Recently, knotless adjustable suture anchor fixation has been introduced to treat root tears. This anchor-based fixation demonstrates less cyclic displacement than a TO repair. However, it is unknown how meniscal extrusion and contact mechanics compare between these 2 repair techniques when the meniscus endures cyclic tibiofemoral loading. Hypothesis: Suture anchor repair will demonstrate reduced meniscal extrusion and lower medial compartment pressure at the 1000th cycle compared with the TO repair. Study Design: Controlled laboratory study. Methods: Eight pairs of cadaveric knees were used to compare extrusion and contact pressure between transtibial fixation and suture anchor repair techniques for medial meniscus posterior root tears. Each specimen underwent cyclic compressive loading (0th, 100th, 500th, and 1000th cycles). Medial meniscal extrusion was assessed with the knee at full extension using ultrasound, and medial compartment contact pressures were evaluated using pressure sensors. Statistical analyses included paired <jats:italic>t</jats:italic> tests and repeated-measures analysis of variance with an alpha level set at .05. Results: The suture anchor repair technique demonstrated significantly lower absolute and relative medial meniscal extrusion compared with transtibial fixation repair after 500 and 1000 cycles of loading ( <jats:italic>P</jats:italic> = .012 and <jats:italic>P</jats:italic> = .001, respectively). Similarly, mean medial compartment pressures were significantly lower in the suture anchor repair group compared with the transtibial fixation repair group after 1000 cycles ( <jats:italic>P</jats:italic> = .028). No significant differences were found in peak pressures between the 2 repair techniques. Conclusion: The suture anchor repair demonstrated lower medial meniscal extrusion and reduced medial compartment contact pressures after time-zero cyclic loading. This biomechanical profile may be important for increasing the likelihood of healing and may translate to improved long-term outcomes for patients undergoing meniscus root repair. Clinical Relevance: Understanding the biomechanical differences between repair techniques at time zero may be crucial for optimizing surgical outcomes and minimizing the risk of long-term joint degeneration after meniscus root tears. Future clinical studies should further investigate these findings in live patient populations to validate their effect on root healing, functional outcomes, and long-term osteoarthritis progression.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640060","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}

While previous studies have identified the injuries experienced by elite goaltenders, these have been limited by the use of secondary data or data from small samples over relatively short time intervals.PURPOSETo quantify the type and number of injuries occurring in National Hockey League (NHL) goaltenders and the time lost due to these injuries.STUDY DESIGNDescriptive epidemiology study.METHODSData from the NHL's Athlete Health Management System was analyzed between the 2009-2010 and 2022-2023 seasons. The total number of each musculoskeletal injury, the total days missed (TDM) (a surrogate measure for injury severity), and the exposure-adjusted injury rate (EAIR) was quantified. For each individual diagnosis, the total number of injuries, mean, median, standard deviation, and minimum and maximum (range) TDM were calculated.RESULTSThere were 1585 musculoskeletal injuries recorded over 14 NHL seasons resulting in 31,406 TDM. The number of total injuries per year was stable across the data collection period. The EAIR was higher in the preseason (69.4) and postseason (46.8) compared with the regular season (17.1). The majority of the injuries occurred during games (n = 904), followed by practice and off-ice activities (n = 681). The most common mechanisms were noncontact (n = 673), incidental contact (n = 252), and \"unknown/other\" (n = 374). Proximal adductor injuries accounted for the largest number of injuries (n = 371), leading to the highest total TDM (n = 6126).

Patients were matched by age, gender, and handedness to patients from previously published modified Jobe and docking cohorts. The following were compared among groups: Conway Scale, Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score, years played, gender, handedness, sport, position, graft type (for reconstructive techniques), future upper extremity injury, need for additional surgery, rates of ulnar nerve symptoms, and return-to-play time.RESULTSPatients were similar with respect to age (P = .54), gender (P = .66), handedness (P = .29), sport (P = .23), years played (P = .72), level of competition (P = .08), type of pathology (P = .23), future shoulder surgery (P = .71), and future elbow surgery (P = .61).

Our null hypothesis was that there would be no differences in the tibial or femoral influence among the coronal alignment groups.STUDY DESIGNCase series; Level of evidence, 4.METHODSThe preoperative coronal alignment of patients undergoing primary ACL reconstructions were assessed retrospectively between June 2019 and July 2024. Patients were categorized into neutral, varus, and valgus groups based on their long-limb coronal mechanical axis. Coronal measurements were obtained, including the mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA), to determine individual alignment of the femur and the tibia. The neutral mLDFA and mMPTA were defined by a range within 1 standard deviation from the mean mLDFA and mMPTA values of the neutral group. Varus and valgus alignment were assessed, including if the variation originated from the tibia, the femur, or both. Comparisons to posterior tibial slope, sex, and concomitant injuries were analyzed.RESULTSThe study consisted of 250 patients (116 female). The mean mLDFA was 86.3° ± 1.7°, and the mean mMPTA was 87.3° ± 2.2°. The mean mechanical hip-knee-ankle angle and joint line convergence angle were 179.9° ± 2.9° and 1.3° ± 1.0°, respectively. On the basis of the mechanical axis, 113 patients were classified as having neutral alignment, 77 as having varus alignment, and 60 as having valgus alignment. The mMPTA was the primary cause of overall alignment in both the varus (54.5%) and valgus (65.0%) groups. Female patients had a significantly higher mMPTA than male patients (88.1° vs 86.7°, respectively), indicating less overall tibial varus alignment (P < .001), and there were significantly more female patients in the valgus group (P < .001). Concomitant meniscal, chondral, and ligament injuries displayed no significant associations between each coronal alignment group.CONCLUSIONThe present study found that overall varus and valgus alignment were influenced more often by the tibia, or the mMPTA, than by the femur, especially for valgus alignment. Additionally, female patients exhibited significantly more overall valgus alignment than male patients, with the tibia being the primary determinant of valgus alignment.

