Abstract
The meniscus regeneration can present major challenges such as mimicking tissue microstructuration or triggering cell regeneration. In the case of lesions that require a personalized approach, photoprinting offers the possibility of designing resolutive biomaterial structures. The photo-cross-linkable ink composition determines the process ease and the final network properties. In this study, we designed a range of hybrid inks composed of gelatin(G) and 6-PLA arms(P) that were photo-cross-linked using tyramine groups. The photo-cross-linking efficiency, mechanical properties, degradation, and biological interactions of inks with different G/P mass ratios were studied. The G50P50 network properties were suitable for meniscus regeneration, with Young's modulus of 6.5 MPa, degradation in 2 months, and good cell proliferation. We then confirmed the potential of these inks to produce high-resolution microstructures by printing well-defined microstructures using two-photon polymerization. These hybrid inks offer new perspectives for biocompatible, degradable, and microstructured tissue engineering scaffold creation.

Risk prediction of kalaemia disturbance and acute kidney injury after total knee arthroplasty: use of a machine learning algorithm. Orthop Traumatol Surg Res 2024:103958. [PMID: 39047862 DOI: 10.1016/j.otsr.2024.103958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 05/22/2024] [Accepted: 07/05/2024] [Indexed: 07/27/2024]
Abstract
INTRODUCTION Total knee arthroplasty (TKA) is a procedure associated with risks of electrolyte and kidney function disorders, which are rare but can lead to serious complications if not correctly identified. A routine check-up is very often carried out to assess the seric ionogram and kidney function after TKA, that rarely requires clinical intervention in the event of a disturbance. The aim of this study was to identify perioperative variables that would lead to the creation of a machine learning model predicting the risk of kalaemia disorders and/or acute kidney injury after total knee arthroplasty. HYPOTHESIS A predictive model could be constructed to estimate the risk of kalaemia disorders and/or acute kidney injury after total knee arthroplasty. MATERIAL AND METHODS This single-centre retrospective study included 774 total knee arthroplasties (TKA) operated on between January 2020 and March 2023. Twenty-five preoperative variables were incorporated into the machine learning model and filtered by a first algorithm. The most predictive variables selected were used to construct a second algorithm to define the overall risk model for postoperative kalaemia and/or acute kidney injury (K+ A). Two groups were formed of K+ A and non-K+ A patients after TKA. A univariate analysis was performed and the performance of the machine learning model was assessed by the area under the curve representing the sensitivity of the model as a function of 1 - specificity. RESULTS Of the 774 patients included who had undergone TKA surgery, 46 patients (5.9%) had a postoperative kalaemia disorder requiring correction and 13 patients (1.7%) had acute kidney injury, of whom 5 patients (0.6%) received vascular filling. Eight variables were included in the machine learning predictive model, including body mass index, age, presence of diabetes, operative time, lowest mean arterial pressure, Charlson score, smoking and preoperative glomerular filtration rate. Overall performance was good with an area under the curve of 0.979 [CI95% 0.938 - 1.02], sensitivity was 90.3% [CI95% 86.2 - 94.4] and specificity 89.7% [CI95% 85.5 - 93.8]. The tool developed to assess the risk of impaired kalaemia and/or acute kidney injury after TKA is available on https://arthrorisk.com. CONCLUSION The risk of kalaemia disturbance and postoperative acute kidney injury after total knee arthroplasty could be predicted by a model that identifies low-risk and high-risk patients based on eight pre- and intraoperative variables. This machine learning tool is available on a web platform accessible for everyone, easy to use and has a high predictive performance. The aim of the model was to better identify and anticipate the complications of dyskalaemia and postoperative acute kidney injury in high-risk patients. Further prospective multicentre series are needed to assess the value of a systematic postoperative biochemical work-up in the absence of risk predicted by the model.

A tight anterosuperior intercondylar notch may increase the risk of cyclops syndrome after anterior cruciate ligament reconstruction using a quadruple semi-tendinosus short autograft. Orthop Traumatol Surg Res 2024:103918. [PMID: 38876210 DOI: 10.1016/j.otsr.2024.103918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 09/09/2023] [Accepted: 02/06/2024] [Indexed: 06/16/2024]
Abstract
BACKGROUND Cyclops syndrome is loss of terminal knee extension caused by a fibrous nodule developed in the anterior intercondylar notch. The many known risk factors include preoperative motion-range limitation, tibial tunnel malposition, and tight hamstrings. The primary objective of this study was to assess whether intercondylar notch size was associated with the risk of cyclops syndrome or graft tear after anterior cruciate ligament (ACL) reconstruction using a quadruple semi-tendinosis autograft. The secondary objective was to determine whether intercondylar notch size was associated with functional outcomes. HYPOTHESIS A narrow intercondylar notch is associated with higher risks of cyclops syndrome and poor functional outcomes. METHODS Consecutive patients who underwent ACL reconstruction by quadruple semi-tendinosus autograft were included retrospectively. Preoperative magnetic resonance imaging scans were assessed by a single senior surgeon, who determined the conventional notch width index (NWI) and the anterior NWI (aNWI) for each patient. RESULTS The 120 included patients had a mean follow-up of 2.4±0.8 years. Among them, 20 (16.7%) experienced cyclops syndrome and 7 (5.8%) graft rupture. At last follow-up, 26 (21.7%) had not returned to sports and only 47 (39.2%) had returned to sports at the pre-injury level. The mean Lysholm score was 87.9±13.5 and the main subjective IKDC score was 84±13. A narrow notch was significantly associated with lower likelihoods of returning to sports (p=0.001), returning to the same sport (p<0.0001), and returning to the pre-injury sport level (p=0.004). By multivariate analysis, only the aNWI index was significantly associated with the risk of cyclops syndrome (p<0.0001). An aNWI index lower than 0.18 had 85% sensitivity and 78% specificity for predicting cyclops syndrome. CONCLUSION A narrow anterosuperior intercondylar notch may increase the risk of cyclops syndrome after ACL reconstruction using a quadruple semi-tendinosus graft but is not associated with the risk of graft rupture.

Abstract
PURPOSE Whether photographs included in the operative report of knee arthroscopies can make the surgeon liable in the event of a legal investigation remains unknown. The main objective of this study was to establish inter-observer reliability in determining the presence or absence of lesions of the cartilage, meniscus and anterior cruciate ligament (ACL). Secondary objective was to assess the inter-observer reliability in classifying lesions. METHOD A retrospective observational study was conducted in a continuous serie of 60 patients who underwent knee arthroscopy from the same operator. The photographs of each patient's operative report were presented separately to three experts, blinded to each other. Each expert had to decide on the presence or absence of injuries to the following structures: meniscal, cartilage and ACL and then, classify it. Primary and secondary endpoints were evaluated using the Fleiss' kappa index. RESULTS Inter-observer reliability for lesion detection was between 0.4 and 0.61 for all structures with three exceptions: for cartilage, it was low (0.15) at the lateral tibial plateau and poor (-0.01) at the external condyle. On the contrary, the concordance was almost perfect (0.8) for the ACL. For classifying cartilaginous and meniscal lesions, inter-observer reliability was poor (from 0.03 to 0.14), except for at the lateral meniscus (0.65). CONCLUSION Inter-observer reliability of arthroscopic knee diagnoses is poor when photographs alone are used. In the event of a legal investigation following knee arthroscopy, the photographs included in the operative report should not be used alone to hold the surgeon liable.

