OBJECTIVE: The aim of the present study is to provide a comprehensive review on the surgical outcomes following arthroscopic treatments of partial-thickness rotator cuff tears (PT-RCTs) and to compare the postoperative American Shoulder and Elbow Surgeons (ASES) score following in situ transtendon repair and tear completion, followed by repair.
METHODS: Medline, EMBASE, Scopus, CINAHL and CENTRAL bibliographic databases were searched. Papers including patients with PT-RCTs of any grade who underwent treatment using debridement, in situ transtendon repair, tear completion and repair or bioinductive collagen implants were reviewed. Primary PT-RCTs were the sole indication for surgery. Primary postoperative outcomes assessed included the ASES score, the Absolute Constant-Murley score, the Simple Shoulder Test, the Visual Analogue Scale, the University of California-Los Angeles Shoulder Scale, the Western Ontario Rotator Cuff Score, range of motion, complications and revisions. A meta-analysis of comparative studies compared the postoperative ASES score between patients treated with in situ transtendon repair versus tear completion repair.
RESULTS: Twenty-eight studies were included. The ASES score was reported by four comparative studies with contrasting results. The heterogeneity was high (I2 = 86%), and effect sizes ranged from -0.49 in favour of the tear completion and repair technique to an effect size of +1.07 favouring in situ transtendon repair. The overall effect size of 0.02 suggests an equivalence between the two techniques in terms of the ASES score. Two studies with a total sample size of 111 patients reported on debridement, and four studies with a total sample size of 155 patients reported on bioinductive collagen implants.
CONCLUSIONS: Debridement alone is suitable for Ellman grades I-II PT-RCTs. In situ transtendon and tear completion repair techniques yield similar postoperative outcomes. Bioinductive collagen implants hold promise but lack long-term efficacy data. High-quality comparative studies are needed to determine the best treatment for PT-RCTs.
METHODS: Level IV.

BACKGROUND: In ACL reconstruction, it is desirable to assess preoperatively whether a sufficient graft diameter can be achieved with the planned tendon graft. The present study investigated the effect of the location of the cross-sectional area (CSA) measurement of the hamstring tendons in preoperative MRI on the correlation of the CSA with the intraoperative graft diameter. In addition, we analyzed whether the measurement results of examiners with different skill levels were comparable.
METHODS: A total of 32 subjects undergoing a single bundle ACL reconstruction using an autologous ipsilateral quadrupled hamstring graft (STGT) were included. The CSA of the semitendinosus and gracilis tendon was determined in preoperative MRI on six defined levels by three examiners. The intraclass correlation coefficient between the measurements of these observers was determined. The correlation between the sum of the CSA of both tendons (CSA STGT) and the graft diameter was investigated.
RESULTS: The interrater reliability was excellent on most of the investigated levels. A significant correlation between CSA STGT and the graft diameter was seen on all levels. The strongest correlation was found on the level 10 mm above the joint line.
CONCLUSIONS: The measurement of the CSA STGT in the preoperative MRI 10 mm above the joint line enabled a good assessment of the achievable graft diameter in ACL reconstruction, independent of the examiners\' training level.

Background and Objectives: Lateral ankle injuries are commonly encountered injuries, and the open modified Broström operation (OMBO) is the primary treatment option. Recently, an arthroscopic modification of the Broström operation (AMBO) was developed; many studies have shown that there are no significant differences in clinical and radiological outcomes between the two surgical methods. However, no studies have been conducted comparing the two surgical methods in terms of return to play (RTP) time. This study assesses the time to RTP and the functional clinical outcomes. Materials and Methods: Sixty patients were enrolled from January 2012 to July 2014. They were segregated into two cohorts: the AMBO group comprised 30 patients, while the OMBO group comprised another 30 patients. Each participant underwent standardized treatment and rehabilitation regimens and RTP time was measured using seven questions that explored the times to return of painless walking, running, jumping, squatting, climbing stairs, and rising up on the heels and toes. We compared the time intervals from the onset of instability to the date of surgery. Clinical outcomes were evaluated before the surgery, 6 weeks after surgery, and 6 months after surgery. The assessments included the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, the pain visual analog scale (VAS) score, subjective satisfaction with rehabilitation, and activity level. Results: In terms of RTP, AMBO was associated with a shorter interval to walking without pain (7.07 ± 2.96 weeks) relative to OMBO (11.03 ± 8.58 weeks). No disparities were observed in the time to return to play (RTP) between OMBO and AMBO. While there were no discrepancies in the 6-month postoperative AOFAS or VAS scores, the 6-week postoperative VAS score was notably lower in the AMBO group compared to the OMBO group. AMBO provided a faster RTP in terms of two of the seven questions in a group exhibiting high-level physical activity. The rate of subjective satisfaction with rehabilitation was higher for AMBO than for OMBO. Conclusions: Aside from walking, the duration to return to play and the clinical outcomes were similar between AMBO and OMBO treatments for lateral ankle instability. AMBO is a good treatment option and should be carefully considered for athletes with lateral ankle instability. AMBO demonstrated positive outcomes in a group with higher activity levels compared to others, particularly in terms of time to RTP, subjective satisfaction, and postoperative pain.

