RESUMEN
PURPOSE: An arthroscopic partial meniscectomy (APM) for degenerative meniscus lesions and traumatic meniscus tears are two distinct entities and their long-term outcomes are rarely reported. The aim of this review was to compare the long-term (clinical and radiological) results of APM performed on stable knees for traumatic tears (TT) or degenerative lesions (DL). METHODS: Pubmed, Scopus and Embase databases were searched to identify relevant studies published between 2010 and 2023 using the keywords 'meniscectomy' OR 'meniscectomies' OR 'meniscal resection'. English-language, Levels I-IV evidence studies reporting either radiographic or clinical outcome measures with a minimum of 6 years' follow-up after APM were included. Studies including discoid meniscus, open meniscectomy, unstable knee and combination with other procedures were excluded. To rate the quality of evidence, the methodological index for non-randomized studies was used. RESULTS: Thirty-two studies were included, with follow-up periods ranging from 6 to 22 years. Eleven studies dealt with TT with a mean age of 31.5 ± 6.6 years and a mean follow-up of 11.6 ± 6.9 years. At the last follow-up, radiographic osteoarthritis (OA) ranged from 36% to 76%, with an average rate of 48 ± 19%; functional scores ranged from 71 to 97, with a mean of 90 ± 4 for the Lysholm score, 86 ± 10 for the International Knee Documentation Committee (IKDC) and 94 ± 16 for the knee injury and osteoarthritis outcome (KOOS). Twenty-one studies dealt with DL with a mean age of 49.9 ± 7.2 years and a mean follow-up of 14.9 ± 6.3 years. At the last follow-up, radiographic OA ranged from 23% to 97%, with an average rate of 77 ± 28%; functional scores ranged from 40 to 87, with a mean of 79 ± 10 for the Lysholm score and 71 ± 16 for the IKDC. CONCLUSION: Ten-year clinical outcomes of APM are better for TTs when compared to DLs. Rates of OA are difficult to compare but lower for TTs. LEVEL OF EVIDENCE: Level IV.
RESUMEN
BACKGROUND: Proximal femur fractures constitute a public health concern given their high frequency and the aging population. The frequency of a contralateral fracture occurring can reach up to 15% of cases. Certain historical or demographic factors constitute risk factors for refracture, but the type of fracture, either of the femoral neck (FN) or pertrochanteric (PT), cannot be predicted. The objectives of this retrospective study were: firstly, to analyze several anatomical markers in order to determine whether they predispose to a certain type of fracture in the event of contralateral refracture, and secondly, to determine the predictive power of these possible radiological markers for the type of contralateral fracture. HYPOTHESIS: The hypothesis was that the "Neck shaft ratio" (NSR) and the "Intertrochanteric distal ratio" (ITDR) made it possible to determine a proximal femoral morphology at risk of FN and/or PT fracture in the event of a second fracture. MATERIAL AND METHODS: This continuous retrospective single-center series from January 2011 to December 2019 of patients who presented with bilateral fractures of the proximal femurs was analyzed. Radiographs, taken after the first fracture, of the contralateral femur were studied. Morphological measurements previously described in the literature were carried out as well as the NSR (ratio of the medial cortical thicknesses of the femoral neck at its narrowest and basicervical level) and the ITDR (ratio of the medial diaphyseal cortical thicknesses at 5mm and 20mm from the distal portion of the lesser trochanter). One hundred and twenty-six patients were included: 46/126 (36.5%) had bilateral FN, 50/126 (39.7%) bilateral PT and 30/126 (23.8%) one of each. RESULTS: Only NSR and ITDR were significant predictive measures for FN or PT fracture type [0.54±0.11 vs. 0.81±0.16 (p<0.0001) and 0. 85±0.1 vs. 0.68±0.1 (p<0.0001), respectively]. These two ratios had an excellent predictive value for the type of fracture occurring on the contralateral side [NSR: AUC ROC = 0.91 (95% CI; 0.86-0.96); ITDR: AUC ROC = 0.81 (95% CI; %, 0.74-0.89)]. The NSR had excellent intra- and inter-observer reproducibility with an interclass correlation coefficient of 0.93 [95% CI: 0.86-0.97] and 0.91 [95% CI: 0.82-0.96] respectively, the same also applied for the ITDR with interclass correlation coefficient values of 0.93 [95% CI: 0.87-0.97] and 0.86 [95% CI: 0.73-0.93] respectively. DISCUSSION: The NSR and ITDR ratios offer a simple and reproducible means to predict a morphological predisposition to a certain fracture type, respectively an FN and PT on the side contralateral to an initial osteoporotic proximal femur fracture. A prospective cohort study would be useful in defining a possible prognostic nature on the occurrence and/or time until refracture. LEVEL OF EVIDENCE: III; retrospective control case.

