Effect of age and gender in rates of achieving minimal clinically important difference and patient-acceptable symptom state 2 years after arthroscopic superior capsular reconstruction.

PURPOSE: This study aimed to evaluate patient-reported outcome measures (PROMs) and the effects of gender and age on achieving clinically significant outcomes in patients undergoing arthroscopic superior capsular reconstruction (ASCR) with a minimum 2-year follow-up. METHODS: Patients undergoing ASCR for irreparable rotator cuff tear between 2013 and 2020 were reviewed. Preoperative and minimum 2-year postoperative PROMs were collected, including American Shoulder and Elbow Surgeons (ASES), Constant, single assessment numeric evaluation (SANE), and visual analog scale (VAS) scores. Minimal clinically important difference (MCID) and patient-acceptable symptomatic state (PASS) were calculated for each functional score and analyzed according to age and gender. The percentages of patients achieving MCID and PASS were recorded. RESULTS: The study included 83 patients, with a mean follow-up of 3.5 ± 1.4 years. Significant improvements were found in ASES, Constant, SANE, and VAS for all groups based on gender and age. Based on receiver-operating characteristic curves, all scores had acceptable areas under the curve for PASS. Values for PASS and MCID were 81.5 and 10.3 for ASES; 61.5 and 6.2 for Constant; 82.5 and 11.5 for SANE and 1.5 and 1.1 for VAS, respectively. Analysis of achieving MCID and PASS showed no difference between the groups in the majority of outcome measures. However, female patients achieved the SANE thresholds for PASS at significantly higher rates than male patients. Patients ≥65 years old achieved ASES and Constant thresholds for MCID at significantly higher rates than patients ˂65 years old. CONCLUSION: Most patients achieved MCID and PASS at a 2-year follow-up. Patients showed comparable rates of MCID and PASS achievement on most outcome tools based on age and gender. Female patients achieved PASS on SANE at significantly higher rates than male patients and older patients achieved MCID on ASES and Constant at higher rates than young patients. Thus, age is a stronger factor for achieving MCID than gender. LEVEL OF EVIDENCE: Level II.

Cross-Sectional Area of the Median Nerve as a Prognostic Indicator in Carpal Tunnel Syndrome Treated With Local Steroid Injection.

PURPOSE: Local steroid injection is an effective treatment modality for carpal tunnel syndrome. This study aimed to investigate the success rate of ultrasonography-guided local steroid injection and determine the prognostic value of the cross-sectional area (CSA) of the median nerve for steroid injection. METHODS: We retrospectively evaluated 40 patients with carpal tunnel syndrome whose median nerve CSA was >15 mm2 (large-CSA group; n = 16) or ≤15 mm2 (small-CSA group; n = 24). The CSA was measured using ultrasonography, and all the patients were treated with ultrasonography-guided corticosteroid injection. Demographic characteristics, symptoms, initial QuickDASH score, Boston Carpal Tunnel Questionnaires, and results of the nerve conduction study were assessed at baseline. Treatment success was defined in this study as the absence of symptom recurrence within the entire follow-up period. RESULTS: The treatment success rate was 45% (n = 18) after an average follow-up of 16 months. Overall, 11 patients (28%) underwent carpal tunnel release on an average of 11 months after steroid injection. The large-CSA group showed a significantly worse grade of electrodiagnostic testing at baseline than did the small-CSA group; however, there was no significant difference in final Boston Carpal Tunnel Questionnaires symptom score (1.7 vs 1.8, respectively) and the rate of continued treatment success at the last follow-up (42% vs 50%, respectively). The proportions of patients who required carpal tunnel decompression were 29% and 25% in the small-CSA and large-CSA groups, respectively. CONCLUSIONS: Local steroid injection for carpal tunnel syndrome has an overall success rate of 45% after a mean follow-up of 16 months. Preinjection CSA was not associated with whether the steroid injection was considered successful. This indicates that increased median nerve CSA does not preclude the possibility of symptomatic relief after a local steroid injection. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Patient Acceptable Symptom State, Minimal Clinically Important Difference, and Substantial Clinical Benefit After Arthroscopic Superior Capsular Reconstruction.

