Is biceps tenodesis necessary when performing arthroscopic rotator cuff repair in patients older than 55 years?

INTRODUCTION: In patients with arthroscopic rotator cuff repair, tenotomy and tenodesis are the most performed surgical procedures for the biceps long head (BLH) pathologies. Controversy continues as to which surgical procedure provides better results. This study aimed to compare the clinical outcomes of tenotomy and tenodesis applied to the biceps long head in patients who underwent arthroscopic rotator cuff repair. MATERIALS AND METHODS: In our study, the clinical results of 706 patients who underwent arthroscopic rotator cuff repair with tenotomy or tenodesis on the long biceps head were evaluated retrospectively. Rotator cuff repair patients were divided into two groups as single-row and double-row repair patients. The clinical results of patients who underwent tenotomy and tenodesis in single-row (n = 383) and double-row (n = 323) repair groups were compared. The clinical outcomes of the patients who underwent tenotomy and tenodesis without distinction between double/single-row repair were also compared. Preoperative and postoperative clinical evaluations of the patients were made with Constant Shoulder Score (CSS) and visual pain scale (VAS). The presence of the Popeye sign in the arm, tenderness in the bicipital groove, and cramping in the biceps muscle in the postoperative period was evaluated and compared among groups. Preoperative and postoperative clinical results of the patients were compared within the groups. RESULTS: A total of 706 patients with a mean age of 61.78 ± 20.94 years and a mean follow-up period of 29.15 ± 14.28 months were evaluated. The mean age of the tenodesis group (58.13 ± 8.47) was significantly lower than the tenotomy group (61.52 ± 22.58) (p < 0.05). The mean CSS and VAS mean postoperatively in the tenotomy group (n = 587) were 76.84 ± 12.74 and 2.29 ± 2.78. The postoperative mean CSS and VAS in the tenodesis group (n = 119) were 77.56 ± 11.23 and 2.64 ± 2.70. There was no statistically significant difference between the postoperative clinical scores of patients who underwent tenotomy and patients who underwent tenodesis (p > 0.05). There was no difference between the tenotomy and tenodesis groups regarding Popeye deformity (p = 0.980). Bicipital groove tenderness and cramping in the biceps muscle were significantly higher in the tenodesis group (p < 0.001, < 0.001). Tenodesis was performed in 68, and tenotomy was performed in 315 out of 383 patients who underwent single-row rotator cuff repair. Tenodesis was performed in 51, and tenotomy was performed in 272 of 334 patients who underwent double-row rotator cuff repair. When singe versus double-row groups was compared, there was no significant difference in VAS, CSS, Popeye sing, bicipital groove tenderness, or biceps muscle cramping. When tenotomy versus tenodesis was compared within single- and double-row repair groups, there was no significant difference in VAS or CSS. There was no difference between the tenotomy and tenodesis groups regarding Popeye deformity, but bicipital groove tenderness and muscle cramping were more in tenodesis groups regardless of the repair rows. CONCLUSIONS: The effect of tenodesis versus tenotomy for BHL pathologies in patients who underwent arthroscopic rotator cuff repair was not significant for clinical scores, but bicipital groove tenderness and biceps muscle cramping were significantly higher in the tenodesis group.

Effect of Soft Tissue Interposition and Postoperative Suspensory Cortical Button Migration on Functional Outcomes and Ligamentization After Single-Bundle ACL Reconstruction.

Background: Soft tissue interposition between a suspensory cortical button and the lateral femoral condyle is the most common cause of postoperative suspensory cortical button migration in patients undergoing anterior cruciate ligament reconstruction (ACLR). Purpose: To investigate the effects of soft tissue interposition and suspensory cortical button migration after ACLR on functional outcomes and graft ligamentization. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 249 patients who underwent single-bundle ACLR with hamstring tendon autografts. To measure soft tissue imposition, the patients were divided into 2 groups: those in whom the suspensory cortical button was in contact with (group 1) or at least 1 mm away from (group 2) the lateral femoral condyle on 1-day postoperative radiographs. To measure suspensory cortical button migration, the patients in group 2 were further divided into 2 subgroups: those with button migration (group M) and those without migration (group non-M) as observed on 12-month postoperative radiographs. Ligamentization was evaluated according to Howell classification (grades 1-4) on 12-month follow-up magnetic resonance imaging scans. Also recorded were preoperative and 24-month postoperative Lysholm and Tegner scores and 24-month postoperative arthrometer measurements for anterior knee laxity. Results: There was no significant difference between groups 1 and 2 or between groups M and non-M in terms of demographic characteristics or additional intra-articular pathologies detected intraoperatively. Normal anterior laxity (<3 mm) was detected in 83.7% of the patients postoperatively, and all patients showed statistically significant pre- to postoperative improvement on the Tegner (from 4.1 to 4.3) and Lysholm (from 44.0 to 89.2) scores (P < .05 for both). No significant difference in postoperative functional results or graft ligamentization was found between either the soft tissue interposition groups (groups 1 and 2) or the suspensory cortical button migration groups (groups M and non-M). Conclusion: Differences between patients in soft tissue interposition and suspensory cortical button migration did not significantly affect postoperative clinical or functional outcomes or graft ligamentization after single-bundle ACLR.

