Abstract
Background This case series aimed to introduce surgical management for refractory medial epicondylitis based on the anatomical characteristics of the flexor pronator origin and present the surgical results. Methods Ten elbows from 8 patients (2 males and 6 females; mean age 50.2 years) were included in this case series. All patients underwent resection of the degenerated anterior common tendon and repair using suture anchors. Ulnar neuritis was observed in 9 elbows of 7 patients who underwent the relevant additional surgery. Results Medial elbow pain was resolved in all patients, and pain provocation tests (wrist flexion test and forearm pronation test) were negative postoperatively. The mean Patient-Rated Elbow Evaluation (Japanese version) score was significantly improved from 79.6 ± 7.7 (range, 64.3-92) preoperatively to 8.4 ± 15.2 (range, 0-50) at the final follow-up. Conclusion Angiofibroblastic tendinosis of the anterior common tendon might be an essential pathology of medial epicondylitis, and anterior common tendon resection and repair could be the most appropriate treatment for medial epicondylitis.

Pediatric thrower's elbow: maturation-dependent MRI findings in symptomatic baseball players. Pediatr Radiol 2024; 54:105-116. [PMID: 38015294 DOI: 10.1007/s00247-023-05817-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 11/09/2023] [Accepted: 11/13/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND Elbow pain is common among youth baseball players and elbow MRI is increasingly utilized to complement the clinical assessment. OBJECTIVE To characterize, according to skeletal maturity, findings on elbow MRI from symptomatic youth baseball players. MATERIALS AND METHODS This IRB-approved, HIPAA-compliant retrospective study included pediatric (<18 years of age) baseball players with elbow pain who underwent MRI examinations between 2010 and 2021. Two radiologists, blinded to the outcome, independently reviewed examinations to categorize skeletal maturity and to identify osseous and soft tissue findings with consensus used to resolve discrepancies. Findings were compared between skeletally immature and mature patients and logistic regression models identified predictors of surgery. RESULTS This study included 130 children (115 boys, 15 girls): 85 skeletally immature and 45 mature (12.8±2.3 and 16.2±1.0 years, respectively, p<0.01). Kappa coefficient for interobserver agreement on MRI findings ranged from 0.64 to 0.96. Skeletally immature children, when compared to mature children, were more likely to have elbow effusion (27%, 23/85 vs 9%, 4/45; p=0.03), medial epicondyle marrow edema (53%, 45/85 vs 16%, 7/45; p<0.01), avulsion fracture (19%, 16/85 vs 2%, 1/45; p=0.02), and juvenile osteochondritis dissecans (OCD, 22%, 19/85 vs 7%, 3/45; p=0.04), whereas skeletally mature children were more likely to have sublime tubercle marrow edema (49%, 22/45 vs 11%, 9/85; p<0.01) and triceps tendinosis (40%, 18/45 vs 20%, 17/85; p=0.03). Intra-articular body (OR=4.2, 95% CI 1.5-47.8, p=0.02) and osteochondritis dissecans (OR=3.7, 95% CI 1.1-11.9, p=0.03) were independent predictors for surgery. CONCLUSION Differential patterns of elbow MRI findings were observed among symptomatic pediatric baseball players based on regional skeletal maturity. Intra-articular body and osteochondritis dissecans were independent predictors of surgery.

