RESUMO
Acetabular dysplasia is a hip condition characterized by abnormal development of the acetabulum, which can be present from birth or develop during childhood and may persist into adulthood. Mild or borderline acetabular dysplasia frequently is associated with cam-type femoroacetabular impingement in adults. Over time, the association of impingement and abnormal contact can lead to hip pain, cartilage damage, labral tears, and an increased risk of developing hip osteoarthritis. Several surgical treatments have been proposed: arthroscopic capsular plication, periacetabular osteotomy, or shelf acetabuloplasty. As mini-invasive shelf acetabuloplasty procedure has already proven its effectiveness, an arthroscopic shelf acetabuloplasty represents a less-invasive, less-risky procedure and allows during the same procedure to perform intra-articular resection of the femoral cam, labrum repair and capsular plication. This Technical Note describes an original technique of arthroscopic shelf acetabuloplasty that combines an outside-in arthroscopic approach for the intra-articular procedure (labral repair, femoroplasty, capsular plication) and an endoscopic shelf acetabulopasty with a tricortical iliac crest autograft secure with a single cannulated screw.
RESUMO
PURPOSE: The objective of this study was to evaluate the functional outcome during follow-up (FU) after endoscopic tenotomy for iliopsoas (IP)-cup impingement and to quantitatively analyze the hip flexion strength. METHODS: This was a monocentric, retrospective cohort study of a single surgeon series. Functional assessment was based on the modified Harris score, the Oxford score and the visual analog scale score. Strength was measured with a handheld dynamometer in the sitting and lying position. RESULTS: Thirty-six IP tenotomies for cup impingement were performed between May 2013 and November 2021. Seven (19%) patients were lost to FU. At the time of tenotomy, the mean (standard deviation) age was 62,6 (12,2) and BMI was 26,5 (4,1). The mean FU time after tenotomy to the last FU was 3,6 (0,8) years. All three outcome scores improved from preoperatively to six months postoperatively (p < 0.001). There were no significant change from six months to last FU. The minimal clinically important difference (MCID) of the modified Harris score was set at 25. 20 (69%) patients had values that exceeded the threshold at one month and six months and neutral 19 (65.5%) had values that exceeded the threshold at the last FU. The limp symmetry index concerning hip flexion strength was 63% at 90° and 40% at 30° at the last FU. CONCLUSION: Most patients significantly improved their outcome scores after endoscopic iliopsoas tenotomy, with results remaining consistently stable over time. Despite a significant loss in hip flexion strength, the majority of patients did not report any impairment of their quality of life. STUDY DESIGN: Level III, Retrospective cohort study.

PURPOSE: This multicenter study aimed to determine the incidence of lateral meniscus posterior root tears (LMPRTs) in patients undergoing ACL reconstruction and identify associated risk factors. METHODS: We conducted a retrospective, multicenter study using data from the Francophone Arthroscopic Society's registry. The study included all the patients in the registry who underwent ACL reconstruction surgery between June 2020 and June 2023, we excluded incomplete data. We compared delay from injury to surgery between LMPRTs group and No LMPRTs group. Variables investigated as potential risk factors for LMPRTs included age, sex, nature of surgery (primary or revision), pivot shift test result, side-to-side laxity under anesthesia, presence of ACL remnant, occurrence of medial meniscal tear, and presence of collateral ligament injury. Risk factors were analyzed using a logistic regression model. RESULTS: Among the 5359 patients analyzed, LMPRTs occurred in 7.0% (n=375) of cases during ACL reconstruction. Mean age at surgery was 29.3 +/- 10.3 years old [11-77]. Concerning delay to surgery, the mean time was 8.4 +/- 23.1 weeks [0.0-347.2] in the No LMPRTs group and 6.5 +/- 10.2 weeks [0.2-61.6] in the LMPRTs group (p = 0.109). Univariate analysis revealed that male sex (p < 0.001), revision surgery (p < 0.001), medial meniscal injury (p = 0.007), ACL remnant (0% vs > 70%, <10% vs > 70%, 10 to 30% vs > 70%, 30 to 50% vs > 70%, 50 to 70% vs > 70%; p < 0.001) and higher pivot shift grade (p = 0.011) were significantly associated with a presence of LMPRTs. Age, side-to-side laxity, and collateral ligament injury were not found to be significant risk factor In multivariate analysis : male sex, revision surgery, pivot shift test result and a low volume of ACL remnant remained significant. Side to side laxity was also a significant factor in multivariate analysis. CONCLUSION: This study identified male sex, revision surgery, low volume of ACL remnant, side to side laxity and higher grade of pivot shift as significant risk factors for LMPRTs during ACL reconstruction.