Abstract
CONTEXT The distributions and projections of trauma, treated according to the anatomical region, have not been studied in France. The objectives of this study were to obtain French epidemiological data specific to trauma procedures in orthopedic surgery, as well as to establish a statistical trend on the evolution of medical and surgical procedures resulting from this, since 2013 and over the years to come. Our hypothesis was that an increasing trend in trauma procedures since 2013 exists, with an epidemiological forecast of a continuing increase over 50 years, mainly in the context of the management of osteoporotic fractures related to the ageing French population. MATERIAL AND METHODS We conducted a retrospective study using national data to obtain completion of procedures between the start of 2013 and the end of 2021. RESULTS From 2013 to 2021, we noted a total of 5,216,567 procedures related to orthopedic traumatology for an average of 579,618 procedures per year. We noted an overall increase in all procedures, continuing from 2013 to 2019, with an average annual increase of 1.125%. The most commonly performed procedure was osteosynthesis, with an average of 276,989 procedures per year. This was followed by wound sutures with an average of 185,023 procedures, orthopedic reductions of fractures and/or dislocations at an average of 62,960, then arthroplasties with 25,425 procedures per year, musculotendinous ruptures were 19,755 procedures per year, surgical reductions of fractures and/or dislocations represented 6920 procedures per year, and fasciotomies with 2848 procedures. From 2013 to 2021, there was an annual average of 276,989 osteosynthesis procedures. Open osteosynthesis, with an average of 146,547 procedures per year, represented 55% of osteosynthesis procedures. Fractures of the proximal end of the femur represented 79,549 procedures on average per year, including 46,621 (58%) involving the trochanter, while 32,852 (41%) were of the femoral neck. Wrist fractures accounted for an annual average of 55,300. Hand fractures represented an annual average of 38,444, of which 52.2% were closed (17,778). On average, 1000 fractures per year involved the carpus without scaphoid involvement, and 2177 scaphoid fractures. Ankle fractures represented 37,951 procedures on average per year, including 74% of the malleolar complex (28,199). Leg fractures represented 17,613 procedures per year, 58% tibial diaphysis (10,091), 41% tibial plateau (6,857). The strengths of this study are the exhaustiveness of the data, presenting all the Common Classification of Medical Procedures (CCAM) chosen during the defined period. CONCLUSION This study allowed us to establish, to our knowledge, the first epidemiological database of French orthopedic traumatology. LEVEL OF EVIDENCE IV; epidemiological descriptive study.

Orthop Traumatol Surg Res 2024; 110:103794.

Abstract
BACKGROUND Treatment protocols, including anesthesia, are constantly progressing to improve rapid early postoperative recovery in lower-limb arthroplasty. To the best of our knowledge, however, no studies compared general versus spinal anesthesia (GA vs. SA) in the surgical pathway of patients undergoing total knee or hip arthroplasty (TKA, THA). Better knowledge of the processes should improve efficacy in theater and optimize surgical planning. The present study comparing GA and SA in the operating room aimed to assess (1) theater occupancy times, and (2) times for each step in a surgery day according to type of anesthesia. HYPOTHESIS SA leads to longer theater occupancy than GA in TKA and THA. METHODS A single-center retrospective case-control study analyzed data for the period January 2019 to December 2020 in 303 TKAs (100 GA, 203 SA) and 277 THAs (143 GA, 134 SA), comparing times for all perioperative steps and particularly theater occupancy. RESULTS In TKA, occupancy did not differ between GA and SA: 98±16min versus 98±14min respectively; Δ=0min (p=0.78). In THA, occupancy was shorter with SA than GA: 117±23min versus 123±26min respectively; Δ=-6min (p=0.02). In THA, time to perform SA was longer than induction of GA: 28±13min versus 23±12min respectively; Δ=+5min (p<0.001). In TKA, time to leaving the operating room was shorter with SA than GA: 8±5min versus 14±7min respectively; Δ=-6min (p<0.001). DISCUSSION/CONCLUSION SA did not involve longer mean theater occupancy than GA for TKA, and reduced it by 6minutes for THA. LEVEL OF EVIDENCE III; case-control study.

Abstract
The rate of refractory chronic pain after total knee replacement (TKR) is 20-25%, with no identifiable etiology in 6% of cases. Without an etiologic diagnosis, the surgeon is unlikely to consider revision, but pain poses a therapeutic challenge for achieving satisfaction and an acceptable quality of life. Genicular nerve radiofrequency ablation (GNRFA) was recently developed as a non-drug analgesic option. It is minimally invasive and safe, with few adverse effects, opening a new perspective for management of refractory chronic pain after TKR. LEVEL OF EVIDENCE: IV.

Abstract
Drainage after total hip or knee arthroplasty (THA, TKA) used to be systematic to prevent complications and notably hematoma and infection. However, improvement in practices, the introduction of blood-sparing protocols and above all the conclusions reported in many studies have cast doubt on this dogma. There is abundant literature on the pros and cons of drainage after primary THA and TKA. The main endpoints were transfusion rates and volumes, total blood loss and variations in hemoglobin levels. Clinical endpoints comprised pain, edema, postoperative hematoma and, more rarely, short-to-medium-term function. Except for a few studies reporting greater pain and edema without drainage, there is agreement that drainage not only provides no benefit but actually aggravates postoperative bleeding. There are fewer studies of drainage in revision procedures for the hip and very few for the knee. The interest of drainage has not been demonstrated and again postoperative bleeding is aggravated. Whether in primary or revision arthroplasty, tranexamic acid is recommended when not contraindicated, whatever the administration protocol. However, it should not be seen as the sole and determining reason for abandoning drainage. LEVEL OF EVIDENCE: V, expert opinion.

Abstract
INTRODUCTION Unicompartmental knee arthroplasty (UKA) and valgus high tibial osteotomy (HTO) are two options for isolated medial femorotibial osteoarthritis in genu varum. In the absence of registries for osteotomies and for arthroplasty in the knee, epidemiological data are hard to obtain in France. We therefore performed a retrospective study, with the aims of: 1) estimating UKA and HTO survival without revision by total knee arthroplasty (TKA), and 2) assessing risk factors for revision according to treatment group. HYPOTHESIS Medium-term survival is better with HTO than UKA in under-70-year-olds. MATERIALS AND METHOD All elderly patients undergoing HTO or UKA in the French National Hospitals Database for the period 2011-2020 were included: i.e., 108,007 patients; 43,537 HTO (29,330 male, 14,207 female; mean age 49.7 years, 95% CI 49.6-49.8) and 64,470 UKA (31,181 male, 33,289 female; mean age 60.5 years, 95% CI 60.5-60.6). RESULTS Survival free of revision by TKA was 75.8% (95% CI=75.2-76.4) for UKA and 80.6% (95% CI=80.0-81.3) for HTO (p<0.00001). In UKA, revision risk factors comprised: low annual center volume (<17 UKAs per year) (HR=1.50; 95% CI=1.41-1.59), obesity (HR=1.25; 95% CI=1.18-1.32), and age <60years, with maximum risk for 50-59years (HR=2.41; 95% CI=1.83-3.16 in 50-59 year-olds). In HTO, revision risk factors comprised: obesity (HR=1.42; 95% CI=1.31-1.53), rheumatoid arthritis (HR=2.75; 95% CI=1.37-5.51), joint chondrocalcinosis (HR=2.01; 95% CI=1.18-3.39), and age >60years (HR=8.81; 95% CI=7.23-19.73 in 60-69-year-olds). Male gender was a protective factor against revision in both groups: UKA, HR=0.75 (95% CI=0.72-0.79); HTO, HR=0.73 (95% CI=0.69-0.77). The number of UKAs increased over the years, matching the increase in arthroplasty in France, with a decrease in HTOs until 2019. CONCLUSION HTO showed better medium-term survival than UKA in under-70-year-olds in France. Even so, indications decreased in favor of UKA, although the respective risk factors differ. These findings suggest that conservative surgery still has a role, depending on osteoarthritis stage. LEVEL OF EVIDENCE III; retrospective comparative study.

Growth progression of anterior cruciate ligament bone grafts in a pediatric population: magnetic resonance imaging analysis. Pediatr Radiol 2023; 53:2369-2379. [PMID: 37592189 DOI: 10.1007/s00247-023-05725-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/16/2023] [Accepted: 07/17/2023] [Indexed: 08/19/2023]
Abstract
BACKGROUND In children, the incidence of anterior cruciate ligament (ACL) ruptures and reconstructions has significantly risen. Unfortunately, re-rupture rates following surgery are substantially higher in children than adults. Previous research suggests that smaller graft diameters are predictive of re-rupture. OBJECTIVE This study aimed to investigate the growth progression of the ACL bone graft, specifically in terms of width and length, within the intra-articular portion and tunnels, using successive magnetic resonance imaging (MRI) scans. The hypothesis was that the ACL grafts would undergo thinning during growth. MATERIALS AND METHODS The cohort comprised 100 patients who underwent ACL reconstruction. Among them, 37 patients with significant residual growth were selected for analysis. Of these, 4 patients experienced graft rupture, 5 had "over-the-top" techniques, 12 had missing MRI scans and 5 were lost to follow-up. Each included patient underwent two MRI scans; the analyses of which were conducted in a double-masked manner. RESULTS A total of 13 knees (and patients) were analyzed, with a mean ± SD (range) delay of residual growth between the two MRI scans of 3.3 + / - 1.4 (1.2-5.2) years. The graft exhibited elongation, thinning and eventual integration with the surrounding bone in the tunnels. Within the intra-articular portion, the mean [95% CI] increase in graft size between the two MRI scans was 30.8% in length and 14.8% in width. The width/length ratio in the intra-articular part was 20.4% on the first MRI and 20.8% on the second MRI. Since this difference in the ratio (+ 0.4%) was not statistically significant (P=0.425), our results indicate that the grafts remained stable in terms of proportions without thinning or thickening. Therefore, the initial hypothesis was validated for the tunnel portion but not the intra-articular portion of the grafts. CONCLUSION In children with open physes, ACL grafts demonstrate smooth growth progression in all dimensions. However, this finding does not fully explain the high rate of re-rupture observed in children. Further research is needed to elucidate the underlying factors contributing to re-rupture in this population.

