RESUMO
OBJECTIVE: Although the two-stage technique is a validated strategy in periprosthetic joint infections, there is a lack of data on the patients' clinical outcomes after the spacer placement. This study aims at evaluating the quality of life, joint function, and pain in patients over 70 years affected by periprosthetic joint infection treated with a two-stage exchange using metal on polyethylene spacers. PATIENTS AND METHODS: We conducted a follow-up study to evaluate the quality of life and functionality of consecutive patients over 70 years treated for PJI at our institution using a validated assessment set including the Western Ontario and Mac Master University (WOMAC) score, Knee Society Score (KSS), numerical rating scale (NRS). Knee Range of Movement (ROM) before and after the surgery was also analyzed. RESULTS: Forty-five patients with a mean age of 76 ± 5.3 years were included. Coagulase-negative staphylococci were the most isolated microorganisms. In the preoperative study group, the WOMAC score was 48.4 ± 18.9, and the KSS objective and functional scores were 37.6 ± 17.3 and 27.6 ± 22.3, respectively. NRS was 7.3 ± 1.8. After three months of follow-up, we found better results than preoperative clinical evaluation. We retrieved similar results comparing our post-operative PROMS (WOMAC and KSS scores) with published thresholds for treatment success two months after primary total knee arthroplasty. The infection eradication rate was 87%. CONCLUSIONS: The two-stage technique confirmed its efficacy in the treatment of PJI. Patients over 70 years who had undergone the first stage of the two-stage technique for PJI showed a good quality of life and knee function.

Over the last years, an increased number of studies have reported the use of cone beam weightbearing computed tomography (WBCT) in the assessment of foot and ankle pathology. This new technology has enabled to overcome the limits inherently related to two-dimensional radiographs (superimposition bias, operator-related bias, rotation bias) and to obtain images reproducing the bones and joints anatomy during physiological standing with a low radiation dose. We performed a review of the current literature to summarize the evidence about the use of 2D or 3D measurements on WBCT images in various foot and ankle conditions. Our aims were to describe measurements proposed so far and to report data on reliability and validity from primary authors.

Two-stage exchange in infected total knee arthroplasty is a reliable technique, but it has a high rate of blood loss. The study aims to compare the pre-operative and post-operative haemoglobin levels, the rate of transfusion, and the blood loss in two-stage exchange. From July 2018 to July 2019, eighteen patients underwent two-stage exchange of their infected total knee arthroplasty. Local and systemic tranexamic acid was administered in both surgical stages. Calculated blood loss was 2246 mL (range 1528 - 2850) in the first stage and 2388 mL (1873 - 2829) during reimplantation, respectively. The corresponding transfusion rate was 55 % and 67%, respectively. With the numbers available, these differences were not significant. In conclusion, this study shows that the blood loss and transfusion rate are similar during the two stages of exchange knee arthroplasty for infection.

Polyvinyl alcohol hydrogel implants (also known as Synthetic Cartilage Implant or Cartiva® have been described in the treatment of degeneration of the first and second metatarsophalangeal joint (MTPJ). We reviewed literature to report characteristics of devices on the market and investigate their efficacy and safety. Following the PRISMA checklist, the Medline and Scopus databases were searched, including studies reporting use of Cartiva® for treating joint degeneration of the first and second MPTJ. Studies were searched for surgical technique, postoperative protocol, clinical scores, complications and reoperations. We found that, although some studies suggest that the use of Synthetic Cartilage Implant (Cartiva® is effective in the treatment of hallux rigidus in providing symptoms relief without sacrifice of joint motion, the redundancy of cohorts reported in studies and the frequency of conflict of interest reported by authors weaken the strength of evidence available and warrant further studies. Regarding the treatment of the second MTPJ ailments, no recommendation can be formulated to date due to the lack of primary studies.

