Treatment of Juvenile Idiopathic Arthritis

This review outlines the natural history, diagnosis, and management of juvenile idiopathic arthritis involving the hand and wrist. The discussion of management considers both nonoperative and surgical management to preserve functionality and mitigate long-term articular damage in children and adolescents. The review describes the current literature and identifies areas for further study.

Treatment of Early Undifferentiated Chronic Monoarthritis of the Wrist by Arthroscopic Wrist Synovectomy Combined with Partial Denervation

OBJECTIVE

Undifferentiated chronic monosecarthritis (UCMA) is a group of inflammatory joint diseases that has the potential to progress to other diseases and can seriously affect patients' quality of life. There is yet no unified consensus regarding treatment of UCMA. This study aimed to investigate the efficacy of arthroscopic synovectomy combined with partial wrist denervation in treating Larsen 1-3 UCMA.

METHODS

In this case series, we reviewed 14 patients with UCMA treated by arthroscopic synovectomy combined with partial denervation from February 2017 to June 2020. The mean duration of symptoms was 17.4 months (range, 4-60 months), and the mean follow-up was 13.3 months (range, 6-23 months). The anterior and posterior interosseous nerves were severed at the distal forearm, and the radiocarpal, midcarpal, and distal radial ulnar joint synovial membranes were arthroscopically resected at the wrist. The clinical evaluation indices included the visual analogue scale score (VAS) for pain, grip strength, range of (active) motion of the wrist, total active motion, and Mayo wrist score. Larsen's scoring method was used as the imaging evaluation index.

RESULTS

At the last follow-up, significant clinical improvements were observed in the visual analogue scale (VAS) score for pain (6.0 (5.0-6.3) vs 1.0 (1.0-2.3), P = 0.001) and Mayo wrist score (42.1 ± 9.7 vs 61.8 ± 12.3, P < 0.0001). No significant changes were found in grip strength (15.9 ± 4.5 vs 16.6 ± 4.7, P = 0.230) or the flexion-extension arc (58.9 ± 39.0 vs 64.3 ± 36.5, P = 0.317), although the mean and median did show positive changes. Among the three patients who showed progress in imaging, there was no significant difference in their pain and functional scores compared to those who did not progress. One patient underwent total wrist fusion 17 months after the operation.

CONCLUSION

Arthroscopic wrist synovectomy combined with partial wrist denervation can provide sustained pain relief and functional recovery for patients with Larsen 1-3 UCMA.

Arthroscopic Capsular Shrinkage Is Safe and Effective in the Treatment of Midcarpal Instability in a Pediatric Population: A Single-Center Experience of 51 Cases

Objective  Treatment of palmar midcarpal instability (PMCI) remains controversial and children can develop PMCI from asymptomatic hypermobility. Recently, case series have been published regarding the use of arthroscopic thermal shrinkage of the capsule in adults. Reports of the use of the technique in children and adolescents are rare, and there are no published case series. Methods  In a tertiary hand center for children's hand and wrist conditions, 51 patients were treated with arthroscopy for PMCI between 2014 and 2021. Eighteen out of 51 patients carried additional diagnosis of juvenile idiopathic arthritis (JIA) or a congenital arthritis. Data were collected including range of movement, visual analog scale (VAS) at rest and with load, and grip strength. Data were used to determine the safety and efficacy of this treatment in pediatric and adolescent patients. Results  Mean follow-up was 11.9 months. The procedure was well tolerated and no complications were recorded. Range of movement was preserved postoperatively. In all groups VAS scores at rest and with load improved. Those who underwent arthroscopic capsular shrinkage (ACS) had significantly greater improvement in VAS with load, compared with those who underwent arthroscopic synovectomy alone ( p  = 0.04). Comparing those treated with underlying JIA versus those without, there was no difference in postoperative range of movement, but there was significantly greater improvement for the non-JIA group in terms of both VAS at rest ( p  = 0.02) and VAS with load ( p  = 0.02). Those with JIA and hypermobility stabilized postoperatively, and those with JIA with signs of early carpal collapse and no hypermobility achieved improved range of movement, in terms of flexion ( p  = 0.02), extension ( p  = 0.03), and radial deviation ( p  = 0.01). Conclusion  ACS is a well-tolerated, safe, and effective procedure for PMCI in children and adolescents. It improves pain and instability at rest and with load, and offers benefit over open synovectomy alone. This is the first case series describing the usefulness of the procedure in children and adolescents, and demonstrates effective use of the technique in experienced hands in a specialist center. Level of Evidence  This is a Level IV study.

