A biomechanical comparison of Achilles tendon suture repair techniques: Locking Block Modified Krackow, Kessler, and Percutaneous Achilles Repair System with the early rehabilitation program in vitro bovine model.
The Krackow technique has the advantage of high strength, though it is not minimally invasive. The "Locking Block Modified Krackow" (LBMK) peri-tendon fixation technique was designed for minimally invasive surgery. This study aimed to compare the biomechanics of LBMK with Kessler and Percutaneous Achilles Repair System (PARS) techniques using a simulated early rehabilitation program. ⋯ The biomechanical strength of the LBMK suture was significantly greater than Kessler and PARS. The reduced gap in the LBMK group suggests superior resistance to gap formation, which may occur during early postoperative rehabilitation.

The effect of coronal splits on the structural stability of bi-condylar tibial plateau fractures: a biomechanical investigation.
Surgical treatment of bi-condylar tibial plateau fractures is still challenging due to the complexity of the fracture and the difficult surgical approach. Coronal fracture lines are associated with a high risk of fixation failure. However, previous biomechanical studies and fracture classifications have disregarded coronal fracture lines. ⋯ Coronal articular fracture lines substantially affect the mechanical response of tibia implant structures specifically on the medial side. With this in mind, utilizing a clinically relevant fracture model for biomechanical evaluations regarding bi-condylar tibial plateau fractures is strongly recommended.

Preoperative psychological distress no reason to delay total knee arthroplasty: a register-based prospective cohort study of 458 patients.
Total knee arthroplasty (TKA) is effective in alleviating pain and improving function in patients with knee arthritis. Psychological factors are known to affect patient satisfaction after TKA. It is important to determine the effectiveness of TKA in patients with presurgical anxiety and/or depression to avoid excluding them from surgery. ⋯ II.

Outcome of proximal interphalangeal joint replacement with pyrocarbon implants: a long-term longitudinal follow-up study.
The aim of this study was to compare the short-, mid-, and long-term results of pyrocarbon PIPJ arthroplasty. ⋯ Pyrocarbon PIPJ arthroplasty has a risk of early complications necessitating revision surgeries. In spite of radiological implant migration, good pain relief, grip strength, and high quality-of-life ratings are stable for a long time.

The outcomes of mobile bearing unicompartmental knee arthroplasty and total knee arthroplasty on anteromedial osteoarthritis of the knee in the same patient.
Compared to total knee arthroplasty (TKA), mobile-bearing unicompartmental knee arthroplasty (UKA) is associated with better outcomes, such as an earlier recovery, less postoperative pain, lower morbidity and mortality, and a greater "feel" of a normal knee. However, no study has reported the clinical outcomes in patients with the same stage of osteoarthritis of the knee. The purpose of this study was to determine the clinical outcomes, including the Joint Forgotten Score (JFS), Oxford Knee Score (OKS), Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Kujala score after UKA on one knee and TKA on the opposite knee in the same patient. ⋯ UKA was associated with a better JFS and KOOS but was otherwise comparable to TKA and may be preferable.
