) case of impingement with the psoas and one (1.6%) case of excessive (3cm) lengthening. Acetabular bone defects were moderate, with 12 stage I, 26 stage II, 19 stage III, and only four stage IV defects on the SOFCOT bone stock deficiency score. There was no acetabular reconstruction in 18 cases, while there were four isolated reconstruction cages and 39 cages with a graft. The replacement cup was cemented in 52 cases and cementless in nine. Inclination and anteversion were measured by the Pradhan method on standard X-rays. RESULTS Results were evaluated after a mean follow-up of 2.4 years±1.7 years (1-7 years). Four dislocations were observed (6.6%) all anterior and early in the postoperative period (less than 2 months): three patients had a single episode of dislocation and one patient again underwent revision cup replacement by Hueter anterior approach for recurrent anterior dislocation. The only factor associated with a risk of dislocation was a high body mass index: 29.7±0.8 in the group with dislocation compared to 25.6±3.2 in the group without (P=0.008). A high number of prior interventions was also a significant risk factor (P=0.045). On the other hand, there was no difference in cup inclination or femoral offset between the group with dislocation and that without. DISCUSSION Although the rate of dislocation is higher than after primary THA by anterior approach, it remains acceptable for revision THA and is similar to rates observed with other approaches. The literature does not clearly establish that one surgical approach is better than another in terms of instability. This study was limited by the absence of CT-scan measurements of component orientation both preoperatively to evaluate the femoral component which is preserved, as well as during follow-up to evaluate cup angle and compare the groups with and without dislocation. CONCLUSION The Hueter direct anterior approach is a viable option for isolated cup revision, as long as femoral loosening has been excluded, and the orientation of the preserved femoral component is known.

Abstract
INTRODUCTION Treatment of infection after total hip replacement (THR) is complex and costly. Debridement with component retention is an attractive solution. Success rates in the literature vary widely (18-90%) according to patient selection criteria. The present prospective study assessed the selection criteria used in our department. METHODS A prospective study included all patients (n=210) surgically managed for infection following THR between November 2002 and December 2008. Patients underwent debridement in case of acute infection: i.e., early postoperative infection within 1 month of THR, or secondary hematogenic infection with less than 2 weeks' evolution. Beyond this deadline or in case of implant loosening, implant replacement was performed. The debridement series thus comprised 12 patients (mean age, 69 ± 11.3 years; mean evolution from contamination was 4.8 ± 3.5 days). Bacteriologically adapted antibiotherapy was administered for 6 weeks intravenously followed by 6 weeks per os. Mean follow-up was 40 ± 23 months. No patient was lost to follow-up. The success criterion was apparent eradication of infection at a minimum 2 years, defined by absence of clinical, biological or radiological signs of infection and of death attributable to infection or treatment. Where infection was suspected, hip aspiration or peroperative sampling determined recurrence (identical bacterium) or reinfection (different bacterium). RESULTS There were nine cures (75%) and three failures. Mean Postel Merle d'Aubigné Score, at end of follow-up, was 17 ± 2. The three failures involved the same bacteria (two streptococci [one group B, one group G] and one Enterococcus faecalis) as implicated in the primary infection. DISCUSSION The present results are comparable to those in the literature but poorer than for implant exchange. The technique remains, however, an interesting alternative, allowing less complex surgery and lower cost. CONCLUSION Patient selection criteria need refining so as to increase success rates with this technique. LEVEL OF EVIDENCE Level IV; prospective non-randomized non-comparative study.

Total hip arthroplasty revision due to infection: a cost analysis approach. ORTHOPAEDICS & TRAUMATOLOGY, SURGERY & RESEARCH : OTSR 2010; 96:124-32.

Abstract
INTRODUCTION The treatment of total hip arthroplasty (THA) infections is long and costly. However,the number of studies in the literature analysing the real cost of THA revision in relation to their etiology, including infection, is limited. The aim of this retrospective study was to determine the cost of revision of infected THA and to compare these costs to those of primary THA and revision of non-infected THA. MATERIALS AND METHODS We performed a retrospective cost analysis for the year 2006 using an identical analytic accounting system in each hospital department (according to internal criteria) based on allotment of direct costs and receipts for each department. From January to December 2006, 424 primary THA, 57 non-infected THA revisions and 40 THA revisions due to infection were performed. The different cost areas of the patient's treatment were identified.This included preoperative medical work-up, medicosurgical management during hospital stay,a second stay in an orthopedic rehabilitation hospital (ORH) and post-hospitalisation antibiotic therapy after revision due to infection, as well as home-based hospitalisation (HH) costs, if this was the selected alternative option. We used the national health insurance fee schedule found in the "Common classification of medical procedures" and the "General nomenclature of professional procedures" applicable in France since September 1, 2005. Hospital costs included direct costs (hospital overhead costs) and indirect costs, (medical, surgical, technical settings and net general service expenses). The calculation of HH costs and ORH costs were based on the average daily charge of these departments. The cost of primary THA was used as the reference.We then compared our surgical costs with those found for the corresponding comparable hospital stay groups (Groupes homogènes de séjour). RESULTS The average hospital stay (AHS) was 7.5 +/- 1.8 days for primary THA, 8.9 +/- 2.2 days for non-infected revisions and 30.6 +/- 14.9 days for revisions due to infection. The rate of transfer to a rehabilitation hospital (ORH) was 55% for primary THA, 77% in non infected revision cases and 65% in revisions due to infection. Moreover, 30% of these infected THA were prescribed HH. Non-infected THA revisions cost 1.4 times more than primary THA. THA revisions due to infection cost 3.6 times more than primary THA. DISCUSSION The economic impact of THA infections is considerable. The extra costs are mainly due to an extended hospital stay and to longer rehabilitation consuming significant substantial human and material resources. CONCLUSION The cost of treating infected THA is high. Treatment strategies should therefore be optimised to increase the success rate and minimise total costs. LEVEL OF EVIDENCE Level IV.