Arthroscopic synovectomy versus intra-articular injection of corticosteroids for the management of refractory psoriatic or rheumatoid arthritis of the wrist: study protocol for a randomized controlled trial (ARCTIC trial)

BACKGROUND

Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are inflammatory diseases that often affect the wrist and, when affected, can lead to impaired wrist function and progressive joint destruction if inadequately treated. Standard care consists primarily of disease-modifying anti-rheumatic drugs (DMARDs), often supported by systemic corticosteroids or intra-articular corticosteroid injections (IACSI). IACSI, despite their use worldwide, show poor response in a substantial group of patients. Arthroscopic synovectomy of the wrist is the surgical removal of synovitis with the goal to relieve pain and improve wrist function. The primary objective of this study is to evaluate wrist function following arthroscopic synovectomy compared to IACSI in therapy-resistant patients with rheumatoid or psoriatic arthritis. Secondary objectives include radiologic progress, disease activity, health-related quality of life, work participation and cost-effectiveness during a 1-year follow-up.

METHODS

This protocol describes a prospective, randomized controlled trial. RA and PsA patients are eligible with prominent wrist synovitis objectified by a rheumatologist, not responding to at least 3 months of conventional DMARDs and naïve to biological DMARDs. For 90% power, an expected loss to follow-up of 5%, an expected difference in mean Patient-Rated Wrist Evaluation score (PRWE, range 0-100) of 11 and α = 0.05, a total sample size of 80 patients will be sufficient to detect an effect size. Patients are randomized in a 1:1 ratio for arthroscopic synovectomy with deposition of corticosteroids or for IACSI. Removed synovial tissue will be stored for an ancillary study on disease profiling. The primary outcome is wrist function, measured with the PRWE score after 3 months. Secondary outcomes include wrist mobility and grip strength, pain scores, DAS28, EQ-5D-5L, disease progression on ultrasound and radiographs, complications and secondary treatment. Additionally, a cost-effectiveness analysis will be performed, based on healthcare costs (iMCQ questionnaire) and productivity loss (iPCQ questionnaire). Follow-up will be scheduled at 3, 6 and 12 months. Patient burden is minimized by combining study visits with regular follow-ups.

DISCUSSION

Persistent wrist arthritis continues to be a problem for patients with rheumatic joint disease leading to disability. This is the first randomized controlled trial to evaluate the effect, safety and feasibility of arthroscopic synovectomy of the wrist in these patients compared to IACSI.

Advances in wrist arthroscopic surgery in Indonesia

Since the 1990s, new insights in wrist arthroscopy have led to the introduction of numerous treatment methods. Consequently, therapeutic procedures are no longer limited to resection as more specialized repair and functional reconstruction methods, involving tissue replacement and essential structural augmentation, have been shown to be beneficial. This article discusses the most prevalent reasons and uses for wrist arthroscopy, with an emphasis on Indonesia’s most recent and major advances in reconstructive arthroscopic surgery. Joint debridement, synovectomy, ganglionectomy, capsular release, and osteotomies are frequent resection operations. Ligament repair and arthroscopy-aided reduction and fixation for fractures and nonunion are all examples of reconstructive surgery.