The pseudoarthrosis (PSA) of scaphoid leads to alteration in load transfer in the wrist joint. Its treatment aims to achieve consolidation to improve clinical complaints and prevent post-traumatic arthritis. The indication for using vascularized bone grafts is still controversial. This prospective comparative study aimed to compare consolidation rate and time to healing of scaphoid PSA treated by volar distal radius vascularized bone graft vs non-vascularized iliac bone graft. Nine patients underwent vascularized grafting of scaphoid PSA. These patients were compared to a control group consisting of twelve patients treated with iliac crest-free bone graft. PSA consolidation was obtained in 8 of 9 patients (88%) and 9 of 12 patients (75%) in the study and control group, respectively. The difference in consolidation rate was not significant. Two of three patients with AVN of the proximal pole in the study group (66%) went to consolidation. In the control group no patient with AVN obtained bone consolidation. This difference almost reached statistical significance (p = 0.083). The mean time to consolidation was 8.6 weeks (range 8-11) and 11.7 weeks (range 10-16), respectively, in the study and control group. This difference was significant (p < 0.05). In conclusion, the distal radius vascularized graft led to satisfactory consolidation rate of PSA in the current study, even in cases of AVN of the proximal pole. Moreover, the vascularized bone graft resulted in shorter healing time compared to the non-vascularized graft.

The aim of this systematic review was to understand which procedure-total or partial wrist denervation-provides better results in terms of pain relief and function. This review was registered on PROSPERO (CRD42018088856). We searched the Medline (PubMed), Web of Science and Scopus databases. Twenty-one studies were included in this review. We assessed the quality of the studies using the Coleman Methodological Score. Data on demographics, surgical indications, diagnostic methods, follow-up periods, type and rates of complications, survivorship of the procedure, return to work, and outcome measures were recorded. A total of 1065 patients were included in this review; the mean quality of the studies included was considered poor. The outcomes could not be analyzed because none of the studies had reliable outcome data reported, but both procedures were effective in terms of pain relief and range of motion. Partial wrist denervation has an average subsequent procedure rate of 19%. Total wrist denervation had an average subsequent procedure rate of 4.7%. No complications were reported in any patient who underwent partial wrist denervation versus 20 patients who underwent total wrist denervation. Both partial and total wrist denervation are safe and reliable procedures that can provide good pain relief and preserve wrist range of motion. Total wrist denervation offers better long-term outcomes in term of pain relief, with fewer subsequent procedures being needed compared to partial denervation, and with a low complication rate. LEVEL OF EVIDENCE: Level III, Systematic review, Therapeutic.

Over the past decade, the incidence of revision arthroplasty due to infection has increased substantially, often resulting in multiple surgical interventions with variable success rates and poor clinical outcome. Intraoperative wound irrigation has been proposed to reduce bacterial bioburden and contamination, but currently there is no widely accepted recommendation for the use of topical antiseptics, whether as separate molecules or as a mixed solution. We reviewed studies regarding the use of intraoperative topical antiseptics, their security profile and efficacy in preventing and treating infections of orthopedic implants and introduced a possible combination that may prove valuable in the future.

The aim of this systematic review was to analyze the failure rates among different trapeziometacarpal interposition implants used to treat thumb basal joint osteoarthritis. We searched Medline (PubMed), Web of Science and Scopus databases, to identify articles reporting on thumb interpositional arthroplasty, in English literature. We excluded studies with less than 35 cases and with a follow-up shorter than 24 months. Twenty-one studies were included. We assessed the quality of the studies using the Coleman Methodological Score. The mean quality of the studies was moderate. The total number of procedures included in this review was 1205. The failure rate for interposition implants was 11%. The main longterm complication was dislocation, which is also the major reason for revision.

