Abstract
Background Arthroscopic electrothermal treatment of low-grade Geissler's scapholunate interosseous ligament (SLIL) tears has shown clinical benefit at short-term follow-up. Questions/Purpose This study aims to evaluate the long-term functional outcomes in patients undergoing this treatment. Patients and Methods A retrospective review of all patients treated between 2005 and 2013 was performed. Patients were excluded with less than 5 years of follow-up, the presence of static SLIL injuries, prior wrist surgery, and concomitant denervation. Symptom resolution, return to activity, postoperative complications, range of motion, grip strength, and subsequent treatment were recorded. Each patient completed Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Modified Mayo Wrist (MMW), and Patient-Rated Wrist Evaluation (PRWE) questionnaires. Results Nine patients underwent treatment for Geissler's grade I, II, and III SLIL injuries with a mean 7 years (range: 5-11 years) of follow-up. Mean grip strength was 99% of the nonsurgical extremity. Wrist motion was near symmetric with a mean of 76 (±14), 74 (±8), 21 (±13), and 40 degrees (±13) for wrist flexion, extension, radial deviation, and ulnar deviation. QuickDASH improved significantly by a mean 39 points (50 (preoperative)-11 [postoperative], p = 0.009). Postoperative MMW and PRWE scores were 83 and 14, respectively. Visual analog scale (VAS) score was 1.4. A total of 90% was returned to their preinjury level of function or higher. Conclusions Arthroscopic electrothermal treatment of low-grade Geissler's SLIL tears demonstrates excellent objective and subjective outcomes at a minimum 5-year follow-up, providing evidence that this is an effective, safe, and, most importantly, durable-therapeutic modality. Level of Evidence This is a Level IV, case series study.

Electrothermal arthroscopic capsulorrhaphy: old technology, new evidence. A multicenter randomized clinical trial. J Shoulder Elbow Surg 2014; 23:1171-80.

Abstract
BACKGROUND Radiofrequency technology for shoulder instability was rapidly adopted despite limited clinical evidence and a poor understanding of its indications. Reports of serious adverse events followed, leading to its abandonment. This paper presents findings from a multicenter randomized clinical trial evaluating the safety and efficacy of electrothermal arthroscopic capsulorrhaphy (ETAC) compared with open inferior capsular shift (ICS) and reviews the role of randomized trials in adopting new technology. METHODS Patients (>14 years) diagnosed with multidirectional instability or multidirectional laxity with anteroinferior instability and failed nonoperative treatment were enrolled. Patients with bone lesions or labral, biceps anchor, or full-thickness rotator cuff tears were excluded intraoperatively. Outcomes included Western Ontario Shoulder Instability Index, function and recurrent instability at 2 years postoperatively, and surgical times. RESULTS Fifty-four subjects (mean age, 23 years; 37 women) were randomized to ETAC (n = 28) or open ICS (n = 26). The groups were comparable at baseline, except for external rotation at the side. At 2 years postoperatively, there were no statistically or clinically significant differences between groups for the Western Ontario Shoulder Instability Index (P = .71), American Shoulder and Elbow Surgeons score (P = .43), Constant score (P = .43), and active range of motion. Recurrent instability was not statistically different (ETAC, 2; open, 4; P = .41). ETAC (23 minutes) was significantly shorter than open ICS (59 minutes) (P < .01) surgery. Three subjects (1 ETAC, 2 open) had stiff shoulders. CONCLUSIONS At 2 years postoperatively, quality of life and functional outcomes between groups were not clinically different. ETAC had fewer complications and episodes of recurrence compared with open surgery. This evidence reinforces the need to critically evaluate new technology before widespread clinical use.

Abstract
UNLABELLED Thermal capsular shrinkage was popular for the treatment of shoulder instability, despite a paucity of outcomes data in the literature defining the indications for this procedure or supporting its long-term efficacy. The purpose of this study was to perform a clinical evaluation of radiofrequency thermal capsular shrinkage for the treatment of shoulder instability, with a minimum 2-year follow-up. From 1999 to 2001, 101 consecutive patients with mild to moderate shoulder instability underwent shoulder stabilization surgery with thermal capsular shrinkage using a monopolar radiofrequency device. Follow-up included a subjective outcome questionnaire, discussion of pain, instability, and activity level. Mean follow-up was 3.3 years (range 2.0-4.7 years). The thermal capsular shrinkage procedure failed due to instability and/or pain in 31% of shoulders at a mean time of 39 months. In patients with unidirectional anterior instability and those with concomitant labral repair, the procedure proved effective. Patients with multidirectional instability had moderate success. In contrast, four of five patients with isolated posterior instability failed. Thermal capsular shrinkage has been advocated for the treatment of shoulder instability, particularly mild to moderate capsular laxity. The ease of the procedure makes it attractive. However, our retrospective review revealed an overall failure rate of 31% in 80 patients with 2-year minimum follow-up. This mid- to long-term cohort study adds to the literature lacking support for thermal capsulorrhaphy in general, particularly posterior instability.