RESUMO
PURPOSE: The study aimed to estimate the prevalence of ramp lesions among patients undergoing anterior cruciate ligament (ACL) reconstruction and identify risk factors associated with these lesions. METHODS: A retrospective, multicentre cohort study was conducted using data from the Francophone Arthroscopic Society's registry, including 5359 patients who underwent ACL reconstruction (ACLR) from June 2020 to June 2023. Potential risk factors for ramp lesion such as patient demographics, revision surgery, pivot shift, side-to-side anteroposterior laxity, medial collateral ligament (MCL) injury, lateral meniscal tear and the volume of ligament remnant were evaluated using multivariate regression analyses. BMI and delay to surgery were also assessed. RESULTS: Ramp lesions were identified in 822 patients (15.3%). Univariate analysis identified male sex, younger age, revision surgery, lateral meniscal injury, percentage of ACL remnant (all p < 0.0001) and pivot shift (p = 0.0103) as significant risk factors. MCL injury was associated with a lower risk (p < 0.0001). In multivariate analysis, male sex, younger age, revision surgery, lateral meniscal injury and percentage of ACL remnants remained significant risk factors, while MCL injury remained a protective factor. The anteroposterior laxity wasn't a significant predictor in either analysis. In subgroup analysis, there were no differences concerning body mass index (n.s) and the delay to surgery (n.s). CONCLUSION: The study identified male sex, younger age, revision surgery, lateral meniscal injury and pourcentage of ACL remnant as significant risk factors for ramp lesions, with MCL injury acting as a protective factor. This will help regarding the suspicion and identification of ramp lesions. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: In younger patients, meniscal repair is recommended for isolated lateral meniscus tears that are most often due to acute trauma. But there is little published data on the outcomes of repairing this specific type of lesion. The goal of this study was to evaluate the clinical outcomes, report the failure rate of repairing radial tears of the lateral meniscus in stable knees and determine the risk factors for failure. MATERIALS AND METHODS: All patients who had a stable knee and underwent arthroscopic repair of a radial lateral meniscus tear between April 2013 and December 2019 were reviewed retrospectively. Failure was defined as revision surgery for recurrence of symptoms (pain, locking) with intraoperative confirmation that the meniscus did not heal. The following data were collected: demographics (age, sex, BMI), time to surgery, clinical outcome scores (Tegner, Lysholm, IKDC), surgical details (repair technique, lesion zone, number of sutures). RESULTS: Thirty patients were included having a mean age of 20.1years (14-31). The follow-up ranged from 24 to 110months (mean 66.8±25.2). An all-inside repair was done in 6 patients (20%); an outside-in technique was done in 17 patients (57%) and a combination of all-inside and outside-in was done in 7 patients (23%). Four patients (13%) had a recurrence of their symptoms later on, while participating in sports. All the recurrences were at the initial tear site. The time to revision surgery was 16, 19, 24 and 37months in these four patients (mean 24±9). All the other patients were able to resume sports at their pre-injury level. Significant improvement in the IKDC, Lysholm and Tegner functional scores were found between the preoperative and postoperative assessments. No statistically significant risk factors for failure were identified. DISCUSSION: The functional healing rate after repair of a radial lateral meniscus tear in a stable knee was 86% at a mean follow-up of 5years, with the surgical technique having no impact on the long-term result. Most of the failures occurred within 2years of the repair procedure. We recommend repairing these tears as they have considerable healing potential. LEVEL OF EVIDENCE: IV; retrospective observational cohort study.

BACKGROUND: There is ongoing debate about the best way to manage ramp lesions at the time of anterior cruciate ligament (ACL) reconstruction (ACLR). Type 3 lesions are not visible by the transnotch approach without superior debridement, making the management debate even more problematic. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the rate of secondary surgical interventions according to the management method of a type 3 ramp lesion concomitant with primary ACLR. The hypothesis was that the rate of secondary ACL or meniscal interventions would be higher in patients who underwent all-inside repair. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective analysis of all patients who underwent primary ACLR with a type 3 ramp lesion between January 2012 and May 2020, regardless of the treatment method, was performed. The main criterion analyzed in this cohort was a secondary surgical intervention, defined as revision ACLR or a reintervention of the repaired meniscus. A survivorship analysis was performed to evaluate secondary surgical interventions in 3 groups: all-inside repair, suture hook repair, and left in situ. The following data were collected preoperatively and at the last follow-up: patient characteristics, time to surgery, side-to-side difference in laxity, pivot shift, Lysholm score, subjective International Knee Documentation Committee score, Knee injury and Osteoarthritis Outcome Score, Tegner score, and meniscal repair failure rate. RESULTS: A total of 113 patients who underwent type 3 ramp lesion repair concomitant with ACLR were included: 52 (46.0%) in the all-inside repair group, 23 (20.4%) in the suture hook repair group, and 38 (33.6%) in the lesion left in situ group. There were 17 patients (15.0%) who underwent a secondary intervention because of ACL graft failure (n = 6) or meniscal repair failure (n = 15 [4 of whom underwent a concomitant ACL reintervention]). Overall, 62 patients (54.9%) underwent combined ACLR and anterolateral ligament reconstruction, while 51 patients (45.1%) underwent isolated ACLR. In the adjusted Cox model, the type of meniscal repair was not statistically significantly associated with secondary surgical interventions. The only risk factor for secondary surgical interventions in this cohort was isolated ACLR (hazard ratio, 8.077; P = .007). CONCLUSION: The rates of secondary surgical interventions after medial meniscal type 3 ramp lesion repair concomitant with ACLR were similar regardless of the management method of the meniscal lesion. Despite not being associated with meniscal treatment, this rate was 8 times higher for patients who underwent isolated ACLR in this cohort; this is probably because of the protection that lateral extra-articular procedures provide to the ACL graft.

