Review
Alloplastic total temporomandibular joint replacement (TMJR) is the treatment of choice for end-stage temporomandibular joint diseases. Extended TMJR (eTMJR) is a modification of the standard alloplastic fossa-condyle joint that includes components extending further to the skull base or the mandible. The aim of this study is to review the use of the eTMJR prosthesis for the treatment of large craniomaxillofacial defects. Data mining was performed according to the PRISMA statement using online search in databases such as PubMed (Medline), Google Scholar, Dimensions, Semantic Scholar and Web of Science. A total of 19 case reports, 08 case series and 03 retrospective studies were identified. A total of 49 patients were presented in the case reports and case series, who were implanted with 56 eTMJR prostheses (07 bilateral and 42 unilateral procedures). The mean age of the patients was 36.02±16.54 years, the male to female patient ratio was 1:1.72 and the mean follow-up time was 23.74 ± 19.83 months. The eTMJR prosthesis was most frequently used to treat ameloblastoma and hemifacial microsomia. Analysis of the retrospective studies was performed in three domains: the baseline characteristic of patients, treatment outcomes in terms of functional variables and complications after eTMJR prostheses implantation. This study concluded that the implantion of the eTMJR prosthesis was uncommon, that appropriate class of eTMJR prosthesis was not reported, and that the width of the mandibular component (like the length) of eTMJR prosthesis has substantial variations.

PURPOSE OF REVIEW
Joint replacement has revolutionized the treatment of end-stage arthritis. We highlight the key role of macrophages in the innate immune system in helping to ensure that the prosthesis-host interface remains biologically robust.
RECENT FINDINGS
Osteoimmunology is of great interest to researchers investigating the fundamental biological and material aspects of joint replacement. Constant communication between cells of the monocyte/macrophage/osteoclast lineage and the mesenchymal stem cell-osteoblast lineage determines whether a durable prosthesis-implant interface is obtained, or whether implant loosening occurs. Tissue and circulating monocytes/macrophages provide local surveillance of stimuli such as the presence of byproducts of wear and can quickly polarize to pro- and anti-inflammatory phenotypes to re-establish tissue homeostasis. When these mechanisms fail, periprosthetic osteolysis results in progressive bone loss and painful failure of mechanical fixation. Immune modulation of the periprosthetic microenvironment is a potential intervention to facilitate long-term durability of prosthetic interfaces.

Review
Total wrist arthroplasty are not used as widely as total knee and hip replacement. The functional hands are requiring surgeons to design a durable and functional satisfying prosthesis. This article will list the main reasons that cause the failure of the prosthesis. Some remarkable and representative prostheses are listed to show the devolvement of total wrist prosthesis and their individual special innovations to fix the problems. And the second part we will discuss the part that biomechanical elements act in the total wrist replacement (TWA). Summarize and find out what the real problem is and how we can find a way to fix it.

Review
Total joint arthroplasty of the hip and knee are successful orthopedic procedures that reduce pain and improve mobility in patients. As the implanted materials used in these procedures have improved, the lifetime of the implants has now reached more than 20 years. Younger patients are undergoing total joint arthroplasty at increasing rates, which has increased the need for improvements in materials for extended implant longevity. In this review, we aim to provide historical perspective on the evolution of ultra-high-molecular-weight polyethylene in total joint arthroplasty. We review this material with respect to its structure, mechanical properties, wear rates, sterilization effects, crosslinking, and other new polymer innovations. Ultra-high-molecular-weight polyethylene (UHMWPE) has been a cornerstone for total joint arthroplasty and with continued design improvements will continue to be vital to this successful orthopedic operation.