Role of Wrist Arthroscopy in Juvenile Inflammatory Arthritis

Background and Purposes  The wrist is the fourth most common joint to be involved in juvenile inflammatory arthritis (JIA), which is a common rheumatological condition affecting children. Wrist arthroscopy is well established in rheumatoid arthritis, but remains unexplored in JIA. The aim of this study is to investigate the role of wrist arthroscopy in JIA, with focus on those who are refractory to medical management. Methods  This is a prospective observational study, including consecutive patients with JIA undergoing arthroscopy between January 2016 and December 2020. Those over the age of 18 years and those with other rheumatological diagnoses were excluded. Data including pre-, intra-, and postoperative variables, demographics, and patient-reported outcomes were collated and are reported using standard measures. Results  A total of 15 patients underwent arthroscopy ( n  = 20 wrists). Synovitis was noted in all wrists on arthroscopy and synovectomy was performed in all cases. Other procedures were performed as indicated during the procedure. The median follow-up duration was 11.3 (interquartile range [IQR] 8.1-24.2) months. Median reduction of 4 (IQR 2.25-6) points on the Visual Analogue Score for pain on loading was noted postoperatively. Grip strength was improved in n  = 11/20 wrists and functional improvement was noted in n  = 18/20 wrists. Restriction of range of motion was achieved with a shrinkage procedure in patients with hypermobile joints. There were no postoperative complications, and no patients were lost to follow-up. Conclusion  In experienced hands, wrist arthroscopy is feasible, safe, and efficacious in the management of JIA, among patients who are refractory to medical management. Level of Evidence  This is a Level II study.

History of Wrist Arthroscopy

Wrist arthroscopy has a rich history, drawing on contributions from around the world. Its foundation was laid in Japan with Kenji Takagi and Masaki Watanabe, who developed the arthroscope and the techniques for arthroscopy. Across several decades they advanced the optic and lighting technology, allowing the miniaturization which made wrist arthroscopy technologically feasible. A safe and standardized technique for wrist arthroscopy was evolved by Terry Whipple, Gary Poehling, and James Roth in the 1980s, and they shared this with their fellow surgeons through courses and publications. The techniques then spread across the world, leading to widespread uptake and exploration of new therapeutic possibilities. The worldwide spread of wrist arthroscopy was accelerated by the European Wrist Arthroscopy Society (EWAS), founded in 2005 by Christophe Mathoulin. The Asia Pacific Wrist Association (APWA), founded by PC Ho in 2015, also extended the progression of wrist arthroscopy. This article brings together this history and tells the global story of its development through the recollections of those involved. The manuscript includes some amazing videos of the early historical arthroscopy. There are also videos of Gary and Terry describing some of their special memories of the early politics, developments, and evolution of wrist arthroscopy.

Arthroscopic Synovectomy of the Wrist in Patients With Rheumatoid Arthritis: A Systematic Review of the Current Literature

BACKGROUND

Rheumatoid arthritis (RA) of the wrist can lead to loss of wrist function and progressive joint destruction if inadequately treated. Arthroscopic synovectomy of the wrist may prove a valuable treatment for local inflammation.

OBJECTIVE

The aim of this study was to perform a systematic review evaluating functional outcomes and pain following arthroscopic synovectomy of the wrist in RA patients.

METHODS

A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) guidelines. MEDLINE, EMBASE, The Cochrane Library, Web of Science, and Google Scholar were searched for studies describing pain or functional outcomes following arthroscopic synovectomy of the wrist in RA patients (CRD42021270846). Risk of bias was assessed using the Methodological Index for Non-Randomized Studies. Data collection included patient characteristics, pain scores, wrist function questionnaires, secondary surgery, and complications.

