Vij N, Liu JN, Amin N. Radiofrequency in arthroscopic shoulder surgery: a systematic review. Clin Shoulder Elb 2023; 26:423-437. [PMID: 36330719 DOI: 10.5397/cise.2022.01067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 09/16/2022] [Indexed: 06/16/2023] Open
Abstract
BACKGROUND Radiofrequency has seen an increase in use in orthopedics including cartilage lesion debridement in the hip and knee as well as many applications in arthroscopic shoulder surgery. The purpose of this systematic review is to evaluate the safety and usage of radiofrequency in the shoulder. METHODS This systematic review was registered with PROSPERO (international registry) and followed the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines. Embase and PubMed were searched using: "shoulder," "rotator cuff," "biceps," "acromion" AND "monopolar," "bipolar," "ablation," "coblation," and "radiofrequency ablation." The title and abstract review were performed independently. Any discrepancies were addressed through open discussion. RESULTS A total of 63 studies were included. Radiofrequency is currently utilized in impingement syndrome, fracture fixation, instability, nerve injury, adhesive capsulitis, postoperative stiffness, and rotator cuff disease. Adverse events, namely superficial burns, are limited to case reports and case series, with higher-level evidence demonstrating safe use when used below the temperature threshold. Bipolar radiofrequency may decrease operative time and decrease the cost per case. CONCLUSIONS Shoulder radiofrequency has a wide scope of application in various shoulder pathologies. Shoulder radiofrequency is safe; however, requires practitioners to be cognizant of the potential for thermal burn injuries. Bipolar radiofrequency may represent a more efficacious and economic treatment modality. Safety precautions have been executed by institutions to cut down patient complications from shoulder radiofrequency. Future research is required to determine what measures can be taken to further minimize the risk of thermal burns.

Abstract
PURPOSE To explore the temperature threshold of thermal damage to growth plates. METHODS Nine rabbits were divided into three groups for femoral ablation, exposing the growth plate to different temperatures (T1 = 43-45 °C; T2 = 46-48 °C; T3 = 49-51 °C). After 5 weeks, the changes in the femurs were assessed by macroscopic images, micro-CT, haematoxylin and eosin staining, and immunohistochemistry of Col2a1 (type II collagen). At the cellular level, rabbit epiphyseal chondrocytes were exposed to 37 °C, 44 °C, 47 °C and 50 °C for 5 min. Then, proliferation and chondrogenic differentiation were detected. RESULTS The rabbits in the T2 and T3 groups developed length discrepancies and axial deviations of femurs, abnormal newly formed bone in the marrow cavity, disorganized growth plates and decreased Col2a1 expression. At the cellular level, the cells exposed to 47 °C and 50 °C for 5 min showed decreased viability, increased apoptosis, decreased extracellular matrix synthesis and decreased matrix mineralization. However, the changes in rabbits in the T1 group and cells at 44 °C did not show a significant difference. CONCLUSION The ablation of growth plates at temperatures above 45 °C for 5 min results in decreased chondrocyte viability and disorganized growth plates, leading to growth disturbances. Further studies are warranted to confirm these promising initial results.

Abstract
Background This study aimed to evaluate the response rate to arthroscopic release treatment in adhesive capsulitis of the shoulder (ACS) for patients with refractory to conservative treatment. Methods In this retrospective study, 51 patients (age mean, 49.1±5.6 years) with unilateral adherent capsule underwent arthroscopic releasing surgery for the shoulder capsule. Etiologies of the ACS in 30 patients were idiopathic: 10 patients were affected after surgery and 11 patients following trauma. The patients were evaluated in terms of shoulder function, satisfaction rate, pain intensity, and joint range of motion (ROM) based on a Constant score, a Simple Shoulder Test, the visual analog scale, and four movements, respectively. Results The mean Constant score before surgery was 48.2±3.5 and reached 74.4±6 and 77.0±6.3 at 6 months and the final follow-up, respectively (p<0.001). The mean scores of pain intensity, a Simple Shoulder Test, and ROM showed significant improvement at all follow-ups (p<0.001). Sex, age, and diabetes did not have any significant effect on patient recovery. However, patients who experienced ACS after surgery had poorer results than others at all follow-up points. Conclusions Arthroscopic releasing surgery of the shoulder in patients with ACS refractory to conservative treatment produces rare complications and an effective injury response. It seems that patients suffering ACS following surgery have a weaker response to the treatment.