Patients who undergo ACLR are at a higher risk of undergoing knee arthroplasty and are at risk earlier than the general population. As patients with ACLR age and as ACLR surgery becomes more prevalent in the older athlete, the rates of knee arthroplasty after ACLR will only increase. Purpose: To determine the incidence of knee arthroplasty after ACLR, as well as identify patient and operative risk factors for knee arthroplasty after ACLR. Study Design: Cohort study; Level of evidence 3. Methods: Data from Kaiser Permanente’s ACLR Registry and Total Joint Replacement Registry were used to conduct a cohort study. Patients with primary ACLR were identified (2005-2022). Patient factors considered included age, body mass index (BMI), sex, race/ethnicity, smoking status, American Society of Anesthesiologists classification, activity at the time of injury, and medical comorbidities. Time from injury to ACLR, concomitant meniscal or chondral injuries, multiligament injury, graft type, and drilling technique were procedure factors evaluated. Postoperative factors included revision surgery, ipsilateral reoperation, and contralateral operation during follow-up. The outcome of interest was a subsequent knee arthroplasty. Patients were followed until the outcome of interest unless censored for membership disenrollment, death, or study end date (December 31, 2022).

However, this high failure rate is based on historical studies of patients with critical defects stabilized using older techniques.PURPOSETo evaluate the long-term clinical outcomes of arthroscopic Bankart repair using a contemporary technique with a minimum of 3 suture anchors in patients with traumatic anterior instability and to assess possible risk factors for recurrent instability.STUDY DESIGNCase series; Level of evidence, 4.METHODSA total of 181 patients (182 shoulders), who underwent arthroscopic Bankart repair because of traumatic anterior instability between 2005 and 2014, were included in this study and evaluated at a minimum follow-up of 10 years. Exclusion criteria were previous shoulder surgery, additional stabilization procedures, use of &lt;3 anchors, multidirectional instability, and indications for bony reconstruction (critical bony defects: glenoid defect &gt;20%, off-track Hill-Sachs lesion). The primary outcome was recurrent instability. Secondary outcomes were the Subjective Shoulder Value (SSV), visual analog scale (VAS), Constant score, Western Ontario Shoulder Instability Index (WOSI), and Rowe score as well as sports activity level and return to sports. Risk factors for recurrent instability were analyzed.RESULTSThe overall recurrence rate was 20.9% at a mean follow-up of 13.8 ± 2.8 years. Age ≤20 years at the time of surgery was associated with a higher risk of recurrence (P = .007). The failure rate was lower in patients who underwent surgery after the first-time dislocation (8/58 [13.8%]) compared with patients who underwent surgery after multiple instability events (30/124 [24.2%]), although this was not statistically significant (P = .108). Patients without recurrent instability had statistically significant better scores on the SSV (P &lt; .001), VAS for pain during movements (P = .016), Constant score (P = .011), WOSI (P = .001), and Rowe score (P &lt; .001) compared with patients with recurrence without revision surgery. A shorter interval between the first dislocation and surgery was associated with better shoulder outcomes, despite a consistent recurrence rate. Of all patients, 97.6% returned to sports, with 69.6% returning to 90% to 100% of their preoperative sports activity.CONCLUSIONArthroscopic Bankart repair resulted in a relatively high recurrence rate, despite the use of a contemporary technique, particularly in patients with &gt;1 dislocation before surgery. While younger age and a higher number of preoperative dislocations were potential risk factors for recurrence, a shorter interval between the first dislocation and surgery was associated with improved clinical outcomes.