Effects of tele-prehabilitation on clinical and muscular recovery in patients awaiting knee replacement: protocol of a randomised controlled trial. BMJ Open 2023; 13:e073163. [PMID: 37793919 PMCID: PMC10551960 DOI: 10.1136/bmjopen-2023-073163] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 08/31/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND The increasing prevalence of knee osteoarthritis and total knee arthroplasty (TKA) impose a significant socioeconomic burden in developed and developing countries. Prehabilitation (rehabilitation in the weeks immediately before surgery) may be crucial to prepare patients for surgery improving outcomes and reducing assistance costs. Moreover, considering the progress of telemedicine, candidates for TKA could potentially benefit from a tele-prehabilitation programme. We aim to evaluate the effects of a home-based tele-prehabilitation program for patients waiting for total knee replacement. METHODS AND ANALYSIS Forty-eight male patients, aged 65-80, on a waiting list for TKA will be recruited and randomly assigned to the tele-prehabilitation intervention or control groups. Both groups will undergo the same 6-week exercise program (five sessions/week) and the same educational session (one per week). The tele-prehabilitation group will perform asynchronous sessions using a tablet, two accelerometers and a balance board (Khymeia, Padova, Italy), while the control group will use a booklet. The Western Ontario and McMaster Universities Osteoarthritis Index Questionnaire, at the end of the prehabilitation, will be the primary outcome. Secondary outcomes will include self-reported outcomes, performance tests and change in expressions of blood and muscle biomarkers. Ten healthy subjects, aged 18-30, will be also recruited for muscle and blood samples collection. They will not undergo any intervention and their data will be used as benchmarks for the intervention and control groups' analyses. ETHICS AND DISSEMINATION This randomised controlled trial will be conducted in accordance with the ethical principles of the Declaration of Helsinki. This study has been approved by the Ethics Committee of Vita-Salute San Raffaele University (Milan, Italy. No. 50/INT/2022). The research results will be published in peer-reviewed publications. TRIAL REGISTRATION NUMBER NCT05668312.

Orthop Traumatol Surg Res 2023; 109:103506. [PMID: 36496160 DOI: 10.1016/j.otsr.2022.103506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 08/01/2022] [Accepted: 08/22/2022] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Arthroscopic lateral meniscus repair is performed in the "figure-of-4 position" (supine, with the affected knee flexed and the lower leg crossed over the extended contralateral leg), and anchorage is often on the popliteal tendon. Extending the limb at the end of the procedure alters the relations between the popliteal tendon and the repaired meniscus. The present study aimed to assess lateral meniscal suture fixation on the popliteal tendon after a cycle of flexion-extension. HYPOTHESIS Extending the knee can induce suture release. TYPE OF STUDY Cadaver study. MATERIALS AND METHODS Twenty-two fresh adult human cadaver knee specimens were used. Under arthroscopy with all-inside implants, a vertical suture onto the popliteal tendon was performed through the lateral meniscus. Suture status was assessed under arthroscopy after a cycle of flexion-extension, and deemed defective if the suture was sufficiently loose for the arthroscope to be able to be passed through the popliteal hiatus, if the stitch had passed through the meniscus, or if the suture was broken. RESULTS Thirteen sutures (59.1%) remained well fixed, and 9 (40.1%) were defective: 4 (18.2%) were loose, in 4 (18.2%) the stitch had passed through the meniscus, and in 1 (4.5%) the suture had broken. CONCLUSION In a population of elderly cadaver knee specimens, arthroscopic suture of the lateral meniscus to the popliteal tendon was defective after flexion-extension in 40% of cases. Stress seems to be exerted on the suture when extension is resumed. Thus, a single stitch seems insufficient for stable lateral meniscus repair. CLINICAL IMPLICATIONS Suture of the lateral meniscus to the popliteal tendon undergoes stress when extension is resumed, potentially causing failure of lateral meniscus repair. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND One issue in total knee arthroplasty (TKA) is management of preoperative flexion contracture, which may be associated with poor functional outcome. AIM The aim of this study was to compare functional results in TKA with or without preoperative flexion contracture, treated according to a standardized algorithm of tissue release and bone cut. PATIENTS AND METHOD A single-center retrospective case-control study was performed on prospectively collected data for the period 1987-2016. Patients with >10̊ flexion contracture were assigned to the "contracture" group and associated to a selected control group at a ratio of 1:4. Clinical analysis used pre and post-operative International Knee Society (IKS) scores. The significance threshold was set at p<0.05. RESULTS Eight hundred and forty-nine cases and 3,304 controls were included, comprising a total of 2,838 male and 1,315 female participants. Mean preoperative extension deficit was 13̊±6̊ in the contracture group and 1̊±2̊ in controls. Preoperative IKS total and functional scores were significantly poorer in the contracture group (38±18 and 54±20) than in controls (52±16 and 59±19) (p<0.001). Postoperatively, the two groups did not significantly differ in IKS functional score (77±22 vs. 79±21, p=0.143). There were differences in IKS knee score (87±12 vs. 88±13, p=0.006) and maximal flexion (114̊±14̊ vs. 119̊±13̊, p<0.0001) that were statistically, but not clinically, significant. DISCUSSION A systematic standardized algorithm for surgical treatment of flexion contracture during primary total knee arthroplasty provided clinical outcomes similar to those of patients without preoperative flexion contracture.

Orthop Traumatol Surg Res 2023; 109:103463. [PMID: 36374765 DOI: 10.1016/j.otsr.2022.103463] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 06/03/2022] [Accepted: 06/09/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND The number of Total Knee Arthroplasty (TKA) procedures has been rising steadily for several decades in Europe and the USA. The increase varies in pace across countries, with a gradual climb in northern and central Europe, a slowing in the USA, and an exponential surge in the UK. In France, a 32.2% rise in the number of TKA and unicompartmental knee arthroplasty procedures was documented between 2012 and 2018. However, no study has focussed specifically on changes in both TKA procedures and the features of TKA patients. The objective of this study was to use the French national healthcare database to evaluate (1) increases in TKA procedures according to sex and age, (2) whether TKA is being performed at increasingly younger ages, (3) whether the comorbidity profile at TKA is changing, and (4) whether the TKA incidence rate will stabilise in the future, with a projection for 2050. HYPOTHESIS In France, the number of TKA procedures is rising in both males and females but the pace of the increases differs between sexes. MATERIAL AND METHOD This study used data collected in France in 2009-2019, separately for different age groups and for males and females, in the French national healthcare database (Système national des données de santé, SNDS) that collects information on all surgical procedures performed nationwide. Based on information about the TKA procedures, we determined (1) the TKA incidence rates with their time trends and (2) indirectly, the comorbidity profiles of the patients at TKA. Linear, Poisson, and logistic models were built to predict incidence rates in 2030, 2040, and 2050. RESULTS Between 2009 and 2019, the TKA incidence rate showed a steeper increase in males than in females (from 71.2 to 122.9 [+73%] vs. 124.2 to 181.0 [+46%], respectively). Although this increase was replicated in all age groups, it was sharper in patients younger than 65 years, in both males and females (from 20.9 to 37.9 [+82%] and 33.6 to 51.3 [+53%], respectively). During the study period, the number and proportion of patients increased in the group with mild comorbidities (from 40 093 to 67 430 TKAs, i.e., from 53.1% to 65.7% of all TKAs) but not in the other comorbidity groups. All projection models were validated. Nonetheless, the most likely scenario, provided by the logistic model, is a 33% rise by 2050 in both males and females (i.e., to 151 575 TKA procedures) with a plateau starting around 2030. CONCLUSION Although the increase in TKA procedures is more marked in males than in females, the trends are similar in both sexes, with a sharper rise in the group younger than 65 years and a shift toward patients with milder comorbidities. In the longer term, incidence rate trends follow logistic dynamics, with a plateau starting around 2030. To meet the increasing demand, a corresponding development in relevant healthcare resources must be planned. LEVEL OF EVIDENCE IV, descriptive epidemiological study.

