Adjustable suture anchor (ASA) fixation has yet to be evaluated through the loaded knee range of motion.HYPOTHESISThe ASA PMMR repair would restore meniscal translation similar to the native meniscus and maintain those parameters through the knee flexion arc during cyclical axial loading.STUDY DESIGNControlled laboratory study.METHODSEight cadaveric knees from 6 donors (4 men, 2 women; mean age, 44.9 years) were tested. Each knee was tested for meniscal translation in 3 conditions: intact, posterior root released, and root repair. The repairs were fixed with an ASA device in a Mason-Allen configuration with knotless repair sutures. In each condition, the knees were axially loaded with 30 N through a range of motion to test meniscal excursion, extrusion, and hoop strain at 0°, 30°, 60°, 90°, and 100° of flexion for 10 cycles. Each parameter was compared for statistical significance using repeated-measures analysis of variance (ANOVA) or 1-way ANOVA, followed by Tukey post hoc tests.RESULTSExtrusion was significantly elevated in the PMMR released group compared with the native and repaired conditions at full extension (P = .0008), 30° (P = .007), 60° (P = .0008), 90° (P = .00006), and 100° (P = .0005). Extrusion in the ASA repaired condition was similar to, or less than, the native condition across every position. Meniscal hoop strain in the repaired and intact groups was significantly increased compared with the released group (P = .0009). Meniscal excursion was significantly greater with root release compared with intact and repaired groups at 30° (P = .001), but less in the native condition at 60° (P = .021) and 100° (P = .018).CONCLUSIONPMMR ASA repair resulted in decreased excursion and extrusion compared with the meniscal root tear condition, extrusion, and hoop strain approximated that of native, intact meniscus through axial loading and knee range of motion in a human cadaveric model.CLINICAL RELEVANCEASA PMMR demonstrated meniscal translation similar to that of the native meniscus under loading during knee motion, which could potentially enable more accelerated postsurgical rehabilitation. Future studies may define the clinical significance of healing rates and long-term outcomes.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"2 1","pages":"3635465251405733"},"PeriodicalIF":0.0,"publicationDate":"2026-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146072982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As TKA use increases in younger patients, return to sports (RTS) has become a key outcome measure. While RTS rates after TKA are generally high, they vary significantly across studies due to differences in study design, patient populations, and RTS definitions.PURPOSETo determine RTS rates, evaluate return to preoperative sport levels, quantify time to RTS, and identify factors affecting RTS after TKA.STUDY DESIGNCohort study; Level of evidence, 2.METHODSWe analyzed 21,466 primary TKAs performed between 2016 and 2022. Of these, 1782 patients (8.3%) were athletes at baseline, with 1464 (82.2%) completing 1-year follow-up. We recorded demographic characteristics, comorbidities, baseline and 1-year RTS status, time to RTS, athlete type, and patient-reported outcomes. Analysis included descriptive statistics, Cox regression for time to RTS, and logistic regression for RTS-associated factors.RESULTSOf 1464 patients, 782 (53.4%) achieved RTS, while 676 (46.6%) did not; both contact and noncontact sports were included. Among those who returned, 62% resumed their previous sport at the same level, 34.5% at a reduced intensity, and 3.4% switched to a different sport. The median RTS time was 12 weeks, with 90% returning within 27 weeks. Medicaid patients had a delayed RTS compared with those with commercial insurance (hazard ratio [HR], 0.51). Overweight patients returned sooner than normal-weight patients (HR, 1.41). Female patients (odds ratio [OR], 0.76) and Black patients (OR, 2.34) had lower RTS odds, while recreational (OR, 0.06) and competitive athletes (OR, 0.10) had higher RTS odds versus those not participating in athletic activities.CONCLUSIONOver half of athletes returned to sports within 1 year of TKA, most within 27 weeks. RTS rates varied by preoperative competitive level, sex, race, body mass index, and comorbidity burden. These findings can guide patient expectations and shared decision-making regarding post-TKA sports participation. Future research should focus on improving RTS rates in high-risk groups, standardizing RTS criteria, and stratifying outcomes by sport type and impact level to enable more individualized patient recommendations.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"88 1","pages":"3635465251400357"},"PeriodicalIF":0.0,"publicationDate":"2026-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146069960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PubMed, Embase, and Scopus databases were queried on February 2, 2025. Original outcome studies on arthroscopic hip labral reconstruction with clearly delineated graft type and a mean follow-up of at least 1 year were included. Studies with a mean follow-up <1 year, nonarthroscopic labral reconstruction, or unclear graft-specific outcomes were excluded. Data were extracted from 30 studies (1968 hips: 1071 autograft, 897 allograft). A random-effects meta-analysis was performed using RStudio to assess patient-reported outcomes, revision surgery, and complication rates.RESULTSThere were no significant differences in most patient-reported outcomes: Harris Hip Score (allograft: 27.5 vs autograft: 24.6; P = .17), Hip Outcome Score (HOS) Activities of Daily Living (20.9 vs 22.8; P = .59), HOS Sports (33.2 vs 34.0; P = .65), SF-12 Physical score (10.0 vs 7.0; P = .19), and visual analog scale pain score (-3.5 vs -4.2; P = .34). The SF-12 Mental score improvement was significantly higher in the allograft group (5.2 vs 0.0; P = .03), although sample size was limited. Complication rates approached significance favoring allografts (<1% vs 3%; P = .06). No significant differences were observed in revision arthroscopy (1% allograft vs 5% autograft; P = .07) or conversion to total hip arthroplasty (3% vs 7%; P = .20).

