Purpose To evaluate the clinical outcomes of patients with increased posterior tibial slope (PTS ≥12°) undergoing primary anterior cruciate ligament reconstruction (ACLR) with concomitant lateral extra‐articular tenodesis (LET) and to determine whether the addition of LET mitigates the elevated risk of graft failure associated with increased tibial slope. Methods This single‐center retrospective cohort study included patients ≥16 years who underwent primary ACLR with LET between 2013 and 2022 with a minimum 2‐year follow‐up. Patients were stratified by PTS ≥12° versus <12° and required preoperative lateral radiographs for slope measurement and high‐risk features (pivot shift ≥2, Beighton ≥4, or return to pivoting sports). Outcomes included graft failure, residual pivot shift, complications, and patient‐reported outcomes (International Knee Documentation Committee and Lysholm). Achievement of minimal clinically important difference was assessed. Multivariable logistic regression and Cox proportional hazards analysis were performed to identify independent predictors of graft failure. Results A total of 289 patients (mean follow‐up, 38 months) were included: 45 with PTS ≥12° (13.0° ± 1.2°) and 244 with PTS <12° (8.1° ± 1.5°). Graft failure occurred in 24% versus 18%, respectively ( P = .411). On multivariable Cox proportional hazards analysis, no independent predictor of graft failure was identified, including PTS (hazard ratio, 1.07 per degree; 95% confidence interval, 0.95‐1.19; P = .260). Complications and contralateral anterior cruciate ligament injury rates were similar between groups. On sex‐disaggregated analysis, similar patterns were observed in both male and female cohorts, with no significant between‐group differences in graft failure, retear, or complication rates by tibial slope. Patient‐reported outcomes were comparable at all time points. At final follow‐up, minimal clinically important difference achievement for International Knee Documentation Committee and Lysholm was 98% and 100%, respectively, with no between‐group differences. Conclusions In high‐risk patients with a PTS of ≥12°, primary ACLR with LET led to similar clinical results as patients with a PTS of 12 or less. A PTS of ≥12° may be considered an indication for the addition of an LET during primary ACLR. Level of Evidence Level III, retrospective comparative case series.

Purpose The purpose of this study was to compare graft failure and clinical outcomes following primary anterior cruciate ligament reconstruction (ACLR) using quadriceps tendon autograft (QA), with or without a modified Lemaire lateral extra‐articular tenodesis (LET). Methods Patients with ACL deficiency who underwent primary QA ACLR with or without LET and completed at least 2‐year follow‐up were included. Patients with a Beighton score ≥4, a preoperative pivot shift grade ≥2, or an intention to return to cutting and pivoting sports were offered LET. The primary outcome variable assessed was graft failure as defined by graft rupture or grade ≥2 pivot shift at any point postoperatively. Secondary outcomes included return to sport clearance rates, the International Knee Documentation Committee and Lysholm scores and postoperative complications. Results There were 122 undergoing QA ACLR with LET (QA + LET group) and 152 undergoing isolated QA ACLR (QA group). The QA + LET group had a significantly lower failure rate of 14.8% versus 29.6% in the QA group ( P = .02). In addition, the QA + LET group had a lower residual pivot shift rate compared with the QA group (11.3% vs. 26.3% respectively; P = .01). There was no difference in graft retear rates between the 2 groups ( P = .37). The QA + LET returned to sport significantly faster at 8.8 months compared with 9.7 months in the QA group ( P = .038). Conclusions The addition of LET to QA ACLR was associated with a significantly lower overall graft failure rate and lower percentage of patients with residual pivot shifts after ACLR compared with QA alone at 2‐year follow up. However, there was no difference between the 2 groups with regard to graft retear rates. The addition of an LET to QA ACLR also allowed athletes to return to sports faster compared with QA alone.