Abstract
INTRODUCTION When medial knee osteoarthritis continues to get worse after a high tibial osteotomy (HTO) procedure, a subsequent total knee arthroplasty (TKA) is typically warranted. Medial unilateral knee arthroplasty (UKA) is not recommended. The aim of this study was to evaluate the outcomes of patients who underwent medial UKA after HTO. HYPOTHESIS Good results can be obtained with this procedure, as long as the postoperative valgus is not excessive. MATERIALS AND METHODS This was a retrospective, single-center study of patients operated between January 2005 and June 2019. The primary endpoint was the Oxford Knee Scale (OKS). The Knee injury and Osteoarthritis Outcome Score (KOOS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC), range of motion and complications were the secondary endpoints. The average follow-up was 79 months. RESULTS Forty-one knees in 38 patients were analyzed. Four revisions with implant exchange (10%) were needed. Thirty-seven knees had a mean OKS of 20/60±8 (12-39). The mean flexion and extension amplitude were 123°±8° (110-140) and -1.5°±4 (-15-0), respectively. Eight patients had flexion and/or extension contractures. DISCUSSION Good functional and clinical outcomes in the medium term were achieved for the patients in this study who underwent UKA after HTO. These findings reinforce the good results reported in recent studies of UKA after HTO. LEVEL OF EVIDENCE IV, Retrospective study.

Abstract
BACKGROUND Realignment osteotomies is gaining popularity amongst Dutch orthopaedic surgeons. Exact numbers and used standards in clinical practice concerning osteotomies are unknown due to the absence of a national registry. The aim of this study was to investigate the national statistics of performed osteotomies, utilized clinical workups, surgical techniques, and post-operative rehabilitation standards in the Netherlands. METHOD Dutch orthopaedic surgeons, all members of the Dutch Knee Society, received a web-based survey between January and March 2021. This electronic survey contained 36 questions, subdivided into: general surgeon-related information, number of performed osteotomies, inclusion of patients, clinical workup, surgical techniques, and post-operative management. RESULTS 86 orthopaedic surgeons filled in the questionnaire, of whom 60 perform realignment osteotomies around the knee. All the 60 responders (100%) perform high tibial osteotomies and 63.3% additionally perform distal femoral osteotomies, while 30% perform double level osteotomies. Discrepancies in surgical standards were reported regarding to inclusion criteria, clinical workup, surgical techniques, and post-operative strategies. CONCLUSIONS In conclusion, this study got more insight in knee osteotomy clinical practices as applied by Dutch orthopaedic surgeons. However, there are still important discrepancies which pleads for more standardization based on available evidence. A (inter)national knee osteotomy registry, and even more so, a (inter)national registry for joint preserving surgeries could be helpful to achieve more standardization and treatment insights. Such a registry could improve all aspects of osteotomies and its combinations with other joint-preserving interventions towards evidence for personalised treatments.

Orthop Traumatol Surg Res 2023; 109:103581. [PMID: 36796624 DOI: 10.1016/j.otsr.2023.103581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 11/17/2022] [Accepted: 11/30/2022] [Indexed: 02/16/2023]
Abstract
INTRODUCTION Unicompartmental knee arthroplasty (UKA) is a reliable and reproducible procedure. While some surgeons have incorporated it into their therapeutic armamentarium, others do not use it routinely, leading to a large disparity in practice. The objective of this study was to investigate in France the epidemiology of UKA from 2009 to 2019 to identify: (1) the evolution of growth trends by sex and age, (2) the evolution of the state of comorbidity of patients during the operation, (3) the evolution of trends according to the regions, (4) the projection best suited to the observations at 2050. HYPOTHESIS Our hypothesis was that in France, an increase would be observed over the period studied, differing according to the characteristics of the population. MATERIALS AND METHOD The study was conducted in France over the 2009-2019 period for each gender and age group. The data was taken from the NHDS (National Health Data System) database, which includes all the procedures carried out in France. Based on the collection of procedures performed, the incidence rates (per 100,000 inhabitants) and their evolution were deduced, as well as the indirect assessment of the patient's comorbidity status. Using linear, Poisson, and logistic projection models, incidence rates were projected to the years 2030, 2040, and 2050. RESULTS Between 2009 and 2019, the incidence rate of UKA increased sharply (from 12.76 to 19.57; +53%), the growth was different in men (from 10.78 to 20.34; +89%) and women (from 14.61 to 18.85; +29%). The male/female sex ratio increased from 0.69 in 2009 to 1.0 in 2019. The increase was greatest among men under 65 (from 4.9 to 9.9; +100%) and lowest among women over 75 (from 41.2 to 40.5; -2%). Over the period studied, the proportion of patients with mild comorbidities (HPG1) increased (from 71.7% to 81.1%) at the expense of the other classes with more severe comorbidities. This dynamic was observed for all age groups: 0-64 years (from 83.3% to 90%), 65-74 years (from 81.4% to 88.4%), 75 years and over (38 .2% to 52.6%) regardless of sex. There was a strong disparity between the regions with a change in the incidence rate ranging from -22% (from 29.8 to 23.1) for Corsica to +251% (from 13.9 to 48.7) for Brittany. The proposed projection models suggested an increase in the incidence rate of +18% in logistic regression, +103% in linear regression by 2050. DISCUSSION Our study showed strong growth in the number of UKAs in France over the period studied, being highest in young men. The proportion of patients with fewer comorbidities increased for all age groups. A disparity in inter-regional practice was identified, with indications that remain ambiguous and differ according to the practitioner. We can expect continued growth in the years to come, adding to the care burden. LEVEL OF EVIDENCE IV; Descriptive epidemiological study.

Orthop Traumatol Surg Res 2023; 109:103577. [PMID: 36754168 DOI: 10.1016/j.otsr.2023.103577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 11/18/2022] [Accepted: 11/30/2022] [Indexed: 02/10/2023]
Abstract
BACKGROUND Return to sport after Knee Arthroplasty has been investigated reporting modifications in the physical activities with a trend towards to lower impact sports after Unicompartemental Knee Arthroplasty. The purpose of this study was to analyze the return to sport level after medial unicompartmental knee arthroplasty (MUKA) in a population of osteoarthritic patients having practiced impact sport, defined with a University of California at Los Angeles activity scale (UCLA)≥9 in their pre-symptomatic arthritic period. HYPOTHESIS Return to an impact sport after MUKA was possible for a population of osteoarthritic patients having practiced impact sport in their pre-symptomatic arthritic period. METHODS Ninety-two MUKA with a pre-symptomatic arthritic UCLA score≥9, including 60 men (65.2%) and operated between January 2009 and September 2014, were evaluated by a dedicated survey. Informations were obtained concerning the physical activities (intensity, frequency, kind of sport, reasons to decrease or stop the physical activities in the pre- and the postoperative period). The average age was 64.9 years±6.4 (range 49-74.4). Three different periods were compared: pre-symptomatic arthritic, preoperative and postoperative period. The mean follow-up was 7.3±1.7 years. RESULTS The mean pre-symptomatic arthritic UCLA score was 9.9±0.3, the mean preoperative UCLA score was 7.0±2.5 (2-10) and the mean postoperative UCLA score was 7.2±2.0 (3-10). There were significant differences for the mean UCLA score values between pre-symptomatic arthritis and postoperative UCLA scores (p=0.034), however no difference was detected in mean score values before and after surgery (p=0.09). Only 32.6% (30/92) of patients had a postoperative UCLA score≥9. For patients practicing an impact sport activity (UCLA≥9) in the preoperative period (23/92; 25%), the postoperative UCLA score was at 8±1.1 (range 4-10). In this subgroup, 47.8% (11/23) of patients had a postoperative UCLA score≥9. The decline in sports in postoperative was predominantly explained by residual pain of the operated knee (31/92; 34%), precaution to not damage the prosthesis (25/92; 27%) and restrictions due to another joint (19/92; 21%). DISCUSSION Return to impact sport after MUKA seems to be limited to a restrained number of patients. The main reasons to the decline in sporting activity level are linked to the residual pain of the operated knee and the precaution to not damage the prosthesis.