Comparison of Clinical Outcomes of Platelet-Rich Plasma for Epicondylitis, Elbow: Simultaneous Lateral and Medial Versus Lateral Versus Medial. Orthop Surg 2023; 15:2110-2115. [PMID: 37052071 PMCID: PMC10432457 DOI: 10.1111/os.13732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 12/23/2022] [Accepted: 01/25/2023] [Indexed: 04/14/2023] Open
Abstract
OBJECTIVE Lateral and medial epicondylitis are relatively common diseases, but they do not improve quickly and are known to reduce patients' quality of life. Much research has been done on Platelet-Rich Plasma (PRP) as a treatment for lateral epicondylitis, but research on medial epicondylitis is lacking. The purpose of this study is to compare: (i) the pain intensity; and (ii) the functional outcome between the simultaneous treatment of medial and lateral epicondylitis and the treatment of only lateral or medial epicondylitis using PRP. METHODS In this retrospective study, 209 patients treated with PRP on epicondylitis between March 2018 and December 2021 were enrolled. Simultaneous treatment was underwent 68 patients (group I). Seventy patients were treated for lateral epicondylitis (group II). The remaining 71 patients were treated for medial epicondylitis (group III). The visual analogue scale for pain (VAS) and the Mayo elbow performance score (MEPS) were evaluated for clinical outcomes at the initial visit and 6 months after injection. RESULTS VAS for pain and MEPS showed significant improvement in all three groups compared to before treatment. There was no significant difference between three groups on -ΔVAS (P > 0.05). However, in case of ΔMEPS, group III showed significantly lower compared to groups II and III (P < 0.05). No patients showed worsening of symptoms or complications during the treatment. CONCLUSION PRP injection for the patient with elbow medial and lateral epicondylitis can be treated effectively simultaneously in terms of pain. From a functional point of view, the effect of simultaneous treatment may be lessened than in the case of only lateral and medial treatment.

Physical and psychosocial work-related exposures and the occurrence of disorders of the elbow: A systematic review. APPLIED ERGONOMICS 2023; 108:103952. [PMID: 36493677 DOI: 10.1016/j.apergo.2022.103952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/15/2022] [Accepted: 11/22/2022] [Indexed: 06/17/2023]
Abstract
This systematic review updates a previous systematic review on work-related physical and psychosocial risk factors for elbow disorders. Medline, Embase, Web of Science, Cochrane Central and PsycINFO were searched for studies on associations between work-related physical or psychosocial risk factors and the occurrence of elbow disorders. Two independent reviewers selected eligible studies and assessed risk of bias (RoB). Results of studies were synthesized narratively. We identified 17 new studies and lateral epicondylitis was the most studied disorder (13 studies). Five studies had a prospective cohort design, eight were cross-sectional and four were case-control. Only one study had no items rated as high RoB. Combined physical exposure indicators (e.g. physical exertion combined with elbow movement) were associated with the occurrence of lateral epicondylitis. No other consistent associations were observed for other physical and psychosocial exposures. These results prevent strong conclusions regarding associations between work-related exposures, and the occurrence of elbow disorders.

Open procedure vs. arthroscopic débridement for chronic medial epicondylitis. J Shoulder Elbow Surg 2023; 32:340-347. [PMID: 36279988 DOI: 10.1016/j.jse.2022.09.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 09/15/2022] [Accepted: 09/28/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND This retrospective study compared the outcomes after open and arthroscopic treatment of chronic medial epicondylitis (ME). METHODS The study included 44 elbows in 38 patients: 25 (29-72 years) in the open group and 19 (27-70 years) in the arthroscopy group. The indications for ME surgery were failed conservative therapy for more than 3 months, symptom duration exceeding 6 months, and persistent severe pain. We used radiography, ultrasonography, and magnetic resonance imaging assessments. The clinical assessment included operating time, range of motion, grip strength, visual analog scale (VAS) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and complications. RESULTS The mean follow-up was 20.2 (12-58) months. The mean operating time was significantly longer in the arthroscopy group (32.5 vs. 23.5 minutes; P = .029). In both groups, all outcome measures improved significantly after surgery and there were no significant differences between the DASH scores (preoperative 44.8 vs. 43.9, postoperative 12.5 vs. 13.2), grip strength (preoperative 72.2 vs. 66.8, postoperative 84.8 vs. 83.6), and VAS scores (preoperative 8.5 vs. 8.2, postoperative 1.0 vs. 1.1) in the open and arthroscopy groups. The outcomes were excellent or good in 20 patients (80%) in the open group and 16 (84%) in the arthroscopy group. The only complication was 1 case of transient ulnar neuropathy in the open group. CONCLUSION Open and arthroscopic techniques were very effective and comparable for treating chronic ME. The surgeon can choose either technique for treating chronic ME.