Abstract
HYPOTHESIS Chondrolysis can be a devastating complication of shoulder arthroscopy. We undertook a review of the 100 cases reported in the English language to test the hypothesis that common factors could be identified and that the identification of these factors could suggest strategies for avoiding this complication. MATERIALS AND METHODS We systematically reviewed the English language literature and identified 16 articles reporting 100 shoulders in which postsurgical glenohumeral chondrolysis had developed. RESULTS The average reported patient age was 27 +/- 11 years at the time of surgery; 35 were women. The most common indications for surgery were instability (n = 68) and superior labrum anteroposterior lesions (n = 17). In 59 cases, chondrolysis was reported to be associated with the use of intra-articular pain pumps. The infusate was known to include bupivacaine in 50 shoulders and lidocaine in 2. Radiofrequency capsulorrhaphy was performed in 2 shoulders. DISCUSSION Fifty-nine percent of the reported cases of glenohumeral chondrolysis occurred with the combination of arthroscopic surgery and postarthroscopy infusion of local anesthetic. The arthroscopic operations observed with chondrolysis were not limited to stabilization procedures, and the infused anesthetic was not limited to bupivacaine. CONCLUSION In that postoperative infusion of local anesthetic and radiofrequency may not be essential to the success of shoulder arthroscopy, surgeons may wish to consider the possible risks of their use.

Abstract
The function of the glenohumeral capsule has typically been evaluated by isolating several discrete, ligamentous regions during experimental and computational investigations. However, recent data suggests that the regions of the glenohumeral capsule have significant interactions and function multiaxially. Therefore, examining the function of the inferior glenohumeral ligament as a discrete structure may not be appropriate. The objective of this work was to validate the predicted strain distribution and deformed shape of the inferior glenohumeral ligament using experimental data for two subject-specific finite element models: (1) a continuous model including all capsular regions, and (2) a discrete model including only the inferior glenohumeral ligament. The distribution of maximum principal strain and deformed shape of the glenohumeral capsule was determined for a cadaveric shoulder in a joint position frequently associated with dislocation (60 degrees of glenohumeral abduction, 52 degrees of external rotation, and a 25 N anterior load applied to the humerus). The experimental kinematics were then applied to the two finite element models constructed from the geometry and material properties from the same cadaveric shoulder and the predicted strain distributions and deformed shapes were determined. For the continuous model, the average difference between predicted strains and experimental strains was less than 5%. The predicted deformed shape was also similar to experimental data, with the anterior band of the inferior glenohumeral ligament clearly wrapped around the humeral head. In contrast, large differences existed between the strains predicted by the discrete model when compared to the experimental strains for this joint position (average difference from experimental data was 20%). In addition, the predicted deformed shape of the inferior glenohumeral ligament did not wrap around the humeral head. These differences may be attributed to neglecting the complex interactions between the anterior band of the inferior glenohumeral ligament with the neighboring capsular regions. Thus, the glenohumeral capsule should not be evaluated as several discrete structures. Rather, it should be evaluated as a single sheet of fibrous tissue.

Abstract
Inconclusive findings regarding the collagen fiber architecture and the material properties of the glenohumeral capsule make it unclear whether the material symmetry of the glenohumeral capsule is isotropic or anisotropic. The overall objective of this work was to use a combined experimental and computational protocol to characterize the mechanical properties of the axillary pouch of the glenohumeral capsule and to determine the appropriate material symmetry. Two perpendicular tensile and finite simple shear deformations were applied to a series of tissue samples from the axillary pouch of the glenohumeral capsule. An inverse finite element optimization routine was then used to determine the material coefficients for an isotropic hyperelastic constitutive model by simulating the experimental conditions. There were no significant differences between the material coefficients obtained from the two perpendicular tensile deformations or finite simple shear deformations. Furthermore, stress-stretch relationships predicted by utilizing the material coefficients from one direction were able to predict the responses of the same tissue sample in the perpendicular direction. These similarities between the longitudinal and transverse material behaviors of the tissue imply that the capsule may be considered an isotropic material. However, differences did exist between the material coefficients obtained from the tensile and shear loading conditions. Therefore, a more advanced constitutive model is needed to predict both the tensile and shear responses of the material.

