Surgical treatment options for plantar fasciitis and their effectiveness: a systematic review and network meta-analysis.

BACKGROUND: To date, there are no systematic reviews on the utility of surgical management for plantar fasciitis to guide best practice. This review aimed to evaluate the operative options for plantar fasciitis and their effectiveness. METHODS: A systematic review and network meta-analysis were carried out in accordance with PRISMA guidelines. A search strategy was conducted on the MEDLINE, EMBASE, and Cochrane databases. Quality was assessed using the ROBINS-I tool. RESULTS: 17 studies involving 865 patients were included. Surgical options considered were open and endoscopic plantar fasciotomy, gastrocnemius release, radiofrequency microtenotomy and dry needling. All interventions resulted in improvement in VAS and AOFAS scores. No major complications were seen from any treatment modality. CONCLUSIONS: Surgical interventions are effective in providing short- to medium-term symptomatic relief for plantar fasciitis refractory to non-operative management. Current evidence is equivocal regarding treatment choice. Further large randomised studies are required to establish long-term outcomes and a management algorithm. LEVEL OF EVIDENCE: Level III.

Long-Term Functional Outcomes Following Radiofrequency Microtenotomy for Lateral Epicondylitis of Elbow.

Background Lateral epicondylitis or 'Tennis elbow' is a common cause of elbow pain in the middle-aged group caused by tendinosis of the common extensor origin of the forearm muscles. Though no obvious aetiology is identified in most cases, it could be attributed to repetitive overuse of wrist extensors or supinator muscles. This condition is generally self-limiting but may become persistent in a few cases. Radiofrequency microtenotomy (RFM) is a minimally invasive surgical procedure for recalcitrant lateral epicondylitis of the elbow. This involves targeted coblation of pathological tissue at significantly lower temperatures. Objectives The aim of this study was to evaluate the therapeutic efficacy and report long-term results and recurrences in patients treated with RFM. Methods We present long-term results with a mean eight-year follow-up in a case series of 19 patients. All patients had a minimum of six months (mean 23.25 months and range: 6-36 months) of conservative management which included steroid injections prior to being offered RFM. This was a retrospective case series of 20 elbows (in 19 patients) who underwent RFM. The majority of patients (65%) were females. The operation was carried out in the dominant arm in 55% of patients. Results Results were analysed by comparing pre-operative and post-operative QuickDASH scores (Disabilities of the Arm, Shoulder and Hand Score) obtained at one year and eight years post-operatively. We found an improvement in QuickDASH scores from a mean of 61.7 pre-operatively to 18.9 (p-value < 0.0001) and 8.5 (p-value < 0.0001) at one year and eight years, respectively. The mean pain component of the QuickDASH scores decreased from 4.8 to 2.0 and 1.5, respectively, at one year and eight years (p-value < 0.0001). More than 83% of the patients had excellent to good functional improvement. Conclusion RFM is a reliable modality for treating recalcitrant lateral epicondylitis of the elbow with excellent long-term results.

Surgical or non-surgical treatment of plantar fasciopathy (SOFT): study protocol for a randomized controlled trial.

BACKGROUND: Plantar fasciopathy is the most common reason for complaints of plantar heel pain and one of the most prevalent musculoskeletal conditions with a reported lifetime incidence of 10%. The condition is normally considered self-limiting with persistent symptoms that often last for several months or years. Multiple treatments are available, but no single treatment appears superior to the others. Heavy-slow resistance training and radiofrequency microtenotomy for the treatment of plantar fasciopathy have shown potentially positive effects on short- and long-term outcomes (> 3 months). However, the effect of heavy-slow resistance training compared with a radiofrequency microtenotomy treatment is currently unknown. This trial compares the efficacy of heavy-slow resistance training and radiofrequency microtenotomy treatment with supplemental standardized patient education and heel inserts in improving the Foot Health Status Questionnaire pain score after 6 months in patients with plantar fasciopathy. METHODS: In this randomized superiority trial, we will recruit 70 patients with ultrasound-confirmed plantar fasciopathy and randomly allocate them to one of two groups: (1) heavy-slow resistance training, patient education and a heel insert (n = 35), and (2) radiofrequency microtenotomy treatment, patient education and a heel insert (n = 35). All participants will be followed for 1 year, with the 6-month follow-up considered the primary endpoint. The primary outcome is the Foot Health Status Questionnaire pain domain score. Secondary outcomes include the remaining three domains of the Foot Health Status Questionnaire, a Global Perceived Effect scale, the physical activity level, and Patient Acceptable Symptom State, which is the point at which participants feel no further need for treatment. DISCUSSION: By comparing the two treatment options, we should be able to answer if radiofrequency microtenotomy compared with heavy-slow resistance training is superior in patients with plantar fasciopathy.