Purpose To determine if preoperative femoral or tibial bone marrow edema (BME) is indicative of higher rates of re‐tear and conversion to total knee arthroplasty (TKA) after posterior medial meniscal root tear repair, and, secondarily, whether preoperative BME impacted patient‐reported outcome measures and rates of infection and arthrofibrosis. Methods Patients that underwent posterior medial meniscal root tear repair between 2013 and 2021 with a 2‐year minimum follow‐up were retrospectively analyzed. Primary outcome measures included re‐tears and TKA conversion. Secondary outcomes included International Knee Documentation Committee (IKDC) score and Lysholm score, infection, and arthrofibrosis. Cohort‐specific minimally clinically important difference and Patient Acceptable Symptomatic Scale rates were calculated. Two‐tailed t‐tests, Wilcoxon rank‐sum tests, and Fisher's exact tests were used where appropriate. Results The study population consisted of 97 knees (74 without BME [NBME], 23 with BME) with average follow‐up of 38.9 months (24‐68). Preoperatively, the NBME group had higher IKDC scores ( P = .008). Postoperatively, the NBME group had higher IKDC scores at 6 months, 1 year, and 2 years (84.5 [6.0] vs 68.5 [11.0]) ( P = .041, <.001, <.001). IKDC minimally clinically important difference rates were not significantly different between groups at all follow‐ups. Patient Acceptable Symptomatic Scale rates were higher for the NBME group at 1‐year and final follow‐up (100.0% vs 60.9%) ( P < .001 for both). Lysholm scores were higher for the NBME group at 1‐year and final follow‐up (84.0 [5.6] vs 74.6 [12.8]) ( P = .019 and .008, respectively). Re‐tear occurred in 17.4% of the BME group and 0% of the NBME group ( P = .003). TKA conversion rates were 21.7% in the BME group and 2.7% in the NBME group ( P = .008). There was no difference in arthrofibrosis or infection rates. Conclusions Preoperative BME in patients undergoing posterior medial meniscal root tear repair is associated with higher rates of recurrent meniscal root tearing and conversion to TKA in addition to lower subjective IKDC and Lysholm scores compared to patients without preoperative BME.

Purpose To compare clinical outcomes between augmented subchondral drilling (aSCD) and nonsubchondral drilling (NoSCD) techniques, both using a cartilage scaffold, in the treatment of isolated patellar cartilage lesions. Methods A retrospective cohort study was conducted on patients who underwent surgical treatment for isolated patellar cartilage using either an aSCD technique (a subchondral drilling augmented with a particulated cartilage allograft scaffold or a flexible osteochondral allograft scaffold) or a NoSCD technique (a particulated juvenile articular cartilage scaffold or a flexible osteochondral allograft scaffold implanted without performing a subchondral drilling). Patients were included if they had a minimum 2‐year follow‐up and excluded if they underwent concomitant meniscal or ligamentous procedures. While tibial tubercle osteotomy (TTO) was commonly performed, it was not a strict inclusion criterion. All procedures were performed through arthrotomy with a standardized postoperative rehabilitation protocol. Clinical outcomes included International Knee Documentation Committee (IKDC) and Lysholm scores, reoperation rates, conversion to total knee arthroplasty, and complications. Results A total of 65 knees were included: 31 in the aSCD group and 34 in the NoSCD group, with a mean follow‐up of 50.4 months (range, 24‐88 months). In the aSCD group, particulated allograft cartilage hydrated with platelet‐rich plasma was used in 80.7% of cases and flexible osteochondral allograft in 19.3%, while the NoSCD group was treated with Cartiform (Arthrex) in 70.6% and particulated juvenile articular cartilage in 29.4% of cases. TTO was performed in 87.0% of aSCD and 91.2% of NoSCD cases. Average defect sizes were 3.7 cm 2 (aSCD) and 4.0 cm 2 (NoSCD). At final follow‐up, the NoSCD group had significantly better outcomes, with higher median IKDC scores (81.0 vs 74.0; P < .001) and median Lysholm scores (83.0 vs 77.0; P < .001). A significantly greater proportion of NoSCD patients exceeded the minimal clinically important difference for IKDC (100% vs 80.6%; P = .024) but not for Lysholm (97.1% vs 93.5%; P = .935) at final follow‐up. In multivariable regression adjusting for scaffold type, TTO, and defect size, aSCD remained a significant independent predictor of lower final IKDC (β = –8.97; P = .001) and Lysholm (β = –12.71; P < .001) scores. The aSCD group had a significantly higher rate of repeat surgery (45.2% vs 14.7%; P = .015). There was no significant difference in conversion to total knee arthroplasty between groups ( P = .432). Conclusions For the treatment of isolated patellar cartilage lesions, a nonsubchondral drilling technique with scaffolding was associated with improved patient‐reported outcomes and fewer complications compared to a subchondral drilling technique with scaffolding, although there was no difference in the rate of conversion to total knee arthroplasty.