OBJECTIVE: To determine the effect of bone marrow stimulation (BMS) on retear rates, functional outcomes, and complication rates in patients who underwent arthroscopic rotator cuff repair (RCR) through a meta-analysis of randomized controlled trials.
METHODS: PubMed, EMBASE, Web of Science, and The Cochrane Library were searched on March 25, 2023. Two evaluators independently screened the literature, extracted data, and assessed the methodologic quality of the enrolled studies. Meta-analysis was conducted using RevMan software, version 5.4.
RESULTS: A total of 7 randomized controlled trials with 638 patients were included. The evaluation of rotator cuff tendon integrity was conducted using distinct imaging modalities. Specifically, 259 patients underwent magnetic resonance imaging whereas 208 patients underwent ultrasound. Additionally, a subset of 95 patients underwent either of these modalities; however, the precise distribution between these 2 modalities was not explicitly delineated. Compared with RCR alone, RCR combined with BMS provided similar retear rates (P = .51, I2 = 46%), Constant-Murley scores (P = .14, I2 = 0%), American Shoulder and Elbow Surgeons (standardized shoulder assessment form) scores (P = .56, I2 = 0%), Western Ontario Rotator Cuff Index scores (P = .20, I2 = 0%), visual analog scale scores (P = .19, I2 = 0%), forward flexion (P = .18, I2 = 0%), external rotation (P = .62, I2 = 0%), severe complication rates (P = .56, I2 = 0%), and mild complication rates (P = .10, I2 = 0%).
CONCLUSIONS: Compared with the outcomes observed after isolated arthroscopic RCR, arthroscopic RCR with BMS showed comparable results in terms of retear rate, functional outcomes, and incidence of complications.
METHODS: Level II, meta-analysis of Level I and II studies.

UNASSIGNED: Posterior cruciate ligament (PCL) tears in young children are rare and optimal treatment is poorly described. Diagnosis may prove challenging as young children may not be able to verbalize a complete history of injury, may be difficult to examine, and plane film radiographs often appear within normal limits. Surgical treatment carries a risk of physeal arrest, but non-operative treatment may lead to recurrent instability and pain.
UNASSIGNED: We present a case report of a fouryear- old child with a PCL avulsion off the femoral insertion who received an open reduction and internal fixation (ORIF) with combined arthroscopic synovial debridement. We performed a literature review which compared the mechanism, location, concomitant injuries, work up and management of PCL injuries in children under the age of ten compared to adolescents and adults.
UNASSIGNED: Nineteen months following surgery, physical examination revealed full knee range of motion and return to baseline function. Imaging studies confirmed there was no evidence of physeal arrest.
UNASSIGNED: ORIF with arthroscopy can be an effective method to treat PCL avulsions in children under the age of 10 years. This is similar to other case reports which reported positive outcomes with ORIF in this population. Large studies are needed to best understand optimal treatment modalities for PCL injuries in very young children. Level of Evidence: IV.

UNASSIGNED: The National Institutes of Health (NIH) and American Medical Association (AMA) recommend that online health information be written at a maximum 6th grade reading level. The aim was to evaluate online resources regarding shoulder arthroscopy utilizing measures of readability, understandability, and actionability, using syntax reading grade level and the Patient Education Materials Assessment Tool (PEMAT-P).
UNASSIGNED: An online Google™ search utilizing \"shoulder arthroscopy\" was performed. From the top 50 results, websites directed at educating patients were included. News and scientific articles, audiovisual materials, industry websites, and unrelated materials were excluded. Readability was calculated using objective algorithms: Flesch-Kincaid Grade-Level (FKGL), Simple Measure of Gobbledygook (SMOG) grade, Coleman-Liau Index (CLI), and Gunning-Fog Index (GFI). The PEMAT-P was used to assess understandability and actionability, with a 70% score threshold. Scores were compared across academic institutions, private practices, and commercial health publishers. The correlation between search rank and readability, understandability, and actionability was calculated.
UNASSIGNED: Two independent searches yielded 53 websites, with 44 (83.02%) meeting inclusion criteria. No mean readability score performed below a 10th grade reading level. Only one website scored at or below 6th grade reading level. Mean understandability and actionability scores were 63.02%±12.09 and 29.77%±20.63, neither of which met the PEMAT threshold. Twelve (27.27%) websites met the understandability threshold, while none met the actionability threshold. Institution categories scored similarly in understandability (61.71%, 62.68%, 63.67%) among academic, private practice, and commercial health publishers respectively (p=0.9536). No readability or PEMAT score correlated with search rank.
UNASSIGNED: Online shoulder arthroscopy patient education materials score poorly in readability, understandability, and actionability. One website scored at the NIH and AMA recommended reading level, and 27.27% of websites scored above the 70% PEMAT score for understandability. None met the actionability threshold. Future efforts should improve online resources to optimize patient education and facilitate informed decision-making. Level of Evidence: IV.