J Orthop 2023; 36:99-105. [PMID: 36659901 PMCID: PMC9842961 DOI: 10.1016/j.jor.2023.01.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/13/2022] [Accepted: 01/04/2023] [Indexed: 01/09/2023] Open
Abstract
Introduction Postoperative outcomes following total shoulder arthroplasty can be affected by preoperative health factors such as tobacco usage. Methods The charts of patients who underwent anatomic total shoulder arthroplasty were retrospectively analyzed and stratified based on smoking status. The primary data included range of motion and patient reported outcomes. Additionally, demographic, radiographic, and survivorship analyses were conducted. All data were analyzed using statistical inference. Results There were 78, 49, and 16 non-smoker, former smoker, and current smoker shoulders respectively with no significant differences in sex, American Society of Anesthesiologists status, body mass index, or mean follow-up time (average: 10.7 yrs). Smokers (51.5 ± 10.4 years) were younger than both non-smokers (64.9 ± 8.1 years; p < 0.01) and former smokers (65.1 ± 9.1years; p < 0.01) at the time of surgery. For non-smokers and former smokers, all range of motion and patient reported outcome scores significantly improved. Smokers reported significant improvements in all patient reported outcomes and external and internal rotation. Visual Analog Scale, American Shoulder and Elbow, and Simple Shoulder Test scores were lower for smokers comparatively, but these differences did not reach significance. Forward elevation was higher postoperatively for non-smokers (149.7o ± 17.2o) and former smokers (147.1o ± 26.0o) compared to current smokers (130.9o ± 41.2o; p = 0.017). No differences between the cohorts were found in the radiographic analysis. Revision rates were lower in the non-smoking cohort (7.7%) compared to both former (20.4%; p = 0.036) and current smokers (37.5%; p < 0.01). Survival curves showed that non-smoker implants lasted longer than those of current smokers. Conclusion After a decade, patients generally had improved shoulder range of motion, functionality, and pain regardless of smoking status. However, current smokers required shoulder replacements sooner and revision surgery more frequently.

Orthopaedic and trauma surgery in France: Do patterns differ across healthcare institution types (public community, public university, private not-for-profit, and private for-profit)? Orthop Traumatol Surg Res 2022; 108:103402. [PMID: 36108820 DOI: 10.1016/j.otsr.2022.103402] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 09/21/2021] [Accepted: 11/04/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND No studies have evaluated, to our knowledge, potential differences in practices in France according to type of healthcare institution, i.e., university public hospital, community public hospital, or private hospital with or without participation in the public healthcare system. The objectives of this study of the exhaustive information collected in the French hospital-admission database were to: (1) describe the numbers of the main procedures performed in France by orthopaedic and trauma surgeons in each type of institution and each subspecialty; and (2) to determine whether the pattern of procedures differed according to the type of healthcare institution. HYPOTHESIS Differences in surgical practice patterns exist across healthcare institution types and according to the nature of the procedures. PATIENTS AND METHODS A retrospective observational nationwide study was performed using the exhaustive French hospital database. All surgical procedures done in 2019 for orthopaedic and trauma indications were collected. We then classified the procedures according to the most common diagnoses by distinguishing procedures on the hip, knee, shoulder, hand, spine, ankle, and foot, as well as paediatric and traumatology procedures. RESULTS Procedures performed more often in private institutions included those on the hip (93,225 [64.3%] of 144,919), knee (223,542 [75.5%] of 296,255), shoulder (103,923 [76.6%] of 300,577), hand (408,035 [77.6%] of 525,534), spine (for degenerative disease, 27,001 [71.2%] of 37,915), and ankle and foot (75,392 [77.1%] of 105,720). In contrast, of the 19,157 (80.3%) of the 23,848 paediatric procedures and 203,090 (67.7%) of the 300,065 traumatology procedures were done in public institutions. For all eight comparisons, the difference between public and private institutions was statistically significant. The overall trend was towards public university hospitals performing more paediatric and trauma procedures and more complex surgeries such as those required by multiple traumatic injuries. DISCUSSION Our study provides accurate numbers of surgical procedures done in public and private healthcare institutions in France in 2019. We found major differences not only across categories and specialties but also within specialties depending on the type of procedure. Orthopaedic surgical activity shows a marked imbalance in France between public and private institutions. Further research would be needed to identify the causes.

Abstract
BACKGROUND Loosening remains one of the most common reasons for revision total knee arthroplasty (TKA). Cement viscosity has a potential role in reducing revision rates for loosening. The aim of this study was to assess the outcome for loosening of the 5 most used cemented knee prostheses by constraint type, based on the cement viscosity type used. METHODS There were 214,708 TKA procedures performed between 1999 and 2020 for a diagnosis of osteoarthritis using the 5 most commonly used minimally stabilized, posterior stabilized, and medial pivot design cemented tibial components. Only procedures with a cemented tibial component were included. Outcomes for two different cement viscosities, 140,060 high viscosity and 74,648 low viscosity cement, were compared for each fixation type within each of the three stability groups. RESULTS There was no difference in a risk of all-cause revision when high viscosity cement was used compared to low viscosity cement for minimally stabilized prostheses (hazards ratio [HR] 1.07 [95% CI 0.99-1.15], P = .09), posterior stabilized prostheses (HR 1.03 [95% CI 0.95-1.11], P = .53), and medial pivot design prostheses (HR 1.06 [95% CI 0.80-1.41], P = .67). No difference was observed between cement viscosity types for any of the prosthesis constraint types when aseptic loosening was assessed. CONCLUSIONS We found no difference in the risk of revision for any reason, or for loosening, with cement viscosity for the most commonly used minimally stabilized, posterior stabilized, and medial pivot TKA. The role of cement viscosity in the risk of TKA revision remains unclear and further research is required. LEVEL OF EVIDENCE Level III Retrospective comparative study.

Abstract
INTRODUCTION Revision of total knee arthroplasty (rTKA) for suspicion of metal hypersensitivity (MHS) may require hypoallergenic implants. Results for coated implants have not been reported. The aim of the present study was to assess short-term results and survival of rTKA for MHS using a multilayer implant coating. HYPOTHESIS Multilayer implant coating improves functional results in rTKA, with survival comparable to primary coated implants. MATERIAL AND METHODS A single-center retrospective observational study included 28 patients (30 knees) undergoing rTKA for MHS using a coated implant between May 2011 and November 2016. Exclusion criteria comprised implant malpositioning and history of infection in the affected knee. Clinical and radiological results were assessed on the International Knee Society (IKS) and SF-36 functional scores and Ewald radiological score. Survival was calculated on Kaplan-Meier estimation. RESULTS Mean follow-up was 3.8 years. Mean IKS score increased by 40.2 points (40%) [range, 28.1-52.3] (p<0.05). Mean range of motion increased by 17° [range, 9.5-24.5°] (p<0.05). Mean physical and mental SF-36 components were respectively 44.7 and 46.1. Survivorship was 93%. DISCUSSION There was significant functional improvement after rTKA for MHS. There were no short-term complications related to the zirconium nitrate coating. However, studies with longer follow-up will be needed for confirmation. LEVEL OF EVIDENCE IV; retrospective study.

Abstract
BACKGROUND The long-standing radiograph (LSR) is the reference tool for assessing knee alignment after total knee arthroplasty (TKA). However, its value is debatable, as many factors can influence measurement accuracy. Computer-assisted surgery (CAS) provides accurate measurements. Few studies have compared LSR and computer-assisted measurements of knee alignment. The objective of this study was to compare hip-knee-ankle (HKA) angle values obtained before and after TKA on LSRs to those obtained during CAS. HYPOTHESIS The HKA angle values measured on LSRs before and after surgery are identical to those measured during CAS. MATERIAL AND METHODS The HKA angles of 126 knees were measured on bipedal full-weight-bearing LSRs obtained before and 3 months after TKA. The results were compared to the values obtained during CAS. RESULTS Before surgery, the standard deviation was 2.672, with limits of agreement of {-5.391; + 5.082}. The intra-class coefficients were good for the overall measurements (0.9), good for detecting>10° varus (0.89), fair for<10° varus and valgus (0.66 and 0.71, respectively), poor for>10° valgus (0.43) and poor for normal alignment (0). Post-operatively, the standard deviation was 3.113, with limits of agreement of {-6.426; +5.776}. The intra-class coefficient was poor for the overall measurements (0.20), negative for normal alignment (-0.05) and<10° valgus (-0.05), and positive for<10° varus (0.017) and for>10° varus and valgus (0.33). CONCLUSION Before TKA, the LSR overestimates the deformity compared to CAS. After surgery, the two methods are not comparable. These findings underline the relevance of routinely obtaining LSRs and for using LSR results to estimate costs for healthcare insurance reimbursement purposes.