Radiologic evaluation and clinical effect of calcification in medial epicondylitis. J Shoulder Elbow Surg 2022; 31:375-381. [PMID: 34610463 DOI: 10.1016/j.jse.2021.08.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 08/20/2021] [Accepted: 08/29/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Although most radiologic findings of medial epicondylitis (ME) are normal, up to 25% show calcification, and little is known about the clinical relevance of soft-tissue calcification in ME. The purposes of this study were to reveal the characteristics of calcification in ME and to identify their clinical relevance. METHODS This study included 187 patients (222 elbows) with a diagnosis of ME. We classified calcification according to its anatomic location and further evaluated its distribution. Logistic regression analysis was performed to calculate the odds ratios and 95% confidence intervals for possible factors that may affect calcification in ME: age, sex, laterality, hand dominance, visual analog scale (VAS) pain score, Mayo Elbow Performance Score, symptom duration, history of steroid injection, number of steroid injections, concomitant ulnar neuropathy, and treatment method in terms of conservative treatment or surgery. RESULTS Of a total of 222 elbows, 53% (118 of 222 elbows) showed calcification in radiologic findings. The VAS pain score, the number of steroid injections, and concomitant ulnar neuropathy were significantly associated with calcification in ME. Calcification was most commonly identified at the anatomic insertion site of the common flexor tendon (33%), followed by the pronator teres (18%) and the medial collateral ligament (10%). Of the total cases of calcification, 45% were distributed at multiple sites, and age was strongly associated with multiple-site distribution. CONCLUSIONS Calcification in ME was more commonly identified than previously reported and was distributed over a relatively broad area. Calcification was associated with a higher VAS pain score, a history of steroid injection, and combined ulnar neuropathy. The anatomic insertion site of the common flexor tendon most commonly showed calcification, and age was a strong indicator of a broad distribution of calcification.

Magnetic resonance imaging evaluation of patients with clinically diagnosed medial Epicondylitis. Skeletal Radiol 2021; 50:1629-1636. [PMID: 33483771 DOI: 10.1007/s00256-021-03720-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 01/17/2021] [Accepted: 01/18/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE We evaluated magnetic resonance imaging (MRI) findings in patients with clinically diagnosed medial epicondylitis (ME) and determined whether any of the MRI findings correlated with the follow-up pain level after nonoperative treatment. MATERIALS AND METHODS We retrospectively reviewed 83 patients who had undergone elbow MRI examinations for clinically diagnosed ME and who were followed-up for more than 6 months. Five categories of MRI findings were selected for qualitative grading: common flexor tendon (CFT) origin signal changes, ulnar collateral ligament (UCL) insufficiency, ulnar neuritis, bony changes of the medial epicondyle, and calcification. The mean follow-up after MRI examination was 21 months. We performed multivariate regression analysis to analyze whether any of these MRI findings were associated with the follow-up pain level after nonoperative treatment. RESULTS Positive MRI findings included CFT origin signal changes (66%), ulnar neuritis (40%), UCL insufficiency (30%), calcification (27%), and bony changes (18%). Multivariate analysis indicated that CFT origin signal changes were independently associated with the follow-up pain level (β = 3.387; p = 0.004). CONCLUSION In patients with clinically diagnosed ME, MRI demonstrated diverse abnormal findings in the CFT origin, ulnar collateral ligament, ulnar nerve, and bone. Among the findings, the severity CFT origin signal changes, which indicates the severity of tendon degeneration in ME, was associated with the follow-up pain level. This information can be helpful in consulting on the prognosis of nonoperative treatment in patients with clinically diagnosed ME.