INTRODUCTION: The appropriateness or necessity of patellar resurfacing in total knee arthroplasty (TKA) is not clearly established. The objective of the present study was to compare the clinical and functional results of patients with bilateral involvement, operated on in one knee by TKA with patellar resurfacing and in the other knee by TKA without resurfacing. The hypothesis was that there was no difference in results between the two sides. METHOD: This was a retrospective cohort of patients operated on by TKA without patellar resurfacing in a second osteoarthritic knee after contralateral TKA with patellar resurfacing. Twenty consecutive patients who underwent second primary TKA constituted their own control group (40 knees). Iwano scores were comparable. Mean age was 75.9±6.2years. Mean time between the two procedures was 20.6±11.9months. RESULTS: There were no differences in SF-36, KOOS or Lille patellofemoral scores between the right and left knees. Sixty-five percent of patients were unable to differentiate the performance of their knees in activities of daily living. CONCLUSION: The present study did not differentiate results according to patellar resurfacing, showing the limitations of resurfacing for early functional gain after primary TKA. Resurfacing might thus not be essential, even if it was performed in replacement of the first knee. LEVEL OF EVIDENCE: IV; retrospective cohort study.
RESUMEN
INTRODUCTION: Multiligament knee injury with posteromedial laxity is serious and usually requires surgery. Reconstruction is preferable to repair. The main aim of the present study was to report clinical results and laximetry for an original posteromedial corner (PMC) allograft reconstruction technique known as The Versailles Technique. The secondary aim was to determine prognostic factors for surgery. The study hypothesis was that anatomic PMC reconstruction by tendon allograft provides satisfactory medium-term clinical and laximetric results. METHODS: A retrospective study assessed postoperative clinical and laximetric results after PMC allograft reconstruction at a minimum 12 months' follow-up. Laxity was assessed on comparative bilateral stress X-rays, and functional results on the International Knee Documentation Committee (IKDC) score, the Lysholm score and the Knee injury and Osteoarthritis Outcome Score (KOOS). RESULTS: Twenty-six patients were included between 2013 and 2019. Mean follow-up was 27.4±9 months. Mean subjective IKDC score was 69.21±17.36, mean Lysholm score 77.78±14.98 and mean KOOS 66.44±18.52. OBJECTIVE: IKDC results were 77% grade A, 22% grade B, and 0% grade C or D. Mean medial differential laxity in forced varus was 0.83±1.26mm. Mean subjective IKDC scores were poorer in Schenck KD-III than KD-I (p=0.03). Functional results were comparable with acute and with chronic laxity. Age correlated inversely with median KOOS (p=0.009). There was no correlation between postoperative radiologic laxity in forced varus and functional results. DISCUSSION: Versailles anatomic PMC allograft reconstruction for acute or chronic posteromedial knee laxity showed medium-term efficacy in restoring good objective and subjective stability. LEVEL OF EVIDENCE: IV; retrospective observational study.

