Midterm results of intra-articular stromal vascular fraction injection for the treatment of knee osteoarthritis

PURPOSE

This study aimed to evaluate the safety and efficacy of intra-knee stromal vascular fraction (SVF) injection in patients with symptomatic knee osteoarthritis at the midterm (3-year) follow-up.

METHODS

SVF injection was applied to 25 knees of 20 patients. Eighteen patients (90%) were female, and the means ± standard deviations of age was 61.9 ± 7.8 (range, 50-76) years. Patients who received conservative treatment for at least 6 months and had radiographic Kellgren-Lawrence (K-L) grades 2 and 3 varus gonarthrosis were included in the study. SVF was obtained from the umbilical region by liposuction using local anaesthesia. Patients were followed-up for 36 months. Their visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lysholm scores were evaluated before and at 6, 12, 24 and 36 months post-SVF injection.

RESULTS

A statistically significant improvement (p < 0.05) was observed in VAS, WOMAC and Lysholm scores at the first 2-year follow-up compared to baseline. However, no statistically significant difference (n.s.) was observed in VAS, WOMAC and Lysholm scores at the 3-year follow-up compared with baseline.

CONCLUSION

Intra-articular SVF injection decreased pain and significantly improved the functional outcomes in the first 2 years in knees with grade 2-3 osteoarthritis; however, these positive effects of the injection disappeared in the 3rd year. Although short-term successful results of SVF have been reported in the literature, prospective studies are needed for medium- and long-term results.

Percutaneous release for trigger thumb in children under local anesthesia

Trigger thumb surgery can be performed through open surgery or percutaneous release. Open surgery often requires hospitalization, an operating room, a surgical incision, and postoperative wound care; however, percutaneous release does not require hospitalization or surgery, and is relatively easier and faster. We aimed to assess the results of percutaneous A-1 pulley release using local anesthesia without hospitalization for the treatment of pediatric trigger thumb. In this retrospective study, we included patients operated on between March 2013 and August 2020 with the diagnosis of trigger thumb. The percutaneous release under local anesthesia was applied to all the children by one orthopedic surgeon. All percutaneous release procedures were performed in outpatient clinic conditions. There were 183 children (218 thumbs) who were enrolled in the clinic. Eighty-seven patients were male (47.5%) and 96 were female (52.5%). The average follow-up duration was 5 years (1-8.5 years). Among the 218 trigger thumb cases, 211 were satisfactory (successful result rate 96.8%). Relapse was seen in only 3 thumbs in the early postoperative period. No patient experienced neurovascular deficit or infection. The percutaneous surgical release in pediatric trigger thumb treatment is a simple, minimally invasive procedure that can be done in an outpatient setting under local anesthesia. In addition, the procedure duration is short and has minimal complication rates and maximum patient satisfaction. Level of Evidence III.

Does Surgical Experience Affect the Outcomes During Percutaneous Release of the Trigger Finger?

Background Trigger finger is a condition characterized by clicking or locking during finger movement, sometimes resulting in the freezing of a finger in flexion or extension. The aim of our retrospective study was to determine the effect of the surgeon's learning curve on clinical outcomes in percutaneous release of the trigger finger. In addition, we evaluated the effects of diabetes and local steroid injections on clinical outcomes. Methodology A total of 954 trigger fingers in 678 patients were reviewed from 2012 to 2022. All percutaneous release procedures were performed by a single surgeon in our institute under local anesthesia. The main outcome measures were recurrence and patient satisfaction. In addition, all patients were evaluated in terms of re-operation and complications. The mean follow-up period was 54.87 months. Results There was complete relief of symptoms in 636 (93.81%) patients, and 22 (3.24%) patients had mild pain but were satisfied. We found that the success rate increased over time. The success rate was 91.4% in the first three years and increased to 98.25% in the next seven years (p = 0.001). There was no statistically significant difference between the diabetic and non-diabetic groups in terms of recurrence, satisfaction rate, and complications (p > 0.05). There was no statistically significant difference in terms of recurrence, satisfaction rate, and complications between the groups that received and did not receive steroid injections (p > 0.05). Conclusions Percutaneous release is a safe and reliable procedure in the treatment of trigger fingers, and the success rate increases as the experience increases. Moreover, diabetes mellitus and steroid injections did not affect the clinical results.

Is Intraoperative Bleeding Control Useful After Tourniquet Release in Arthroscopic Anterior Cruciate Ligament Reconstruction?

Background Arthroscopic anterior cruciate ligament (ACL) reconstruction is a common orthopedic surgery, and rehabilitation is very important to achieve successful postoperative results. Postoperative hemarthrosis causes pain and limitation of movement, which prolongs the rehabilitation period. For these reasons, various strategies are used to reduce hemarthrosis in patients undergoing ACL reconstruction. This study aimed to evaluate the effect of bleeding control after releasing the tourniquet in ACL reconstruction surgery on the amount of hemarthrosis and pain in the postoperative period. Methodology A total of 60 patients who underwent arthroscopic single-bundle ACL reconstruction were enrolled in this prospective randomized control study. Bleeding control with the radiofrequency (RF) probe after releasing the tourniquet was done at the end of the arthroscopic ACL reconstruction in 30 patients (coagulation group) while bleeding control was not done for the other 30 patients (control group). Both groups were compared in terms of the degree of hemarthrosis using the Coupens and Yates classification in the early postoperative period and the degree of pain using the Visual Analog Scale (VAS) score and postoperative complications. Results In both groups, isolated ACL reconstruction was performed in 10 patients, additional partial meniscectomy in three patients, and additional arthroscopic meniscus repair in 17 patients. There was no statistically significant difference between the coagulation and control groups in terms of VAS (p > 0.05) and the degree of hemarthrosis (p > 0.05). Although the duration of tourniquet application was similar in both groups (p = 0.78), the duration of anesthesia was significantly longer in the coagulation group (p = 0.001). There was no significant difference between the groups in terms of postoperative complications. Conclusions Bleeding control with the RF probe after tourniquet release does not yield superior outcomes. More research with larger populations is needed to confirm these findings.