Background: Chronic hamstring tears can result in challenging surgical repairs. Allografts may be used to augment the repair; however, there is limited clinical evidence supporting their use. Purposes: To (1) evaluate clinical outcomes of patients who underwent proximal hamstring repair with allograft augmentation or interposition and (2) compare them to matched controls who underwent primary hamstring repair. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 117 patients who underwent proximal hamstring repair were included, consisting of 19 allograft augmentations, 20 allograft interpositions, and 78 primary repairs. Allograft cohorts were propensity-matched with those who underwent primary repair in a 1 to 2 ratio. Clinical outcomes were obtained at the final follow-up. Data were extracted using continuous variables, with normality reported as mean values ± standard deviation, and non-normality reported as median values with interquartile ranges (IQR). Results: The median follow-up of the augmentation cohort was 1.9 [IQR, 0.8-3.9] years, while it was 3.2 [IQR, 1.6-5.1] years ( P = .182) for the primary repair cohort. The mean follow-up for the interposition cohort was 3.5 ± 2.4 years, while it was 4.2 ± 2.5 years for the primary repair cohort ( P = .227). Forty-two percent of the augmentation cohort had undergone previous surgery, compared with 5% of the interposition cohort. The time from injury to surgery for the augmentation and primary repair cohorts was 6.4 and 1.3 months, respectively ( P < .001). For the interposition and primary repair cohorts, the durations were 17.8 and 1 months, respectively ( P < .001). Clinical outcomes, including the Tegner Activity Scale (3 vs 3), pain with activity (47.4% vs 23.7%), and muscle spasms (36.8% vs 26.3%), did not show significant differences between the augmentation and primary repair cohorts. The augmentation cohort had a significantly worse Lower Extremity Functional Scale (LEFS) score (64 vs 75; P < .001) and were more likely to experience pain with sitting (52.6% vs 21.1%; P = .034) than the primary repair cohort. There was no significant difference in clinical outcomes between the interposition and primary repair cohorts (LEFS: 69 vs 75.5, Tegner Activity Scale: 4 vs 4; pain with sitting: 26.3% vs 27.5%; pain with activity: 42.1% vs 30%; muscle spasms: 26.3% vs 30%). Revision rates were similar between cohorts ( P ≥ .255). Conclusion: Proximal hamstring repair for chronic tears with allograft augmentation or interposition is a reproducible procedure that results in satisfactory, yet poorer clinical outcomes compared with patients who underwent primary hamstring repair. These procedures should be considered in symptomatic patients with chronic tears that are not amenable to primary repair.

Objectives: Prior literature has shown female soccer athletes are at a higher risk for anterior cruciate ligament (ACL) rupture. This risk persists even after primary ACL reconstruction (ACLR), given increased graft failure rates seen in this population. Thus, augmentation strategies such as lateral extra-articular tenodesis (LET) have gained increasing attention, but there is limited data in high-risk female soccer. The primary outcome of this study was to compare the graft failure rates and patient outcomes of ACLR with LET augmentation compared to isolated ACLR in female soccer players. Methods: A cohort of female soccer athletes who underwent ACLR was retrospectively analyzed. Participants were divided into two groups: those who received ACLR alone (control) and those who received ACLR with LET. Exclusion criteria included patients who were not involved in competitive soccer at the time of surgery or had less than 2-years follow-up. Patient demographics and physical exam findings, including the pivot shift results, were collected. Patient outcomes included graft failure, International Knee Documentation Committee (IKDC) and Lysholm scores, return to sport rates, and complications. Independent t-tests and chi-squared tests were conducted to compare outcomes between the two groups. Results: A total of 133 female soccer players who underwent ACLR and met inclusion criteria were identified, with 43 patients receiving LET and 90 patients undergoing sole ACLR. The LET cohort had a higher mean Beighton score (3.0 vs. 1.5; P<0.001) and greater proportion of generalized ligamentous laxity (48.8% vs. 18.9%; P<0.001). There were no significant differences between the two cohorts in age, level of competition, type of graft used, or meniscal intervention (P>0.05). Average follow-up was 39.0 and 36.1 months in the LET group and the control group, respectively. Final postoperative IKDC scores were greater in patients who received LET compared to those who did not (91.3 vs. 88.3; P=0.012). Further, there was a lower rate of graft failure, indicated by a confirmed ACL re-tear or a positive post-operative pivot shift, in patients who underwent LET compared to the control group (14% vs. 31.1%; P=0.036). The presence of positive post-operative pivot shift was also lower in the LET group compared to the control (9.3% vs. 27.8%; P=0.023). There were no significant differences in the rates of complications between the two groups (P>0.05), except for 9.3% of the LET patients developing a hematoma at the LET site. Conclusions: LET augmentation in ACLR is associated with a reduced graft failure rate and decreased post-operative rotational instability in female soccer athletes regardless of graft type used. This augmentation strategy may enhance the stability of the knee joint and help improve clinical outcomes, suggesting its potential as a standard adjunctive procedure for female soccer players undergoing primary ACLR.