INTRODUCTION: Associations between obesity and knee osteoarthritis or complications after total knee arthroplasty (TKA) are well established. The procedure can significantly improve knee function, favoring weight loss, despite the risk of surgical complications. The main objective of the present study was to assess change in body mass index (BMI) after TKA in patients with severe or morbid obesity (BMI≥35kg/m2). The secondary endpoint was the rate of surgical revision. The hypotheses were that there is no significant change in BMI after TKA and that there is a significant rate of revision. METHODS: This retrospective descriptive study was conducted for the period June 2009 to December 2019. Thirty-three patients (48 knees) were included: 27 women, 6 men; mean age, 66.5 years (range, 55-80). Preoperatively, 11 patients had BMI 35-39.9kg/m2 and 22 BMI≥40 (including 11 with BMI≥45kg/m2). The preoperative axis was in varus for 35 patients (73%, including 54%≥10°) and in valgus for 13 (27% including 33%≥10°). Radiological and clinical evaluation was carried out at 3 months and 1 year postoperatively. At≥2 years, change in BMI and EQ5D functional score were established by telephone survey; >5% change in BMI was considered significant. RESULTS: Mean follow-up was 6.9±2.3 years (range, 2.9-10.5). Twenty-five patients (38 knees) were included for analysis. Mean postoperative BMI was 41±5kg/m2, with a mean decrease of 1.2±3.6kg/m2. At the last follow-up, BMI had increased in 8 patients (32%), including 3 by >5% (12%), and decreased in 16 (64%), including 7 by >5% (28%). The higher the baseline BMI, the greater the decrease: for BMI [35-39.9], -0.81 (range, -6.8; +4.3); for BMI [40-44.5],-1 (range, -9; +5.22); and for BMI>45, -1.54 (range, -3.97; +1.3). EQ5D averaged 0.75 at last follow-up. The higher the preoperative BMI, the more satisfactory the postoperative EQ5D: EQ5D for BMI [35-39.9]=0.71 (range, 0.36; 1); for BMI [40-44.5]=0.75 (range, 0.45; 1); and for BMI>45=0.80 (range, 0.48; 1). Four early surgical site infections (10.5%) and 2 isolated changes of the tibial component for early loosening (5.2%) required surgical revision. CONCLUSION: Patients with severe or morbid obesity had a low tendency to lose weight after TKA, but this does not appear to us to be clinically relevant: the functional results were good. Nevertheless, this series showed a significant rate of revision (15%). TKA was feasible in patients with BMI≥35kg/m2, but requires appropriate patient information. LEVEL OF EVIDENCE: IV.

PURPOSE: The aim of this ESSKA consensus is to give recommendations based on scientific evidence and expert opinion to improve the diagnosis, preoperative planning, indication and surgical strategy in Anterior Cruciate Ligament revision. METHODS: Part 2, presented herein, followed exactly the same methodology as Part 1: the so-called ESSKA formal consensus derived from the Delphi method. Eighteen questions were ultimately asked. The quality of the answers received the following grades of recommendation: Grade A (high level scientific support), Grade B (scientific presumption), Grade C (low level scientific support) or Grade D (expert opinion). All answers were scored from 1 to 9 by the raters. Once a general consensus had been reached between the steering and rating groups, the question-answer sets were submitted to the peer-review group. A final combined meeting of all the members of the consensus was then held to ratify the document. RESULTS: The review of the literature revealed a rather low scientific quality of studies examining the surgical strategy in cases of ACL reconstruction failure. Of the 18 questions, only 1 received a Grade A rating; 5, a Grade B rating; and 9, grades of C or D. The three remaining complex questions received further evaluations for each portion of the question and were looked at in more detail for the following grades: B and D; A, C and D; or A, B, C and D. The mean rating of all questions by the rating group was 8.0 + - 1.1. The questions and recommendations are listed in the article. CONCLUSION: ACL revision surgery, especially the surgical strategy, is a widely debated subject with many different opinions and techniques. The literature reveals a poor level of standardization. Therefore, this international European consensus project is of great importance and clinical relevance for guiding the management of ACL revision in adults. LEVEL OF EVIDENCE: Level II.

PURPOSE: The purpose of this study was to: 1/ describe the characteristics of a cohort of patients over 75 years of age hospitalized in perioperative geriatric units (UPOG) for iterative fractures; 2/ investigate the risks of institutionalization related to the first fracture; and 3/ search for potential risk factors for iterative fracture. METHODS: This is a retrospective single-center study analyzing patients over 75 years old, hospitalized in UPOG. RESULTS: Of the 3207 patients hospitalized, 292 patients had a refracture (9.1%), with a mean age of 85.4+/-5.8 years. Initial fractures were mainly intertrochanteric (43.2%) and the femoral neck (32.9%). Refractures occurred mainly in the first year (55.5%), with a median delay of 9.6 months. Refractures were mainly intertrochanteric (29.5%), periimplant (prosthesis, osteosynthesis) (28.8%), and femoral neck (26.7%). Dementia was the only factor for institutionalization after the first fracture episode (p = 0.0002). Proximal femoral fracture (PFF) and female gender were risk factors for iterative fracture (10.2% vs. 6.8%, p = 0.003; 10.7% vs. 6.8%, p = 0.005 respectively), but not age (85.4 vs. 85.8 years, p = 0.24). PFF were more likely to result in the same fracture type in the second episode (58.1% vs 7.1%, p<0.0001). The time to refracture was shorter in case of periimplant fracture (p = 0.0002), or discharge directly to home (p = 0.04). CONCLUSION: PFF and female gender are risk factors for recurrent fracture, which is even more likely to occur early in case of home discharge or periimplant fracture.
