Comparison of Analgesia Treatment Methods After Arthroscopic Rotator Cuff Repair: A Network Meta-analysis of 42 Randomized Controlled Trials.

Background: The optimal method for postoperative analgesia after arthroscopic rotator cuff repair (ARCR) is still unclear. Purpose: To compare the efficacy of postoperative analgesic methods after ARCR through network meta-analysis of randomized controlled trials and prospective controlled trials. Study Design: Systematic review; Level of evidence, 2. Methods: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched PubMed, Embase, and Web of Science from inception until April 12, 2022, for randomized controlled trials and prospective controlled trials evaluating neuraxial analgesia, peripheral nerve block, periarticular local anesthetic infiltration, intravenous patient-controlled analgesia, oral analgesia, or any combination of these methods for pain management after ARCR. Outcomes included pain scores at rest, morphine consumption, and complications (nausea and vomiting). Study quality was assessed using the Cochrane risk-of-bias tool. Network meta-analysis was used to assess the relative efficacy of the methods for postoperative analgesia. The best choice for postoperative analgesia was defined as the one with significant differences in pain scores and morphine consumption compared with placebo, with no significant difference in complications, during the initial 48 hours postoperatively. Results: Included were 42 studies with 3110 patients. Only suprascapular nerve block (SSNB) was significantly superior to placebo in pain scores (mean difference [MD], -0.93 [95% CI, -1.31 to -0.54] at 6 hours; MD, -2.34 [95% CI, -3.49 to -1.19] at 12 hours) and morphine consumption (MD, -17.70 [95% CI, -32.98 to -2.42] at 24 hours) (P < .05 for all), with no difference in complications (odds ratio, 0.96 [95% CI, 0.21 to 4.32]; P > .05). Pain scores were significantly lower with interscalene nerve block compared with SSNB (MD, -0.69 [95% CI, -1.17 to -0.20] at 6 hours; MD, -1.44 [95% CI, -2.21 to -0.67] at 12 hours) and with SSNB + axillary nerve block compared with SSNB (MD, -3.09 [95% CI, -4.18 to -1.99] at 6 hours; MD, -0.87 [95% CI, -1.71 to -0.03] at 12 hours) (P < .05 for all). Conclusion: Based on the current evidence, most analgesic methods lowered pain and morphine consumption compared with placebo. There were significant differences in pain scores between interscalene nerve block and SSNB during the first 12 hours postoperatively, and adding axillary nerve block to SSNB enhanced the analgesic effect.

Total ankle arthroplasty outcome comparison for post-traumatic and primary osteoarthritis.

BACKGROUND: Mobile-bearing total ankle arthroplasty designs have achieved good clinical results for the treatment of ankle osteoarthritis. However, no direct comparison of the outcomes of total ankle arthroplasty has been made between post-traumatic and primary osteoarthritis. The purpose of the present study was to compare the clinical and radiographic outcomes of total ankle arthroplasty in patients with post-traumatic and primary osteoarthritis. MATERIALS AND METHODS: The HINTEGRA total ankle arthroplasty was carried out in 65 patients (67 ankles) with symptomatic ankle osteoarthritis. Group A included 37 patients (37 ankles) with post-traumatic osteoarthritis, whereas Group B included 28 patients (30 ankles) with primary osteoarthritis. Patients were assessed clinically and radiographically at a mean followup of 38 months. RESULTS: No significant differences were found between the two study groups in terms of American Orthopaedic Foot and Ankle Society ankle-hindfoot scales, range of motion, or radiographic values at final followup (p > 0.05). The incidence of complications (38% in Group A, 27% in Group B) and additional procedures (54% in Group A, 27% in Group B) was significantly higher in Group A (p = 0.014 for complications, p = 0.013 for additional procedures). One ankle was revised in Group A for a deep infection. CONCLUSION: The clinical and radiographic outcomes of total ankle arthroplasty for post-traumatic and primary osteoarthritis were comparable, although the incidence of complications after total ankle arthroplasty was higher in the post-traumatic osteoarthritis group. More preceding or concomitant surgeries were required in order to make the post-traumatic cases suitable for total ankle arthroplasty.

Distal chevron osteotomy with distal soft tissue procedure for moderate to severe hallux valgus deformity.