Purpose: To compare the accuracy of patient-specific guides (PSCG) to the standard technique in medial open-wedge high tibial osteotomy (OWHTO). Secondary objectives were to evaluate factors that could influence accuracy and to compare the complication rate and operating time for both procedures. Methods: A retrospective analysis of prospective collected data was performed. Between March 2011 and May 2018, 49 patients with isolated medial knee osteoarthritis who were operated for OWHTO using PSCG and 38 patients using the standard technique were included. Preoperative and postoperative deformities were evaluated on long leg radiographs by measuring the mechanical medial proximal tibial angle, mechanical lateral distal femoral angle, hip knee ankle angle (HKA), and joint line convergence angle. Pre- and postoperative posterior tibial slope was also evaluated. Accuracy was evaluated by analysing the difference between the preoperative planned and the actual postoperative HKA. Operating time and complication rate were also recorded in both groups. Results: The mean preoperative HKA was 173.4° (±3.1°) in the PSCG group and 173.3° (±2.4°) in the standard group (p = 0.8416). Mean planned HKA were 182.8° (±1.1°) and 184.0° (±0°) respectively for the PSCG and the standard group. Mean postoperative HKA were 181.9° (±1.9°) and 182.6° (±3.1°) respectively for the PSCG and the standard group. An accuracy of ±2° in the HKA was achieved in 44 (90%) in the PSCG group and 24 (65%) in the standard group (p = 0.006). The probability of achieving a HKA accuracy was four times higher for patients in the PSCG group (odds ratio [OR] = 4.06, [1.1; 15.3], p = 0.038). Also, higher preoperative Ahlback grade was associated with precision, all other parameters being equal (OR = 4.2, [0.13; 0.97], p = 0.04). Conclusion: In this study, the PSCG technique was significantly more accurate for achieving the planned HKA in OWHTO. Complication rates and operating times were comparable between groups. Level of Evidence: Level IV, case-control study.
RESUMO
BACKGROUND: Arthrogenic muscle inhibition (AMI) is a process in which neural inhibition after injury or surgery to the knee results in quadriceps activation failure and knee extension deficit. PURPOSE: To determine the incidence and spectrum of the severity of AMI after acute anterior cruciate ligament (ACL) injury using the Sonnery-Cottet classification, to determine the interobserver reliability of the classification system, and to investigate potential important factors associated with AMI after ACL injury. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Consecutive patients who had an acute ACL injury between October 2021 and February 2022 were considered for study inclusion. Eligible patients underwent a standardized physical examination at their first outpatient appointment. This included an assessment of quadriceps inhibition, identification of any extension deficits, and grading of AMI and its reversibility according to the Sonnery-Cottet classification. RESULTS: A total of 300 consecutive patients with acute ACL ruptures were prospectively enrolled in the study. Of them, 170 patients (56.7%) had AMI. Patients evaluated with AMI showed a significantly inferior Lysholm score, International Knee Documentation Committee score, Simple Knee Value, and Knee injury and Osteoarthritis Outcome Score than patients without AMI (P < .0001). Multivariate analysis revealed that the presence of effusion, concomitant injuries, and high pain scores were associated with a significantly greater risk of AMI. Additional associations with the presence of AMI included a short duration between injury and evaluation, the use of crutches, and using a pillow as a support at night. In contrast, a previous ACL injury was associated with significantly lower odds of developing AMI (OR, 0.025; 95% CI, 0-0.2; P = .014). Among the 170 patients with AMI, 135 patients (79%) showed a resolution of their inhibition at the end of the consultation after application of simple exercises; the remaining 35 patients required specific rehabilitation. Interobserver reliability of the classification system was almost perfect (95% CI, 0.86-0.99). CONCLUSION: AMI occurs in over half of patients with acute ACL injuries. When it occurs, it is easily reversible in the majority of patients with simple exercises targeted at abolishing AMI. The presence of "red flags" should increase the index of suspicion for the presence of AMI, and these include the presence of an effusion, high pain scores, a short time between injury and evaluation, multiligament injuries, the use of crutches, and using a pillow as a support at night. Patients with a history of ipsilateral or contralateral ACL injury are at a significantly lower risk of AMI than those with a first-time ACL injury.