RESUMEN
BACKGROUND: Young surgeons are taught that genu valgum deformity is associated with hypoplasia of the lateral femoral condyle, despite the absence of supporting evidence. The objective of this study was to determine whether the lateral condyle was hypoplastic in genu valgum, by assessing the morphological features of the distal femur and their variations according to the severity of the coronal deformity. HYPOTHESIS: The lateral femoral condyle is not hypoplastic in genu valgum deformity. MATERIAL AND METHODS: The 200 included patients treated by unilateral total knee arthroplasty were divided into five groups based on their preoperative hip-knee-ankle (HKA) angle. The HKA angle, valgus cut angle (VCA), and anatomical lateral distal femoral angle (aLDFA) were measured on long-leg radiographs. Computed tomography images were then used to measure the medial and lateral anterior-posterior condylar lengths (mAPCL and lAPCL) and condylar thicknesses (mCT and lCT), distal femoral torsion (DFT), medial and lateral posterior condylar heights (mPCH and lPCH), and medial and lateral condylar volumes (mCV and lCV). RESULTS: No significant differences were demonstrated across the five mechanical-axis groups for mAPCL, lAPCL, mCT, lCT, mPCH, or lPCH. The groups differed significantly regarding the VCA (p<0.0001), aLDFA (p<0.0001), DFT (p<0.0001), and mCV/lCV ratio (p<0.0001). VCA and aLDFA were smaller when the valgus exceeded 10°. DFT was similar in all varus knees (2.2°-2.6°) but significantly greater for knees with moderate (4.0°) or severe (6.2°) valgus. Finally, lCV was greater than mCV in valgus knees compared to varus knees. CONCLUSION: The presence of lateral condyle hypoplasia in knees with genu valgum seems open to question. Apparent hypoplasia noted during the standard physical examination may be chiefly ascribable to distal valgus of the femoral epiphysis in the coronal plane and, with the knee flexed, to distal epiphyseal torsion, whose severity increases with the degree of valgus deformity. These considerations should be taken into account when performing distal femoral cuts for TKA, to ensure the restoration of normal anatomy in patients with genu valgus. LEVEL OF EVIDENCE: IV.

BACKGROUND: The objective of this study was to measure bone mineral density (BMD) of the cancellous bone in both femoral condyles and to compare the results according to the hip-knee-ankle (HKA) angle in patients with knee osteoarthritis. HYPOTHESIS: BMD of cancellous bone in the medial condyle is markedly lower in valgus knees compared to that in the lateral condyle in varus knees. METHODS: Consecutive patients with computed tomography (CT) of the knee and long-leg radiographs obtained in preparation for total knee arthroplasty were included. The 189 knees were divided into five groups based on whether the hip-knee-ankle angle was<170° (major varus deformity), 171°-177° (varus deformity), 178°-182° (normal alignment), 183°-189° (valgus deformity), and>190° (major valgus deformity). A protocol for CT measurement of BMD values at the femoral condyles was developed. Correlations between the HKA angle and BMD were assessed using the ratio of medial-to-lateral condyle BMD values (M/L). RESULTS: M/L was lower for knees with valgus deformity than for normally aligned knees (0.7 vs. 1, p<0.001). This difference was larger in the group with major valgus deformity, with a mean M/L value of 0.5 (p<0.001). M/L was higher for knees with major varus (mean, 1.2; p=0.035). The correlation coefficients showed excellent intra-observer and inter-observer agreement for the BMD measurements. CONCLUSION: The BMD values of the femoral condyles correlate with the HKA angle. BMD is lower at the medial femoral condyle of valgus knees, particularly when the deformity exceeds 10°. This finding may deserve consideration when planning total knee arthroplasty. LEVEL OF EVIDENCE: IV; retrospective study.