Abstract
Purpose To investigate the occurrence of heat-related complications from radiofrequency and electrocautery devices in patients undergoing arthroscopic surgery. Methods A systematic review was performed using the PubMed/Medline, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane databases, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All studies reporting complications after arthroscopy using electrosurgery devices were included. Only English- and Dutch-language articles were included. Basic science/nonclinical studies/human cadaveric studies and animal studies were excluded. Article selection was performed by 2 separate reviewers. Interobserver agreement of the selection procedure was determined by Cohen’s kappa. All included articles were critically appraised using an adapted version of the ROBINS-I tool. Results Twenty-five studies were included in this systematic review. A total of 309 cases of heat-related complications were identified. Chondrolysis was present in 45 cases and dermal burns in 15 cases. Axillary nerve injuries were reported in 197 cases of arthroscopic adhesive capsulitis release. However, it was unclear whether these injuries were directly related to the overheating of the arthroscopic fluid. No one specific risk factor for thermal complications was identified, but related factors included the leakage of the arthroscopy fluid, use of a thermal device continuously for a long period of time, proximity of the thermal device to the tissue, intra-articular local anesthetic injection or the use of intra-articular pain pumps, and certain surgical procedures, such as thermal capsulorrhaphy, capsular release, and synovectomy. Conclusions The most common heat-related complications in arthroscopy are dermal burns and chondrolysis. Risk factors include leakage of arthroscopy fluid, use of a thermal device, intra-articular anesthetics/pain pumps, and performing specific surgical procedures. Level of Evidence Systematic review of level III-IV studies.

Abstract
Background: Radiofrequency ablation is commonly used in arthroscopic rotator cuff repair (RCR). New technology devices incorporating a plasma bubble may generate lower intra-articular temperatures and be more efficient. Purpose: To compare a plasma ablation device with a standard ablation device in arthroscopic RCR to determine which system is superior in terms of intra-articular heat generation and diathermy efficiency. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: This was a single-center randomized controlled trial. The inclusion criteria were adult patients undergoing primary RCR. Patients were randomized preoperatively to the standard ablation group (n = 20) or plasma ablation group (n = 20). A thermometer was inserted into the shoulder joint during surgery, and the temperature, surgery, and diathermy times of radiofrequency ablation were measured continually. Results: No significant differences were found between the standard ablation group and plasma ablation group for maximum temperature (38.20°C and 39.38°C, respectively; P = .433), mean temperature (31.66°C and 30.64°C, respectively; P = .757), minimum temperature (21.83°C and 23.45°C, respectively; P = .584), and baseline temperature (28.49°C and 29.94°C, respectively; P = .379). Similarly, no significant differences were found for surgery time (74 and 75 minutes, respectively; P = .866) and diathermy time (10 minutes for both; P = .678). Seven patients registered transient high temperatures greater than 45°C. Conclusion: There was no difference between plasma ablation and standard ablation in terms of intra-articular temperature in the joint and diathermy efficiency. Transient high intra-articular temperatures occurred in both groups. Registration: ACTRN1261300056970 (Australian New Zealand Clinical Trials Registry).

Abstract
Background Radio frequency ablation devices have found a widespread application in arthroscopic surgery. However, recent publications report about elevated temperatures, which may cause damage to the capsular tissue and especially to chondrocytes. The purpose of this study was the investigation of the maximum temperatures that occur in the ankle joint with the use of a commercially available radio frequency ablation device. Methods Six formalin-fixed cadaver ankle specimens were used for this study. The radio frequency device was applied for 120 s to remove tissue. Intra-articular temperatures were logged every second for 120 s at a distance of 3, 5 and 10 mm from the tip of the radio frequency device. The irrigation fluid flow was controlled by setting the inflow pressure to 10 mmHg, 25 mmHg, 50 mmHg and 100 mmHg, respectively. The controller unit voltage setting was set to 1, 5 and 9. Results Maximum temperatures exceeding 50 °C/122 °F were observed for all combinations of parameters, except for those with a pressure of 100 mmHg pressure. The main critical variable is the pressure setting, which is highly significant. The controller unit voltage setting showed no effect on the temperature measurements. The highest temperature was 102.7 °C/215.6 °F measured for an irrigation flow of 10 mmHg. The shortest time span to exceed 50 °C/122 °F was 3 s. Conclusion In order to avoid temperatures exceeding 50 °C/122 °F in the use of radio frequency devices in arthroscopic surgeries of the ankle joint, it is recommended to use a high irrigation flow by setting the pressure difference across the ankle joint as high as feasible. Even short intervals of a low irrigation flow may lead to critical temperatures above 50 °C/122 °F. Level of Evidence Level II, diagnostic study.

Abstract
The manifestation of glenohumeral arthritis in the young adult is a devastating occurrence that can be difficult to manage. This review details the many underlying etiologies including genetic causes, congenital abnormalities, glenohumeral instability, posttraumatic lesions, postcapsulorraphy arthropathy, osteonecrosis, intraarticular pain pump postoperative use, radiofrequency/thermal capsulorraphy treatments, septic arthritis/infection, and inflammatory arthropathies. Although each of these potential causes have been well-studied, their contributions to the development of glenohumeral arthritis in the young person has not been described extensively.