Abstract
INTRODUCTION Anterior dislocation of the shoulder is commonly seen in accident and emergency (A&E) and trauma clinics. In this article, we review the existing literature on the injury and the recent trends in management. MATERIALS AND METHODS We have discussed this condition with our colleagues and performed a Medline search ('anterior shoulder dislocation') of the relevant papers. We also describe key historical publications and recent developments regarding immobilisation of the joint. RESULTS Management decisions regarding this condition continue to vary between units, especially for recurrent and posterior dislocation. This paper lays some emphasis on the choice of analgesic agent when attempting shoulder reduction in the A&E setting. A summary of the data from our own department has provided a graphical representation of the classical age and sex distribution for this condition. CONCLUSIONS Shoulder dislocation is a common injury. Delays in diagnosis remain the single biggest obstacle to optimum results in this group of patients. A significant proportion will require eventual surgery and up to a third of these patients will go on to develop long-term shoulder arthritis. Even patients who have experienced a single episode of dislocation may go on to develop long-term sequelae.

Abstract
BACKGROUND Reports of glenohumeral chondrolysis following arthroscopy have raised concern about the deleterious effects that thermal devices may have on articular cartilage. The purpose of this study was to investigate the effects of flow and duration of treatment with a thermal device on temperatures within cadaveric glenohumeral joint specimens. It was hypothesized that the use of a thermal device during surgery increases the temperature of fluid within the joint to >45 degrees C, which has been shown to cause chondrocyte death. METHODS Temperature was measured at four locations within ten cadaver shoulder joints. Eight heating trials were performed on each cadaver shoulder to test three variables: the method of heating (continuous or intermittent), the fluid-pump flow rate (no flow, 50% flow, or 100% flow), and the location of the radiofrequency probe (the radiofrequency energy was either applied directly to anterior capsular tissue in a paintbrush pattern or held adjacent to the glenoid without tissue contact). RESULTS Temperatures of >45 degrees C occurred in every trial. The average maximum temperatures in all no-flow conditions were significantly higher than those in the trials with flow. Higher temperatures were measured by the anterior probe in all trials. When the heating had been applied adjacent to the glenoid, without tissue contact, the time needed to cool to a safe temperature was significantly longer in the no-flow states (average, 140.5 seconds) than it was in the 50% flow states (average, 12.5 seconds) or the 100% flow states (average, 8.5 seconds). CONCLUSIONS Use of a thermal probe during arthroscopy may cause joint fluid temperatures to reach levels high enough to cause chondrocyte death. Maintaining adequate fluid-pump flow rates may help to lower joint fluid temperatures and protect articular cartilage.

Abstract
Chondrolysis following shoulder arthroscopy is a devastating complication, often seen in young patients. After nonoperative measures have been exhausted, there are few treatment options available that reliably improve pain and function. The purpose of this study is to examine the intra-operative findings, radiographic features, and clinical outcomes of a series of patients with chondrolysis following arthroscopic surgery managed with a total shoulder arthroplasty. A retrospective review was performed on 11 patients (average age 39) with shoulder chondrolysis following arthroscopy. Attention was focused on review of the index arthroscopy, radiographs, and functional outcome scores prior to total shoulder arthroplasty, as well as intra-operative cultures, histology, radiographs, and functional outcomes from most recent follow-up. All patients were treated with total shoulder arthroplasty at an average of 26 months after the index arthroscopy. Preoperative and postoperative radiographs were reviewed, and outcomes were compared using validated measurements. Statistically significant improvements in shoulder abduction (89 degrees -123 degrees , P = .027), external rotation (26 degrees -48 degrees , P = .037), total ASES scores (30-77.5, P = .0039), and SST scores (3-8, P = .0078) were noted. Ten patients subjectively rated their outcomes as good or excellent, with 1 as satisfactory. Chondrolysis after shoulder arthroscopy has a rapid clinical progression and is likely multifactorial in etiology. Early results of total shoulder arthroplasty show an opportunity for improvements in pain and function; however, progressive glenoid radiolucencies may develop in these patients.

Abstract
Midcarpal instability is an uncommon problem in which deficient static and dynamic wrist stabilisers cause sudden, uncontrolled movement of the proximal carpal row. We studied 15 wrists prospectively in 13 patients who underwent arthroscopic thermal capsulorrhaphy for palmar midcarpal instability. Capsulorrhaphy was performed using standard wrist arthroscopic techniques and a small diameter monopolar radiofrequency probe. One hundred percent follow-up was achieved at a mean of 42 (range 14 - 67) months. With regards to instability, all wrists showed improvement or resolution of instability. Functional improvement was confirmed by an improvement in the mean DASH score from 38 pre-operatively to 17 at final follow-up. Our early results show that thermal capsulorrhaphy is effective in reducing the instability symptoms of palmar midcarpal instability.