BACKGROUND: Distal chevron osteotomy has been widely employed to treat mild to moderate hallux valgus deformity. The purpose of the present study was to evaluate the outcomes of distal chevron osteotomy with a distal soft tissue procedure for the correction of moderate to severe hallux valgus. MATERIALS AND METHODS: We reviewed 76 patients (86 feet) that underwent distal chevron osteotomy with a distal soft tissue procedure for symptomatic moderate to severe hallux valgus deformity. At a mean followup of 31 months, all patients were evaluated using subjective, objective and radiographic measurements. RESULTS: Ninety-four percent of the patients were very satisfied or satisfied. Average AOFAS score improved from 54.7 points preoperatively to 92.9 at final followup. Average hallux valgus angle changed from 36.2 degrees preoperatively to 12.4 degrees at final followup, and average first-second intermetatarsal angle changed from 17.1 to 7.3 degrees. Average tibial sesamoid position changed from 2.4 preoperatively to 1.2 at final followup. Dorsal angulation of the head was observed in two feet, and plantaflexion of the head in four feet. There were no cases of avascular necrosis of the metatarsal head. CONCLUSION: Our results indicate that distal chevron osteotomy with a distal soft tissue procedure provides an effective and reliable means of correcting moderate to severe hallux valgus deformity, and that it does so with high levels of patient satisfaction and low incidence of complications.

Arthroscopic microfracture for osteochondral lesions of the talus.

The purpose of the present study was to evaluate the outcomes of arthroscopic microfracture for isolated osteochondral lesions of the talus without combined lesions, in patients of less than 50 years old with lesions of <1.5 cm(2). Thirty-five patients (35 ankles) with isolated osteochondral lesions of the talus were treated by arthroscopic microfracture. There were 27 men and 8 women of average age 35 years (range 17-50) and mean body mass index (BMI) 25 kg/m(2) (range 20-34) at the time of surgery. Clinical outcome evaluations were performed at a mean follow-up of 33 months. Overall results, as determined using American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scores, were excellent in 16 (46%), good in 15 (43%), and fair in 4 (11%). Mean AOFAS scores improved from 63 points (range 52-77) preoperatively to 90 points (range 73-100) at final follow-up, median Ankle Activity Score (AAS) from 3 points (range 1-5) to 6 points (range 3-8), mean Visual Analogue Scale (VAS) scores from 7 points (range 5-8) to 2 points (range 0-5), and mean Short Form-36 scores showed improvements in physical function, role limitation, bodily pain, social function, and general health (P < 0.05). In terms of prognostic factors, a longer symptom duration was found to negatively affect outcome, as determined by AOFAS scores, AAS, and VAS scores. Arthroscopic microfracture for isolated osteochondral lesions of the talus is a safe and effective procedure, which provides good clinical outcomes in the majority of patients.

Second-look arthroscopic findings and clinical outcomes after microfracture for osteochondral lesions of the talus.

BACKGROUND: Arthroscopic microfracture is frequently used to repair osteochondral lesions of the talus. However, despite the popularity of this technique, no study has been conducted on cartilage repair after microfracture by second-look arthroscopy. PURPOSE: The purpose of the present study was to evaluate cartilage repair in osteochondral lesions of the talus by second-look arthroscopy and to compare arthroscopic findings with clinical outcomes 12 months postoperatively. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Second-look arthroscopies were performed in 20 ankles of 19 patients at 12 months postoperatively. Arthroscopic findings were classified using the Ferkel and Cheng staging system, and cartilage repair was assessed using the International Cartilage Repair System (ICRS). Clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale. RESULTS: According to the Ferkel and Cheng staging at second-look arthroscopy, 7 of the 20 ankles (35%) showed incomplete healing (stage D). In terms of ICRS overall repair grades, 8 ankles (40%) were abnormal (grade III). Mean AOFAS scores for Ferkel and Cheng stages A to C (n = 13) and stage D (n = 7) were 88.5 and 82.0 points, and those for ICRS repair grades I and II (n = 12) and grade III (n = 8) were 88.7 and 82.5, respectively. Good correlations were found between AOFAS scores and Ferkel and Cheng stages and ICRS grades. Overall, 90% of ankles achieved an excellent or good AOFAS score of over 80 points. CONCLUSION: Second-look arthroscopic findings at 12 months postoperatively after microfracture for osteochondral lesions of the talus revealed that 40% of lesions were incompletely healed. Nevertheless, the majority of patients achieved a good clinical outcome. Furthermore, postoperative clinical scores were found to be correlated with ICRS repair grades.

Efficacy of MRI versus arthroscopy for evaluation of sinus tarsi syndrome.