Abstract
PURPOSE To present the clinical results of arthroscopic extended rotator interval release with a stretching program for treating refractory adhesive capsulitis. STUDY DESIGN Case series; level of evidence, 4. METHODS Arthroscopy-assisted extended rotator interval tissue release including anterior capsular was performed in 26 patients with refractory adhesive capsulitis. All rotator interval tissues, except the medial sling of the biceps, were excised and the excursion of the subscapularis tendon was restored and freely mobilized. The preoperative mean passive forward flexion was 101°, whereas external rotation at the side was 10°. Patients were followed for a minimum of 2 years and their visual analog scale for pain, muscle power, range of motion, Constant score, modified American Shoulder and Elbow Surgeons Shoulder Evaluation Form score, and modified University of California at Los Angeles score were recorded. RESULTS Visual pain scale and the aforementioned clinical scores improved postoperatively. The patients exhibited a significant postoperative difference in forward flexion, external rotation, and internal rotation. Postoperative mean passive forward flexion was 172°, whereas external rotation at the side was 58°. There was no difference in the muscle power postoperatively including abduction, internal rotation, and external rotation. CONCLUSIONS Our study revealed satisfactory subjective and objective clinical results after a 2-year follow-up. Arthroscopy-assisted extended rotator interval release with a stretching program could be an alternative treatment for refractory adhesive capsulitis.

Abstract
OBJECTIVE To evaluate the results of arthroscopic releases performed in patients with adhesive capsulitis refractory to conservative treatment. METHODS This was a retrospective study, conducted between 1996 and 2012, which included 56 shoulders (52 patients) that underwent surgery; 38 were female, and 28 had the dominant side affected. The mean age was 51 (29-73) years. The mean follow-up was 65 (12-168) months and the mean preoperative time was 8.9 (2-24) months. According to Zukermann's classification, 23 cases were considered primary and 33 secondary. With the patient in the lateral decubitus position, circumferential release of the joint capsule was performed: joint debridement; rotator interval opening; coracohumeral ligament release; anterior, posterior, inferior, and finally antero-inferior capsulotomy. A subscapularis tenotomy was performed when necessary. All patients underwent intense physical therapy in the immediate postoperative period. In 33 shoulders, an interscalene catheter was implanted for anesthetic infusion. Functional results were evaluated by the UCLA criteria. RESULTS Improved range of motion was observed: mean increase of 45° of elevation, 41° of external rotation and eight vertebral levels of medial rotation. According to the UCLA score excellent results were obtained in 25 (45%) patients; good, in 24 (45%); fair, in two (3%); and poor, in two (7%). Patients who had undergone inferior capsulotomy achieved better results. Only 8.8% of patients who used the anesthetic infusion catheter underwent postoperative manipulation. Seven patients had complications. CONCLUSION There was improvement in pain and range of motion. Inferior capsulotomy leads to better results. The use of the interscalene infusion catheter reduces the number of re-approaches.

Abstract
A frozen shoulder is a common cause of shoulder pain and stiffness. The etiology and pathology of frozen shoulders is not fully understood yet. Frozen shoulder is characterized by a decrease in intra-articular volume and capsular compliance. This can lead to significant limitations in daily life. The majority of the patients can be treated conservatively, with functional recovery to be expected in two to three years. However, if conservative treatment fails, manipulation under anaesthesia and arthroscopic capsular release can both be considered as appropriate treatments. Manipulation is a traditionally well-established technique but in recent years it seems that arthroscopic capsular release has gained popularity. Manipulation is a relative time efficient and technically low-demanding procedure in which the glenohumeral joint is forced into different directions under general anaesthesia to release the capsular contracture, thereby increasing the range of motion of the joint. In arthroscopic capsular release the glenohumeral capsule can be released in a more controlled manner under direct vision. There are no prospective comparative trials available to display superiority of one procedure over the other. In addition, the optimal timing of both these interventions still has to be determined. An overview of the literature concerning this topic and a description of both procedures with its own advantages and disadvantages is provided.

Abstract
Arthroscopic labral repair is a widely performed and safe technique for anterior or posterior shoulder instability; however, complications have been reported in the literature. Postoperative injection of local anesthetic via an intra-articular pain pump should be avoided to prevent chondrolysis of the glenohumeral joint. Postoperative stiffness of the shoulder can be treated with physiotherapy, and a surgical treatment is indicated in shoulders that failed a conservative treatment. Although nerve injury is relatively rare, the axillary nerve should be given careful attention. Recurrent shoulder instability is the most common complication after labral repair, but most reported rates of recurrent instability after arthroscopic Bankart repair are less than 10 %. Augmentations, such as rotator interval closure and Hill-Sachs remplissage, have a potential to reduce the rate of recurrence. A better understanding of these possible complications, including their pathology and treatment, is essential for optimization of outcomes after arthroscopic labral repair.

