RESUMEN
PURPOSE: To prospectively compare pain intensity and patient-reported outcomes (PROs) after arthroscopic rotator cuff repair (ARCR) between patients who received ultrasound-guided suprascapular nerve block (SSNB) and axillary nerve block (ANB) as well as preincisional parecoxib and patients who received preincisional parecoxib only. METHODS: Sixty-one patients receiving ARCR between March 2020 and March 2021 were prospectively enrolled. They were randomly assigned to the peripheral nerve block group (group N, n = 30) or control group (group C, n = 31). Two patients in group C were excluded because of miscommunication. All patients were administered 40 mg of parecoxib intravenously prior to induction of anesthesia. SSNB and ANB were performed after general anesthesia in group N, whereas no nerve block was performed in group C. Pain intensity was compared before surgery, as well as immediately, 24 hours, and 2 weeks after surgery. PROs, including the Oxford Shoulder Score, University of California-Los Angeles shoulder score, and Single Assessment Numeric Evaluation score, were compared before and 6 months after surgery. RESULTS: The numerical rating scale (NRS) score for resting pain was significantly lower in group N (4.9 ± 3.1 vs 7.6 ± 2.5, P < .001) immediately after surgery, but no difference was noted 24 hours after surgery. The resting pain NRS score 2 weeks after surgery was significantly lower in group N (1.4 ± 1.6 vs 2.7 ± 2.7, P = .03), but the scores for movement-evoked pain and night pain were similar. All PROs significantly improved 6 months after surgery in both groups, but there was no difference between the 2 groups. CONCLUSIONS: The addition of preoperative ultrasound-guided SSNB and ANB to parecoxib offered better resting pain control immediately and 2 weeks after ARCR, but there was no benefit for PROs 6 months after surgery. LEVEL OF EVIDENCE: Level II, prospective randomized controlled trial.
RESUMEN
There is currently no consensus on the optimal placement of the tibial tunnel for double-bundle posterior cruciate ligament (PCL) reconstruction. The purpose of this study was to compare the clinical and radiologic outcomes of double-bundle PCL reconstruction utilizing anatomic versus low tibial tunnels. We conducted a retrospective cohort study involving patients who underwent double-bundle PCL reconstruction between Jan 2019 and Jan 2022, with a minimum follow-up of 2 years (n = 36). Based on the tibial tunnel position on postoperative computed tomography, patients were categorized into two groups: anatomic placement (group A; n = 18) and low tunnel placement (group L; n = 18). We compared the range of motion, stability test, complications, and side-to-side differences in tibial posterior translation using kneeling stress radiography between the two groups. There were no significant differences between the groups regarding clinical outcomes or complication rates. No significant differences in the posterior drawer test and side-to-side difference on kneeling stress radiography (2.5 ± 1.2 mm in group A vs. 3.7 ± 2.0 mm in group L; p = 0.346). In conclusion, the main findings of this study indicate that both anatomic tunnel and low tibial tunnel placements in double-bundle PCL reconstruction demonstrated comparable and satisfactory clinical and radiologic outcomes, with similar overall complication rates at the 2-year follow-up.

BACKGROUND: Soft tissue release (STR) is an established treatment for spastic hip displacement, but recurrence of hip displacement is not uncommon. This study aims to (1) evaluate the recurrence of hip displacement after STR, (2) define associated factors of recurrence, and (3) elucidate the effects of guided growth on hip displacement recurrence. METHODS: The study subjects included 66 individuals with spastic cerebral palsy treated by STR with or without guided growth for hip displacement. The treatment goal was the maintenance of migration percentage (MP) to <40%. Recurrence was defined by a rebound of the MP by 5% or more after the first postoperative year. Children with recurrence were compared with those without recurrence using the Mann-Whitney U test and the χ 2 test. The risk factors for recurrence were evaluated using multiple logistic regression analysis. RESULTS: Nineteen individuals (29%) had a recurrence of hip displacement after the first postoperative year. They sustained a 2-fold increase in the rate of treatment failure ( P < 0.001) and reoperation ( P = 0.04). Age, sex, motor function, and preoperative radiographic parameters were comparable between individuals with and without recurrence. The use of guided growth was associated with less risk of recurrence than without (5% and 39%, respectively, odds ratio = 0.01 to 0.45, respectively) despite the similar risk of failure (35% and 48%, respectively, odds ratio = 0.15 to 4.82). CONCLUSIONS: Recurrence of the MP >5% after the first postoperative year is an important early indicator for failure to control MP to <40% and reoperation. Guided growth not only decreases coxa valga but also reduces the risk of recurrent hip displacement after STR. LEVEL OF EVIDENCE: Level III; case-control study.