OBJECTIVES: Psychological consequences of grief among relatives are insufficiently known. We reported incidence of prolonged grief among relatives of deceased patients with cancer. METHODS: Prospective cohort study of 611 relatives of 531 patients with cancer hospitalized for more than 72 hours and who died in 26 palliative care units was conducted. The primary outcome was prolonged grief in relatives 6 months after patient death, measured with the Inventory Complicated Grief (ICG > 25, range 0-76, a higher score indicates more severe symptoms) score. Secondary outcomes in relatives 6 months after patient death were anxiety and depression symptoms based on Hospital Anxiety and Depression Scale (HADS) score (range 0 [best]-42 [worst]), higher scores indicate more severe symptoms, minimally important difference 2.5. Post-traumatic stress disorder symptoms were defined by an Impact Event Scale-Revised score >22 (range 0-88, a higher score indicates more severe symptoms). RESULTS: Among 611 included relatives, 608 (99.5%) completed the trial. At 6 months, significant ICG scores were reported by 32.7% relatives (199/608, 95% CI, 29.0-36.4). The median (interquartile range ICG score) was 20.0 (11.5-29.0). The incidence of HADS symptoms was 87.5% (95% CI, 84.8-90.2%) at Days 3-5 and 68.7% (95% CI, 65.0-72.4) 6 months after patient's death, with a median (interquartile range) difference of -4 (-10 to 0) between these 2 time points. Improvement in HADS anxiety and depression scores were reported by 62.5% (362/579) relatives. SIGNIFICANCE OF RESULTS: These findings support the importance of screening relatives having risk factors of developing prolonged grief in the palliative unit and 6 months after patient's death.
RESUMEN
PURPOSE: To conduct a network meta-analysis (NMA) comparing the results of randomized controlled trials (RCTs) among patients who underwent either isolated anterior cruciate ligament (ACL) reconstruction or combined lateral extra-articular tenodesis (LET) or anterolateral ligament reconstruction (ALLR). METHODS: RCTs that compared isolated ACL reconstruction and combined LET or ALLR were included with minimum 12 months follow-up. Studies that used the double-bundle technique were excluded. Outcome assessment included the number of positive pivot shifts, amount of anterior tibial translation, and International Knee Documentation Committee (IKDC) subjective, Tegner, and Lysholm scores. Bayesian NMA and the surface under the cumulative ranking area (SUCRA) were evaluated. RESULTS: A total of 1,077 patients from 11 RCTs were enrolled in this study. In NMA, the odds ratios (ORs) of positive pivot shift were significantly lower in ACL + ALLR (OR: 0.17; 95% CI: 0.027-0.67) than isolated ACL reconstruction, but no difference between ACL + ALLR and ACL + LET. There were no significant differences in anterior tibial translation among the techniques, but the IKDC subjective and Lysholm scores of ACL + ALLR and ACL + LET were significantly higher than isolated ACL reconstruction. ACL + ALLR were the most preferred in terms of residual pivot shift, anterior tibial translation, and IKDC subjective scores (SUCRA = 88.2%, 86.4%, and 93.1%, respectively). Additional lateral procedures resulted in significantly lower risk of graft failure (OR: 0.27; 95% CI: 0.1-0.71) than isolated ACL reconstruction. CONCLUSIONS: ACL + ALLR were found to have significantly better outcomes in terms of knee rotational stability and graft failure rate than isolated ACL reconstructions, but the clinical outcomes were uncertain after a minimum 12 months follow-up. Considering the greatest probability of obtaining better knee rotational stability in this NMA, ACL + ALLR was found to be the most preferred technique for patients with ACL injury. LEVEL OF EVIDENCE: Level II, network meta-analysis and systematic review of Level I and II studies.

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.