Abstract
Shoulder arthroscopic procedures have become common in today's orthopedic practice. The safety of shoulder arthroscopy though well established, is not without complications both minor and significant. The true incidence of complications is difficult to identify in the current literature. However, as with all procedures, complications associated with shoulder arthroscopy do occur. General complications (ie, infection), those specific to shoulder arthroscopy (ie, positioning) and those associated with specific procedures (ie, failure) all have been recognized. The purpose of this article is to review the current literature regarding complications in shoulder arthroscopy, provide insight into the risk factors and types of complications and to provide guidelines on the prevention and management of complications if and when they occur.

Abstract
BACKGROUND It is currently unclear as to whether there is a difference in the clinical effectiveness of an arthroscopic capsular release compared to a manipulation under anaesthesia (MUA) in patients with recalcitrant idiopathic adhesive capsulitis. METHODS A systematic review was performed using computerized keyword searches of MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews. Two reviewers independently performed searches and article reduction. Studies that reported outcomes data following either a manipulation under regional or general anaesthesia or an arthroscopic capsular release in patients with idiopathic adhesive capsulitis were included. Data on clinical measures of shoulder range of motion and subjective outcome measures were extracted and summarized. RESULTS Twenty-two studies (21 studies provided level IV evidence) including 989 patients were included resulting in a comparison of 9 MUA and 17 capsular release groups. Patients were 60% female with a median age of 52 years old (range, 24-91 years). Median duration of symptoms and follow-up were 9 months (range, 3-50) and 35 months (range, 3-189), respectively. There were minimal differences in the median changes in abduction, flexion, and external rotation range of motion (ROM), and final Constant score between the MUA and capsular release groups. CONCLUSION The quality of evidence available is low and the data available demonstrate little benefit for a capsular release instead of, or in addition to, an MUA. A high quality study is required to definitively evaluate the relative benefits of these procedures.

[PMID: 23809447 DOI: 10.1016/j.arthro.2013.04.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2011] [Revised: 04/12/2013] [Accepted: 04/12/2013] [Indexed: 02/02/2023]
Abstract
PURPOSE The objective of this 2-part study is to report on the etiology, clinical findings, and predictors of disease progression (part I) and the results of treatment (part II) in a group of patients with glenohumeral chondrolysis. METHODS Forty patients presented with glenohumeral chondrolysis after treatment elsewhere. Twenty patients have been followed up since their initial presentation before arthroplasty (group 1), and 20 patients were referred either for management of complications arising after prosthetic arthroplasty or for evaluation only (group 2). RESULTS Thirty-seven patients received an intra-articular pain pump (IAPP) delivering bupivacaine, and 3 patients had prominent suture anchors or tacks. Symptoms related to chondrolysis developed in patients at a mean of 9.8 months (range, 1 to 34 months) after the index procedure. Radiographs showed joint space obliteration in 30 of 40 patients at most recent follow-up or before arthroplasty. Of the patients receiving an IAPP delivering bupivacaine, the majority received 0.5% with epinephrine. Higher bupivacaine dose (P < .05) and female gender (P < .05) were associated with a longer interval to onset of symptoms. In addition, a shorter interval to onset of symptoms predicted the need for subsequent surgery (P < .05) and a shorter interval to second-look arthroscopy (P < .001). CONCLUSIONS Post-arthroscopic glenohumeral chondrolysis is a devastating and rapidly evolving condition that most often strikes young patients. The use of IAPPs delivering local anesthetics should be abandoned because nearly all cases of glenohumeral chondrolysis in this series were associated with their use. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
PURPOSE The purpose of this study was to determine operating parameters for joint fluid lavage using radiofrequency (RF) in maintaining intra-articular temperatures ≤50°C in the hip joint and to then quantify the influence of flow rate on maintaining safe intra-articular temperatures. METHODS Fiberoptic intra-articular thermometers at radial distance intervals of 1, 2, 5, and 10 mm, spanning cross-sectional areas of 3.14, 12.56, 78.5, and 314.1 mm(2), respectively, from the RF probe were used in 3 human hip cadaveric specimens at room temperature, with 9 trials per variable, using a 3-portal technique with a capsule release. Using a new Dyonics RF System continuously at the superior capsulolabral junction for 90 seconds, continuous temperatures were recorded at 50 mm Hg inflow and variable outflow intervals: no flow and 5, 15, and 30 seconds. Lavages were 1 second in duration on suction. Statistical comparison was through multivariate regression analysis and a logistic model. RESULTS Temperatures reached ≥50°C at 5-mm radial distance from the probe in all but the 5-second pulse lavage group. Elevated temperatures were reached within 1 to 2 seconds locally (1- to 2-mm radial distance) and at a radial distance of 5 mm in the 15-, 30-, and 0-second lavage groups. Logistic regression revealed a reduction in the odds that temperatures ≥50°C will occur as flow frequency increases every 30 (odds ratio = 0.68, P = .086); 15 (odds ratio = -1.22, P = .0067); and 5 (odds ratio = -4.26, P < .0001) seconds. CONCLUSIONS Increasing-interval pulsed irrigation is effective in maintaining intra-articular temperature profiles below 50°C during use of continuous RF ablation. Five-second-interval pulsed lavage is the longest flow interval identified during which fluid 5 mm radially from the RF device never reached temperatures >50°C. CLINICAL RELEVANCE Clinical guidelines for using the RF ablation include: meticulous technique, intermittent use, good inflow and outflow, and pulsed lavage at frequent intervals.