Evaluation of the Reliability and Quality of Information in Carpal Tunnel Syndrome Shared on YouTube.

Purpose Most of the internet users search online on YouTube for their health problems and the treatments. The purpose of this study is to evaluate the quality and the reliability of the videos on YouTube for Carpal tunnel syndrome (CTS). Methods The search was made by typing the keywords "Carpal tunnel syndrome" and/or "CTS" into the YouTube search engine, the first 50 videos on the first three pages of YouTube were evaluated. Of these videos, title, duration, number of views, days since uploaded, view ratio (view per day), number of likes, number of dislikes, video power index (VPI), video source, and video content data were recorded. The Journal of the American Medical Association (JAMA) benchmark criteria were used to evaluate the reliability of videos, where the Global Quality Score (GQS) and Carpal tunnel syndrome-specific score (CTS-SS) were used to evaluate the quality of the videos. Results The mean duration of the videos was 364.12 seconds (min 57, max 1,638) and the total duration of videos was 18,206 seconds. The mean number of views was 140,916.1 (min 10,543, max 1,271,040) and total number of views was 7,045,804. The mean JAMA score was 1.8 (min 1, max 4), the mean GQS was 2.72 (min 1, max 5), and the mean CTS-SS was 4.74 (min 1, max 14). There was no significant effect of video content on VPI, JAMA, GQS, or CTS-SS ( p >0.05). The JAMA, GQS, CT-SS scores of the videos from physicians and academic sources were significantly higher compared with other sources ( p <0.05). Conclusion YouTube is one of the most frequently used resource for patients to get information about their diagnosis and treatment methods and it consists of videos with low reliability and quality for CTS. We believe that the creation of an internet-based information resource, which the patients can refer to is one of the current social responsibilities of the physicians and the academicians. Level of Evidence This is a Level V study.

Pre-Participation Screening of Athletes: Primary Health Care Physicians' Knowledge, Experience, and Approach in Turkey.

Pre-participation screening (PPS) is crucial for assessing the competitive athletes since their risk of sudden death is higher than non-athletes. In Turkey, PPS is performed at the primary health care setting by primary care physicians (PCPs) who are family medicine specialists (FMSs) or general practitioners (GPs). Although there are national guidelines, there is no legal regulation for this process. This study aims to evaluate PCPs' knowledge, experience, and approach about PPS. We prepared an online survey for PCPs and used non-probabilistic sampling. PPS attitudes and practices were analyzed and compared according to factors such as experience, education, and being GP or FMS. Of the 214 PCPs included in the study, 39.3% were female. The mean age was 44.9 years (SD:8.88). The average work experience was 7.9 years. Most participants were aware of their authorization to perform PPS (89.7%) and had previously prepared it (90.2%). However, 6.5% of them felt confident in performing PPS. Only 13.1% were aware of the guidelines. Almost 25% of the participants stated being informed about the subject at some part of their career, but this did not affect the confidence or referral decisions. In addition to medical history and physical examination, further testing was considered necessary by 96.3% of the participants. Significantly more tests were ordered by GPs than FMSs (p=0.026 and p=0.011, respectively). The accurate referral decision ratio was 59.3%, without difference between FMSs and GPs (p=0.216). We found that awareness of the guidelines was low among PCPs who lack confidence in PPS. These factors collectively increased the tendency for unnecessary further testing and referral. Therefore, the PPS implementation into medical school and residency curriculums and national legal regulation for the process is a necessity in Turkey.

Optimal location for eliciting the tibial H-reflex and motor response.

INTRODUCTION: Although there are numerous protocols to adjust the amplitude of the Hoffmann reflex (H-reflex) relative to the size of the direct motor response (M-response), the optimal stimulating location has not been described. We sought to determine the optimal positioning of the stimulating cathode when evoking the tibial nerve H-reflex and M-response. METHODS: A small cathode was placed on defined points in the popliteal fossa while an anode was fixed on the patella. The tibial nerve was stimulated electrically, and the response of the soleus muscle was recorded using intramuscular and surface electromyography. RESULTS: We found that more-lateral points along a line drawn across the popliteal fossa were the best locations to obtain only the M-response, whereas stimulating the midpoint was optimal for obtaining only the H-reflex. DISCUSSION: By using specified locations for electrical stimulation to evoke H-reflex and M-response, the functionality of the tibial nerve can be assessed. Muscle Nerve 58:828-833, 2018.