Abstract
Glenohumeral chondrolysis is a rare but devastating complication that can occur after shoulder arthroscopy and thermal capsulorrhaphy. We retrospectively reviewed the medical records and imaging studies of 8 patients in whom glenohumeral chondrolysis developed after shoulder arthroscopy in which thermal energy was used. Of the 8 patients, 5 had previous thermal capsulorrhaphy for the diagnosis of instability. Two patients were diagnosed with instability with associated labral tears and underwent labral repair with thermal capsular shrinkage. One patient was diagnosed with a labral tear and underwent labral debridement with an extensive glenohumeral synovectomy via a thermal probe. No patients had evidence of chondral damage at their index arthroscopy, and none received postoperative pain pumps. In all patients, radiographic evidence of chondrolysis developed and repeat arthroscopy was performed to confirm the diagnosis. Open surgical stabilization has not been known to have this complication, and it is speculated that heating of the joint fluid at the time of arthroscopy from any source plays a role in cartilage death. Further studies are warranted to determine whether adequate outflow during shoulder arthroscopy where the fluid volume is relatively small will aid in avoiding complications associated with the use of heat sources.

Abstract
BACKGROUND All-arthroscopic rotator cuff repair is becoming more commonly performed with recent improvements in implants, instrumentation, and techniques. This study evaluated the influence of different training resources for surgeons performing this procedure. METHODS A twenty-eight-item survey was created to evaluate the methods by which orthopaedic surgeons are trained in the skill of all-arthroscopic rotator cuff repair. We selected 2455 surgeons from the American Academy of Orthopaedic Surgeons web site who indicated that they performed shoulder surgery, arthroscopic surgery, and/or sports medicine as part of their practice. Using a 5-point Likert scale, the respondents rated the relative importance of different training resources, including the completion of a sports medicine or shoulder surgery fellowship, attendance at instructional courses, and practice on shoulder models, in contributing to their ability to perform arthroscopic rotator cuff repair. RESULTS Of the 2455 surveys sent, 1076 were returned (a response rate of 43.8%). Significantly more surgeons indicated that they performed arthroscopic repairs for a 2-cm tear compared with a 5-cm tear (p < 0.001). A younger age, higher volume of shoulder arthroscopies, and higher volume of rotator cuff repairs were all associated with significantly higher rates of preference for all-arthroscopic repairs compared with other types of repairs (p < 0.001). Compared with surgeons who received training in shoulder surgery during residency only, surgeons who had completed either shoulder or sports medicine fellowships were more likely to perform all-arthroscopic repairs. When ranking the relative importance of resources in the training for all-arthroscopic repair, the overall Likert scale scores were highest for a sports medicine fellowship (3.49), hands-on instructional courses (3.33), and practice in an arthroscopy laboratory on cadaver specimens (3.22). Likert scores were lowest for residency training (2.02), practice on artificial shoulder models (2.13), and Internet resources (2.25). CONCLUSION The information from this survey may be used to direct the continually evolving training of surgeons in arthroscopic rotator cuff repairs.

Abstract
PURPOSE To present the early results of arthroscopic debridement and thermal shrinkage using radiofrequency probes for partial (Geissler grades I and II) scapholunate (SL) interosseous ligament injuries of the wrist. METHODS Sixteen patients with a mean age of 34 years (range, 18-54 y) presenting with chronic dorsoradial wrist pain unresponsive to initial conservative treatment for a mean period of 12 weeks were included in this study. No patient showed radiologic signs of static dissociation (SL interval, <3.5 mm; mean SL angle, 49 degrees ) before surgery. Diagnostic arthroscopy showed a partial SL tear in 14 patients and redundancy of the ligament in 2. Partial SL tears involved the membranous (proximal) and volar part of the ligament. All lesions were debrided and treated with thermal shrinkage using a bipolar radiofrequency probe. RESULTS The mean follow-up period was 19 months (range, 9-34 mo). Fourteen patients experienced substantial pain relief whereas in 2 the pain remained unchanged. Eight patients were completely pain free. The mean flexion-extension arc was 142 degrees and the mean grip strength was 78% that of the unaffected side. No patient showed radiologic signs of arthritis or static or dynamic instability after surgery (SL interval remained <3.5 mm; mean SL angle, 53 degrees ). Based on the modified Mayo wrist score there were 8 excellent, 6 good, 1 fair, and 1 poor result. CONCLUSIONS Partial SL ligament tears can be a source of radial-sided wrist pain. Scapholunate ligament debridement and thermal shrinkage effectively provided pain relief for most of the patients treated. Stability was maintained radiographically. No complications were noted from the use of radiofrequency probes. These reasonably favorable short-term results should be viewed cautiously. A longer follow-up study is necessary to determine the ultimate efficacy of this procedure.