Medial hamstring (HS) tendons are the most common autografts. An abnormal mediolateral HS muscle activation pattern after ACLR with an HS autograft could influence return to sport (RTS).PURPOSETo evaluate patients who underwent ACLR with concurrent isokinetic tests and surface electromyography (sEMG) of the medial versus lateral HS compared with a group of healthy controls to identify potential abnormal patterns at RTS.STUDY DESIGNComparative study; Level of evidence, 3.METHODSThe mean medial versus lateral HS sEMG amplitude and timing were measured during isokinetic tests at 60, 180, and 300 deg/sec in 92 participants: 46 patients who underwent primary HS-grafted ACLRs (ACLR group) and 46 healthy controls matched for age (18-45 years), sex, and level of physical activity (Tegner, 4-9) (control group). After the 8th postoperative month, the ACLR group were evaluated with an isokinetic test combined with sEMG of the medial and lateral HS. The control group were tested with the same procedure. sEMG data were included only if the minimum criteria for RTS were met according to the published literature (HS/quadriceps ratio ≥60% and quadriceps and HS interlimb peak torque difference at 60, 180, and 300 deg/sec ≤10%).RESULTSThere was no difference in isokinetic peak torque normalized to body mass between ACLRs and controls at any tested angular velocity. The mean sEMG amplitude for both the medial and lateral HS showed no between-group difference at 60, 180, and 300 deg/sec. No intergroup differences emerged for the mediolateral HS ratio during all tests. Instead, the mean sEMG time-to-peak for the medial HS was consistently faster in the ACLR group (P = .02 at 60 deg/sec; P = .01 at 180 deg/sec; P = .04 at 300 deg/sec), with no intergroup difference for the lateral HS at 60, 180, 300 deg/sec.CONCLUSIONThe grafted medial HS showed consistently faster sEMG time-to-peak in the ACLR group than in the control group at all tested velocities. No differences emerged on sEMG amplitude for the medial HS and on both sEMG amplitude and timing for the lateral HS. Those who underwent HS-grafted ACLR showed a higher neuromuscular demand on the grafted medial HS at RTS. This altered overall HS muscle coordination could affect lower limb biomechanics during active movements, potentially increasing the risk of ACL reinjury.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"71 1","pages":"3635465251404915"},"PeriodicalIF":0.0,"publicationDate":"2026-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146070075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving this length is not always feasible. Purpose: To evaluate graft healing and clinical outcomes in patients with an intraoperative FTGL target of 10 to 15 mm, and to investigate whether shorter postoperative magnetic resonance imaging (MRI)–measured FTGL (mFTGL) within this cohort affected outcomes through subgroup analysis. Study Design: Case series; Level of evidence: 4 Methods: The records of patients who underwent primary single-bundle ACLR using a quadrupled semitendinosus autograft and ALLR using a gracilis autograft, with a minimum 2-year follow-up, were retrospectively reviewed. During surgery, the FTGL was intentionally set to fall within the 10- to 15-mm range. Postoperatively, the graft length within the femoral tunnel was measured on postoperative day 2 MRI (mFTGL) and used for analyses. Graft healing was evaluated using 6-month MRI scans: (1) graft incorporation, assessed by the signal-to-noise quotient (SNQ) at the tunnel (SNQ_tunnel), signal intensity at the graft-bone interface, and tunnel widening; and (2) graft ligamentization, assessed by the SNQ of the graft (SNQ_graft) and Howell grade. Clinical outcomes were also assessed. For subgroup analysis, patients were classified into group 1 (mFTGL ≤12.6 mm) and group 2 (mFTGL &gt;12.6 mm). Results: A total of 180 knees were consecutively enrolled; 169 completed the 6-month MRI evaluation. The graft failure rate was 3.9%. The mean mFTGL was 12.6 ± 2.6 mm. In subgroup analysis, the femoral SNQ_tunnel difference between the tunnel aperture and proximal site was 0.9 ± 3.3 for group 1 and 2.3 ± 3.9 for group 2 ( <jats:italic toggle=\"yes\">P</jats:italic> = .014). Femoral tunnel widening was 60.1% ± 30.7% for group 1 and 74.3% ± 37.2% for group 2 ( <jats:italic toggle=\"yes\">P</jats:italic> = .008). In multiple regression analysis, mFTGL (β = 3.28; <jats:italic toggle=\"yes\">P</jats:italic> &lt; .001) and graft diameter (β = −23.86; <jats:italic toggle=\"yes\">P</jats:italic> &lt; .001) were independently associated with femoral tunnel widening. Conclusion: In combined ACLR and ALLR, an intraoperative FTGL target of 10 to 15 mm was clinically acceptable regarding graft failure, graft healing, and clinical outcomes. The subgroup with shorter FTGL showed less femoral tunnel widening.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146056185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