Radiofrequency Microtenotomy or Physical Therapy for Achilles Tendinopathy: Results of a Randomized Clinical Trial.

BACKGROUND: Achilles tendinopathy is a painful disorder, and various treatment options are available. Bipolar radiofrequency microtenotomy (RFM) has shown promising results in treating tendinosis. PURPOSE/HYPOTHESIS: The purpose was to compare the results between treatment with bipolar RFM and physical therapy (PT) for patients with midportion Achilles tendinopathy. It was hypothesized that RFM would be equivalent or superior to PT. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 38 patients with midportion Achilles tendinopathy were evaluated for 2 years. The patients were randomized to receive either RFM or PT. There were 20 patients in the RFM group and 18 patients in the PT group. Clinical outcomes were assessed using the visual analog scale (VAS) for pain and the Foot and Ankle Outcome Score (FAOS). The degree of tendinosis was evaluated with magnetic resonance imaging (MRI) of the affected ankle performed before intervention and 2 years after intervention. RESULTS: In both groups, the VAS scores at the 2-year follow-up were significantly improved compared with preintervention: from 7.2 ± 1.5 to 1.0 ± 1.4 for the RFM group and from 5.9 ± 1.3 to 3.1 ± 1.8 for the PT group (P < .01 for both). Compared with the PT group, the RFM group had significantly better VAS scores at both the 1- and 2-year follow-ups (P < .01 for both) and better scores on 4 of the 5 FAOS subscales at the 2-year follow-up (P < .01 for all). MRI revealed an improvement in the tendinosis score in both groups, without any significant difference between the groups. CONCLUSION: In this randomized study, the clinical assessments revealed significant improvements in the VAS, FAOS, and tendinosis score as seen on MRI 2 years after intervention with either RFM or PT in patients with midportion Achilles tendinopathy. The improvement was significantly better in the RFM group with regard to VAS and FAOS, but not in the MRI appearance. REGISTRATION: NCT03274557 (ClinicalTrials.gov identifier).

Radiofrequency microtenotomy: a promising method for treatment of rotator cuff tendinopathy.

PURPOSE: Subacromial pain syndrome is a common disorder. Arthroscopic subacromial decompression is currently the preferred treatment method. Bipolar radiofrequency microtenotomy has shown promising results in treating tendinosis. In this study, the authors compare the results after arthroscopic acromioplasty with bipolar radiofrequency microtenotomy for patients with subacromial pain syndrome. METHODS: A total of 27 patients, with subacromial pain syndrome, were followed for 2 years. There were 14 patients in the arthroscopic acromioplasty group and 13 patients in the radiofrequency microtenotomy group. Clinical outcome data included pain reported using a visual analog scale, Constant score, and strength. Magnetic resonance imaging of the affected shoulder was performed before and 2 years after intervention for an evaluation of the tendinosis grade. RESULTS: All patients attended the final follow-up 2 years after intervention. No significant differences were found at baseline between the groups. Pain measured by the visual analog scale revealed a significant reduction in both groups at 12 weeks, 6 months and 2 years compared with baseline. There was no significant difference between the groups in terms of visual analog scale, Constant score, or strength. The magnetic resonance imaging revealed a significant improvement in the tendinosis score in both groups, without any significant difference between the groups. CONCLUSION: In this prospective randomized study, the clinical assessments revealed a significant improvement in terms of the visual analog scale, strength, Constant score, and tendinosis score 2 years after intervention with either arthroscopic acromioplasty or radiofrequency microtenotomy in patients with subacromial pain syndrome. However, no significant differences were found between the groups. This study reveals that there are surgical options other than acromioplasty in patients with SAPS. LEVEL OF EVIDENCE: II.