BACKGROUND: Magnetic resonance imaging (MRI) has been used to diagnose sinus tarsi syndrome (STS) because of its non-invasiveness and accuracy. The purpose of the present study was to evaluate the diagnostic efficiency of MRI compared with subtalar arthroscopy for STS. MATERIALS AND METHODS: Twenty-eight patients (30 feet) who had undergone both MRI and subtalar arthroscopy for STS were evaluated. MRI results were compared with arthroscopic findings, which were considered the standard. Sensitivity, specificity, and positive and negative predictive values were calculated, and correlations between MRI and arthroscopic findings were investigated. RESULTS: MRI was found to detect interosseous talocalcaneal ligament (ITCL) tears, cervical ligament (CL) tears, sinus tarsi fat alterations, and synovial thickening, with sensitivities, specificities, positive and negative predictive accuracies of: 44%, 60%, 85%, 18% (ITCL tears); 73%, 89%, 80%, 86% (CL tears); 71%, 92%, 93%, 71% (sinus tarsi fat alterations); and 86%, 87%, 67%, 95% (synovial thickening). Correlations between MRI and arthroscopic findings showed full agreement in 10%, partial agreement in 50%, and no agreement in 40%. CONCLUSION: MRI is useful for detecting CL tears, sinus tarsi fat alterations, and synovial thickening, but is inadequate for correctly detecting ITCL tears.

Subtalar arthroscopy for sinus Tarsi syndrome: arthroscopic findings and clinical outcomes of 33 consecutive cases.

PURPOSE: The purposes of this study were to identify the pathologic findings of sinus tarsi syndrome (STS) by subtalar arthroscopy and to evaluate the results of arthroscopic treatments in 33 consecutive cases. METHODS: A retrospective review was performed in 31 consecutive patients (33 cases) who underwent subtalar arthroscopic treatment for STS. The mean follow-up duration was 24 months (range, 18 to 36 months). Patients were evaluated by use of arthroscopic findings (recorded on videotapes and photographs) and clinical outcomes, which included visual analog scale and American Orthopaedic Foot and Ankle Society ankle-hindfoot scores. RESULTS: Arthroscopic findings showed partial tear of the interosseous talocalcaneal ligament in 29 cases (88%), synovitis in 18 (55%), partial tear of the cervical ligament in 11 (33%), arthrofibrosis in 8 (24%), and soft-tissue impingement in 7 (21%). The mean visual analog scale score improved from 7.3 points (range, 6 to 9 points) preoperatively to 2.7 points (range, 1 to 4 points) postoperatively (P < .005), and the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from 43.1 points (range, 21 to 65 points) preoperatively to 86.2 points (range, 72 to 100 points) postoperatively (P < .005). Of the cases, 16 (48%) had an excellent result, 13 (39%) had a good result, and 4 (12%) had a fair result. CONCLUSIONS: Subtalar arthroscopy identified pathologies in the subtalar joint in patients with STS and showed that treatment of these pathologies led to improved function. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

A comparison of arthroscopic and MRI findings in staging of osteochondral lesions of the talus.

The purpose of the present study was to evaluate the accuracy of MRI compared with arthroscopy in staging of osteochondral lesions of the talus (OLTs). The authors prospectively investigated 50 patients (52 cases) who had undergone both MRI and ankle arthroscopy for OLTs. The 30 males (32 ankles) and 20 females (20 ankles) had an average age of 43 years (range 19-64 years). The correlations between MRI and arthroscopic stagings were also investigated. Preoperative MRI resulted in 7 stage I, 11 stage II, 25 stage III, and 9 stage IV lesions, and ankle arthroscopic findings in 3 stage I, 5 stage II, 35 stage III, and 9 stage IV lesions. No stage V lesion was encountered. A comparison of MRI and arthroscopic stagings revealed that MRI had an accuracy of 81% (42 of 52) for staging of OLTs. MRI correctly staged 3 of 7 stage I lesions, 5 of 11 stage II, 25 of 25 stage III, and 9 of 9 stage IV lesions. Ten mismatched cases were of arthroscopic stage III lesions, which MRI classified as four stage I lesions and six stage II lesions. Thus, MRI staging tended to understate lesion severity. We re-reviewed the ten MR images of the mismatching cases to identify reasons for these mismatches, and subchondral edema was found in six cases. The authors conclude that MRI has accuracy of 81% in staging of OLTs, however, MRI had some limitation in correct staging isolated cartilage lesions of OLTs, especially combined with subchondral edema.