Ramp lesion repair via dual posteromedial arthroscopic portals: A cadaveric feasibility study. Orthop Traumatol Surg Res 2022; 108:103175. [PMID: 34906726 DOI: 10.1016/j.otsr.2021.103175] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 01/16/2021] [Accepted: 01/18/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Ramp lesions are found in 16% to 40% of patients undergoing anterior cruciate ligament reconstruction. The repair technique traditionally involves using a suture hook through a posteromedial portal, with the arthroscope positioned in the intercondylar view via an antero-lateral portal. Ramp lesions may be difficult to visualize and repair, even with a 70° arthroscope. The objective of this study was to assess the feasibility of suturing ramp lesions via dual posteromedial portals for the arthroscope and instruments. HYPOTHESIS Dual posteromedial arthroscopic portals allow good visualisation and high-quality suturing of ramp lesions, without inducing specific iatrogenic injuries. MATERIAL AND METHODS We used 11 fresh cadaver knees. Two posteromedial portals were created under visualisation via an arthroscope introduced through an antero-lateral portal: one was the traditional instrumental portal and the other, located more proximally, was the optical portal. A 2-cm long ramp lesion was created. A suture hook was used to place one or two stitches of PDS n°0 suture. A probe was used to test the quality and stability of the suturing. The posteromedial plane was then dissected to evaluate the anatomical relationships of the portals. RESULTS The dual posteromedial approach allowed the visualisation and hook suturing of the ramp lesions in all 11 cases. A single stitch was placed in 4 cases and two stitches in 7 cases. The suture was always of good quality and stable when tested with the probe. The dissection found no injuries to nerves, blood vessels, or tendons. CONCLUSION Ramp lesions can be repaired through a dual posteromedial arthroscopic approach. This surgical technique provides good visibility of these lesions and allows high-quality suturing, with no specific iatrogenic injuries. It is an alternative to ramp lesion repair via a single posteromedial portal, which can be challenging. LEVEL OF EVIDENCE IV, experimental study with no control group.

Kim H, Kim JM, Bin SI, Lee BS. Radial tears in the anterior third of the lateral meniscus are frequently combined with horizontal tears. Orthop Traumatol Surg Res 2022; 108:103223. [PMID: 35104626 DOI: 10.1016/j.otsr.2022.103223] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 03/11/2021] [Accepted: 03/17/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Radial tears of the lateral meniscus are often located in the junction of the middle and posterior third or posterior tibial attachment. However, we observed that a few cases of radial tears occurred in the anterior third of the lateral meniscus, and in many cases, they were accompanied by horizontal tears. HYPOTHESIS Radial tears are more frequently accompanied by horizontal tears in the anterior third of the lateral meniscus than in other regions. MATERIAL AND METHODS From July 2006 to May 2019, patients who underwent arthroscopic surgery for radial tears of the lateral meniscus were included. Patients with radial tears in the anterior third of the lateral meniscus were classified into the anterior group and those with radial tears in the middle and posterior third were classified into the comparison group. Magnetic resonance imaging and arthroscopic findings were reviewed to evaluate whether radial tears were accompanied by other types of tears, especially horizontal tears. The incidence of complex tears between the two groups was compared. RESULTS Eighty knees in 79 patients were included. The mean age at the time of surgery was 44.1±16.9 years. The anterior group included 30 knees, and 19 (63.3%) of those also had horizontal tears. In the anterior group, all complex tears were accompanied by horizontal tears, and no other types of accompanying tears were observed. The comparison group included 50 knees, and 16 (32%) of those also had other types of tears. Of the 16 complex tears, 14 had horizontal tears and 2 had longitudinal tears. The incidence of complex tear was significantly higher in the anterior group than in the comparison group (p<.001). CONCLUSION Radial tears occurring at the anterior third of the lateral meniscus are frequently accompanied by a horizontal tear. It is important to be aware and predict the occurrence of such characteristic tears and to do proper surgical procedures. LEVEL OF PROOF IV; Cross-sectional study.

Orthop Traumatol Surg Res 2022; 108:103264. [PMID: 35248790 DOI: 10.1016/j.otsr.2022.103264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 11/22/2021] [Accepted: 12/09/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Residual laxity can persist after anterior cruciate ligament (ACL) reconstruction. This increased anterior translation can be measured with a knee arthrometer. Nevertheless, the measurement parameters and functional impact of this residual laxity are not well understood. The aims of this study were to (1) evaluate the effect of applying loads of 134N, 200N and 250N on the measured residual laxity after ACL reconstruction and (2) evaluate the prognostic ability of the various measurement parameters on the functional outcomes. HYPOTHESIS After ACL reconstruction, the functional outcomes will be correlated to the postoperative residual laxity. METHODS We did a prospective study of 61 recreational athletes who underwent surgical reconstruction of their ACL with the Kenneth-Jones technique between 2016 and 2019. The mean age of these patients was 27±7 years, and most were men (75%). The side-to-side difference in laxity was measured pre- and postoperatively using the GNRB® arthrometer at three load levels: 134N, 200N and 250N. The functional outcomes were determined based on the return to sports and the KOOS, IKDC and ARPEGE scores. The mean follow-up was 30±10 months. RESULTS Half the patients had returned to sport at their pre-injury levels, while 25% had returned to a lower level and 25% had stopped doing any physical activity. At 134N, a 1-mm increase in side-to-side difference was associated with a 2-fold higher risk of not returning to sports (OR 2; 95% CI 1.22-3.23; p<0.01). At 200N, a 1-mm increase in side-to-side difference was associated with a 50% higher probability of having a poor/fair ARPEGE score (OR 1.5; 95% CI 1.05-2.02; p=0.02). At 200N, a 4-mm side-to-side difference was the prognostic threshold for failure to return to sports with a positive predictive value of 86% and specificity of 98%. CONCLUSIONS This case series found a strong correlation between residual laxity and the functional outcomes after ACL reconstruction. A threshold of 4mm residual laxity evaluated on the GNRB® at 200N was predictive of adverse outcomes and failure to return to sports in our population of recreational athletes.

Orthop Traumatol Surg Res 2022; 108:103254. [PMID: 35183758 DOI: 10.1016/j.otsr.2022.103254] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 11/07/2021] [Accepted: 12/09/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION The clinical diagnosis of an anterior cruciate ligament (ACL) tear is based on 3 tests: anterior drawer, pivot shift and Lachman. The latter is the most commonly used test. The "lever sign" is a new clinical test that was first described by Lelli et al. in 2014. The primary objective of this study was to determine the sensitivity of the lever sign test for the clinical diagnosis of ACL tears, in the primary care setting of patients with acute knee injuries. Primary care being the first point of contact between patients and the healthcare system (general practitioners in this study). The secondary objective was to calculate the positive predictive value (PPV) of the lever sign test, by comparing it to the PPV of the Lachman test and its sensitivity. The working hypothesis was that the sensitivity of the lever sign test was equal to or greater than 80%. METHODS This prospective cohort study included patients with ski-related knee injuries which occurred in French ski resorts between December 1, 2019, and March 15, 2020. The Lachman test and the lever sign test were performed by 36 mountain physicians and were compared to the magnetic resonance imaging (MRI) findings. The lever sign test involved placing a closed fist under the patient's calf in the supine position and applying downward pressure over the quadriceps. Depending on whether the ACL was intact or not, the patient's heel would either rise off the examination table or remain still. This study included 258 patients: 190 women and 68 men. RESULTS The MRIs found 219 ACL tears and 36 intact ACLs. Three MRIs were deemed uninterpretable. The sensitivity of the lever sign test was 61.2% and the PPV was 83.8%. The sensitivity of the Lachman test was 99.1% and the PPV was 86.5%. CONCLUSION This study determined the sensitivity of the lever sign test for the clinical diagnosis of ACL tears during real-life situations encountered by mountain physicians. This sensitivity was lower than expected. The Lachman test, on the other hand, showed a very high sensitivity. It remains the test of choice for the clinical diagnosis of ACL tears in patients with knee injuries. Therefore, the lever sign test can complement the Lachman test but is not a substitute for it.