Open release versus radiofrequency microtenotomy in the treatment of lateral epicondylitis: a prospective randomized controlled trial.

BACKGROUND: Optimal surgical treatment of lateral epicondylitis remains uncertain. Recently, radiofrequency microtenotomy (RFMT) has been proposed as a suitable treatment. We compared RFMT with standard open release (OR) in this prospective randomized controlled trial. METHODS: In total, 41 patients with symptoms for at least 6 months were randomized into two groups: 23 patients had RFMT and 18 had OR. Two patients from RFMT withdrew. Each patient underwent Numerical Rating Scale (NRS) pain score, grip strength and Disabilities of the Arm, Shoulder and Hand (DASH) scores pre-operatively and at 6 weeks. Pain and DASH scores were repeated at 6 months and 12 months. RESULTS: NRS pain scores improved by 4.8 points for RFMT and by 3.9 points for OR. There was a significant improvement in both groups from pre-operative scores, although there was no statistically significant difference between the groups at 1 year. Grip strength improved by 31% in the RFMT group compared to 38% in OR. There was no significant difference between the initial and 6 weeks scores or between treatments. At 1 year, DASH was 39.8 points for RFMT and 24.4 points for OR. There was a significant improvement in both groups from pre-operative scores, although there was no statistically significant difference between the groups at 1 year. CONCLUSIONS: Both groups showed significant improvements and similar benefit to the patient. The results of the present study do not show any benefit of RFMT over the standard OR. As a result of the extra expense of RFMT, we therefore recommend that OR is offered as the standard surgical management.

Endoscopic Plantar Fasciotomy vs Open Radiofrequency Microtenotomy for Recalcitrant Plantar Fasciitis.

BACKGROUND: Although usually self-limiting, around 10% of patients develop recalcitrant plantar fasciitis despite conservative treatment. In such cases, operative intervention can be offered. Traditionally, plantar fasciotomy has been the treatment of choice, but recently, there has been a push for more minimally invasive approaches. Radiofrequency microtenotomy has also been increasingly used as a treatment option. In this study, we compare the outcomes of endoscopic plantar fasciotomy and open radiofrequency microtenotomy. METHODS: Patients treated in our institution with either procedure between 2007 and 2015 were included and interviewed at baseline and 3 months, 6 months, and 12 months postoperatively using the American Orthopaedic Foot & Ankle Society (AOFAS) and 36-item Medical Outcomes Short Form (SF-36) questionnaires. They were asked questions to evaluate their expectation and satisfaction postoperatively. Demographic and clinicopathological data were prospectively collected from clinical charts and electronic records. RESULTS: There was no difference in either treatment arms preoperatively and an overall improvement in all functional outcomes postoperatively. However, patients who had endoscopic plantar fasciotomy fared better at 3 months compared to patients who underwent open microtenotomy with the visual analog score component of the AOFAS hindfoot score (HINDVAS) and the social functioning and role-functioning-emotional reaching statistical significance ( P = .027, P = .03, and P = .03, respectively). There was no difference in functional outcomes at 6 or 12 months postoperatively. CONCLUSION: Endoscopic plantar fasciotomy was associated with an earlier improvement in functional outcome in our study. However, both treatments had equivalent outcomes at 1-year follow-up, suggesting that either method is reasonable in the treatment of chronic plantar fasciitis. LEVEL OF EVIDENCE: Level III, comparative study.