Purpose Septic knee arthritis following arthroscopy is a rare but dreaded complication. Definition and management of knee deep infections are quite discussed in literature. In this review, literature regarding infections after knee arthroscopy is analyzed highlighting the incidence, causative bacteria, risk factors as well as clinical outcomes. Methods We performed a review of the literature matching the following key words: "septic arthritis" OR "infection" AND "arthroscopy" AND "knee." Knee arthroscopic procedures, such as debridement, meniscectomy, meniscus repair, synovectomy, microfracture, and lateral release, were considered. Complex procedures, such as ligament reconstruction, fractures, or complex cartilage repair techniques, were not included. Results Thirteen studies were included in this review. Incidence of infection ranged from 0.009 to 1.1% in patients undergoing simple arthroscopic procedures. Staphylococci are the most commonly isolated organisms from postarthroscopy infection. Use of intraoperative intra-articular steroids, smoking, obesity, male sex, diabetes, number of procedures performed during surgery, time of surgery, and tourniquet time of more than 60 minutes have been certified as risk factors for knee infection. Conclusion Postarthroscopy septic arthritis of the knee causes significant morbidity, usually requiring readmission to the hospital, at least one additional operation, and prolonged antibiotic therapy, both intravenous and oral. Prompt diagnosis and treatment are associated with a high success rate. Level of Evidence Level IV, systematic review of I-IV studies.
RESUMO
BACKGROUND: The purpose of this study was to determine the long-term clinical and radiographic outcome in a group of patients treated with resection of the proximal pole and tendon ball arthroplasty because of a scaphoid non-union. PATIENTS AND METHODS: 15 patients affected by scaphoid non-union and treated with resection arthroplasty were studied at a mean follow-up of 9.1 years. The assessment included a visual analogue scale (VAS) to evaluate pain, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and the measurement of grip and pinch strength. We also evaluated pre-operative and follow-up radiographs to determine the stage of SNAC wrist. RESULTS: We obtained a good subjective clinical result in 11 patients and a poor result in 4. Mean VAS and DASH score at follow-up was 1.2±1.2 and 12±12,1, respectively. Grip and key pinch strength in the surgically treated hand were 89% of the contralateral hand. There was significant increase in the SNAC stage at follow-up with respect to the preoperative evaluation in the operated wrist. CONCLUSION: Resection of the proximal pole and tendon ball arthroplasty provided long-term relief of pain and good functional results in most patients affected by scaphoid non-union. This technique did not affect the natural history of SNAC wrist with its clinical and functional consequences.

We present a retrospective study of 107 cases of thumb carpometacarpl joint arthrodesis. The aim of our study was to analyse our population and to compare the outcomes of patients who obtained bone union with the patients who did not. There were no statistical differences in most of the clinical outcomes (DASH score, visual analogue scale, Kapandji test, grip, and key pinch) between the two groups of patients; there were fewer cases of scaphotrapeziotrapezoid arthritis in the group that did not obtain bone union. We conclude that the bone union is not necessary for a good outcome. Level IV of evidence.

A prospective study was undertaken to assess the outcomes of a series of patients treated using pyrocarbon implant arthroplasty after partial trapeziectomy for trapeziometacarpal joint osteoarthritis. We analysed the results of this procedure in 27 trapeziometacarpal joints of 25 patients. The mean follow-up interval was 34 months (range 26-52). The study showed that pyrocarbon interpositional arthroplasty provided excellent pain relief and high patient satisfaction. Overall function, according to disabilities of the arm, shoulder and hand (DASH) score, improved from 48 points preoperatively to 14 points at the last follow-up assessment. Key pinch strength recorded in the operated hands was comparable with the results obtained in the contralateral hand and in healthy individuals from the same population. No further operations were performed in the study group. Partial trapeziectomy with pyrocarbon arthroplasty may prove to be a successful option for the treatment of trapeziometacarpal joint osteoarthritis. Further long-term comparative studies are warranted.

The purpose of this study was to assess the long-term clinical results and morphological changes after tendon ball arthroplasty for advanced Kienböck's disease. Twenty-six patients were reviewed, with a mean follow-up interval of 125 months (range 50-226). At follow-up, mean score on the Disabilities of the Arm, Shoulder, and Hand questionnaire was 7.7 and mean visual analogue scale score for pain was 1. Mean carpal height ratio was significantly reduced with respect to the pre-operative value. On magnetic resonance imaging scans, cartilage damage, synovitis, and erosive or oedematous changes in the bones were detected in most patients. Calcification in the defect filled by the tendon ball was seen in all patients. Narrowing of the radioscaphoid joint and the presence of intercarpal synovitis were negatively associated with clinical outcome. Tendon ball arthroplasty in advanced Kienböck's disease results in long-term satisfactory clinical outcomes, despite widespread changes in the bones and joints within the wrist.
