Background: Successful anterior cruciate ligament reconstruction requires secure healing between tendon and bone. Hypothesis: Bone morphogenetic protein-signaling plays an important role in tendon-to-bone healing. rhBMP-2, a powerful osteoinductive agent, can [...]

Background: Motion between a tendon graft and bone tunnel may impair graft incorporation and lead to tunnel widening. Hypothesis: Healing of a tendon graft in a bone tunnel is inhibited [...]

Background: Nonsteroidal anti-inflammatory drugs are commonly prescribed after rotator cuff repair. These agents can impair bone formation, but no studies have evaluated their impact on tendon-to-bone healing. Hypothesis: Traditional nonselective [...]

Background: Total Elbow Arthroplasty (TEA) for the rheumatoid arthritis (RA) has been popularized since 1980s. The outcomes of TEA using any type of implant design for RA has been satisfactory. On the other hand, many orthopedicians experience several postoperative complications. Among them, postoperative infection has still being the most troublesome and difficult to treat. This study is to clarify the causes of postoperative infection of TEA using Kudo's prosthesis for RA and discuss how to manage and prevent infection. Methods: 421 TEAs were performed for 405 cases with RA at the authors' institute during the period between 1982 and 2007. They were followed up for 1~25 years (Av. 12.3 years). The authors examined pain, the range of motion, roentgenograms and complications postoperatively. We were able to start treatment within 4 weeks after occurrence of infection. For surgical management of infected TEAs, debridement of the synovium and removal of the prosthesis with loosening were performed for all cases. In addition, all cases have been regularly and strictly followed-up with the elbow protector to prevent recurrence of infection since 2008. Results: There were 98 TEAs with the postoperative complications (23.3%). Eight out of 98 TEAs were infected (1.9%). Five of eight infected TEAs were primarily at the surgical scar site infection (SSSI) (60%), unknown causes in two, hematogenous course in 1. It's obvious that surgical scar site infection (SSSI) was the leading cause of postoperative infection in this study. Thus, the authors made the elbow proctor to avoid injuries of the skin around surgical scar site (SSS). Since 2008, all of the TEAs and revised TEAs have been applied with this protector. Conclusions: The authors reported 8 infected TEAs: 5 cases were revised, 2 with the brace, 1 had above the elbow amputated. The regular and meticulous follow up and application of the elbow protector were useful to prevent infection of post-TEAs using Kudo's prosthesis in RA. Since 2008, there have been no infection of post TEAs and revised TEAs. [ABSTRACT FROM AUTHOR]