PURPOSE: To assess the functional and clinical outcomes of patients who underwent either open or endoscopic Whiteside transfer of gluteus maximus and tensor fascia lata muscles in cases of massive rupture of gluteus medius tendon associated with muscle atrophy on a native hip METHODS: This retrospective, descriptive, single-centre study was conducted by a single operator with a minimum follow-up period of 12 months. All Whiteside palliative transfers performed on patients with Type 5 gluteus medius tendon rupture, according to Lall's classification, resulting in painful and treatment-resistant Trendeleburg gait between 2017 and 2022 were included. Functional evaluation was based on modified Harris Hip Scores (mHHS), iHOT-12, Non-Arthritic Hip Score (NAHS), and the pain on a Visual Analog Scale (VAS). Muscle strength was clinically assessed using the MRC classification. RESULTS: Between January 2017 and January 2022, a total of 15 Whiteside palliative transfers were identified, including nine (60%) open procedures and 6 (40%) endoscopic procedures, performed on 13 patients. One patient was excluded, and none were lost to follow-up. The median follow-up period was 41 (12; 59) months. The median age at the time of surgery was 74 (66; 76) years. The male-to-female sex ratio was 0.27. Functional results demonstrated a significant improvement in all scores: NAHS (45 vs. 72, p = 0.002), mHHS (22 vs. 55, p = 0.002), iHOT-12 (101 vs. 56, p = 0.002), and VAS (8 vs. 3, p = 0.002). Clinical outcomes also showed improvements in muscle strength (p = 0.003), single-leg stance (p = 0.01), and gait (p = 0.02). No significant differences were found in the various scores between the endoscopic and open techniques. CONCLUSION: Whiteside transfer surgery, whether performed through open surgery or endoscopically, is a palliative surgical approach that should be considered for patients with irreparable gluteus medius tendon tears, where the main symptom is trochanteric pain. This procedure yields satisfactory clinical and functional outcomes, although the gains in abduction strength recovery and gait improvement are modest.

BACKGROUND: It is nowadays recommended to "Save the meniscus". This paradigm is based on the affirmation that an extended meniscectomy exposes to the risk of long-term secondary osteoarthritis and the global failure rate of a longitudinal tear repair remains low, whether it is the medial or lateral meniscus, with or without anterior cruciate ligament (ACL) reconstruction. However, each kind of lesion has to be studied separate. PURPOSE: The study aimed to focus on a homogeneous population of isolated repair of the bucket handle tear (BHT) of the medial meniscus (MM) in patients with stable knees to evaluate failure rate at a minimum of three years of follow-up. The secondary objectives were to evaluate any risk factors or protective factors of failure, clinical outcomes, and secondary amount of meniscectomy in failure cases compared to the amount of meniscus fixed in the first surgery. METHODS: All patients who underwent arthroscopic repair of a BHT of the MM situated in the red-on-red or red-on white (RW) zone on a stable knee between January 2010 and December 2018 were evaluated retrospectively. Failure was defined as a need for reoperation for recurrence of meniscal symptoms (pain, locking) on the medial side with per-operative confirmation of the absence of healing. The following parameters were studied: demographics (age, gender, BMI), time from injury to surgery, clinical scores (Tegner, Lysholm, International Knee Documentation Committee [IKDC]), surgical findings (extent and zone of the tear), surgical management (number and type of suture). RESULTS: Thirty-nine patients were included. The mean follow-up was 77.2±24.4 [36-141] months. Twenty-seven (69%) failures were recorded. In 56% (15/27) of the reoperations, the meniscectomy amount was smaller than what it would have been done in the first surgery. All clinical scores improved significantly from pre- to post-operatively; all patients met minimal clinically important differences for all the scores. No risk factors were found significant in the multivariate analysis. CONCLUSION: Repairing an isolated BHT of the MM is associated with a high failure rate. Despite the failure, we observed that the meniscectomy area was smaller than documented in the primary surgery in most of the cases and repair must still be considered as the first option. LEVEL OF EVIDENCE: IV; retrospective cohort series.