BACKGROUND: Patient Acceptable Symptom State (PASS), minimal clinically important difference (MCID), and substantial clinical benefit (SCB) have rarely been assessed after arthroscopic superior capsular reconstruction (ASCR) with fascia lata autograft. PURPOSE: (1) To investigate PASS, MCID, and SCB values for pain visual analog scale (pVAS), American Shoulder and Elbow Surgeons (ASES) score, Constant score, and Single Assessment Numeric Evaluation (SANE) after ASCR with fascia lata autograft, (2) to investigate factors for achieving PASS, MCID, and SCB. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: We retrospectively collected data from patients who underwent ASCR between June 2013 and October 2020. A total of 88 patients were included, and anchor questions for deriving PASS, MCID, and SCB values were applied at a minimum 1-year follow-up postoperatively. PASS, MCID, and SCB were derived using sensitivity- and specificity-based approaches. Univariable and multivariable logistic regression analyses were performed to determine factors for achieving PASS, MCID, and SCB. RESULTS: Based on receiver operating characteristic curves, all 4 scores had acceptable area under the curve values (>0.7) for PASS, MCID, and SCB values. The PASS, MCID, and SCB values were 1.5, 2.5, and 4.5 for pVAS; 81.0, 19.0, and 27.5 for the ASES score; 60.5, -0.5, and 5.5 for the Constant score; and 75.0, 27.5, and 32.5 for SANE, respectively. Poor preoperative scores were related to significantly higher odds ratios (ORs) for achieving MCID and SCB. Wide acromiohumeral distance and dominant side were related to higher ORs for achieving PASS for the ASES score, and subscapularis tear was related to lower ORs for achieving PASS for pVAS and SCB for the Constant score. CONCLUSION: Reliable PASS, MCID, and SCB values were achieved for at least 1 year after ASCR surgery. Poor preoperative score, wide acromiohumeral distance, and dominant side all demonstrated higher ORs for at least one value, but a subscapularis tear demonstrated lower ORs for achieving PASS for pVAS and SCB for the Constant score.

Modified Staged Finkelstein Test for the Identification of Intracompartmental Septum in Patients with De Quervain's Disease.

Background: The intracompartmental septum isolating the extensor pollicis brevis (EPB) has been reported to affect the patient's response to nonsurgical treatment in de Quervain's disease. A simple physical test called the modified staged Finkelstein test was developed to evaluate the septum; the result of this test was compared with those of the pre-existing physical test (EPB entrapment test) and ultrasonographic (US) examination of the septum. Methods: We retrospectively analyzed 52 patients who underwent two clinical tests, including the modified staged Finkelstein test and the EPB entrapment test, and US examination for de Quervain's disease. The correlation between the clinical test results and US findings was evaluated; sensitivity, specificity, and positive and negative predictive values were calculated. Results: The proportion of wrists with a separate septum was 50% (26 patients) in the US examination. The sensitivity and specificity of the modified staged Finkelstein test were 88.5% and 73.1%, respectively; those of EPB entrapment test were 71.4% and 84.2%, respectively. The positive and negative predictive values of the modified staged Finkelstein test were 76.7% and 86.4%, respectively. Conclusions: The modified staged Finkelstein test showed acceptable diagnostic values for the diagnosis of septum compared with pre-existing physical tests. Knowledge about the existence of septum could be helpful in treating patients and expecting prognosis.

Endoscopic repair of delayed stomach perforation caused by penetrating trauma: A case report.

