All procedures were performed by a radiologist with 7 years of diagnostic US experience, limited previous US-guided interventional exposure, and no experience in hip joint injection. Primary outcomes were first-attempt success (successful intra-articular access and injection on the initial insertion without needle withdrawal or redirection) and final success (successful completion within no more than 2 insertion attempts). Secondary outcomes included puncture time, needle adjustments, operator confidence score, and complication. Learning curves were analyzed using cumulative sum (CUSUM) modeling for puncture time (seconds).</p><p><strong>Results: </strong>Compared with the single-plane group, the biplane group had significantly higher first-attempt success rate (48.6% vs 25.7%; relative risk [RR], 1.889 [95% CI, 1.103-3.648]; <i>P</i> = .048) and final success rate (91.4% vs 71.4%; RR, 1.280 [95% CI, 1.014-1.616]; <i>P</i> = .031). The biplane group also had shorter puncture time (median, 120 [interquartile range, IQR, 64-182] vs 153 [90- 234] seconds; <i>P</i> = .020), fewer needle adjustments (median, 1 [IQR, 0-2] vs 2 [0-3]; <i>P</i> = .008), and higher operator confidence score (median, 2 [IQR, 1-3] vs 1 [1-2]; <i>P</i> = .043).

Patients undergoing revision procedures or those who underwent concomitant procedures at the time of either Latarjet or arthroscopic Bankart repair were excluded. Functional outcomes (Constant and Rowe scores), subjective instability, dislocation, and reoperation rates were recorded.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 104 patients met inclusion criteria, of whom 53 underwent the Latarjet procedure and 51 underwent arthroscopic isolated Bankart repair. The mean follow-up duration was comparable between groups (Latarjet: 69.4 ± 20.6 months; Bankart: 69.9 ± 19.0 months; &lt;i&gt;P&lt;/i&gt; = .90). Patients in the Latarjet group were younger (23.3 ± 4.6 vs 25.7 ± 5.3 years; &lt;i&gt;P&lt;/i&gt; = .01) and more frequently engaged in manual labor (81.1% vs 33.3%; &lt;i&gt;P&lt;/i&gt; &lt; .001). Functional outcomes were favorable in both groups, with significantly higher Rowe scores observed in the Latarjet group (94.0 ± 2.9 vs 86.3 ± 19.2; &lt;i&gt;P&lt;/i&gt; = .004), while Constant scores were comparable. Postoperative subjective instability was reported less frequently after Latarjet compared with Bankart repair (39.6% vs 62.7%; &lt;i&gt;P&lt;/i&gt; = .02), although mean time to resolution did not differ significantly (19.6 vs 28.0 months; &lt;i&gt;P&lt;/i&gt; = .09). Persistent subjective instability at final follow-up was observed at similar rates between groups (13.2% vs 15.7%; &lt;i&gt;P&lt;/i&gt; = .71). Redislocation rates were significantly lower in the Latarjet group (3.8% vs 17.6%; &lt;i&gt;P&lt;/i&gt; = .02), with a longer mean time to dislocation (56.5 vs 30.0 months; &lt;i&gt;P&lt;/i&gt; = .004). Revision surgery rates did not differ significantly between groups. Cox proportional hazards regression demonstrated that surgical technique was a significant predictor of postoperative dislocation, with Latarjet associated with a lower hazard of dislocation (hazard ratio, 0.139; 95% CI, 0.026-0.737; &lt;i&gt;P&lt;/i&gt; = .02), whereas time to resolution of subjective instability was not predictive of dislocation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The sense of postoperative instability was common and occurred more frequently after isolated arthroscopic Bankart repair than after the Latarj","PeriodicalId":19646,"journal":{"name":"Orthopaedic Journal of Sports Medicine","volume":"14 8","pages":"23259671261470584"},"PeriodicalIF":2.9,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13469541/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148760600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These injuries can be debilitating for professional soccer players, leading to prolonged recovery and potential performance declines.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Purpose: &lt;/strong&gt;To investigate the annual incidence, return-to-play (RTP) duration, and postinjury performance outcomes of Major League Soccer (MLS) players who sustained Achilles tendon injuries from 2010 to 2021.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study design: &lt;/strong&gt;Cohort study; Level of evidence, 3.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This retrospective matched-cohort study evaluated MLS players with Achilles tendon injuries from 2010 to 2021, identified through the MLS Injury Surveillance database, and compared outcomes, including RTP duration, between players with ruptured and nonruptured (soreness, contusion, inflammation, irritation, sprain, tendinosis, tendinitis) injuries. Uninjured controls were matched 2:1 by age, position, and MLS experience. Annual injury incidence, RTP duration, and performance metrics, including games played, minutes played, goals, assists, and defensive contributions, were compared between injured and control cohorts. Multivariate linear regression was performed to identify independent predictors of RTP duration, adjusting for age, player position, injury type, mechanism of onset, field type, weather condition, and injury period. Statistical analyses set significance at &lt;i&gt;P&lt;/i&gt;≤ .05.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The mean RTP for ruptured Achilles injuries (n = 20) was 229 days, with no significant difference between 2010-2015 and 2016-2021 (&lt;i&gt;P&lt;/i&gt; = .718). Nonruptured injuries (n = 352) had a significantly shorter RTP of 14.9 days versus rupture injuries with an RTP of 229 days (&lt;i&gt;P&lt;/i&gt; &lt; .001). Player age was significantly associated with RTP time, with younger players (≤26 years) exhibiting prolonged RTP durations (303.56 ± 112.97 days) compared to older players (&gt;26 years) (168.09 ± 99.66 days; &lt;i&gt;P&lt;/i&gt; = .017). There was no difference in RTP with field type (artificial turf vs grass, &lt;i&gt;P&lt;/i&gt; = .59). Reinjury rates increased over time but were not statistically significant (&lt;i&gt;P&lt;/i&gt; = .77). Following multivariate analysis, injury type was the only statistically significant factor affecting RTP duration, with ruptured Achilles injuries associated with significantly increased time missed compared to nonrupture injuries (95% CI, 171.15-264.11 days; &lt;i&gt;P&lt;/i&gt; &lt; .001).