Review
Despite improved strategies to prevent prosthetic joint infection, as the total number of joint replacements increases, so does the absolute number of infections. Radiography serves as the first-line imaging modality for the assessment of a suspected prosthetic joint infection. Additionally, serial radiographs acquired after a surgery to eradicate a prosthetic joint infection are an important clinical tool. Prosthetic joint infections are often treated with a 2-stage replacement arthroplasty utilizing a prosthesis with antibiotic-loaded acrylic cement. While complications are uncommon with this procedure, imaging may demonstrate periprosthetic fractures, as well as spacer migration, joint dislocation, and spacer fracture. We describe the classification of prosthetic joint infections, the clinical and imaging diagnosis, and treatment strategies. Familiarity with the hardware utilized in the management of the prosthetic joint infection, and its potential complications is fundamental to accurate imaging interpretation.

Review
Periprosthetic joint infection (PJI) is one of the most catastrophic and difficult to manage complications following total hip and total knee arthroplasty. As the number of total joint arthroplasties continues to increase, the burden of PJI will continue to further strain resources. As such, orthopedic surgeons consider four principles crucial in appropriately managing difficult or complex cases of PJI: identification, debridement, antibiotics, and patience. Indications and techniques for nonoperative treatment, debridement with implant retention, and one- and two-stage exchange arthroplasty are reviewed. Despite optimal care, a subset of patients will experience failure and the role of resection, fusion, and amputation is discussed. Understanding appropriate patient selection, pathogens, and improved surgical techniques should form the basis of managing PJI.

Review
The management of irreparable rotator cuff tears associated with osteoarthritis of the glenohumeral joint has long been challenging. Reverse total shoulder arthroplasty (RSA) was designed to provide pain relief and improve shoulder function in patients with severe rotator cuff tear arthropathy. While this procedure has been known to reduce pain, improve strength and increase range of motion in shoulder elevation, scapular notching, rotation deficiency, early implant loosening and dislocation have attributed to complication rates as high as 62%. Patient selection, surgical approach and post-operative management are factors vital to successful outcome of RSA, with implant design and component positioning having a significant influence on the ability of the shoulder muscles to elevate, axially rotate and stabilise the humerus. Clinical and biomechanical studies have revealed that component design and placement affects the location of the joint centre of rotation and therefore the force-generating capacity of the muscles and overall joint mobility and stability. Furthermore, surgical technique has also been shown to have an important influence on clinical outcome of RSA, as it can affect intra-operative joint exposure as well as post-operative muscle function. This review discusses the behaviour of the shoulder after RSA and the influence of implant design, component positioning and surgical technique on post-operative joint function and clinical outcome.

Review
BACKGROUND
For the treatment of deformed finger middle joints that occur as a result of osteoarthritis or inflammatory and post-traumatic destruction, artificial joint replacement is an option to arthrodesis. Hereby mobility can be obtained, which is why this method generally has a higher acceptance.
DISCUSSION
What clinical and subjective results can be expected after artificial finger middle joint replacement and what is the expected complication rate for the different types of joints?
MATERIAL AND METHODS
We present our experiences with artificial joint replacement with various implants over the past decades as well as promising new developments of the last 10 years.
RESULTS
The silicone implant still remains the gold standard in joint replacement. For these implants, good long-term results and low revision rates have been documented. Due to the soft flexible material, however, lateral stability and preoperatively-existing axis deviations seem problematic. Initial studies with modular resurfacing implants appear promising and may eventually replace the silicone spacer over the long term. Consequently, long-term results of these modern implants are pending.
CONCLUSIONS
Painful osteoarthritis of the finger joint can be treated well with motion-preserving artificial joints. The complication rate appears to be decreasing. New generation modular surface prostheses seem to be relatively equal to the silicone spacer in terms of long-term outcomes.

Review
The results of wrist arthroplasty for severely destroyed and painful wrists are generally good in pain reduction, increased grip strength, and upper limb function. The wrist range of motion is usually preserved but not improved. Implant survival seems better than it was with earlier implant designs; however, there are problems of carpal component loosening. Patient selection plays an important role, requiring experience, careful patient information, and discussing the pros and cons of arthroplasty and partial or total wrist arthrodesis.