RESUMO
INTRODUCTION: With the recent interest in hip-spine relationship, the link between femoroacetabular impingement (FAI) and the lumbar-pelvic-femoral complex (LPFC) appears decisive. The objectives of this study were (1) to compare the pelvic version, as well as (2) all the parameters of the LPFC between two populations of healthy subjects, comparing those with radiological signs of FAI to those without and finally, (3) to evaluate the LPFC parameters according to the type of FAI. HYPOTHESIS: Asymptomatic subjects with radiological signs of FAI had superior pelvic anteversion. MATERIALS AND METHOD: This retrospective study was based on a prospective cohort of 118 voluntary asymptomatic patients including 62 men (52.5%) with a mean age of 25.6 years±4.4 (19-39). The following parameters: pelvic version (PV), pelvic incidence (PI), lumbar lordosis (LL), sacral slope (SS), hip flexion, intrinsic (IER) and extrinsic (EER) extension reserve were measured using EOS imaging™ in the reference standing position and the lunge position. The radiological signs of FAI (cam, pincer, mixed) were identified on these acquisitions then separated into 2 groups. The first was the group presenting with one or more images of FAI (FAI+) and the second group with no images of FAI (FAI-). RESULTS: There were 143 hips in the FAI+ group compared to 93 hips in the FAI- group. There were 36.4% cams and 45% pincers. With an average of 9.08°±7.81 (-11.0; 27.0) versus 12.33°±8.94 (-5.0; 55.0), the PV was significantly lower (p=0.022) in the FAI+ group compared to the FAI- group. A post-hoc power analysis on the primary outcome (PV) confirmed sufficient power (1-ß=0.809). Compared to the FAI- group, the cam group presented a significantly lower IER and EER (respectively p=0.014 and p=0.047). The comparative analysis between the FAI- and pincer groups found a significant difference in PI (p=0.001), PV (p<0.001), IER (p=0.017) and hip flexion (p<0.001), SS in lunge position (p=0.031) and EER (p=0.039). CONCLUSION: Asymptomatic subjects with radiographic signs of FAI present with weak pelvic version when standing. This pelvic hyper-anteversion is mainly found in the event of a radiological pincer sign. LEVEL OF EVIDENCE: III, retrospective comparative study.

INTRODUCTION: The occurrence of iliopsoas impingement (IPI) after total hip arthroplasty (THA) is a proven risk factor for negative outcomes. Endoscopic or arthroscopic tenotomies of the iliopsoas offer a surgical solution with short-term results that have already been validated in prospective multicenter series. We carried out a review of the patients at more than 5 years of follow-up in order to assess the stability of the results over time. HYPOTHESIS: Our main hypothesis was that endoscopic/arthroscopic tenotomies allow stable medium-term resolution of the painful symptoms of IPI. Our secondary hypothesis was that medium-term survival was satisfactory. MATERIAL AND METHOD: This study is a continuation of a multicenter prospective series. Patients were contacted through multiple channels in order to: obtain an Oxford score, assess for satisfaction, psoas irritation, and daily pain on a visual analogue scale (VAS). RESULTS: Of 64 patients in the original study, 57 were contacted. The Oxford score at the last follow-up was 40.7±7.7 [12-48]. There was a significant difference between the Oxford scores preoperatively, at 8 months and at the last follow-up. The mean satisfaction out of 10 was 8.0±2.1 [1-10]. We found 84% satisfaction at 5 years against 83% at 8 months. The VAS was 2.1±2.3 [0-10]. A straight leg psoas sign was present in 19.6% (10/51) of patients at 5 years, compared to 15.6% (8/51) at 8 months. The sign disappeared in four cases, while it reappeared during the interval in six cases. Survival was 91.2% (95% CI: 80.2-96.3) at 5 years. CONCLUSION: Endoscopic/arthroscopic iliopsoas tenotomies represent a permanent medium-term solution to treat IPI after THA. The existence of a force differential or an acetabular overhang does not seem, within a certain limit, to impact the results in the medium term. LEVEL OF EVIDENCE: IV; prospective series without control group.