The patellofemoral joint involves a combination of bony structures and soft tissues to maintain stability. Patella instability is a disabling condition, and the cause is multifactorial. The main risk factors include patella alta, trochlea dysplasia, excessive tibial tuberosity to trochlea grove (TT-TG) distance, and excessive lateral patella tilt. In this case report, we highlight the thinking process of diagnosis and method for selecting the optimal treatment in accordance with the guidelines by Dejour et al. when we are presented with a patient with patella instability. A 20-year-old Asian woman without underlying medical conditions, presented with recurrent (>3 episodes) right patella dislocation for 7 years. Investigations revealed a type D trochlea dysplasia, increased TT-TG distance, and excessive lateral tilt angle. She underwent trochlea sulcus deepening, sulcus lateralization and lateral facet elevation, lateral retinacular release, and medial quadriceps tendon-femoral ligament (MQTFL) reconstruction. Due to the complexity behind the anatomy and biomechanics of patella instability, an easy-to-follow treatment algorithm is essential for the treating surgeon to provide effective and efficient treatment. MQTFL reconstruction is recommended for recurrent patella dislocation due to satisfactory clinical and patient reported outcomes and a reduced risk of iatrogenic patella fracture. Controversies for surgical indication in lateral retinacular release, and whether the sulcus angle is an accurate parameter for diagnosis of trochlea dysplasia, remain, and further research is required.

Introduction: Concomitant nerve injuries with musculoskeletal injuries present a challenging problem. The goals of nerve reconstruction for the shoulder include shoulder abduction and external rotation. When patients fail to achieve acceptable shoulder external rotation and shoulder abduction, tendon transfers such as trapezius transfer offer a reliable option in the subsequent stage. Case Presentation: A 32-year-old male presented with weak external rotation in his left shoulder, after previous axillary nerve reconstruction. He received the ipsilateral lower trapezius transfer with the aim of improving the external rotation. Discussion: The lower trapezius restores a better joint reaction force in both the compressive-distractive and anterior-posterior balancing and provides a centering force through the restoration of the anterior-posterior force couple. Conclusion: We believe that the ipsilateral lower trapezius transfer to the infraspinatus is a good outcome and is effective in improving overall shoulder stability and the shoulder external rotation moment arm or at least maintaining in neutral position with the arm fully adducted in patients with post axillary nerve injuries post unsatisfactory nerve reconstruction to increase the quality of life and activities of daily living.

BACKGROUND: Guided growth at the proximal femur using one transphyseal screw corrects coxa valga and improves hip displacement in cerebral palsy. This study aimed to validate the effects of adding guided growth (GG) to soft tissue release (STR), in terms of decreasing the migration percentage (MP), compared to those with soft tissue alone. METHODS: This retrospective study comprised patients with cerebral palsy who underwent soft tissue release alone (Group STR) or soft tissue release plus guided growth (Group GG) for hip displacement (mean age, 8.1 years; mean follow-up, 4.9 years). Difference in the MP and rate of controlling MP <40% at 2 years postoperatively and rate of revision surgeries at 5 years postoperatively were compared between the groups. RESULTS: The two groups were comparable in age, side, and gross motor function level, but Group GG (n = 24) had more severe hip displacement preoperatively than did Group STR (n = 64). Group GG had a significantly greater 2-year decrease in the MP (-14.8% vs. -11.8%, p < 0.05) than did Group STR. Among patients with a pre-operative MP >50%, the rate of MP <40% was greater in Group GG (73%) than in Group STR (41%). Revision surgeries, mainly repeated guided growth and soft tissue release, were comparable between the groups. CONCLUSIONS: This is the first comparative study to support adding guided growth to soft tissue release, as it results in greater improvements in hip displacement than that with soft tissue release alone. Non-ambulatory patients or severe hip displacement with MP 50%-70% could benefit from this less aggressive surgery by controlling the MP under 40% without femoral osteotomy.