INTRODUCTION: The purpose of this study was to report the proportion and cause of unplanned revision surgery rates within 1 year following arthroscopic procedures. Our hypothesis was that there is a significant rate of unplanned returns (URs) occurring between 3 and 12 months after the initial procedure and that causes of revision are different when considering the delay after the index surgery. MATERIALS AND METHODS: Among 4142 consecutive patients who underwent an arthroscopic procedure in a single department of orthopedics and traumatology, patients undergoing revision surgery for any reasons directly related to the primary procedure were included. Cause for revision, surgical site, delay from index procedure, and number of revisions were screened. RESULTS: Seventy-eight patients underwent 97 revision surgeries (2.3%) for reasons directly related to the primary procedure. Most revision surgeries were performed after month 3 following index surgery (59 patients, 60.8%). Mean time to revision surgery was 5.3 ± 4.3 months (range 0-365 days). Usual early-onset (< 3 months) reasons for unplanned revision were surgical site infection (17 patients, 0.41%), wound-healing defect (12 patients, 0.29%), and hemorrhagic complication (7 patients, 0.17%). Reasons for delayed unplanned revision (> 3 months) were index procedure failure (21 patients, 0.51%), stiffness (18 patients, 0.43%), and removal of hardware (16 patients, 0.41%). CONCLUSIONS: Reasons for return to the operating room (OR) are different depending on the timepoint from index procedure. Patients should receive relevant information accordingly when scheduling any arthroscopic procedure, including up to 1-year potential complications.

PURPOSE: Meniscal injuries occurring during multi-ligament knee injuries (MLKI) are underreported. The purpose of this study was to compare the incidence and type of meniscal tears seen at the time of multi-ligament reconstruction surgery compared to those occurring during isolated anterior cruciate ligament (ACL) surgery. METHODS: Patients undergoing surgical treatment for MLKI and ACL-only injuries between 2010 and 2020 were reviewed. Two-hundred and thirty-five patients were included in the MLKI group. There were 131 chronic injuries and 104 acute injuries. Two-hundred and twenty-two ACL-only chronic injuries were used as a control group for comparison with the chronic MLKI group. Demographic data, type of meniscal tears, ligament injury patterns (Schenck classification) and time from injury to surgery were recorded. A delayed procedure was defined by a 4-week interval after the knee injury. RESULTS: A meniscus was torn in 69 knees (29.4%): 36 knees (15.3%) with an isolated medial meniscus tear, 33 knees (17.9%) with an isolated lateral meniscus tear,.Nine knees (3.8%) had both menisci torn. MLKI with medial or lateral-sided bicruciate ligament injuries (KDIIIM-KDIIIL) were significantly associated with a lower rate of meniscal tears than knee injuries involving the ACL-only and medial/lateral-sided ligament injuries (KDI) (medial-sided injuries p = 0.025; lateral-sided injuries p = 0.049). Lateral-sided injuries had significantly less meniscal damage than medial-sided injuries: 22/124 (17.7%) vs. 41/100 (41%); (p < 0.001). No significant differences were found for frequency, type and distribution of meniscal tears between acute and chronic MLKI surgery. ACL-only chronic injuries were associated with a higher rate of meniscal tears: 123/222 knees (55.4%) vs. 35/131 (26.9%) chronic MLKI; (p < 0.001), mainly involving the medial meniscus: 102/222 (46%) vs. 18/131 (13.7%); (p < 0.001). CONCLUSIONS: Meniscal tears were less common in the MLKI group than in the isolated ACL injury group. The degree of ligament injury patterns and the side of the injured collateral ligament influenced the type and incidence of meniscal damage. Contrary to isolated ACL injuries, a delayed procedure was not associated with a higher rate of meniscal lesions but did influence the type of treatment.

PURPOSE: The aim of this ESSKA consensus is to give recommendations based on evidence and expert opinion to improve diagnosis, preoperative planning, indication and surgical strategy in ACL revision. METHODS: The European expert surgeons and scientists were divided into four groups to participate in this consensus. A "literature group" (four surgeons); "steering group" (14 surgeons and scientists); "rating group" (19 surgeons) and finally "peer review group" (51 representatives of the ESSKA-affiliated national societies from 27 countries). The steering group prepared eighteen question-answer sets. The quality of the answers received grades of recommendation ranging from A (high-level scientific support), to B (scientific presumption), C (low level scientific support) or D (expert opinion). These question-answer sets were then evaluated by the rating group. All answers were scored from 1 to 9. The comments of the rating group were incorporated by the steering group and the consensus was submitted to the rating group a second time. Once a general consensus was reached between the steering and rating groups, the question-answer sets were submitted to the peer review group. A final combined meeting of all the members of the consensus was held to ratify the document. RESULTS: The literature review for the diagnosis and preoperative planning of ACL revision revealed a rather low scientific quality. None of the 18 questions was graded A and six received a grade B. The mean rating of all the questions by the rating group was 8.4 ± 0.3. The questions and recommendations are listed below. CONCLUSION: ACL revision surgery is a widely debated subject with many different opinions and techniques. The literature reveals a poor level of standardisation. Therefore, this international consensus project is of great importance. LEVEL OF EVIDENCE: II.
