Background: Knot tying is a crucial component of successful arthroscopic shoulder surgery. It is currently unknown whether sliding or nonsliding techniques result in superior clinical outcomes. Purpose: To assess the clinical outcomes of arthroscopic sliding knot (SK)– versus nonsliding knot (NSK)–tying techniques during arthroscopic shoulder surgery, including rotator cuff repair, Bankart repair, and superior labral anterior-posterior (SLAP) repair. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic search of the PubMed, Embase, and Cochrane Library databases was performed using PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. All English-language literature published between 2000 and 2018 reporting clinical outcomes utilizing SK- or NSK-tying techniques during rotator cuff repair, Bankart repair, and SLAP repair with a minimum 24-month follow-up was reviewed by 2 independent reviewers. Information on type of surgery, knot used, failure rate, patient satisfaction, and patient-reported outcomes was collected. Patient-reported outcome measures included the Constant-Murley score, Rowe score, and visual analog scale for pain. Study quality was evaluated using the modified Coleman Methodology Score. Results: Overall, 9 studies (6 level 3 and 3 level 4) with a total of 671 patients (mean age, 52.8 years [range, 16-86 years]; 65.7% male; 206 SK and 465 NSK) were included. There were 4 studies that reported on Bankart repair in 148 patients (63 SK and 85 NSK), 3 on SLAP repair in 59 patients (59 SK), and 2 on rotator cuff repair in 464 patients (84 SK and 380 NSK). Also, 6 studies compared knot-tying with knotless techniques (3 Bankart repair studies and 3 SLAP repair studies), while the studies reporting the outcomes of SLAP repair evaluated SK-tying techniques only. The failure rate for Bankart repair was 3.2% (2/63) for SKs and 4.7% (4/85) for NSKs. The failure rate for rotator cuff repair was 2.4% (2/84) for SKs and 6.3% (24/380) for NSKs. The failure rate for SLAP repair was 11.9% (7/59). Because of inconsistencies in outcomes and procedures, no quantitative analysis was possible. The mean modified Coleman Methodology Score for all studies was 65.1 ± 8.77, indicating adequate methodology. Conclusion: The literature on clinical outcomes using SKs or NSKs for shoulder procedures is limited to level 4 evidence. Future studies should be prospective and focus on comparing the use of SKs and NSKs for shoulder procedures to elucidate which arthroscopic knot results in superior clinical outcomes.

Objectives: To examine the preoperative and postoperative performance of PROMIS Upper Extremity 2.0 across various orthopedic procedures for the upper extremity. Secondarily, to define susceptibility to pre- and post-operative floor and ceiling effects. Methods: Retrospective analysis of prospectively collected patient-reported outcome (PRO) data was conducted utilizing an electronic outcome registry for procedures between May 2017 and August 2018. Current procedural terminology (CPT) codes were utilized to examine cohorts for various upper extremity orthopedic procedures including Bankart repair and arthroscopic rotator cuff repair (ARCR). Shapiro-Wilks normality testing was used to assess score distributions for normalcy; given non-normal score distributions, Spearman correlation coefficients were calculated for preoperative patient-reported outcome (PRO) scores. Absolute floor and ceiling effects were calculated for each time point based on CPT code. Results: A total of 488 patients were included across Bankart repair (n=109, 29.3 + 12.5 years) and ARCR (n=379, 57.5 + 9.5 years) cohorts. In the Bankart repair cohort, PROMIS PI demonstrate strong correlations with ASES (r=-0.63), Constant (r=-0.75), PROMIS UE (r=-0.75), and the VR6D (r=-0.61). PROMIS Depression (r=0.23 vs. 0.17), SF12 MCS (r=0.34 vs. 0.11), and VR12 MCS (r=0.44 vs. 0.15) exhibited poor correlations with PROMIS PI and UE, respectively. In the ARCR cohort, PROMIS PI scores demonstrated a good correlation with PROMIS UE (r=0.61). Constant (r=0.58 vs. 0.67), VR12 PCS (r=0.58 vs. 0.47), and VR6D (r=0.67 vs. 0.53) exhibited good correlations with both PROMIS PI and UE measures, respectively. No significant absolute floor or ceiling effects were observed for the PROMIS instruments except PROMIS Depression; an absolute floor was noted for both Bankart (n=12, 30%) and ARCR (n=38, 14.7%) groups. Conclusions: PROMIS PI and UE instruments perform comparably to legacy outcome instruments in patients receiving Bankart repair, as well as those receiving ARCR. Furthermore, in both populations, the PROMIS Depression instrument exhibits absolute floor effects, whereas PROMIS PI and UE instruments fail to demonstrate any absolute floor or ceiling effects.

Electromyography (EMG) is a research tool used in gait analysis, muscle coordination evaluation, clinical evaluation and sports techniques. Electromyography can provide an insight into neural adaptations, cross education effects, bilateral contraction deficiencies, and antagonist activity in exercise-related movements. While there are clear benefits to using EMG in exercise-related professions, accessibility, cost, and difficulty interpreting the data limit its use in strength and clinical settings. We propose a practical EMG assessment using the isometric squat to identify compensatory activation patterns and report early observations. Ten healthy participants were recruited. Participants performed a 2-min isometric handgrip protocol and an isometric squat protocol. The isometric handgrip was used to identify the expected EMG amplitude response solely due to fatigue. There was a significant increase in EMG amplitude after 2 min (p < 0.05), with the relative increase of 95% CI (1.4%; 27.4%). This indicates the relative increase in EMG amplitude expected if the only influence was fatigue in the 2-min protocol. In the isometric squat protocol, we identified a number of different muscle activation compensation strategies with relative EMG amplitude increases outside of this bandwidth. One subject demonstrated a quadricep compensation strategy with a 188% increase in activation, while reducing activation in both the hamstrings and lower back by 12%. Exercise professionals can use this information to design exercise programs specifically targeting the unloaded muscles during the isometric squat.

Contralateral Effects

Neuromuscular electrostimulation (NMES) has been used mainly as a method to promote muscle strength, but its effects on improving blood flow are less well known. The aim of this study is to deepen the knowledge about the local and contralateral effects of the application of symmetric biphasic square currents on skin temperature (Tsk). An experimental pilot study was developed with a single study group consisting of 45 healthy subjects. Thermographic evaluations were recorded following the application of NMES to the anterior region of the thigh. The results showed an increase in the maximal Tsk of 0.67% in the anterior region of the thigh where the NMES was applied (p < 0.001) and an increase of 0.54% (p < 0.01) due to cross-education effects, which was higher when the NMES was applied on the dominant side (0.79%; p < 0.01). The duration of the effect was 20 min in the dominant leg and 10 min in the nondominant one. The application of a symmetrical biphasic current (8 Hz and 400 μs) creates an increase in the maximal Tsk at the local level. A temperature cross-education effect is produced, which is greater when the NMES is applied on the dominant side. This could be a useful noninvasive measurement tool in NMES treatments.