INTRODUCTION: The radiological study of the sagittal alignment of the spine in static and dynamic positions has allowed a better understanding of the clinical results of total hip prostheses. According to the Roussouly classification, the sacral slope in a standing position characterizes the patient with a stiff spine (less than 35Ì) or a flexible spine (greater than 35Ì). The objectives of this study were to compare, in a population of patients operated on for femoroacetabular impingement (FAI), firstly, the kinematics of the lumbar-pelvic-femoral complex and secondly, the clinical presentation depending on whether the spine is stiff or flexible. HYPOTHESIS: Patients with stiff spines (SS<35Ì) were "hip users" and had less ability to compensate for their hip pathology. MATERIAL AND METHOD: This prospective and comparative multicenter study was conducted with patients operated on arthroscopically for FAI between 2020 and 2021. All patients included received preoperative EOS imaging of the lower limbs and spine, in standing and seated positions. The following parameters were measured: pelvic tilt (PT), pelvic incidence (PI), lumbar lordosis (LL), and sacral slope (SS), as well as dynamic parameters (intrinsic mobility of the hip: delta standing/sitting femoral sacral angle, and of the pelvis: delta standing/sitting sacral slope). The functional result was evaluated at 1 year. RESULTS: In the stiff spine group, 62 patients were included versus 138 in the flexible spine group. The mean follow-up was 15.1±3.3 months (9.2-24.3). Nineteen patients were lost to follow-up and there were 2 revisions for iterative arthroscopy. Intrinsic pelvic mobility and intrinsic hip mobility were 16̱13.5 (-12; 44) and 44.5̱28.5 (-9; 99) respectively in the stiff spine group. In the flexible spine group, these same measurements were 22̱11.5 (-30; 45) and 29.7̱22.7 (-33; 82) respectively. In the stiff spine group, the symptoms occurred at a significantly younger age: 28.3 years±9.5 (18-51) versus 31 years±8 (18-54) (p=0.017). DISCUSSION: The sacral slope is a determining factor in the kinematics of impingement and the appearance of symptoms. The sacral slope helps define the concept of a "hip user" in symptomatic FAI. LEVEL OF EVIDENCE: IV.

BACKGROUND: Anterior cruciate ligament (ACL) repair (ACL-Rp) is known to be a valuable alternative to ACL reconstruction (ACL-Rc) in selected indications. The majority of the ACL-Rp techniques recommend the use of a synthetic brace. The use of the gracilis allows both a biological internal brace and anterolateral ligament reconstruction (ALR). PURPOSE: The primary objective was to compare the early ability to return to sports between patients who underwent ACL-Rp using a gracilis autograft as an internal brace augmentation with ALR and patients who underwent the conventional ACL-Rc with ALR technique sacrificing both the gracilis and the semitendinosus. The secondary objective was to compare the failure rate, clinical scores, and return to sports at a minimum follow-up of 2 years. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective analysis was undertaken. A total of 49 patients who underwent ACL-Rp with ALR between December 2018 and May 2019 were propensity matched at a 1:1 ratio to those who underwent ACL-Rc with ALR during the same period. The decision to perform ACL-Rp with ALR was based on preoperative selection and intraoperative arthroscopic findings: proximal avulsion tear, partial ACL tear, low- to midlevel sports participation, and good tissue quality. The ability to return to sports was assessed using isokinetic tests and the Knee Santy Athletic Return to Sport test functional test at 6 months postoperatively. At the final follow-up, knee laxity parameters, return to sports, and clinical outcome (Lysholm score, Tegner Activity Scale score, International Knee Documentation Committee score, Knee injury and Osteoarthritis Outcome Score, and Anterior Cruciate Ligament-Return to Sport after Injury score) were recorded. RESULTS: The ACL-Rp group had significantly less hamstring strength deficit when compared with their counterparts who underwent ACL-Rc (0.2% vs 10.2% in concentric, P < .001; 2.5% vs 14% in eccentric, P < .001). The mean Knee Santy Athletic Return to Sport test score was significantly higher in the ACL-Rc group (69.7% ± 16.6% [range, 19%-100%] vs 61% ± 16.8% [range, 19%-100%]; P = .001). In the ACL-Rp group, 61% (30/49) of the patients were authorized to return to pivot sports versus 41% (20/49) in the ACL-Rc group (P = .04). At a mean final follow-up of 31.4 ± 3.5 months, no significant differences were demonstrated between groups with respect to clinical scores and knee laxity parameters. There was a trend for a higher failure rate in the ACL-Rp group without any significance (ACL-Rp: 6.1% [3/49] vs ACL-Rc: 0%; P = .08). CONCLUSION: At 6 months after operation, harvesting only the gracilis with this ACL-Rp and augmentation with ALR technique was linked to a better early ability to return to sports compared with the ACL-Rc with ALR technique harvesting both the gracilis and semitendinosus. This technique had a limited effect on early flexion strength and provided a satisfactory rerupture rate.