Short-term Results of Transcatheter Arterial Embolization for Chronic Medial Epicondylitis Refractory to Conservative Treatment: A Single-Center Retrospective Cohort Study. Cardiovasc Intervent Radiol 2021; 45:197-204. [PMID: 34089076 DOI: 10.1007/s00270-021-02878-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 05/19/2021] [Indexed: 02/03/2023]
Abstract
PURPOSE To evaluate the effectiveness and safety of transcatheter arterial embolization (TAE) for chronic medial epicondylitis (ME) refractory to conservative treatments. MATERIALS AND METHODS This retrospective study included ten patients (14 procedures) who underwent TAE between May of 2018 and April of 2020 to treat chronic ME refractory to conservative treatments for at least 3 months. Imipenem/cilastatin sodium was used in 12 procedures, and quick-soluble gelatin sponge particles were used in the ensuing two procedures as an embolic agent. The visual analogue scale (VAS, 0-10) score and Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH) scores were assessed at baseline and at different post-treatment times (1 day; 1 week; 1, 3, and 6 months; and an open period). The clinical success of the procedure was defined as a decrease of more than 70% in the Quick-DASH scores at 6 months compared to the baseline. RESULTS Clinical success was achieved in 12 of 14 procedures (85.7%). No major complications were observed during the follow-up periods. The mean VAS scores were significantly decreased at 1 day, 1 week, 1 month, 3 months and 6 months (7.6 at baseline vs. 3.6, 3.6, 3.6, 3, and 0.9 after treatment; all P < .01). The mean Quick-DASH scores at baseline decreased significantly at 1 day, 1 week, and at 1, 3, and 6 months after treatment (71.9 vs. 48.5, 44, 37.7, 30.2, and 8.4; all P < .01). These improvements endured in nine patients for up to 12 months after treatment. CONCLUSION TAE effectively and safely relieved pain and promoted functional recovery in chronic ME patients refractory to conservative treatments. TAE may be a feasible treatment option for patients with ME intractable to conservative treatments.

Abstract
Common flexor-pronator tendon injuries and medial epicondylitis can be successfully treated nonoperatively in most cases. Operative treatment is reserved for patients with continued symptoms despite adequate nonoperative treatment or in high-level athletes with complete rupture of the common flexor-pronator tendon. The physical examination and workup of patients with flexor-pronator tendon injuries should focus on related or concomitant pathologies of the medial elbow. The gold standard for surgical treatment of flexor-pronator tendon ruptures or medial epicondylitis includes tendon debridement and reattachment.

Abstract
The pathogenesis of ulnar nerve subluxation and dislocation is widely debated. Upon elbow flexion, the ulnar nerve slips out of the groove for the ulnar nerve, relocates medial or anterior to the medial epicondyle, and returns to its correct anatomical position upon extension. This chronic condition can cause neuritis or neuropathy; however, it has also been suggested that it protects against neuropathy by reducing tension along the nerve. This article reviews the extant literature with the aim of bringing knowledge of the topic into perspective and standardizing terminology.

Clinical outcomes of combined surgical treatment of medial epicondylitis and cubital tunnel syndrome. HAND SURGERY & REHABILITATION 2019; 38:298-301. [PMID: 31404681 DOI: 10.1016/j.hansur.2019.08.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 07/21/2019] [Accepted: 08/06/2019] [Indexed: 11/30/2022]
Abstract
Surgical results for treatment of medial epicondylitis and cubital tunnel syndrome are generally satisfactory when performed alone. However, our experience suggests a combined procedure is associated with inferior outcomes. A retrospective review was conducted of consecutive surgical cases of medial epicondylectomy/debridement and ulnar nerve decompression during a single operation at our institution from March 2008 to February 2017 using CPT codes. Thirty combined procedures were identified in 29 patients. Fourteen patients and 15 elbows returned to clinic for evaluation at average 4.3 years after surgery (8 men, 6 women, mean age 45.1 years). A Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, visual analogue pain scale (VAS), and physical examination were performed. The data was stratified by type of ulnar nerve procedure and analyzed. Three of fifteen elbows underwent in situ ulnar nerve decompression, and twelve of 15 had transposition, five subcutaneous and seven submuscular. The mean DASH score for in situ decompression was significantly higher than that of transposition (68.2 vs. 13.1). The average visual pain score for patients whom underwent in situ decompression was significantly higher than that of those with ulnar nerve transposition (8.0 vs. 1.2). All other physical exam measures demonstrated no significant difference between the two groups. In situ ulnar nerve decompression in the setting of medial epicondylectomy/debridement may be associated with inferior clinical outcomes in comparison to ulnar nerve transposition. Further studies are needed to validate the results of our study and inform management.