Study Design: Cohort study; Level of evidence, 3. Methods: The study included all patients with primary unilateral ACLR enrolled in the Norwegian Knee Ligament Registry and Swedish Knee Ligament Registry from 2005 through 2008 (n = 15,783). At a mean follow-up of 10.1 years (SD, 0.2), 7040 (45%) patients completed the Knee injury and Osteoarthritis Outcome Score (KOOS). Multiple linear regression analyses were used to evaluate any associations between concomitant cartilage lesions and KOOS outcomes 10 years after ACLR. Results: Of the 7040 patients available at 10-year follow-up, 1425 (20.3%) had partial-thickness cartilage lesions at the time of ACLR, and 495 (7.0%) had full-thickness cartilage lesions. Multiple linear regression analyses revealed that partial- and full-thickness cartilage lesions were associated with significantly inferior scores across all KOOS subscales as compared with patients without cartilage lesions. Patients with full-thickness lesions had less postoperative improvement after ACLR in all KOOS subscales as compared with patients with partial-thickness lesions. Conclusion: Patients with concomitant partial- or full-thickness cartilage lesions reported significantly worse outcomes in all KOOS subscales 10 years after ACLR as compared with patients without cartilage lesions.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565764","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}

No existing literature directly compares the effectiveness of this technique with traditional single-plug circular OCA. Purpose: To compare failure rates, reoperation rates, and relevant patient-reported outcome (PRO) scores at 2-year follow-up between patients undergoing snowman OCA and patients undergoing single-plug OCA. Study Design: Case series; Level of evidence, 3. Methods: Patients who underwent snowman or single-plug OCA between 2001 and 2021 with a minimum 2-year follow-up were identified. Propensity score matching at 1:2 was performed based on age, sex, body mass index, defect location, and defect size. The PRO measures assessed included the International Knee Documentation Committee subjective score, Lysholm score, Knee Injury and Osteoarthritis Outcome Score, and 12-Item Short Form Health Survey. Failure was defined as conversion to arthroplasty, revision OCA, or graft degeneration on second-look arthroscopic examination. Additionally, rates of achieving the minimal clinically important difference (MCID) or patient acceptable symptom state (PASS) for PRO measures were determined. Results: There were 26 patients (mean age, 33.3 ± 9.3 years; 65.4% male) who underwent snowman OCA with a mean follow-up of 5.8 ± 4.1 years. No significant differences in baseline variables were identified compared with a matched control group of 52 patients who underwent single-plug OCA. No differences were detected in the rate of achieving the MCID or PASS between the groups for any PRO measure. Overall, 5 patients (19.2%) in the snowman group experienced graft failure at a mean 1.7 ± 1.0 years, while 10 patients (19.2%) in the single-plug group met the criteria for failure at a mean 6.6 ± 3.5 years. No differences were detected in the rate of failure or reoperations between the 2 groups. Conclusion: Multiplug “snowman” and single-plug circular OCA techniques yielded comparable clinical outcomes and graft survivorship for defects of a similar size in a matched cohort analysis. Defect shape, rather than size alone, should guide the selection of a technique. The snowman technique is advantageous for longer or oval-shaped defects not easily treated with a single plug, as it minimizes the removal of healthy cartilage while maintaining optimal outcomes.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565786","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}

In a previous study, arthroscopic labral repair (Bankart repair) reduced the risk of secondary shoulder dislocations and improved functional outcomes versus nonoperative treatment at 2-year follow-up. Purpose/Hypothesis: The aim of this study was to compare the results of arthroscopic Bankart repair and nonoperative treatment at a minimum of 6 years’ follow-up in patients aged ≤25 years. The hypothesis was that acute surgery would decrease the risk of recurrence and improve functional outcomes. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: We included patients aged between 18 and 25 years after a first episode of an ASD and divided them into 2 groups. The first group was treated surgically with arthroscopic Bankart repair in the initial 2 weeks after the dislocation, and the second group was treated nonoperatively. Both groups were immobilized for 3 weeks in internal rotation and followed the same physical therapy protocol. Follow-up was performed at a minimum of 6 years. The primary outcome measure was the recurrence of instability, defined as another ASD requiring closed reduction or a subluxation. Secondary outcome measures included the need for stabilization surgery; return to sport; and functional outcomes according to the quick version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), Walch-Duplay score, and Western Ontario Shoulder Instability Index (WOSI). Results: There were 20 patients included in each group. The mean age at the time of inclusion was 21.4 ± 1.8 years. A total of 37 patients were evaluated at a mean follow-up of 81.4 months (6.8 years). In the surgical group, the recurrence of instability (dislocation or subluxation) was significantly lower compared with the nonoperative group (n = 5 [27.8%] vs 17 [89.5%], respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; &lt; .0005), and the rate increased in both groups compared with 2-year results (n = 2 [10%] vs 13 [65%], respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; = .003). Fewer patients had another episode of a dislocation in the surgical group compared with the nonoperative group (n = 4 [22.2%] vs 15 [79.0%], respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; &lt; .003). In the surgical group, all dislocations occurred after 2 years’ follow-up, while 6 patients in the nonoperative group already had dislocations at 2 years. The Walch-Duplay score (93.24 vs 76.05 points, respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; = .0004), WOSI score (12.12 vs 20.95 points, respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; = .009), and QuickDASH score (4.84 vs 16.14 points, respectively; &lt;jats:italic&gt;P&lt;/jats:italic&gt; = .0088) were significantly better in the surgical group than in the nonoperative group.