Arthroscopic capsular release allows direct visualization and release of inflamed tissues in refractory frozen shoulder. The reticular neural network in the long head of the biceps tendon (LHBT) and nerve endings of the transverse humeral ligament (THL) might be responsible for shoulder pain. We hypothesized that patients with painful refractory frozen shoulder benefited from pan-capsular release, THL release, and LHBT tenodesis. The LHBT tenodesis decreased the possibility of LHBT instability. The balance of the shoulder joint was maintained after such extensive release. From October 2013 to June 2019, patients with painful refractory frozen shoulder were enrolled consecutively at the same institute. All patients received arthroscopic pan-capsular, THL release, and suprapectoral LHBT tenodesis with a minimum of 2-year follow-up. Preoperative and postoperative shoulder range of motion (ROM), pain visual analog scale (PVAS), subjective shoulder value (SSV), constant score, LHBT score, acromio-humeral distance (AHD), and critical shoulder angle (CSA) were recorded. In total, 35 patients with an average age of 53.1 ± 9 years were enrolled. The average follow-up period was 24 ± 1.5 months. Forward elevation improved from 105.1° ± 17° to 147° ± 12° (p < 0.001), external rotation improved from 24.1° ± 13.3° to 50.9° ± 9.7° (p < 0.001), and internal rotation improved from L3 to T9 (p < 0.001), respectively, at final follow-up. PVAS improved from 7.3 ± 1.1 to 1.8 ± 0.6 (p < 0.001), constant score from 23.4 ± 11 to 80.7 ± 5.2 (p < 0.001), and SSV from 27.7 ± 10.5 to 77.4 ± 3.8, respectively, at follow-up. No differences were found in AHD and CSA after surgery (p = 0.316, and p = 0.895, respectively). Patients with painful refractory frozen shoulder benefited from pan-capsular and THL release. A radiographically balanced shoulder joint was maintained even after such extensive release.

A 16-year-old right-handed male pitcher had a first-time right anterior shoulder dislocation during a baseball game. X-ray and MRI revealed no apparent glenoid bone loss or Hill-Sachs lesion, but an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion with mild posterolateral decompression of the humerus head. His instability severity index score (ISIS score) was 5 with an on-track lesion. He had an arthroscopic Bankart repair using two all-suture anchors and returned to pitching 6 months after the index surgery. However, he had an unstable sensation after 50 pitches during a game one year postoperatively. This time, he presented with a significant Hill-Sachs lesion and a recurrent APLSA lesion. His ISIS score was 6 with an on-tract lesion. During the arthroscopic examination, the previous suture was stable, while anterior capsuloligament tissues were dislodged from sutures, and a Hill-Sachs lesion was observed. This time, a revision arthroscopic Bankart repair and Remplissage procedure were done on him with four double-loaded soft tissue anchors. Pitchers often develop more external rotation in their throwing arm because of a repetitive stretch of the anterior shoulder capsule and ligaments during pitching. The decrease in external rotation after surgery may limit the pitching speed of the pitcher, making a return to play (RTP) more difficult. There is still a paucity of best evidence to revise a failed arthroscopic Bankart repair in the dominant arm of a pitcher. Arthroscopic Bankart repair and Remplissage procedure have gained increasing popularity because they can provide a stable shoulder without harvesting the coracoid. The Latarjet procedure provides a high RTP rate; however, we did not perform it in the revision surgery and decided to revise the Bankart lesion again on its own with a Remplissage procedure, even with his ISIS score being 6 before the revision surgery. A salvage Latarjet procedure is left as a bailout procedure.