Psychological Patient-reported outcome measure after anterior cruciate ligament reconstruction: Evaluation of subcategory in ACL-Return to Sport after Injury (ACL-RSI) scale. Orthop Traumatol Surg Res 2022; 108:103141. [PMID: 34763076 DOI: 10.1016/j.otsr.2021.103141] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/11/2021] [Accepted: 02/15/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND It has been recognized that psychological factors influence the return to sports after anterior cruciate ligament reconstruction (ACLR). The ACL-return to sports after injury (RSI) scale was developed based on subcategories of emotions, confidence in physical performance and risk appraisal. However, it has not been clarified describing which is the most influential psychological factor of the ACL-RSI scale. HYPOTHESIS Risk appraisal is the most influent for return to sports in the subcategories of the ACL-RSI scale. PATIENTS AND METHODS A total of 85 competitive patients who had undergone ACLR were evaluated at 6, 12 and 24 months after surgery. They were classified the return to sports (RTS) group and non-return to sports (NRTS) group. Evaluations were several clinical and functional scores including Cincinnati knee rating system, Knee Osteoarthritis Outcome Score (KOOS), Lysholm score, limitation in activities of daily living (ADL) and sports which estimated by Visual Analog Scale (VAS) score, Isokinetic Muscle Strength (quadriceps and hamstrings), single hop test and anterior laxity. They were investigated their relationship with the ACL-RSI scale including each subcategory. RESULTS The total ACL-RSI scale significantly improved at each point. Of the subcategories, only risk appraisal was not significantly different at each point (p=0.21 and p=0.13). There was a significant difference at 24 months after ACLR between the RTS group and NRTS group. In terms of risk appraisal, compared with emotion and performance confidence, the difference in the mean value was the most divergent (RTS group: 55.9±22.7 and NRTS group: 23.8±19.3) and took time to improve through 24 months. Among various clinical and functional scores, there were significant differences in the VAS score for sports, KOOS-symptoms, sports and QOL, Cincinnati Knee Rating System-cut, and single hop test values between two groups. Of these, the KOOS-QOL and VAS score for sports showed particularly strong correlations with ACL-RSI risk appraisal (r=0.75 and -0.68, respectively). CONCLUSION Of the ACL-RSI scale, risk appraisal took the longest time to improve and strongly affected the return to sports. The KOOS-QOL and VAS score for sports were most strongly correlated with the ACL-RSI risk appraisal. It seems that it is important to reduce the psychological risk as soon as possible after ACL injury in ACLR patients. LEVEL OF EVIDENCE II.

Development and Evaluation of the Anterior Cruciate Ligament Injury Score (ACLIS). Orthop Traumatol Surg Res 2022; 108:103257. [PMID: 35219887 DOI: 10.1016/j.otsr.2022.103257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 09/19/2021] [Accepted: 10/05/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Knee ligament sprains are a common reason for emergency-room visits. Initially, the often difficult physical examination provides limited information, creating a risk of missing cruciate-ligament injuries, which can result in substantial functional impairments. No simple tool is available to emergency and primary-care physicians for decisions regarding specialist referral of patients with knee ligament sprains. An easy to use clinical score for the emergency setting would help identify patients at high risk of anterior cruciate ligament (ACL) tears after knee ligament sprains. The primary objective of this study, in two separate cohorts with acute knee injuries, was to develop, then validate a score for assessing the probability of ACL tear and, therefore, the need for specialist referral. HYPOTHESIS A score based on patient-interview information with a cut-off associated to good sensitivity and positive predictive value (PPV) for ACL tears can be developed. MATERIAL AND METHODS A literature review identified seven items to be used in the score: pivoting and contact activity at the time of injury, perceived cracking sound, sensation of dislocation, joint effusion, suggestive mechanism, inability to resume the activity, and immediate sensation of instability upon walking. To select the most relevant items, we recruited a development cohort of 228 patients (127 males and 101 females) with a mean age of 32±9 years who were seen for knee injuries between November 2017 and November 2018 at three healthcare institutions; 183 (80%) had ACL tears. The score was then tested in a validation cohort of 121 patients (79 males and 42 females) with a mean age of 28±2.5 years seen at two healthcare institutions between November 2019 and November 2020; 81 (67%) had ACL tears. In all patients, the diagnosis of ACL tear was confirmed by a specialist examination and magnetic resonance imaging. RESULTS Four items proved both sensitive and specific for ACL injury and were combined into the score: an immediate sensation of knee instability, an inability to resume the sports activity, a sensation of dislocation, and injury during a pivoting-contact activity. Patient report of two or more of these four criteria had 96% sensitivity and 66% specificity for ACL tear, with a PPV of 91% and an NPV of 83%. Results were similar in the validation cohort, confirming that a cut-off of at least two of the four items strongly suggested an ACL tear, with 94% sensitivity, 56% specificity, a PPV of 82% and an NPV of 82%. CONCLUSION The ACLIS score performs well for the emergency-room diagnosis of ACL tear, with 95% sensitivity, 62% specificity, an 88% PPV, and an 82% NPV. Patients with ACLIS scores of 2 or more probably require specialist referral with or without magnetic resonance imaging. The ACLIS score could be used routinely in emergency departments to decrease the proportion of patients with undiagnosed ACL tears.

Return to work after primary total hip or knee arthroplasty. First French study. Retrospective study of 241 cases. Orthop Traumatol Surg Res 2022; 108:103163. [PMID: 34863957 DOI: 10.1016/j.otsr.2021.103163] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 04/24/2021] [Accepted: 09/16/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION The quality and reliability of the results of primary total hip or knee arthroplasty (THA, TKA) have allowed indications to be extended to younger, working-age patients, raising the issue of return to work. This question has never been specifically addressed in THA and TKA in a French population. We therefore conducted a retrospective study to determine: (1) the rates and intervals of return to work, and (2) factors affecting return to work and reasons for non-return. HYPOTHESIS Rates and intervals of return to work are comparable to those in Western countries as a whole: 1.1-10.5 weeks in THA and 8-12 weeks in TKA. MATERIAL AND METHOD A single-center retrospective study included patients aged under 65 at surgery, between 2009 and 2013. A questionnaire collected population and occupational data. The patients' occupational situation was collected at a minimum 1 year postoperatively. During the study period, 289 TKAs or THAs were performed; 241 patients were recontacted, 144 of whom had been working at the time of surgery: 72 THAs and 72 TKAs. The sex-ratio was well balanced: 69 males, 75 females. Mean age was 55.8±8 years (range, 18.6-65.7 years). The mean time from surgery to data collection was 34.5 months (95% CI, 32.2-36.8 months). RESULTS In all, 86 patients (57.6%) returned to work, at a mean 124 days (range, 15-540 days; 95% CI, 102.8-144.4 days). At 3 months, 55.4% of patients (n=46) had returned to work, and 97.6% (n=81) at 12 months. In most cases, patients returned to the same occupation. CONCLUSION The study hypothesis was not confirmed. French primary THA or TKA patients returned to work later and less frequently than in other Western countries. LEVEL OF EVIDENCE IV, retrospective study without control group.

Abstract
PURPOSE The objective of this study was to determine the reasons for complaints and describe the judicial means upstream of France's courts following arthroscopy. METHODS This is a retrospective observational study including all compensation records related to arthroscopic surgery, collected from the two leading French insurance organizations: MACSF and Branchet companies, from 2014 to 2018. Three medical experts performed the protocol and analysis. RESULTS Finally, 247 procedures were included. The most common motives were: the appearance or persistence of pain (43.7%), postoperative infection (29.1%), technical errors (10.5%), nerve damage (5.7%), arterial lesions (2.8%), side errors (2.4%). Knee arthroscopies were more at risk of legal action for infection (p = 0.0006), and for disappointing results or persistent pain (p = 0.001). The first recourse was the conciliation and compensation commission (CCI) in 136 cases (55.1%), the civil court (TGI) in 88 cases (35.6%) and amicable settlement in 23 cases (9.3%). The mean time between surgery and the complaint was 32.8 ± 25.7 months, and was shorter in the case of an amicable procedure (p < 0.001). The lawsuit's mean duration was 15.6 ± 11.2 months, but longer in case of civil proceedings (p < 0.0001). The experts found no negligence in 81.8% of cases (n = 202). Infections were the leading cause of recourse to the conciliation and compensation commission (p < 0.0001), while technical errors were the main reason for complaints settled in an amicable procedure (p = 0.035). It was found more proven negligence in case of amicable procedures (p < 0.0001). The mean amount of compensation was 60,968.45€. No significant difference could be found regarding the median values of compensation between the reason of complaint. The amount of compensation was higher in civil court proceedings than in any others (p = 0.02). CONCLUSION The main reasons for arthroscopy litigation in France are reported in this study, specifying how they are managed upstream of possible legal proceedings. The knee is the main joint involved. Patient information, close follow-up associated with early and appropriate management of complications are the main ways to reduce complaints.

