Introduction. Non-union is agonising for patients, complex for surgeons and a costly burden to our healthcare service; as such, its management must be well defined. There is debate as to the requirements for the successful treatment of such patients, in particular, the need for additional biological therapies to ensure union. This study's primary aim was to determine if operative treatment alone was an effective treatment for the non-union of long bones in the upper and lower limbs compared to the pre-existing literature using biological therapies. Materials and Methods. A single-centre retrospective cohort study using prospectively collected data was performed. Inclusion was defined as patients 16 years or older with a radiologically confirmed non-union of the upper or lower limb long bones managed with surgical treatment alone between 2014–2019, with at least a 12 month follow up. Patients with bone defects or whose non-unions were treated with biological therapies were excluded from this study. The primary aim was assessed via the outcomes of union, time to union and RUST score. Results. 82 patients were included, 43 receiving percutaneous interventions and 39 receiving open interventions. Overall, a union rate of 97.56% was achieved with a mean time to union of 6.43 months. The mean RUST score increased from 6.09 at diagnosis to a final RUST score of 11.36 (p < 0.0001). Surgical factors showed that percutaneous interventions were most successful with a union rate of 100.00% with a mean time to union of 6.29 months. Augmentation surgery was associated with the shortest time to union of 4.47 months. Binary regression showed no statistically significant influence of patient factors. In 16 patients, complications were observed, including limb length discrepancy, ongoing pain and subsequent ankle problems. Conclusions. These results show non-inferior outcomes using operative treatment alone in non-union management as compared to the pre-existing literature on using biological therapies. Percutaneous interventions showed the most successful results and patient factors seemed to have little influence on this method's success. The continued use of biological therapies as a first line treatment should be questioned

Objectives. Biologic agents (BIO) drastically changed the rheumatoid arthritis (RA) therapy from starting to use biologics at 2003 in Japan. The rate of orthopaedic surgery, especially total joint arthroplasty (TJA) may reflect trends in disease severity, management and health outcomes. Methods. We surveyed the number and rate of orthopaedic surgeries and TJA in RA treatment with BIO in the last decade, so called BIO-era. Results. We had 18,701 cases of orthopaedic surgeries, including 491 rheumatoid surgeries from 2004 to 2013. They contained 382 cases of total joint arthroplasties (78%), including 258 total knee arthroplasty (TKA), 80 total hip arthroplasty (THA), 18 total elbow arthroplasty (TEA), 14 total ankle arthroplasty (TAA), 4 swanson arthroplasty for fingers. The numbers of orthopaedic surgery increased year by year. The rate of rheumatoid surgeries not changed in the last decade (r=0.8, p<0.05, Fig. 1). The numbers of TSA and TEA in 2009–2013 increased twice compared to them in 2004–2008, but TKA and THA not changed. We had 241 RA patients treated by biologics agents from 2003, including 60 rheumatoid surgeries with the biologic therapy. Over half of rheumatoid surgeries were TJA (37 cases; 61%), including 26 cases for lower joint; 11 cases for upper joint. The rate of upper TJA more increased than that of lower joint in the RA patients with BIO in this decade. Conclusion. TJA for upper joint that improve the quality of life may increase in the RA patients with biologic therapy, because their disease activity and attitudes have changed year by year in this BIO-era

Juvenile idiopathic arthritis(JIA) is chronic inflammation commonly occurs in early childhood. Recently, biological therapies are used in JIA at the early stage as same as rheumatoid arthritis, due to retain joint cartilage. However, some of young patients have painful knee problems requiring knee replacement. We experienced 4 cases of JIA treated by knee arthroplasty. The average age at surgery was 33.5 years (range, 26–38 years) with a mean follow-up of 9.5 years (range, 5–18 years). We evaluated the knee range of motion and functional outcomes by the Knee Society Score (KSS), implant selection, postoperative complication, surgery of another joint. Mean range of motion improved from 76.3° (0°–120°) at pre-operation to 110.6° (80°–130°) at post-operation (P<0.05). Mean KSS increased from 47.3 ±20.1 preoperatively to 86.9 ±11.1 (P<0.01) at last follow-up and the mean KSS function from 27.5 ±25.9 to 62.5±20.2 at last follow-up (P<0.05). All of the TKAs were cemented, 5 were cruciate-retaining implant designs, whereas 2 TKAs had constrained posterior stabilized implant designs. Patellar resurfacing was undergone in all knees. Bone graft required in 1 knee within severe knee deformity. Complication were occurred in 5 knees. Medial instability in 2 knees. Skin necrosis, MCL avulsion, recurrence of the synovitis are one in each. All cases had polyarticular type. Previous THA had undergone in 5 hips, synovectomy in 3 knees, foot surgery in 2 feet. At latest follow-up, 1 of 8 TKAs (12.5%) had been revised, and had revision of its polyethylene exchange only. Patients with JIA often have valgus alignment with a flexion contracture and poor bone quality is also frequently compromised. Prescribed immunosuppressive medication or biological agents may cause to infection. In our series there were no infection, but some of these need much more soft tissue release because of severe deformity and flexion contracture. TKA survivorship for JIA is inferior to that typically seen in younger patients with osteoarthritis or rheumatoid arthritis. The knee of conservative therapy were often caused to severe functional limitations. Timimg of TKA may be indicated no matter how young the patient is. Extending timing of TKA may leads to worse outcome and postoperative function. But it may be caution that the surgical exposure can be difficult, because of stiffness, flexion contracture, bony deformity, osteopenia