OBJECTIVE: The aim of this study was to investigate whether multimodal analgesia can decrease postoperative opioid usage in patients undergoing shoulder arthroscopy.
METHODS: Patients diagnosed with subacromial impingement syndrome who underwent acromioplasty at our institution between October 2022 and November 2023 were retrospectively analyzed. Patients were divided into an observation group and a control group based on postoperative pain management methods. The control group received intravenous self-controlled electronic analgesia (sufentanil injection 1 μg/kg + butorphanol injection 4 mg + 0.9% NaCl injection to 100 mL), while the observation group received multimodal analgesia (ropivacaine subacromial pump 3 mL/h, combined with oral celecoxib and acetaminophen). Visual Analog Scale (VAS) scores were recorded preoperatively and at various postoperative time points, and opioid usage, length of hospital stay, and analgesia-related complications within 1 week postoperatively were compared between groups. The 36-item Short Form Health Survey (SF-36) scores and the Constant-Murley score (CMS), were also assessed 1 day and 1 week after treatment.
RESULTS: One hundred thirty-two patients were included in the study, 66 in the observation group and 66 in the control group. In the control group, there were 46 males and 20 females, with a mean age of 55.47 ± 11.42 years and in the observation group 44 males and 22 females, with a mean age of 56.13 ± 12.19 years The observation group consistently reported significantly lower pain intensity compared to the control group at 8 h (T1), 24 (T2), and 48 h (T3) after surgery (p < 0.05). Additionally, the observation group exhibited significantly lower opioid usage and complication rates compared to the control group (p < 0.05). SF-36 scores and CMS scores were significantly higher in the observation group 1 week after treatment compared to the control group (p < 0.05).
CONCLUSIONS: Following shoulder arthroscopy, multimodal analgesia effectively reduces opioid consumption, lowers complication rates, and provides effective short-term pain relief. This approach carries significant implications for improving patient outcomes.

UNASSIGNED: To compare the short-term effectiveness of suture hook suture via double posteromedial approaches and Fast-Fix total internal suture in treatment of Ramp lesions.
UNASSIGNED: A clinical data of 56 patients with anterior cruciate ligament rupture combined with Ramp lesions, who met the selection criteria and admitted between December 2021 and February 2023, was retrospectively analyzed. The Ramp lesions were sutured using suture hook via double posteromedial approaches under arthroscopy in 28 cases (group A) and treated with Fast-Fix total internal suture under arthroscopy in 28 cases (group B). There was no significant difference in age, gender, cause of injury, type of injury, time from injury to operation, side of injury, body mass index, and preoperative Lysholm score, visual analogue scale (VAS) score, and Tegner score between the two groups ( P>0.05). The patients were followed up regularly after operation, and the clinical and imaging healing of the Ramp lesion was evaluated according to the Barrett clinical healing standard and the MRI evaluation standard. Lysholm score, VAS score, and Tegner score were used to evaluate the function and pain degree of knee joint, and the results were compared with those before operation.
UNASSIGNED: The incisions of the two groups healed by first intention. All patients were followed up 12-18 months (mean, 14.9 months). Postoperative McMurray tests were negative in both groups. The clinical healing rates of group A and group B were 71.4% (20/28) and 64.3% (18/28) at 6 months after operation, and 92.9% (26/28) and 82.1% (23/28) at 12 months after operation, respectively. The differences between the two groups was not significant ( χ 2=0.327, P=0.567; χ 2=0.469, P=0.225). There was no significant difference in Lysholm score, VAS score, and Tegner score between the two groups at each time point after operation ( P>0.05). The postoperative scores in the two groups significantly improved when compared with those before operation, and the scores at 12 months after operation further improved when compared with those at 6 months after operation, showing significant differences between the different time points in the two groups ( P<0.05). At last follow-up, MRI examination of the knee joint showed that there were 26 (92.9%), 2 (7.1%), and 0 (0) cases of complete healing, partial healing, and nonunion in the Ramp lesion of group A, and 25 (89.3%), 1 (3.6%), and 2 (7.1%) cases in group B, respectively. There was no significant difference between the two groups ( Z=-0.530, P=0.596).
UNASSIGNED: Suture hook suture via double posteromedial approaches and Fast-Fix total internal suture under arthroscopy are safe and reliable in the treatment of Ramp lesion, and the knee joint function significantly improves after operation.
