In this retrospective study, in which we evaluated administration of PRP for chronic tendinopathy, we found that the majority of patients reported a moderate (>50%) improvement in pain symptoms.
Objective Trigger finger at the A1 pulley is a common cause of hand pain leading to functional limitations. This study evaluated the outcomes of patients treated with a microinvasive ultrasound-guided trigger finger release technique using an 18 blade and described three tests that confirm a complete release. Design A retrospective chart review and cross-sectional study of 46 cases of A1 pulley trigger finger releases in 28 patients performed at a private, sports medicine clinic using this technique were completed, meeting power criteria. The primary outcome measure was the resolution of mechanical catching/locking; secondary outcome measures were reduction in visual analog scale for pain and improvement of function in the modified Nirschl scale. Results Complete release was achieved in all patients, with no recurrence of catching/locking during the first year (P < 0.0001). Ninety-eight percent of patients had significant pain and functional improvement (P < 0.0001). There were no complications perioperatively and postoperatively. The three confirmatory tests ensured that all cases obtained a successful outcome. Conclusion This technique combined with confirmatory tests resulted in full resolution of the locking for all patients and statistically significant reduction in pain and improvement in function.
SUMMARY There is considerable interest amongst clinicians and researchers to create the optimal platelet product to maximize outcomes with platelet-rich plasma (PRP) injections. PRP has been widely introduced as a safe alternative for treating tendinopathies. However, there is still limited clinical evidence describing the components of the platelet product and supporting its use in clinical trials. This article reviews the current literature regarding the role of PRP injections in the treatment of recalcitrant tendinopathies and the different factors in the platelet product that could affect the outcome, including the platelet count, presence of leukocytes, activators used, pH of solution and delivery method, among others. In addition, we address important concepts regarding rehabilitation after PRP procedures, which has little consensus to date and is the subject of much debate. Based on the phases of soft tissue healing, basic science research on platelets, as well as our clinical experience in treating over 500 patients with PRP, we will suggest guidelines regarding the optimal progression of rehabilitation and timing for return to previous activity following the procedure.
Background Open surgical trigger finger release has limited success and the risk of complications; however, percutaneous techniques offer a successful alternative. There is limited understanding of the success of percutaneous trigger finger release. Objective To prospectively evaluate the functional outcomes of patients with Green classification Grade 2 to 4 trigger finger treated with an ultrasound‐guided microinvasive trigger finger release using a special 18‐gauge needle with a blade at the tip. Design Prospective, case‐series study. Setting This study took place at an academic institution by one sports medicine physician (R.E.C.) with subspecialty training and certification in musculoskeletal ultrasound. Patients Sixty patients (79 cases) met criteria and agreed to participate in this study; 19 patients had multiple fingers treated. Average patient age was 62.8 years (SD 10.2). Average trigger finger severity diagnosis was Grade 3. Interventions Patients were treated with an ultrasound‐guided microinvasive trigger finger release using a special 18‐gauge needle with a blade at the tip. Main Outcome Measurements Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), numerical rating scale (NRS), and Nirschl scores were captured preprocedure, at various time points, and at final follow‐up. Changes between preprocedure and final follow‐up were analyzed by paired t test (p < .05). Differences were also analyzed between finger, grade level, and gender by repeated measures analyses of variance (p < .05). Results No adverse events were documented perioperatively or postoperatively. Average follow‐up time was 18.4 months (SD 4.6). At final follow‐up, 100% of patients reported no recurrence of catching/locking, 97% had complete resolution of symptoms and significant improvement in QuickDASH scores, and 99% required no further treatment. All measurements showed a decrease in pain and symptoms over time. The improvements in QuickDASH score, NRS, and Nirschl scale and the resolution of mechanical symptoms were all statistically significant. Conclusions Ultrasound‐guided release using the 18‐gauge needle with a blade provides significant functional improvement and full resolution of mechanical symptoms with minimal adverse events.
Background: Plantar fasciitis is the most common cause of heel pain in adults. Multiple conservative treatment plans exist; however, some cases do not obtain significant clinical improvement with conservative treatment and require further intervention. This retrospective case study evaluated the success rate of percutaneous plantar fasciotomy and confounding comorbidities that negatively affect outcomes. Methods: A series of 41 patients treated with percutaneous plantar fasciotomy using the Topaz EZ microdebrider coblation wand were invited to participate in this retrospective follow-up study, and 88% ( N = 36) participated. A limited chart review was completed and the patients answered a survey with the visual analog scale (VAS) for pain and the Foot and Ankle Ability Measure (FAAM) questionnaire. Average outcomes were calculated and 45 variables were analyzed to determine if they were statistically significant confounders. Patients had symptoms for an average of 3 years before the procedure and were contacted for follow-up at an average of 14 months after the procedure. Results: The average VAS for pain score was 1.3 ± 1.8 and the average FAAM score was 92 ± 15. Eighty-nine percent of patients had a successful outcome, defined as FAAM greater than 75. In addition, patients at 18 months postprocedure reported complete or near-complete resolution of symptoms with an FAAM score greater than 97. Concurrent foot pathologies (eg, tarsal tunnel syndrome), oral steroid treatment prior to the procedure, and immobilization with a boot prior to the procedure were statistically significant negative confounders ( P < .05). Being an athlete was a positive confounder ( P = .02). Conclusion: Percutaneous plantar fasciotomy using a microdebrider coblation was an effective treatment for plantar fasciitis, particularly without concurrent foot pathology, with a low risk of complications. Level of Evidence: Level IV, retrospective case series.
De Quervain tenosynovitis is an overuse syndrome associated with inflammation of the tendons in the first dorsal compartment of the wrist. Management includes activity modification, splinting, and corticosteroid injections. In refractory cases, surgical release may be performed, which may be complicated by incomplete release, tendon subluxation, or radial nerve injury. Alternatively, ultrasound-guided release may improve patient satisfaction and outcomes through faster recovery time as well as improved visualization of subcompartments and neurovascular structures. To the best of the authors' knowledge, this is the first case in the literature describing a novel technique for ultrasound-guided first dorsal compartment release for refractory de Quervain tenosynovitis.