BACKGROUND: Primary endoscopic closure of a perforated gastric wall during endoscopic procedures is mostly effective and well-tolerated; however, there are very few studies on the efficacy of endoscopic management of delayed traumatic gastric perforation. Herein, we report a novel case of a patient who was successfully treated for delayed traumatic stomach perforation using an alternative endoscopic modality. CASE SUMMARY: A 39-year-old woman presented with multiple penetrating traumas in the back and left abdominal cavity. Initial imaging studies revealed left diaphragmatic disruption and peri-splenic hemorrhage without gastric perforation. An emergency primary repair of the disrupted diaphragm with omental reduction and suturing of the lacerated lung was performed; however, delayed free perforation of the gastric wall was noted on computed tomography after 3 d. Following an emergency abdominal surgery for the primary repair of the gastric wall, re-perforation was noted 15 d postoperatively. The high risk associated with re-surgery prompted an endoscopic intervention using 2 endoloops and 11 endoscopic clips using a novel modified purse-string suture technique. The free perforated gastric wall was successfully repaired without additional surgery or intervention. The patient was discharged after 46 d without any complications. CONCLUSION: Endoscopic closure with endoloops and clips can be a useful therapeutic alternative to re-surgery for delayed traumatic gastric perforation.

Effect of the additional first ray osteotomy on hindfoot alignment after calcaneal osteotomy for the correction of mild-to-moderate adult type pes plano-valgus.

PURPOSE: To determine the effect of the additional first ray osteotomy on hindfoot alignment for the correction of pes plano-valgus. METHODS: Data obtained from 37 consecutive patients recruited from 2006 to 2014 who underwent medial displacement calcaneal osteotomy (MDCO) alone (group H) or MDCO followed by medial cuneiform opening wedge osteotomy (MCOWO) (group HF) with a minimum 1-year follow-up were reviewed retrospectively. The mean follow-up periods were 34 and 32 months. RESULTS: Degree of decrease of Talonavicular coverage angle (TNCA) via surgery or postoperative TNCA on standing foot AP radiographs were not significantly different between group H and HF ( p = 0.287). The calcaneal pitch angle and medial cuneiform height on the standing foot lateral radiographs was significantly increased after operation in group HF ( p = 0.01), there was a significant difference with group H as well ( p = 0.033). In group HF, the Meary's angle was significantly decreased after operation, a significant difference compared to group H ( p = 0.009). Hindfoot alignment angle on the hindfoot alignment view was decreased after operation in both groups but was not significantly different between both groups ( p = 0.410). Hindfoot alignment ratio was also increased after the operation in both groups, but was not different between two groups ( p = 0.783). CONCLUSION: The additional first ray osteotomy using MCOWO had no correctional power for hindfoot correction, although it caused improvement in some radiographic parameters.

Total knee arthroplasty after failed high tibial osteotomy: a systematic review of open versus closed wedge osteotomy.

PURPOSE: Medial opening wedge high tibial osteotomy (HTO) has become increasingly popular as an alternative to lateral closing wedge osteotomy for the treatment of medial compartment knee osteoarthritis with varus deformity. The present systematic review was conducted to provide an objective analysis of total knee arthroplasty (TKA) outcomes following previous knee osteotomy (medial opening wedge vs. lateral closing wedge). METHODS: A literature search of online databases (MEDLINE, EMBASE, Cochrane Library database) was made, in addition to manual search of major orthopaedic journals. The methodological quality of each of the studies was assessed on the Newcastle-Ottawa Scale and Effective Practice and Organization of Care. A total of ten studies were included in the review. There were eight studies with Level IV and two studies with Level III evidence. RESULTS: Eight studies reported clinical and radiologic scores. Comparative studies between TKA following medial opening and lateral closing wedge HTO did not demonstrate statistically significant clinical and radiologic differences. The revision rates were similar. However, more technical issues during TKA surgery after lateral closing wedge HTO were mentioned than the medial open wedge group. The quadriceps snip, tibial tubercle osteotomy, and lateral soft tissue release were more frequently needed in the lateral closing wedge HTO group. In addition, because of loss of proximal tibia bone geometry in the lateral closing wedge HTO group, concerns such as tibia stem impingement in the lateral tibial cortex was noted. CONCLUSION: The present systematic review suggests that TKA after medial opening and lateral closing wedge HTO showed similar performance. Clinical and radiologic outcome including revision rates did not statistically differ from included studies. However, there are more surgical technical concerns in TKA conversion from lateral closing wedge HTO than from the medial opening wedge HTO group. LEVEL OF EVIDENCE: IV.