PURPOSE: To investigate the minimum use that correlates with the best outcomes in term of complications associated with self-directed rehabilitation mobile application and to explore the user profile and usage habits. METHODS: This was a single-center retrospective study of 356 patients who underwent ACL reconstruction surgery between November 2019 and August 2020. Complications were defined as the presence of an extension deficit ≥ 5° after 6 weeks and/or the presence of cyclops syndrome. The demographics, sports competition level and number of connections were collected by the application. RESULTS: The complication rate was reduced 4.2-fold with at least 2 weeks of use (2.4% (3/123) (with 0.8% (1/123) of cyclops syndrome) versus 10.8% (23/212) (with 3.3% (7/212) cyclops syndrome), p = .04). The mean duration of use was 20 ± 23 days with a frequency of 2.1 ± 2.3 connections per day. The usage rate was 50% in week 1, 35% in week 2, and 24% in week 3. There was one peak in the abandon rate during the first few days of use and a second peak at Day 10 when physiotherapy sessions started. There were two dips in the abandon rate associated with the follow-up visits at Days 21 and 45. Greater use was found in older patients (p = .0001) and female patients (p = .04). CONCLUSIONS: When using the application for a minimum of 2 weeks, the risk of complications was reduced 4.2-fold. The typical users of a self-directed rehabilitation application after ACL surgery in this study were women and patients over 30 years of age. LEVEL OF EVIDENCE: IV, retrospective.
RESUMO
BACKGROUND: Failure rates of repaired bucket-handle medial meniscal tears (BHMMTs) concomitant with anterior cruciate ligament reconstruction (ACLR) are as high as 20%. The outcomes of posteromedial portal suture hook repair have not been compared with all-inside repair techniques for this subtype of meniscal lesion. PURPOSE/HYPOTHESIS: The aim of this study was to evaluate the outcomes and failure rates of patients who underwent BHMMT repair concomitant with ACLR using an all-inside technique, suture hook + all-inside technique, or suture hook + outside-in technique. It was hypothesized that no significant differences in failure rates would be found between the groups. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective analysis was performed on patients diagnosed with a BHMMT who underwent meniscal repair during primary ACLR and had a minimum follow-up of 2 years. Patients were grouped based on the meniscal repair technique used: all-inside repair, suture hook + all-inside repair, or suture hook + outside-in repair. At the end of the study period, secondary medial meniscectomy rates were determined. RESULTS: The study population comprised 253 patients who underwent repair of a BHMMT with concomitant ACLR with a mean follow-up of 94.0 ± 47.6 months. A total of 114 patients (45.1%) underwent all-inside repair, 61 patients (24.1%) underwent suture hook + all-inside repair, and 78 patients (30.8%) underwent suture hook + outside-in repair. Overall, there were 36 failures. The failure rates were 20.2%, 14.8%, and 5.1%, respectively (P = .0135). All-inside repairs were >4 times more likely to fail than suture hook + outside-in repairs (hazard ratio [HR], 4.103; 95% CI, 1.369-12.296; P = .0117). Failure was also 3 times higher (HR, 2.943; 95% CI, 1.224-7.075; P = .0159) for patients <30 years of age compared with those aged ≥30 years. An additional anterolateral ligament reconstruction (ALLR) was also found to reduce the failure rate of repaired BHMMTs concomitant with ACLR. CONCLUSION: Combined suture hook + outside-in repair of BHMMTs resulted in significantly fewer failures than all other techniques. Furthermore, age <30 years and no additional ALLR were associated with higher failure rates.

INTRODUCTION: The role of arthroscopic treatment of femoroacetabular impingement (FAI) in mild or borderline hip dysplasia (lateral center edge angle=18-25) is controversial. It is recommended to combine capsular plication with femoral neck osteoplasty and suture repair of the labrum. Few studies have investigated which radiological parameters are associated with failure of this procedure. HYPOTHESIS: A larger number of radiological signs of mild or borderline hip dysplasia than radiological signs of FAI negatively influence the outcomes of arthroscopic treatment. METHODS: This was a retrospective study done with data collected prospectively after a minimum of 2 years' follow-up in patients who underwent arthroscopic treatment of FAI due to cam impingement combined with mild to moderate hip dysplasia. Patients with hip osteoarthritis graded as ≥ Tönnis 2 were excluded. Functional outcome scores (mHHS and NAHS) were determined along with the need for reoperation. Three groups were defined based on the outcomes: success (mHHS ≥ Patient Acceptable Symptomatic State [PASS]); moderate improvement (improvement in mHHS + mHHSAssuntos

RESUMO
PURPOSE: The aim of this study was to review the outcomes of lateral meniscus posterior root tears repair at the time of ACL reconstruction at a minimum 2-year follow-up. METHODS: Between March 2015 and August 2018, 2017 patients underwent primary ACL reconstruction and were considered for study eligibility. Lateral meniscus posterior root tears were identified arthroscopically, and repair was performed with a transtibial pull-out suture technique or a side-to-side suture technique. Clinical outcomes were recorded at the time of physical examination. At the end of the study period, patients were contacted to determine whether they had required reoperation. RESULTS: Lateral meniscus posterior root tears were identified in 153 out of the 2,017 primary ACL reconstructions (7.6%). Ninety-nine patients were included for analysis: 23 transtibial pull-out sutures and 76 side-to-side repairs. At a mean follow-up of 42 ± 10 months, one patient (1%) had undergone reoperation for failure of the side-to-side repair. There were 11 reoperations in 10 patients (10.1%), including 6 cyclops syndrome, 1 graft rupture, 1 tibial bone cyst, 1 medial and 1 lateral meniscus repair failure, and 1 arthrolysis. Postoperatively, ninety (90.9%) patients were graded A for the IKDC objective score and 9 (9.1%) patients were graded B, with an IKDC subjective score of 86.9 ± 7.6, a Lysholm score of 90.7 ± 6.7 and a median Tegner Activity Scale of 6 (3-9). All of their objective and subjective evaluations improved after surgery (p < 0.001) except for the Tegner Activity Scale. Ten patients underwent second look arthroscopy (10.1%), lateral meniscus healing was observed in 9 out of 10 patients (90%). CONCLUSION: This study demonstrated that lateral meniscus posterior root tear repair is a safe procedure with a very low reoperation rate at a minimum follow-up of 2 years. LEVEL OF EVIDENCE: IV.