Shoulder arthroscopy is a mature and widely used treatment to deal with various shoulder disorders. It enables faster recovery and decreases postoperative complications. However, some complications related to shoulder arthroscopy cannot be neglected because they could be life threatening. We presented three cases of various clinical manifestations of pneumothorax after shoulder arthroscopy. The first case was a 65-year-old female who underwent arthroscopic rotator cuff repair under general anesthesia and interscalene nerve block in the beach-chair position. The second case was a 58-year-old male undergoing arthroscopic rotator cuff repair and reduction in glenoid fracture under general anesthesia in the lateral decubitus position. The third case was a 62-year-old man receiving arthroscopic rotator cuff repair under general anesthesia in the lateral decubitus position. Each case's operation time was 90, 240, and 270 min. The pressure of the irrigation pumping system was 30, 50, and 70 mmHg, respectively. The second and third cases did not undergo interscalene nerve block. Although the incidence of pneumothorax following shoulder surgery and interscalene nerve block was only 0.2%, it is one of the most life-threatening complications following shoulder arthroscopy. In these cases, multifactorial factors, including patient positioning, interscalene nerve block, long surgical time, size of rotator cuff tears, and the pressure of the irrigation and suction system, can be attributed to the occurrence of pneumothorax. It is crucial to fully comprehend the diagnosis and management of pneumothorax to reduce the risk for patients receiving shoulder arthroscopy.

BACKGROUND: Compared to patients without Parkinson's disease (PD), patients with PD who underwent spinal surgeries were reported to have a relatively high complication rate. However, studies that analyze surgical risk factors for these patients are limited. METHODS: From October 2004 to April 2015, patients with PD who underwent spinal surgeries at our department were reviewed. Patients who underwent lumbar or thoracolumbar instrumented surgeries due to degeneration or deformity disease were included. Any reason for revision surgery was recorded. Risk factors including patients' factors, surgical factors, and lumbo-pelvic radiographic parameters were analyzed. Patients' factors included patients' underlying diseases, body mass index (BMI), osteoporotic status, and PD's severity using the modified Hoehn and Yahr staging scale. Surgical factors included surgical levels, extending to thoracic spine or not, corrective osteotomy, with anterior approach or not, and interbody device. Radiographic parameters included lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), coronal Cobb's angles, and score for spino-pelvic realignment achievement. RESULTS: A total of 66 patients were enrolled. The mean age at surgery was 69.0 years old. The mean follow-up time was 51.2 months. Twenty-six revision surgeries were required in 19 patients (29%). Risk factors for revision surgery included modified Hoehn and Yahr stage ≥3 (p < 0.001), cancer history (p = 0.024), osteoporosis (P = 0.012) and underwent corrective osteotomy (p = 0.035). According to binary logistic regression analysis, the modified Hoehn and Yahr stage ≥3 (p < 0.001) was the only independent risk factor. The Kaplan-Meier analysis revealed patients with long instrumentation (surgical levels > 3), T-spine instrumentation, and lower score of spino-pelvic realignment achievement tended to have earlier revision. CONCLUSION: For PD patients planning for elective thoracolumbar surgery, aggressive control status of PD before or after surgery is necessary to prevent surgical complications. Longer surgical levels and corrective osteotomy also tended to have earlier revision. A better score in spino-pelvic realignment achievement after surgery could reduce occurrence of revision.