RESULTS

Six noncomparative cohort studies were included, with a total of 153 arthroscopic synovectomies. Disease duration of RA ranged from 32 to 89 months, and radiographic progression was mild to moderate. The Methodological Index for Non-Randomized Studies scores ranged from 8 to 10 out of 16. Mean follow-up ranged from 21 to 95 months. Improvements were seen in pooled mean visual analog scale pain score (from 7.7 to 2.2, p < 0.05), pooled mean Modified Mayo Wrist Score (from 43.3 to 70.4, p < 0.05), and the Disability of the Arm, Shoulder, and Hand (from 67.5 to 36.5, p < 0.05). Two complications occurred, and 5 patients required secondary surgery.

CONCLUSIONS

There is limited evidence suggesting that arthroscopic synovectomy of the wrist improves wrist function and pain in patients with RA, with few complications. In centers with arthroscopic expertise, it can be considered as a treatment option.

Pulsed Electromagnetic Field Inhibits Synovitis via Enhancing the Efferocytosis of Macrophages

Synovitis plays an important role in the pathogenesis of arthritis, which is closely related to the joint swell and pain of patients. The purpose of this study was to investigate the anti-inflammatory effects of pulsed electromagnetic fields (PEMF) on synovitis and its underlying mechanisms. Destabilization of the medial meniscus (DMM) model and air pouch inflammation model were established to induce synovitis in C57BL/6 mice. The mice were then treated by PEMF (pulse waveform, 1.5 mT, 75 Hz, 10% duty cycle). The synovitis scores as well as the levels of IL-1β and TNF-α suggested that PEMF reduced the severity of synovitis in vivo. Moreover, the proportion of neutrophils in the synovial-like layer was decreased, while the proportion of macrophages increased after PEMF treatment. In addition, the phagocytosis of apoptotic neutrophils by macrophages (efferocytosis) was enhanced by PEMF. Furthermore, the data from western blot assay showed that the phosphorylation of P38 was inhibited by PEMF. In conclusion, our current data show that PEMF noninvasively exhibits the anti-inflammatory effect on synovitis via upregulation of the efferocytosis in macrophages, which may be involved in the phosphorylation of P38.

Clinical Outcomes of Hip Arthroscopy in Patients With Systemic Inflammatory Diseases Compared With Matched Controls at a Minimum of 2-Year Follow-Up

PURPOSE

To evaluate postoperative outcomes and preoperative risk factors for patients with underlying systemic inflammatory disorders after hip arthroscopy.

METHODS

A retrospective analysis of patients who had undergone hip arthroscopy, with a history of systemic inflammatory disease, was performed. This included patients with a diagnosis of lupus, a positive antinuclear antibody test, rheumatoid arthritis, psoriatic arthritis, sarcoidosis, inflammatory bowel disease, Reiter syndrome, and mixed connective tissue disease. These cases were 1:2 matched to a control group of patients with no history of systemic inflammatory disease based on age and sex. An a priori power analysis was conducted and A 1:2 case-control ratio was selected to increase study power. Inclusion criteria included all skeletally mature patients with hip pain refractory to nonoperative management who underwent hip arthroscopy for labral tears and femoroacetabular impingement. Skeletally immature patients, those with Tönnis grades of 2 or more (less than 2 mm of joint space), hip dysplasia, patients undergoing revision hip arthroscopy, and patients whose pain failed to improve after intra-articular injection were excluded. The primary outcome was rate of revision hip arthroscopy or total hip arthroplasty 24 months after surgery. Secondary outcomes included 2 patient-reported outcome scores, the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS).

RESULTS

Twenty patients (21 hip arthroscopy procedures) and 42 controls were included. There was no significant difference in proportion of patients who met failure criteria (28.6% vs 16.7%, P = .271) or 2-year survivorship (76.2% vs 83.3%, P = .496) between the systemic inflammatory disorder and control groups, respectively. Both groups had a significant improvement in mHHS and NAHS at 24 months compared with baseline; however, there was no significant difference in mHHS (P = .28) or NAHS (P = .22) at 24 months between the 2 groups.