BACKGROUND: Rehabilitation after surgery is a crucial process that governs the final functional outcome. The self-rehabilitation smartphone application Doct'up (Healing SAS, Lyon, France) is designed for patients who have had anterior cruciate ligament (ACL) reconstruction surgery. In France in the spring of 2020, the lockdown mandated due to the COVID-19 pandemic prevented patients from seeing their physiotherapists for 2 months. The objective of this study was to compare the clinical outcomes in two groups of patients who underwent ACL reconstruction surgery: in one group, surgery performed before the lockdown was followed by standard in-person physiotherapy while, in the other, surgery was done just before the lockdown and rehabilitation was performed by the patients themselves using the phone application. HYPOTHESIS: Using a self-rehabilitation smartphone app limits the negative effects of not receiving physiotherapist rehabilitation after ACL reconstruction. MATERIAL AND METHODS: We performed a case-control study involving the retrospective analysis of prospectively collected data from two groups of patients who had undergone ACL reconstruction surgery. Patients in the App group had surgery just before the 2-month COVID-19-related lockdown that started in France on March 17, 2020,and used only the smartphone app for rehabilitation. The standard-care group was composed of matched controls who had surgery 1 year before the cases and received rehabilitation therapy during in-person physiotherapist visits. The ACL reconstruction technique was the same in the two groups. The primary outcome measure was extension lag 6 weeks after surgery. The secondary outcome measures were extension lag 3 weeks and 6 months after surgery, quadriceps muscle activation, knee extension locking 3 and 6 weeks after surgery, and the 6-month rate of surgical revision for cyclops syndrome. RESULTS: We included 32 cases managed using only self-rehabilitation guided by the phone app, and we identified 101 matched controls managed using standard care. We found no significant between-group difference in extension lag after 6 weeks: 9.4% (28/32) vs. 4.6% (87/101), p=0.39. After 3 weeks, the App group had a higher proportions of patients with quadriceps activation (94% [30/32] vs. 73% [74/101], p=0.015) and extension control using canes (78.1% [25/32] vs. 40.6% [41/101], p=0.0002). None of the other measured outcomes differed significantly between the two groups (extension lag after 3 weeks: 12.5% [4/32] vs. 13.8% 14/101]; extension lag after 6 months: 3.2% [1/32] vs. 1% [1/101]; quadriceps activation after 6 weeks: 97% [31/32] vs. 99% [100/101]; extension locking with canes after 6 weeks: 96.9% [31/32] vs. 93.1% [94/101]; extension locking without canes after 3 weeks: 53.2% [17/32] vs. 47.5% [48/101]; extension locking without canes after 6 weeks: 93.7% [30/32] vs. 82.2% [83/101]; and surgery for cyclops syndrome (3.1% [1/32] vs. 1% [1/101]). DISCUSSION: The use of a self-rehabilitation phone app after ACL reconstruction during a COVID-19 lockdown limited the adverse effects of not receiving in-person physiotherapy. The 6-month outcomes were similar to those seen with standard rehabilitation. The study results demonstrate the usefulness of self-rehabilitation after ACL reconstruction surgery. Self-rehabilitation guided by a phone app could be used as a complement to the protocols generally applied by physiotherapists. LEVEL OF EVIDENCE: IV, single-centre retrospective case-control study.