Abstract
The aim of this study was to evaluate the diagnostic potential of real-time sonoelastography (RSE) in medial epicondylitis by comparing clinically diagnosed patients and patients without medial elbow pain. From July 2016 to December 2017, gray-scale sonographic findings (swelling, cortical irregularity, hypo-echogenicity, calcification and tear), color Doppler findings (hyperemia) and sonoelastographic findings (elastographic grade on a 3-point visual scale and strain ratio from two regions of interest) for 63 elbows of 56 patients were compared. Twenty-four patients with 29 imaged elbows were clinically diagnosed with medial epicondylitis, and 32 patients with 34 imaged elbows had no medial elbow pain. Cortical irregularity, hypo-echogenicity, calcification, elastographic grade and strain ratio revealed significant differences (p < 0.05). Among these, strain ratio had the highest diagnostic performance (area under the curve: 0.985). Real-time sonoelastography, which can obtain both elastographic grade and strain ratio, is valuable as a supplementary tool in the diagnosis of medial epicondylitis.

Abstract
BACKGROUND Angiofibroblastic changes of a musculotendinous origin at the medial epicondyle characterize medial epicondylitis of the elbow. Although nonsurgical treatment is the primary approach for medial epicondylitis, surgical treatment should be considered when conservative therapy fails. This study reports the results of surgical treatment of medial epicondylitis monitored for more than 5 years. METHODS This study included 55 patients with 63 cases of medial epicondylitis between 2000 and 2010. The conservative treatment periods lasted for a minimum of 1 year, and steroid injections were administered more than twice before surgery. One surgeon conducted the surgical procedures. The Nirschl and Pettrone grades, visual analog scale (VAS) scores, Disabilities of the Arm, Shoulder and Hand (DASH) scores, Mayo Elbow Performance scores, and grip strengths were analyzed. Statistical analyses were performed using paired t tests. RESULTS The mean VAS score improved from 8.5 to 2.4 (P <.001). Nirschl and Pettrone grades rated 43% (27 elbows) as excellent and 51% (32 elbows) as good. The Mayo Elbow Performance scores improved from 72 to 88 (P <.001) and DASH scores from 57 to 23 (P <.001). The mean grip strength of the affected side improved from 30 to 43 lb (P <.001). The mean time required to return to work and exercise was 2.8 months and 4.8 months, respectively. One case of heterotrophic ossification, which had no functional instability afterward, was seen. CONCLUSION The results indicate that surgical treatment of medial epicondylitis could be an effective and safe treatment when conservative treatment fails.

Abstract
BACKGROUND Medial epicondylitis of the elbow, an overuse injury characterized by angiofibroblastic tendinosis of the common flexor-pronator origin, generally responds to nonoperative treatment. Refractory cases may require surgical débridement and repair. This study discusses physical examination and imaging findings and an updated surgical technique used in patients with recalcitrant medial epicondylitis. METHODS The surgical records of 60 patients with refractory medial epicondylitis were reviewed. All received a course of nonoperative care. After 3 to 6 months of failed therapy, imaging was obtained, and surgical intervention was offered when indicated. This open procedure consisted of thorough débridement with repair and restoration of the flexor-pronator origin, using a suture anchor. Accelerated rehabilitation, emphasizing early motion, was used. One-year follow-ups were obtained. The Mayo Elbow Performance Score was calculated preoperatively and postoperatively. RESULTS Pronation weakness at 90° was a critical physical examination finding. Preoperative magnetic resonance images demonstrated pathologic partial tearing at the flexor-pronator origin. Ulnar neuritis was addressed in 20%. Postoperatively, the Mayo Elbow Performance Score significantly increased (preoperatively, 58 ± 7.7; postoperatively, 88 ± 7.8; P = 5.6E-34), and pain significantly decreased (preoperatively, 2.2 ± 0.3; postoperatively, 0.6 ± 0.5; P = 3.8E-33). There was one retear in a patient noncompliant with the postoperative protocol. He responded positively to reoperation. CONCLUSION Identification of weakness on pronation is a reliable physical examination finding for determining clinically significant pathologic changes in patients with medial epicondylitis. Débridement with restoration of the flexor-pronator origin is an efficacious procedure. In this large series of patients, surgical repair with aggressive rehabilitation was shown to be reliable and safe in restoring function and relieving pain in recalcitrant cases of medial epicondylitis.