BACKGROUND: Ultrasonographic structural abnormalities are regarded as one of the risk factors of elbow injuries. Elbow injuries are commonly associated with decreased shoulder/elbow range of motion (ROM). The purpose of this study is to determine the relationship between shoulder/elbow ROM and elbow ultrasonographic structural abnormalities in Taiwan high school baseball players. METHODS: A total of 533 Taiwan high school baseball players were enrolled. Physical examinations including measurements on shoulder/elbow ROM and elbow sonographic examinations were performed and recorded by professional physicians. The analyses were conducted in three subgroups according to their defensive position because the training programs were different. All players pooled, pitchers-only, and fielders-only, due to several demographic differences among these subgroups. In all the subgroups, univariate analyses were conducted separately for participants with and those without elbow ultrasonographic structural abnormalities, and then multivariate analyses were conducted to identify factors significantly related. The odds ratios (ORs) were used to estimate the risk of elbow ultrasonographic structural abnormalities. RESULTS: Demographic data showed that pitchers had taller body height (P < 0.001) and greater elbow flexion/extension ROM (P < 0.001). When all players were pooled, significant risk factors included started playing baseball at an younger age (OR = 1.202; 95% CI = 1.064-1.357; P = 0.003), longer experience of official baseball (OR = 1.154; 95% CI = 1.038-1.283; P = 0.008), lower total shoulder rotation angle (OR = 1.007; 95% CI = 1.000-1.014; P = 0.050), and less total elbow arm angle (OR = 1.052; 95% CI = 1.017-1.088; P = 0.003) For pitchers, significant risk factors included longer experience of official baseball (OR = 1.342; 95% CI = 1.098-1.640; P = 0.004), lower total shoulder rotation angle (OR = 1.016; 95% CI = 1.004-1.027; P = 0.006), and lower total elbow arm angle (OR = 1.075; 95% CI = 1.024-1.129; P = 0.004) (Table 5). There were no significant risk factors for elbow structural abnormalities in fielders. CONCLUSION: For Taiwan high school pitchers, longer official baseball experience, decreased shoulder total rotational angle, and decreased elbow total flexion/extension angle, were related to ultrasonographic structural abnormalities in elbows.
RESUMEN
BACKGROUND: The ulnar collateral ligament (UCL) is essential for elbow stability during pitching. In professional baseball, the fastball (FB) is the most commonly used pitch, making postrecovery FB performance after UCL reconstruction (UCLR) a crucial aspect to consider. HYPOTHESES: (1) Pitchers undergoing UCLR would show no significant changes in performance metrics compared with nonoperated pitchers with similar FB velocity and spin rate, and (2) no significant variance would be found in these metrics within the operated pitchers concerning their preinjury anthropometric characteristics and pitching performance metrics. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The study included 91 Major League Baseball (MLB) pitchers who underwent primary UCLR between January 1, 2015, and December 31, 2021. A matched 1:1 control group of MLB pitchers without UCLR injuries was established. Publicly available pitch metrics and anthropometric data were compared between the study and control groups. RESULTS: Disparities in several performance metrics emerged during the first postreturn year (PRY1), including FB use percentage (P = .029), fielder independent pitching (FIP) (P = .021), and standardized FB runs above average per 100 pitches (wFB/C) (P < .001). Subgroup analysis within the UCLR group revealed a negative correlation between presurgery mean FB velocity and its subsequent change (P < .001) and a positive correlation with changes in FIP (P = .025) from the index year to PRY1. A negative correlation was observed between FB use percentage in the index year and its change by PRY1 (P = .002). By the second postreturn year, no significant differences were found in these performance metrics. No factors were significantly related to prolonged recovery time. CONCLUSION: Although FB velocity and spin rate remained consistent, significant differences were observed in FB use percentage, FIP, and wFB/C in PRY1. However, by second postreturn year, these differences were no longer significant. No specific risk factors were identified concerning prolonged recovery time between pre-UCLR FB pitching metrics and the physical anthropometric data. These results suggest that although the short-term postsurgery period may affect more specialized pitching metrics, the basic pitching performance metrics, as hypothesized, remain largely unaffected by UCLR.