Objectives: To compare ACL reconstruction with quadriceps autograft with or without LET for primary ACL reconstruction Methods: A retrospective study was performed from 2013- 2021 including patient undergoing quadriceps autograft (QA) or QA plus lateral extra-articular tenodesis (LET) for primary ACLR. Exclusion criteria included patients undergoing multi-ligamentous reconstruction, concomitant procedures outside of meniscal work, revision cases, and patients with less than 2 years of follow up. The surgeon favored LET in young (less than 18 years old) females participating in cutting and twisting sports. An additional relative indication was a high-grade pivot shift (2 or 3+). Clincal outcomes incldued IKDC and Lysholm scores, retrun to sport/return to sport at same level and time to return to sport in athletes along with complication rates. Failure rate was determined by rate of graft re-tearing and presence of a residual pivot shift (2+ or higher) at final follow up. Results: A total of 142 patients underwent QA+LET with 18 excluded, leaving 124 patients in this group. The QA group had 371 patients with 57 excluded, leaving 314 for analysis. The QA+LET group had a significantly higher percentage of females, ligamentous laxity, and athletes. IKDC scores were significantly higher in the QA+LET group at final follow up. Lysholm scores were significantly higher in the QA group at 6 months, with no difference at other time points. Graft re-tear rates were similar between the 2 groups. Residual pivot shift at final follow up was significantly higher in the QA group (21% vs. 11%, p = 0.012) as was overall failure rate (24% vs. 14.5%. p = 0.026). Return to sport was similar between the 2 groups, but time to return to sport and return at the same or higher level was significantly higher in the QA+LET group. Hematomas were more common (12.9% vs. 0%) in the QA+LET group. Conclusions: Addition of an LET to QA leads to lower residual pivot shift when compared to QA alone. The addition of a LET to QA may lead to a higher return to sport at same or higher level compared to QA alone. This provides preliminary data that will be built upon with results from the Stability 2 trial.