RESUMEN
BACKGROUND: Injuries to the posterolateral corner (PLC) of the knee are often overlooked but, require reconstruction in order to restore stability in varus and external rotation. Among the many anatomic and non-anatomic PLC reconstruction techniques available, the modified Larson (mLR), LaPrade (LPR) and Versailles reconstruction (VR) procedures are widely used. HYPOTHESIS: The hypothesis was that anatomic PLC reconstruction (VR and LPR procedures) provides better restoration and control of external rotation. PATIENTS AND METHODS: Fifteen fresh-frozen cadaveric knees were tested to compare the 3 procedures. Varus laxity on stress radiographs in full knee extension and external rotatory laxity on dial test at 30° flexion were quantified at 3 phases: intact knee, PLC sectioned and PLC reconstructed. RESULTS: Mean varus laxity did not differ significantly between techniques in intact knees (p=.14), after PLC sectioning (p=.14) or after PLC reconstruction (p=.17). After PLC reconstruction, varus laxity was restored, with no statistical difference between mLR, VR and LPR compared to intact test values (respectively, -1.0, -1.3 and -1.5; p=.98). In all 3 groups, mean external rotation laxity on dial test at 30° flexion did not significantly differ between intact knees (p=.32) and after PLC sectioning (p=.15). After PLC reconstruction, the mLR technique was significantly less effective in restoring rotational stability than the VR and LPR techniques (p=.025). DISCUSSION: The VR technique provided similar outcomes to LPR for restoring stability in varus and external rotation. The 2 "anatomic" reconstruction procedures (VR and LPR) were significantly more effective than the modified Larson technique for external rotation control, confirming the study hypothesis. Consequently, it remains preferable to use anatomic techniques in multiligament injuries involving the PLC. LEVEL OF EVIDENCE: IV, cadaver study.

SFA Datalake is the registry platform of the French Society of Arthroscopy (SFA). It was designed to collect and store data on arthroscopic orthopedic surgery and joint-sparing surgery in French-speaking countries. The anterior cruciate ligament (ACL) tear registry is the first registry to be set up based on SFA Datalake. Registries are intended to enable systematic standardized data collection, and provide information for surgeons to improve clinical practice and results. The ACL tear registry was designed in the light of guidelines, the literature and existing registries. Data are collected prospectively on a secure on-line application accessible via a computer or smartphone. Data collection is organized according to clinical examination results, preoperative findings, and follow-up data based on patient-administered subjective quality of life questionnaires. The pilot committee consists of 5 SFA board members, appointed for 2 years. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction is a frequent procedure, with room for improvement by rehabilitation measures and associated peripheral and meniscal surgeries that are currently under assessment, requiring follow-up. Outside France, there have been ACL registries for 20 years now. The French Arthroscopy Society (SFA) decided to set up an ACL tear registry within its SFA DataLake registry platform. MATERIAL AND METHOD: This article presents the methodology underlying the ACL Tear Registry: i.e., identification, definition and coding of essential and relevant data. A test phase comprised an initial assessment to improve data quality and overall coherence, to optimize data-entry time for patients and practitioners, who are the guarantors of the registry's use and efficacy. RESULTS: The SFA DataLake ACL Tear Registry was made available to SFA members in December 2021. It aims to enable a review of practices for surgeons, early detection of failure of procedures and implants, with rates of failure and abnormal complications, and identification of prognostic factors for outcome, especially regarding original items that do not figure in previous registries. CONCLUSION: SFA DataLake strikes a balance between "indispensable" and "original" items. The choice of contents and data quality is founded on a robust methodology with overall coherence, enabling analysis of large cohorts and comparisons with the literature and other registries. However, it remains to assess rates of data entry and item relevance as the Registry progresses. LEVEL OF EVIDENCE: IV.