Abstract
PURPOSE The primary objective of this study was to determine whether thermal stress potentiates the chondrotoxic effect of bupivacaine, resulting in decreased articular chondrocyte viability compared with exposure to bupivacaine alone. METHODS Bovine articular cartilage explants and cultured chondrocytes were treated with a range of thermal exposures (10 to 20 minutes at 37°C to 65°C) to create time/temperature viability curves and to determine threshold conditions for cell death. A second set of experiments was performed to determine whether subthreshold thermal stress potentiates bupivacaine toxicity. Explants were exposed to 37°C or 55°C for 10 or 20 minutes, and cultured chondrocytes were exposed to 37°C or 45°C for 10 or 20 minutes. Thirty minutes later, the explants and chondrocytes were treated with either 0.9% normal saline solution or 0.5% bupivacaine for 30 minutes. Chondrocyte viability was quantified 24 hours after treatment. RESULTS There was a temperature- and time-dependent decrease in chondrocyte viability above the thermo-toxicity threshold in both intact cartilage explants and cultured chondrocytes (55°C and 45°C, respectively; P < .05). Chondrocyte viability in cartilage explants was significantly lower after treatment with thermal stress for 10 or 20 minutes followed by bupivacaine for 30 minutes compared with treatment with bupivacaine at 37°C (bupivacaine and 55°C for 10 minutes, 0.09% ± 0%; bupivacaine and 55°C for 20 minutes, 0.08% ± 0%; bupivacaine and 37°C for 10 minutes, 37.4% ± 1.2% [P < .001]; and bupivacaine and 37°C for 20 minutes, 47.1% ± 0.8% [P < .001]). A similar trend was seen in cultured chondrocytes, although it was not statistically significant (P > .05). CONCLUSIONS Thermal stress potentiates the chondrotoxic effects of bupivacaine in intact cartilage, leading to decreased chondrocyte viability compared with exposure to bupivacaine alone. CLINICAL RELEVANCE Intra-articular injection of bupivacaine after arthroscopic procedures during which cartilage is exposed to elevated temperatures, such as with prolonged use of radiofrequency probes, may increase the risk of chondrocyte toxicity.

Abstract
BACKGROUND Postoperative chondrolysis in the knee joint caused by continuous intra-articular pain pumps infusing bupivacaine is a serious complication that severely affects function. We report the clinical course of a series of twenty-one patients who were referred to our clinic with this complication. METHODS A physical examination and a review of medical records were conducted. The condition of the articular cartilage was determined from operative notes, photographs, magnetic resonance images, and radiographs. Knee function was assessed with the Cincinnati Knee Rating System. RESULTS The study group included eighteen female and three male patients ranging in age from fourteen to forty-two years. The index procedures, all done elsewhere, included eighteen anterior cruciate ligament reconstructions, one meniscal repair, one arthroscopy, and one tibial tubercle osteotomy. An intra-articular high-flow-volume pump (200 to 270 mL) was used in ten patients, and a low-flow-volume pump (90 to 120 mL) was used in ten patients; the flow rate in the remaining patient was not documented. The devices used 0.5% bupivacaine in twenty knees and 0.25% in one knee, with 1:200,000 epinephrine added in eleven knees. Knee symptoms affecting daily activities occurred at a mean of 9 ± 7 months after the index procedure. Extensive chondrolysis with loss of articular cartilage of all three knee compartments occurred in six knees. In ten knees, two compartments were affected, and in five knees, one compartment was abnormal. All patients had marked limitations and pain with daily activities, and nineteen patients underwent forty-one subsequent surgical procedures. CONCLUSIONS Severe postoperative knee chondrolysis occurred after the use of a high or low-flow-volume pump infusing intra-articular bupivacaine, producing disabling knee symptoms. A variety of operative procedures failed to alleviate symptoms. Although this study does not define the incidence of knee chondrolysis after intra-articular bupivacaine pain-pump infusion, the severe complications reported here warrant its use to be contraindicated.