Abstract
Overuse injuries of the lateral and medial elbow are common in sport, recreational activities, and occupational endeavors. They are commonly diagnosed as lateral and medial epicondylitis; however, the pathophysiology of these disorders demonstrates a lack of inflammation. Instead, angiofibroblastic degeneration is present, referred to as tendinosis. As such, a more appropriate terminology for these conditions is epicondylosis. This is a clinical diagnosis, and further investigations are only performed to rule out other clinical entities after conventional therapy has failed. Yet, most patients respond to conservative measures with physical therapy and counterforce bracing. Corticosteroid injections are effective for short-term pain control but have not demonstrated long-term benefit.

Abstract
OBJECTIVE To evaluate the effectiveness of initial extracorporeal shock wave therapy (ESWT) for patients newly diagnosed with lateral or medial epicondylitis, compared to local steroid injection. METHOD An analysis was conducted of twenty-two patients who were newly confirmed as lateral or medial epicondylitis through medical history and physical examination. The ESWT group (n=12) was treated once a week for 3 weeks using low energy (0.06-0.12 mJ/mm(2), 2,000 shocks), while the local steroid injection group (n=10) was treated once with triamcinolone 10 mg mixed with 1% lidocaine solution. Nirschl score and 100 point score were assessed before and after the treatments of 1st, 2nd, 4th and 8th week. And Roles and Maudsley score was assessed one and eight weeks after the treatments. RESULTS Both groups showed significant improvement in Nirschl score and 100 point score during the entire period. The local steroid injection group improved more in Nirschl score at the first week and in 100 point score at the first 2 weeks, compared to those of the ESWT group. But the proportion of excellent and good grades of Roles and Maudsley score in the ESWT group increased more than that of local steroid injection group by the final 8th week. CONCLUSION The ESWT group improved as much as the local steroid injection group as treatment for medial and lateral epicondylitis. Therefore, ESWT can be a useful treatment option in patients for whom local steroid injection is difficult.

Abstract
Background This study examined the clinical results of surgical treatment using a mini-open muscle resection procedure under local anesthesia for intractable lateral or medial epicondylitis. Methods Forty two elbows (41 patients) were treated surgically for lateral or medial epicondylitis. The indication for surgery was refractory pain after six months of conservative treatment, or a history of more than three local injections of steroid, or severe functional impairment in the occupational activities. The treatment results were assessed in terms of the pain using the visual analogue scale (VAS), Roles & Maudsley score, and Nirschl & Pettrone grade. Results The preoperative VAS scores of pain were an average of 5.36 at rest, 6.44 at daily activities, and 8.2 at sports or occupational activities. After surgery, the VAS scores improved significantly (p < 0.01): 0.3 at rest, 1.46 at daily activities, and 2.21 at sports or occupational activities. The preoperative Roles & Maudsley score was acceptable in 6 cases, and poor in 36 cases, which was changed to excellent in 23 cases, good in 16 cases, acceptable in 3 cases after surgery. According to the grading system by Nirschl & Pettrone, 23 cases were excellent, 18 cases were good, and the remaining 1 case was fair. Overall, 41 cases (97.6%) achieved satisfactory results. Postoperative complications were encountered in three cases. Subcutaneous seroma due to the leakage of joint fluid in two patients was managed by additional surgery and suction drainage, and resulted in a satisfactory outcome. One patient complained of continuous pain on occupational activity, but her pain at rest was improved greatly. Conclusions The mini-open muscle resection procedure under local anesthesia appears to be one of effective methods for intractable lateral or medial epicondylitis.