CONCLUSIONS

Patients with underlying inflammatory conditions have similar 2-year outcomes after hip arthroscopy for intra-articular pathology compared with patients with no history of inflammatory disease.

LEVEL OF EVIDENCE

III, retrospective comparative study.

All-Trans Retinoic Acid Inhibits Migration and Invasiveness of Rheumatoid Fibroblast-Like Synoviocytes

Fibroblast-like synoviocytes (FLSs) are pivotal in inflammation and joint damage of rheumatoid arthritis (RA). They acquire an active and aggressive phenotype, displaying increased migration and invasiveness and contributing to perpetuate synovial inflammation and destruction of cartilage and bone. The main current therapies of RA are focused against inflammatory factors and immune cells; however, a significant percentage of patients do not successfully respond. Combined treatments with drugs that control inflammation and that reverse the pathogenic phenotype of FLS could improve the prognosis of these patients. An unexplored area includes the retinoic acid, the main biologic retinoid, which is a candidate drug for many diseases but has reached clinical use only for a few. Here, we explored the effect of all-trans retinoic acid (ATRA) on the aggressive phenotype of FLS from patients with RA. RA FLSs were treated with ATRA, tumor necrosis factor (TNF), or TNF+ATRA, and cell migration and invasion were analyzed. In addition, a microarray analysis of expression, followed by gene-set analysis and quantitative polymerase chain reaction validation, was performed. We showed that ATRA induced a notable decrease in FLS migration and invasion that was accompanied by complex changes in gene expression. At supraphysiological doses, many of these effects were overridden or reverted by the concomitant presence of TNF. In conclusion, these results have demonstrated the therapeutic potential of retinoic acid on RA FLS provided TNF could be counterbalanced, either with high ATRA doses or with TNF inhibitors. SIGNIFICANCE STATEMENT: All-trans retinoic acid (ATRA) reduced the rheumatoid arthritis (RA) fibroblast-like synoviocyte migration and invasiveness and down-regulated gene expression of cell motility and migration genes. At supraphysiological doses, some of these effects were reverted by tumor necrosis factor. Therefore, ATRA could be an RA drug candidate that would require high doses or combined treatment with anti-inflammatory drugs.

Wrist Arthroscopy in Juvenile Idiopathic Arthritis: A Review of Current Literature and Future Implications

Introduction  Juvenile Idiopathic Arthritis (JIA) is the most common rheumatological condition in children and frequently affects the wrist. The roles for wrist arthroscopy and arthroscopic synovectomy (AS) in JIA are unclear. Our aim was to find the current evidence supporting its use. Methods  Systematic literature review of relevant publications from 1990 to present in the Cochrane Library, Clinical Knowledge Summaries, DynaMed, PEMSoft, NICE Guidance, MEDLINE, EMBASE, and PubMed. Results  We found no publications detailing the use of arthroscopy or AS specifically in patients with JIA involving the wrist. There is evidence that AS reduces pain, improves function, and induces remission in patients with rheumatoid arthritis resistant to medical management. Discussion and Conclusion  Although there is paucity in evidence for the use of AS in the wrists of patients with JIA, studies suggest it to be safe and effective, and could be applied to patients with refractive JIA. It is possible that early identification of patients suffering from JIA with extensive joint destruction and little symptoms could benefit from AS, delaying joint destruction and preserving function.

Optimizing Rheumatoid Arthritis Patients for Surgery

PURPOSE OF REVIEW

The purpose of this review is to guide providers on how best to optimize the health of patients with rheumatoid arthritis (RA) planning surgery, to reduce risk and complications and achieve the best outcomes.

RECENT FINDINGS

The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) have issued a recent guideline on perioperative management of antirheumatic medications in patients with RA. Patients with RA will continue to need surgery. Newer literature is helping to plan the perioperative period to help reduce complications and improve outcomes.