Background: There is limited research investigating the diagnostic strength of 3-dimensional computed tomography (3D-CT) and multidirectional CT arthrography (CTA) for femoroacetabular impingement (FAI) and related hip lesions. Purpose: To evaluate the diagnostic strength of combined 3D-CT and CTA in patients with FAI and related hip lesions by comparing it with hip arthroscopic surgery findings. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: This study included patients who were suspected of having FAI and related hip lesions and who underwent a combination of 3D-CT and CTA and subsequent hip arthroscopic surgery between December 2013 and December 2017. The CT and intraoperative arthroscopic findings were recorded and compared. The sensitivity, specificity, and accuracy of 3D-CT for FAI and those of CTA for related hip lesions were calculated. Results: A total of 114 patients with 114 hips were included in our study. There were 101 patients with positive findings and 13 patients with negative findings for FAI (including cam, pincer, and combined morphology) according to 3D-CT. The sensitivity, specificity, and accuracy of 3D-CT for FAI were 91.58%, 57.14%, and 89.47%, respectively. The sensitivity, specificity, and accuracy of CTA for labral tears were 94.64%, 100.00%, and 94.73%, respectively. For acetabular cartilage defects, the sensitivity, specificity, and accuracy of CTA were 60.71%, 91.37%, and 76.31%, respectively. For femoral cartilage defects, the sensitivity, specificity, and accuracy of CTA were 82.22%, 76.81%, and 78.94%, respectively. Conclusion: The study results indicated that 3D-CT was able to provide excellent accuracy for FAI compared with hip arthroscopic surgery findings. In addition, multidirectional CTA demonstrated promising diagnostic strength for hip lesions such as labral tears and chondral defects.
RESUMEN
INTRODUCTION: The best treatment for Rockwood type V acromioclavicular (AC) joint dislocation is unknown. HYPOTHESIS: Hook plate augmented with suture anchor (HA) may have different clinical and radiological results than hook plate alone (H), and arthroscopically assisted TightRope (TR) techniques in treating acute type V AC joint dislocations. MATERIAL AND METHODS: This retrospective study included 71 patients with acute type V AC joint dislocations between December 2010 and August 2018. Patients were categorized into three groups: H group (n=22), HA group (n=23) and TR group (n=26). We measured the coracoclavicular distance (CCD) differences and CCD ratio compared to uninjured side pre-operatively, immediately post-operatively, at 3-month and 2-year after operation. Clinical outcomes were assessed as well at the same time points. Loss of correction was determined by the CCD difference and ratio between surgical and uninjured sides. RESULTS: The mean age and follow-up period were 41.8±24.7 years and 30.2±4.3 months, respectively. No significant differences were found in the demographic data between the three groups. The HA group presented a trend of less overcorrection but without significance compared with the H group at immediately post-operation, 3-month, and 2-year follow-up. (CCD difference: -2.4mm vs. -3.7mm, -1.6mm vs. -1.8, and 0.2mm vs -1.9mm, CCD ratio: 67.7% vs. 40.9%, 79.3% vs. 70.1%, and 100.6% vs. 86.5%, respectively). The HA group also had significantly less loss of correction compared with the TR group at 3-month and 2-year after the operation (CCD difference: -1.6mm vs. 1.6mm, 0.2mm vs. 2.4mm; CCD ratio: 79.3% vs. 122.2%, 100.6% vs. 136.1%, all p<0.05). All three methods achieved significant improvement in function and pain without inter-group differences. No coracoid-related or tunnel complications occurred. DISCUSSION: The hook plate alone, and hook plate with suture anchor augmentation techniques provided less residual vertical instability compared to TightRope fixation at 2-year follow-up. The patient-reported functional outcomes were promising and comparable among the three groups. LEVEL OF EVIDENCE: III, Retrospective comparative therapeutic trial.

The objective of this study is to compare the clinical outcomes after arthroscopic hip labral repair in athletes and non-athletes. The design of this study is a retrospective comparative study. The setting of this study is an institutional study. One hundred and sixteen patients of hip labral tears who underwent arthroscopic labral repair were included. Eighty-five of these patients met the inclusion/exclusion criteria (25 athletes and 60 non-athletes). Hip labral tears underwent arthroscopic labral repair. The main outcome measures are as follows: visual analog scale (VAS) and modified Harris Hip Score (mHHS) 2 years postoperatively and the rate of return to sports at previous level. There was no significant difference in the gender, alpha angle, lateral center-edge angle between the two groups, except for the mean age (19.3 versus 42.2, P < 0.001), Marx activity rating scale (MARS) (14.6 versus 6.8, P < 0.001) and University of California, Los Angeles (UCLA) activity rating scale (9.6 versus 5.0, P < 0.001). The intraoperative findings were similar in the two groups. The VAS scores and mHHS both showed a significant improvement after surgery in both groups (VAS improvement 3.6 and mHHS improvement 22.4 in the athlete group; VAS improvement 3.9 and mHHS improvement 25.0 in the non-athlete group, all P < 0.001). There was no difference in VAS improvement or mHHS improvement between the athlete and non-athlete groups. All the patients in the athlete group return to sports at previous level 6 months after the operation. The mean time of return to sports at previous level was 5.4 months. Both athletes and non-athletes demonstrate significant VAS and mHHS improvement following arthroscopic labral repair. The VAS scores improvement and mHHS improvement were similar in the athlete and non-athlete groups after arthroscopic labral repair.