Objectives: Tobacco use is a known modifiable risk factor for postoperative complications and revision surgery after anterior cruciate ligament reconstruction (ACLR). Prior studies focus on “tobacco” as a broad categorization of traditional cigarette smoking, smokeless tobacco, and other forms of nicotine use. It is unclear if differences in the type of nicotine used lead to similar adverse outcomes after ACLR. Thus, the purpose of this study was to (1) assess the incidence of postoperative complications among ACLR patients who use smokeless tobacco, and (2) compare these outcomes with those of patients who do not use tobacco and those who smoke cigarettes. Methods: A retrospective cohort study utilizing a large insurance database was conducted. Patients undergoing primary ACLR without concomitant knee procedures with a minimum 2-year follow-up were included. Smokeless tobacco only users, cigarette only users, and non-tobacco users were matched based on demographic variables and comorbidities. Postoperative complications within 90 days of surgery and subsequent knee surgery within 2 years were compared among groups. Multivariable logistic regressions were employed to control for confounding variables. Results: After applying exclusion criteria, there were 241,194 ALCR patients eligible for analysis. Of these, there were 898 (0.37%) patients that used smokeless tobacco only, 22,062 (9.1%) patients that exclusively used cigarettes, and 207,462 (86%) patients that did not use any tobacco products. Compared to non-users, smokeless tobacco users demonstrated increased risk of emergency department (ED) utilization (20.4% vs 8.7%, OR: 6.29; 95% CI: 3.70-10.9, p<0.001), pneumonia (1.2% vs 0.5%, OR: 3.36; 95% CI: 1.41-7.90, p=0.005), and acute kidney injury (AKI) (1.2% vs 0.1%, OR:12.7; 95% CI: 3.77-52.8, p<0.001) within 90 days of surgery. Additionally, smokeless tobacco users had a markedly increased risk of subsequent ACLR (13.5% vs 3.2%, OR: 4.75; 95% CI: 3.60-6.26, p<0.001) and meniscus surgery (12.9% vs 4.9%, OR: 2.89; 95% CI: 2.23-3.73, p<0.001) within 2 years compared to controls. When compared to cigarette smokers, smokeless tobacco users showed increased risk of ED visits (20.6% vs 19.3%, OR: 1.55; 95% CI: 1.25-1.90, p<0.001), pneumonia (1.2% vs 0.6%, OR: 3.25; 95% CI: 1.33-7.78, p=0.008), and AKI (1.3% vs 0.3%, OR: 7.63; 95% CI: 2.72-22.5, p<0.001) within 90 days. They also demonstrated a significantly increased risk of subsequent ACLR (13.4% vs 4.1%, OR: 4.81; 95% CI: 3.58-6.47, p<0.001) and meniscus surgery (12.8% vs 5.5%, OR: 2.45; 95% CI: 2.45-4.26, p<0.001) within 2 years when compared to cigarette smokers. Conclusions: Smokeless tobacco use was associated with increased risk of medical complications, ED utilization, and subsequent procedures compared to non-user controls and traditional smokers. These findings highlight the importance of considering specific forms of tobacco use in preoperative screening for patients undergoing ACLR.

Abstract Like all diagnoses and comorbidities, patients with hip pain should be managed with individualized treatment plans. Patients with fibromyalgia undergoing hip arthroscopy are no different. Even if their absolute scores remain lower than those without fibromyalgia, these patients can achieve clinically meaningful improvements in patient‐reported outcomes after treatment of femoroacetabular impingement. As orthopaedic providers, we should be aware of potential bias against patients with chronic musculoskeletal pain and critically evaluate the literature that supports clinically relevant improvement after surgical intervention. Fibromyalgia should not be viewed as a condition that excludes or increases the threshold for hip arthroscopy but rather as a factor requiring nuanced, multidisciplinary perioperative care and realistic goal‐setting.

Background: The number of multiply revised anterior cruciate ligament reconstructions (rrACLRs) performed each year continues to increase. The most reliable graft type and surgical technique in the young, active patient remains to be determined. Purpose: To determine the outcomes of rrACLR using quadriceps tendon (QT) autograft with lateral extra-articular tenodesis (LET). Study Design: Case series; Level of evidence, 4. Methods: A retrospective review was performed of all competitive athletes undergoing rrACLR with QT autograft and LET at a single institution with a minimum follow-up of 2 years. Patient demographics, physical examination, and radiological findings, and previous surgical details were documented. Patient outcomes were noted, including the International Knee Documentation Committee (IKDC) and Lysholm scores, ability to return to sport and return at the same level of play, retear rate, and other complications. Results: A total of 19 rrACLRs were performed and met inclusion criteria in the 10-year study period. All participants were high school, collegiate, or professional athletes with a mean age of 22 years, and 63.2% were female. The mean follow-up was 42.3 months, and IKDC scores increased from 51.6 preoperatively to 74.7 at the final follow-up ( P < .001). Likewise, the Lysholm score increased significantly from a preoperative value of 53.6 to 76.8 at the final follow-up ( P < .001). Return to play was possible in 52.6% of the patients at a mean of 11.5 months, with 31.6% returning to the same or higher level of play. One (5.3%) patient experienced a recurrent ACL tear, and 2 (10.5%) experienced a contralateral tear. Arthrofibrosis requiring surgical intervention occurred in 26.3% of the athletes. Conclusion: Short- to midterm results demonstrated that competitive athletes who received an rrACLR using a QT autograft with LET had statistically significant improvements in both IKDC and Lysholm scores, with more than half of patients being able to return to sport and nearly a third returning at the same or higher level of play. In the setting of a third ACL reconstruction, quadriceps tendon autograft with LET is a reasonable option even in high-risk patients.