Improved quality of life and joint functions in patients with knee rheumatoid arthritis who underwent five portal arthroscopic synovectomy

Objectives

To evaluate the outcomes of patients with rheumatoid arthritis (RA) of the knee who underwent five portal arthroscopic synovectomy, with or without post-operative negative pressure drainage (NPD).

Material and Methods

A prospective clinical trial was performed. Patients with class I, II, and III RA of the knee were enrolled. They underwent five portal arthroscopic synovectomy. Post-operatively, they received either NPD (group A) or non-NPD (group B). Health assessment questionnaire (HAQ), disease activity score 28 (DAS 28), and Lysholm knee joint score were evaluated before the operations, and at six weeks, three months, and one year after the operations.

Results

A total of 36 patients were enrolled into the study, with 63.9% (23) female patients and mean age of 47.2 years old. All of the patients had clinical symptoms (joint swelling, pain, and dysfunction) for at least six months with poor responses to the traditional pharmaceutical therapy. There were 12, 16, and eight patients in class I, II, and III RA groups, respectively (six IA, six IB, eight IIA, eight IIB, four IIIA, and four IIIB). One year after the operation, patients had statistically significant improvements on HAQ, DAS 28, and Lysholm knee joint scores. More improvements were observed in patients with class I diseases. There were no statistically significant differences between group A and B.

Conclusion

Five portal arthroscopic synovectomy could increase the quality of life, decrease disease activities, and improve joint functions in patients with RA. More benefits were observed in patients with early disease developments. Patients in the NPD group did not show more improvements compared to the patients in the non-NPD group.

Arthroscopic Synovectomy of Wrist in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a systemic inflammatory disorder affecting multiple joints. Wrist involvement is common. Patients with persistent symptoms despite medical management are candidates for surgery. Synovectomy can provide pain relief and functional improvement for rheumatoid wrist. Arthroscopic synovectomy is a safe and reliable method, with minimal postoperative morbidity. This article reviews the role, technique, and results of arthroscopic synovectomy in the rheumatoid wrist.

Patient rated outcomes study into the surgical interventions available for the rheumatoid hand and wrist

INTRODUCTION

A multitude of surgical interventions are recognised for the treatment of the rheumatoid hand and wrist, however there seems to be a distinct lack of patient rated outcome measures (PROMs) studies reporting on the efficacy of these procedures. The aim of this study was to assess the PROMs related to hand and wrist surgery in patients with rheumatoid arthritis (RA).

MATERIALS AND METHODS

A single surgeon series identified 94 patients (133 hands) with RA who had undergone one of eight surgical procedures (Swanson's arthroplasty, finger joint or wrist arthrodesis, carpal tunnel decompression, posterior interosseous nerve denervation, RA nodule excision, synovectomy/tenosynovectomy and tendon repair/release) with a mean follow-up period of 3 years. The primary outcome measures were the same for all patients and comprised the validated modified score for the assessment and quantification of chronic rheumatoid affections of the hand (M-SACRAH) and a separate satisfaction questionnaire.

RESULTS

Highly significant improvements in both function and pain scores are reported across the cohort as a whole following hand surgery, with this pattern replicated within all of the operative subgroups. In keeping with these favourable results very high levels of overall satisfaction were reported with 93 % of patients reporting themselves to be very or fairly satisfied with their procedure.

CONCLUSIONS

Overall, patient reported outcomes in functional, stiffness and pain domains of the M-SACRAH questionnaire appear very favourable across the range of surgical procedures that can be performed in the rheumatoid hand. We believe this data supports the use of all the procedures explored, and will be helpful in patient guidance.

[Wrist arthroscopy : challenging procedure of modern hand surgery]

Arthroscopy of the wrist has developed in the shadow of arthroscopy of the large joints. Nowadays, wrist arthroscopy has a relevant importance in the diagnostics and therapy in hand surgery and is indispensable for serious surgery of the wrist. Special equipment and extensive knowledge of the surgeon are necessary for carrying out the procedure.