Abstract
Although the disease was first described in the hip, reports of chondrolysis in nearly all diarthrodial joints have since emerged with considerable variations in the literature.Despite speculation among clinicians and researchers about the implicit causal pathways and etiologic contributors associated with chondrolysis, definitive answers remain elusive.The term chondrolysis has been applied to varied levels of joint cartilage destruction from focal chondral defects to diffuse cartilage loss, revealing a lack of consistency in the application of diagnostic criteria to guide differential disease classification.Differentiating between the various potential etiologies associated with chondrolysis provides opportunities for the prevention of the disease.

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
Shoulder arthroscopy is generally a safe and effective method for treating a wide variety of shoulder pathology. Fortunately, complications following shoulder arthroscopy are rare, with reported rates between 4.6% and 10.6%.¹⁻⁷ These rates may be underestimated, as underreporting of complications and varying definitions of the term complication are likely. During shoulder arthroscopy, complications may occur at numerous points. The surgeon must be aware of potential problems and take necessary measures to prevent them. This article describes common complications after arthroscopic shoulder surgery. Although failure of treatment and postoperative stiffness are undesirable outcomes, they are not described.

Abstract
PURPOSE To report on our experience of patients who received infusion of bupivacaine with epinephrine after arthroscopic glenoid labral repair surgery and in whom glenohumeral joint chondrolysis subsequently developed, as well as to determine the incidence of such chondrolysis in our surgeons' patient populations. METHODS A retrospective chart review of 18 patients diagnosed with chondrolysis was carried out. All patients were from 2 experienced orthopaedic surgeons' practices. Details of their clinical course were obtained and summarized. These data were compared with all other arthroscopies completed by the 2 surgeons to determine the incidence of chondrolysis. RESULTS All 18 patients diagnosed with glenohumeral joint chondrolysis received postoperative infusion of bupivacaine with epinephrine through an intra-articular pain pump catheter (IAPPC). None of the patients received thermal energy as part of their procedure. None of the patients had evidence of glenohumeral joint infection, although an extensive workup was frequently undertaken. Clinically, patients presented with a stiff, painful shoulder. Examination showed decreased range of motion of the affected shoulder. Radiographs and magnetic resonance imaging showed joint space narrowing, as well as subchondral sclerosis and cyst formation. Of the 18 patients, 14 have since undergone repeat arthroscopic procedures, and 5 have received a humeral head-resurfacing operation. Within the same time period, there were 113 arthroscopies, with 45 pain pumps used. Chondrolysis developed in 16 of 32 patients with high-flow IAPPCs and 2 of 12 patients with low-flow IAPPCs (1 patient's IAPPC flow rate was not documented). CONCLUSIONS Although we cannot establish a causal link, the development of glenohumeral chondrolysis may be related to the intra-articular infusion of bupivacaine with epinephrine postoperatively. We thus caution against the use of IAPPCs. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
PURPOSE To determine the incidence of glenohumeral chondrolysis associated with the use of a continuous-infusion device in shoulder arthroscopy. METHODS A consecutive series of patients undergoing arthroscopic glenohumeral surgery with a postoperative continuous-infusion pump inserted into either the glenohumeral joint or subacromial space were evaluated for chondrolysis. Two pump types were used: group 1 received 100 mL of 0.5% bupivacaine without epinephrine infused at 2.08 mL/h, and group 2 received 270 mL of 0.5% bupivacaine without epinephrine infused at 4.16 mL/h. RESULTS We followed up 65 patients at a mean of 40 months. Of these, 29 had glenohumeral catheters (13 in group 1 and 16 in group 2) and 36 had subacromial catheters (19 in group 1 and 17 in group 2). The overall postoperative Constant, American Shoulder and Elbow Surgeons, Rowe, Single Assessment Numeric Evaluation, and Simple Shoulder Test scores were 84, 87, 77, 86, and 10, respectively, in those with glenohumeral catheters and 93, 94, 95, 89, and 11, respectively, in those with subacromial catheters. Three glenohumeral catheter patients were diagnosed with chondrolysis, all in group 2. CONCLUSIONS Chondrolysis developed in 3 of 16 patients (19%) with glenohumeral joint infusion of 0.5% bupivacaine without epinephrine at 4.16 mL/h for 65 hours. No patient using a 2.08-mL/h reservoir for 48 hours into the glenohumeral joint and no patient with a subacromial infusion device had chondrolysis. Clinical symptoms and radiographic evidence of chondrolysis developed before 12 months after surgery. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
PURPOSE This systematic review provides (1) a synthesis of existing clinical evidence that helps identify factors associated with the development of glenohumeral chondrolysis after arthroscopy (PAGCL), (2) a consolidated conceptualization of potential causal pathways that elucidate proposed mechanisms leading to PAGCL, and (3) a summary of implications for practice, policy, and future research. METHODS A computerized literature review using an iterative search process identified 245 publications in English between January 1960 and April 2009. After we applied inclusion and exclusion criteria, 35 articles were stratified into 4 categories of factors related to PAGCL: (1) patient factors, (2) surgical factors (preoperative and intraoperative), (3) postoperative factors, and (4) causal pathways. RESULTS The majority of studies (61%) focused on surgical factors correlated with PAGCL, and most were laboratory based (n = 21). Publications involving human subjects were descriptive case reports (n = 15), not epidemiologic studies. A total of 88 patients (91 shoulder surgeries) with PAGCL were identified in case reports. The majority of patients (55%) was male, and the mean age was 27.9 years (range, 13.1 to 64 years). Among patients, 68% (n = 53) had implants/anchors, 67% (n = 59) received local anesthetics through a pain pump, and 45% (n = 41) had surgeries involving radiofrequency devices. The causal pathways to PAGCL likely involve initiating and secondary cartilage injury due to mechanical, thermal, or chemical events. The result is a cascade of interactive cellular responses that may include inflammation and chondrocyte apoptosis causing disturbance of cellular metabolism with subsequent loss of the gliding surface, congruity, and synovial fluid, leading to increased friction and accelerated wear that ultimately yield PAGCL. CONCLUSIONS The literature is limited to correlates, rather than true risk factors, for PAGCL. Well-designed epidemiologic studies that examine various exposures in relation to health outcomes, while controlling for potential confounders, are needed to determine relative risks that allow causal inference, thereby facilitating sound practice and policy decision making.