Abstract
BACKGROUND The use of morphometric implants in total knee arthroplasty (TKA) has shown better early clinical outcomes compared to conventional implants. The primary objective of this study is to evaluate the functional outcome and the implant survivorship of a morphometric TKA at a minimum of 5 years of follow-up. METHODS From May 2012 to June 2015, all patients undergoing primary TKA with a single design of morphometric posterior-stabilized prosthesis (Persona; Zimmer) in a prospective observational single-center study were evaluated. The Knee Society Scoring System (KSS) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) were completed preoperatively, 1, 3, and 5 years postoperatively. Kaplan-Meier was used to calculate survivorship of the implants. The average follow-up was 75 months. RESULTS In total, 237 TKAs were performed in 235 patients with a mean age of 73 years (49-90). The KSS Knee Score increased from 44.7 (13-64) preoperatively to 93.6 (71-100), the KSS Function Score from 45.8 (17-69) to 92.2 (51-98), and the KSS Satisfaction Score from 26.6 (16-51) to 41 (35-55) at 5 years of follow-up. Similarly, for the KOOS score, a significant improvement of all the subscales was observed at 5 years of follow-up. Implant survival without reoperation at 5 years of follow up was 98.72% (95% confidence interval 0.95-1.00). CONCLUSION This is the first study demonstrating that significant improvements of the functional scores with good survivorship can be achieved at a minimum of 5 years of follow-up with TKA using morphometric implants.

Abstract
BACKGROUND There are a number of factors that influence blood loss during and after primary total knee arthroplasty (TKA) and revision TKA (rTKA). The purpose of this study was to provide a factorial assessment that would aid surgeons in managing expected blood loss in rTKA, when compared to TKA. The first question asked was the blood loss and transfusions between TKA and rTKA and the second question was risk factors for blood loss after rTKA. HYPOTHESIS Blood loss in any rTKA is higher than in TKA by a factor of 2. PATIENTS AND METHODS A retrospective single-centre consecutive series of rTKA between 2006 and 2018 was performed. Based on the rTKA types identified in joint registries, 4 rTKA cohorts were created: aseptic minor rTKA, aseptic major rTKA, 1st stage, and 2nd stage septic rTKA. A consecutive TKA cohort from the same study period was used to create a propensity score matched cohort with the aseptic major rTKA cohort. RESULT A total of 622 rTKA were identified. Aseptic major rTKA had double the median blood loss than TKA. The lowest blood loss was observed in the TKA group followed by aseptic minor rTKA, and the highest in 2nd stage septic rTKA. The median total blood loss was higher in all rTKA by a factor ranging between 1.38 and 2.17. Higher age, female gender, lower preoperative hemoglobin, chronic heart disease and history of myocardial infarction were risk factors for increased blood loss. The type of rTKA performed was not predictive of blood loss in the linear regression analysis. DISCUSSION Blood loss after rTKA is 1.38 to 2.17-fold higher than after TKA. The blood loss observed in 2nd stage septic rTKA and aseptic major rTKA was the highest. Older female patients, with a low preoperative hemoglobin, were identified to be at the highest risk of blood loss after rTKA. Strategies for further blood loss reductions need to be utilised to the fullest extent for these procedures. LEVEL OF EVIDENCE III; retrospective prognostic study.

Abstract
INTRODUCTION The number of hinged total knee arthroplasty (HTKA) procedures is constantly increasing. There are two hinge types: central (CHTKA) and posterior (PHTKA). The primary purpose of the study was to compare implant survival in patients with CHTKA versus PHTKA. The secondary purpose was to analyse the radiological and clinical results of the implants. HYPOTHESIS There is no difference between the two groups. MATERIALS AND METHODS This study involved 53 patients who received a HTKA for either primary, trauma or revision surgery, of these 32 were in the CHTKA group and 21 in the PHTKA group, with a mean age of 69 years (38-89). The exclusion criteria were: etiology of sepsis, incomplete records and refusal to use data. The revision rate, with the replacement of prosthetic components, was the primary endpoint. The secondary outcomes were: mobility, complications, VAS, IKS, Devane, Charnley and Oxford knee scores, and radiological progression. RESULTS The mean follow-up was 51 months (1-139). At 60 months, overall survival rate of the HTKA was 81%, with a confidence interval (CI) of 95% (71-93.2), and there was no difference between CHTKA and PHTKA, 77.7% (95% CI, 63.3-95.4) versus 85.7% (95% CI, 72-100), p=0.625, respectively. Flexion was 101°±15 (80-140) for CHTKA versus 98°±12 (30-130) for PHTKA, p=0.006. VAS was 0.5±16 (0-6) for CHTKA versus 1.6±14 (0-4) for PHTKA, p=0.000008. The IKS was 103±39 (15-180) for CHTKA versus 81±51 (9-200) for PHTKA, p=0.03. There were no differences in either radiological progression, complications or other functional scores. DISCUSSION No significant difference was observed between the survival of CHTKA and PHTKA. CHTKA had better flexion, reduced VAS and increased IKS. Surgeons should be aware of these findings and apply careful consideration to their choice of hinge. LEVEL OF EVIDENCE IV; retrospective single-centre study.

Implementation and results of an enhanced recovery (fast-track) program in total knee replacement patients at a French university hospital. Orthop Traumatol Surg Res 2021; 107:102851. [PMID: 33578042 DOI: 10.1016/j.otsr.2021.102851] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 10/05/2020] [Accepted: 10/12/2020] [Indexed: 02/03/2023]
Abstract
INTRODUCTION In total knee replacement (TKR) surgeries, "fast-track" or enhanced recovery after surgery (ERAS) programs are being developed, but their impact on care pathway quality and safety has not been fully explored in the French literature. The present study aimed to compare results in TKR between fast-track and conventional pathways, addressing the following questions: (1) Are 90-day rates of complications, readmission and surgical revision higher with fast-track? (2) Is mean length of stay (LoS) shorter with fast-track? (3) Are postoperative pain and clinical results improved by fast-track? And, (4) are patients and care staff satisfied with these new programs? HYPOTHESIS Implementing fast-track for TKR in a university hospital center is beneficial for the patient and does not impair the quality and safety of care. PATIENTS AND METHOD A case-control study was performed using a retrospective analysis of prospectively collected data. A fast-track program was implemented for TKR by modifying the care pathway. This involved instituting a therapeutic education consultation, optimizing blood sparing, modifying surgical practices, and hastening early mobilization thus actively involving patients in their own management. Between January 2017 and January 2019, 216 patients with a mean age of 69.23±7.80years and mean BMI of 30.15±4.79kg/m2 were included in the fast-track group, with 335 matched patients included in the conventional group. RESULTS At 90days, there were no significant inter-group differences in rates of infection (fast-track=1.39%, conventional=0.90%; p=0.34), readmission (fast-track=3.24%, conventional=3.58%; p=0.49), or surgical revision (fast-track=2.78%, conventional=2.69%; p=0.298). The visual analog scale (VAS) pain rating was 1.56±1.36 in the fast-track group versus 5±2.41 in the conventional group; p<0.001. LoS was 3.17±1.59days in fast-track versus 7.25±1.85days in the conventional group; p<0.001. Ninety-five percent of patients and 96% of care staff were satisfied with the fast-track program. DISCUSSION Fast-track implementation ensured quality and safety of care; it did not increase the rate of complications in primary TKR. Mean length of stay was drastically reduced. Both patients and care staff were very satisfied with these new procedures. LEVEL OF EVIDENCE III; case-control study.

Trabecular Metal Cones Combined With Short Cemented Stem Allow Favorable Outcomes in Aseptic Revision Total Knee Arthroplasty. J Arthroplasty 2021; 36:657-663. [PMID: 32978026 DOI: 10.1016/j.arth.2020.08.058] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 08/26/2020] [Accepted: 08/28/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The purpose of this study was to compare the functional outcomes and implant survivorship at a minimum of 5 years of follow-up of several reconstruction techniques with or without metaphyseal cone and stems of variable length. METHODS A retrospective comparative matched analysis was performed from 2 prospectively collected databases. Only patients who underwent revision total knee arthroplasty procedures for aseptic causes using a single design of rotating hinge knee with a minimum of 5 years of follow-up were analyzed. Patients were separated into 3 groups: trabecular metal (TM) cones + short cemented stems (TM + short stem [SS]), TM cones + long uncemented stems (TM + long stem [LS]), and no cone (NC) + long uncemented stems (NC + LS). A matching process based on age (±5 years) was realized. RESULTS About 99 patients were included; 33 in the TM + SS group, 33 in the TM + LS group, and 33 in the NC + LS group. The mean time of follow-up was 9.3 years. A significant difference of the improvement of subscale pain, symptom, activities of daily living, quality of life of the Knee Injury and Osteoarthritis Outcome score and knee, function of the Knee Society Score was observed in favor of TM + SS group compared with the 2 other groups. At 8 years of survivorship, the components free of revision for any cause were 90.9% for the TM + SS group, 84.9% for the TM + LS group, and 90.6% for the NC + LS group. CONCLUSION The use of a short cemented tibial stem combined with a TM cone in revision total knee arthroplasty offers identical survival rate with better functional outcome compared with the use of a long uncemented stem associated with TM cones or metallic augments at a minimum of 5 years of follow-up.
