An alloplastic total joint replacement (TJR) is an effective and reliable treatment option in non-salvageable end-stage temporomandibular joint (TMJ) disease. However, unilateral alloplastic TJR of the TMJ (TMJ TJR) could affect the other side natural joint because the physiologic action of both condyles is quite different during mandibular movement. In this study, we examined whether the unilaterally replaced alloplastic TMJ TJR affects the other side natural joint condition over long periods of time. Eight patients who received alloplastic TJR on one side were subjects in this study. All alloplastic TJR implants were stable in situ. The average maximum mouth opening was 37.5 mm (range 19–49 mm) pre-operatively and 44.1 mm (range 34–57 mm) post-operatively. This parameter gradually increased and reached the maximum at about twelve months after surgery. The post-operative change of pain level was significantly reduced from 3.5 to 0 on a pain scale of zero to ten. No significant complications in any joints were observed within the follow-up period. The shape of the natural joint sides showed slight changes but were functionally stable during the observation period. In this study, unilateral alloplastic TJR showed stable and reliable clinical results, either alloplastic TJR or healthy joint sides for quite long period of time.

Case Series Study

Background: Microfracture is the most common reparative surgery for osteochondral lesions of the talus (OLTs). While shown to be effective in short- to midterm outcomes, the fibrocartilage that microfracture produces is both biomechanically and biologically inferior to that of native hyaline cartilage and is susceptible to possible deterioration over time following repair. With orthobiologics being proposed to augment repair, there exists a clear gap in the study of long-term clinical outcomes of microfracture to determine if this added expense is necessary. Methods: A retrospective review of patients undergoing microfracture of an OLT with a single fellowship-trained orthopedic surgeon from 2007 to 2009 was performed. Patients meeting the inclusion criteria were contacted to complete the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscales and visual analog scale (VAS) for pain, as well as surveyed regarding their satisfaction with the outcome of the procedure and their likelihood to recommend the procedure to a friend with the same problem using 5-point Likert scales. Patient demographics were reviewed and included for statistical analysis. Results: Of 45 respondents, 3 patients required additional surgery on their ankle for the osteochondral defect, yielding a 10-year survival rate of 93.3%. Of surviving cases, 90.4% (38/42) reported being “extremely satisfied” or “satisfied” with the outcome of the procedure. The VAS score at follow-up averaged 14 out of 100 (range, 0-75), while the FAAM-ADL and FAAM-Sports scores averaged 90.29 out of 100 and 82 out of 100, respectively. Thirty-six patients (85.7%) stated that their ankle did not prevent them from participating in the sports of their choice. Conclusion: The current study represents a minimum 10-year follow-up of patients undergoing isolated arthroscopic microfracture for talar osteochondral defects, with a 93.3% survival rate and 85.7% return to sport. While biological adjuvants may play a role in improving the long-term outcomes of microfracture procedures, larger and longer-term follow-up studies are required for procedures using orthobiologics before their cost can be justified for routine use. Level of Evidence: Level IV, retrospective cohort case series study.

Prior to 1985, type 2 diabetes was a disease of adults. Simultaneously with the global epidemic of childhood obesity, type 2 diabetes has increased in children. Initially, the presentation of small case series of type 2 diabetes in children was met with skepticism. As the number and size of the case series grew and the first long-term outcomes of end-stage complications in young adults appeared in the literature, the international community took notice with guarded interest. Type 2 diabetes disproportionately affects the children of specific ethnic groups and from disadvantaged socioeconomic environments, especially Indigenous populations. The past decade has seen unprecedented intense global interest in the etiology, treatment, and prevention of type 2 diabetes in children.

PurposeTo report the long-term outcomes of Boston keratoprosthesis type I (B-KPro type I) implantation in the management of severe ocular surface disorders.MethodsRetrospective case series. Patients who underwent B-KPro type I implantation at the People’s Liberation Army General Hospital were enrolled between March 2011 and September 2019. Data regarding visual acuity (VA), B-KPro type I retention and postoperative complications were recorded and analysed.ResultsA total of 103 eyes of 100 patients who underwent B-KPro type I implantation were included. The main indications were chemical burn (59.2%), ocular trauma (25.2%), herpetic keratitis (11.7%) and autoimmune diseases (3.9%). The percentage of eyes with postoperative VA of 10/200 or better was 82.7% at 6 months, 82.8% at 12 months, 77.9% at 2 years, 72.4% at 3 years, 71.1% at 4 years, 69.4% at 5 years, 58.9% at 6 years, 56.8% at 7 years and 42.9% at 8 years. Preoperatively, 8.7% eyes were diagnosed with new-onset glaucoma. Retroprosthetic membrane formation occurred in 19.4% eye. Corneal melting occurred in 18.4% eyes. Sterile vitritis was diagnosed in 4.9% eyes and infectious endophthalmitis in 2.9% eyes. Retinal detachment occurred in 0.9% eyes.ConclusionsIn a Chinese patient group, B-KPro type I is a viable option for treating severe ocular surface disorders in eyes where conventional keratoplasty would have a poor prognosis, especially in patients with chemical and thermal burns. Improved visual outcomes and high retention rate can be achieved and maintained in most cases.