Abstract
BACKGROUND Radiofrequency ablation devices are being used increasingly in arthroscopic surgery. However, there are concerns that excessive temperatures may damage the articular cartilage. The purpose of this study was to investigate the temperature profiles that occur within the glenohumeral space with the use of one commercially available radiofrequency ablation probe. METHODS Ten fresh-frozen human cadaver shoulder specimens were used. Intra-articular temperatures were measured at different time intervals over a two-minute period at a distance of 1, 3, 5, and 10 mm away from the probe. The radiofrequency probe was activated throughout the range of machine power settings, and irrigation fluid flow was varied (no flow, a flow at 60 mm Hg without suction, and a flow at 60 mm Hg with suction). RESULTS Temperatures deleterious to articular cartilage chondrocytes (i.e., those in excess of 50 degrees C) were seen with an increased duration of application, a decreased distance between the thermometer and the probe, and a decreased irrigation fluid flow rate. The highest recorded irrigation fluid temperature reached >80 degrees C after two minutes in a no-flow setting. The flow rate was found to be the most significant predictor of intra-articular temperature profiles. The various machine power settings had no apparent influence on temperature, meaning that higher probe settings are not necessarily associated with higher temperature profiles. CONCLUSIONS AND CLINICAL RELEVANCE These results demonstrate the importance of the management of the irrigation fluid flow rate across the joint during arthroscopic procedures that involve radiofrequency ablation. Even short intervals of limited flow could lead to supraphysiological temperature profiles and potentially to cartilage damage.

Abstract
BACKGROUND Chondrolysis has been reported as a sequela of arthroscopic shoulder surgery. Although the causes have yet to be fully elucidated, basic science and clinical evidence suggest a multifactorial origin. Surgical treatment in young patients with glenohumeral chondrolysis is particularly challenging, with little outcome data. HYPOTHESIS Glenohumeral chondrolysis has several causes and patterns of presentation. Biological resurfacing is a viable treatment option for symptomatic glenohumeral arthritis. Study Design Case series; Level of evidence, 4. METHODS Twenty patients (mean age, 19.7 years; range, 13.1-33.8) were referred for management of extensive glenohumeral arthritis after arthroscopy glenohumeral surgery (mean time postoperatively, 26 months; range, 3-73). Sixteen patients had an intra-articular pain pump placed for 2 to 3 days; 2 patients demonstrated prominent implants; and 2 had thermal treatment. Patients underwent revision surgery, including 7 biological resurfacings of the glenoid and humeral head, 4 biological resurfacings of the humeral head alone, and 7 other procedures. Eight patients having biological resurfacing were assessed just before the revision surgery, at a mean time of 3.1 years after revision (range, 1.9-6.5), with the American Shoulder and Elbow Surgeon scale and Simple Shoulder Test, Short Form 12 (physical and mental components), and visual analog scale score for pain. RESULTS Patient outcomes scores improved from 51 to 71 (American Shoulder and Elbow Surgeon scale, P < .01), 7 to 10 (Simple Shoulder Test, P < .02), and 5 to 3 (visual analog scale, P < .01). Preoperative range of motion demonstrated modest improvements from 119 degrees to 132 degrees of flexion, 42 degrees to 41 degrees of external rotation, and internal rotation from L2 to T12 level. Two patients required an additional surgery: 1 total shoulder arthroplasty and 1 capsular release with debridement. CONCLUSION Severe glenohumeral arthritis is a devastating postoperative complication of glenohumeral arthroscopy. Although not a universal finding, the use of glenohumeral pain pumps is a concern, as well as suboptimal anchor placement. Biological resurfacing permits modest functional improvement in a challenging shoulder condition.

METHODS Full-thickness bovine cartilage disks were isolated from the condylar surfaces of the radial-carpal joint by use of a 4-mm biopsy punch and were incubated in various concentrations of local anesthetics (e.g., bupivacaine) for varying amounts of time and stained for membrane integrity by use of ethidium bromide and SYTO 13 stain (Molecular Probes, Carlsbad, CA). Cell and nuclear morphology was assessed by transmission electron microscopy. RESULTS The addition of local anesthetics (i.e., 0.25% bupivacaine, 1% lidocaine, and 0.5% ropivacaine) to bovine articular cartilage disks had a negative effect on chondrocyte viability. Culturing bovine articular cartilage disks for increasing periods of time decreased chondrocyte viability for each of the local anesthetics, with significant negative correlations being shown between time of exposure to the drug and chondrocyte viability. These effects were also affected by the presence or absence of epinephrine in local anesthetic preparations. CONCLUSIONS Our results suggest that local anesthetics (i.e., bupivacaine, lidocaine, or ropivacaine) can have a detrimental effect on chondrocyte viability in bovine articular cartilage disks in a dose- and duration-dependent manner. CLINICAL RELEVANCE After arthroscopic surgery, it has been common practice to inject various local anesthetics into the joint for pain relief. Because adult chondrocytes have little or no capacity to regenerate, these results suggest that high-dose, long-term intra-articular administration of local anesthetics should be performed with caution.

Abstract
PURPOSE Our purpose was to evaluate the distance from the bony edge of the glenoid to the visible (or macroscopic) demarcation at the junction of the labrum and the articular cartilage. METHODS Ten fresh-frozen cadaveric upper extremity specimens were dissected. The shoulder was disarticulated and periarticular structures were removed, leaving the glenoid with the labrum attached. The macroscopic edge of the glenoid was then marked with a drill at the 3-, 4-, 5-, 6-, 7, 8-, and 9-o'clock positions, as defined by a clock face (right) and a reverse clock face (left). Soft tissue and cartilage were then removed, and the distance from the outer edge of the drill hole to the bony rim was measured. RESULTS The mean distance from the bony edge in hourly intervals starting at the 3-o'clock position anteriorly and extending to the 9-o'clock position posteriorly was 4.03 mm (range, 2.1 to 5.21 mm; SD, 0.96 mm), 4.2 mm (range, 2.1 to 5.31 mm; SD, 0.97 mm), 4.51 mm (range, 3.1 to 5.2 mm; SD, 0.91 mm), 5.14 mm (range, 3.1 to 7 mm; SD, 1.38 mm), 3.24 mm (range, 1.1 to 5.2 mm; SD, 1.4 mm), 3.78 mm (range, 1 to 6 mm; SD, 1.6 mm), and 4.28 mm (range, 2.1 to 7.3 mm; SD, 1.51 mm), respectively. A trend was noted for significant differences between locations, but this did not reach statistical significance (analysis of variance, P = .086). CONCLUSIONS The macroscopic edge of the labrum on the glenoid face does not correspond to the bony edge of the glenoid. The labrum overlaps onto the bony surface of the glenoid from a minimum of 1.6 mm to a maximum of 7.3 mm. CLINICAL RELEVANCE Our findings provide anatomic data that enhances the arthroscopist's ability to anatomically reconstruct the glenoid labrum.

Abstract
Shoulder arthroscopy has become a routine outpatient surgery. Pain control is a limiting factor for patient discharge after surgery, and several modalities are used to provide continued analgesia postoperatively. Regional anesthetic blocks and shoulder pain pumps are common methods to provide short-term pain control. Shoulder pain pumps can be used either in the subacromial space or within the glenohumeral joint. Several clinical studies suggested--which was confirmed by a bovine and rabbit cartilage study--that there is significant chondrotoxicity from bupivacaine, a local anesthetic commonly used in pain pumps. Postarthroscopic glenohumeral chondrolysis is a noninfectious entity associated with factors including use of radiofrequency thermal instruments and intra-articular pain pumps that administer bupivacaine, but there have been no cases reported with subacromial pain pump placement. Treatment options are difficult in a young patient with postarthroscopic glenohumeral chondrolysis, and understanding the literature with regard to risk factors is paramount to counseling patients and preventing this devastating complication.
