A new method of oblique tibial metaphyseal osteotomy that uses a single osteotomy cut has been used to allow correction of multiplanar rotational deformities in children. Graphs are used to predict the necessary angle of osteotomy. The osteotomy is performed through a 1-cm incision in the proximal tibial metaphysis, using multiple drill holes and an osteotome. Correction is maintained by casting with or without internal fixation. Fourteen such osteotomies have been followed an average of 27 months without major complications. This osteotomy allows maximal maintenance of length, stability, and metaphyseal contact through a small, cosmetically acceptable incision. Minimal soft-tissue dissection is necessary.

Stress radiography of medial knee instability provides a reliable correlation with the severity of injury and medial joint space opening-A robotic biomechanical cadaveric study.

Purpose: The medial collateral ligament (MCL), and posterior oblique ligament (POL) are the primary valgus stabilisers of the knee, and clinical examinations in grading valgus instability can be inherently subjective. Stress radiography of medial-sided knee injuries provides objective diagnosis and was analysed in this study. We hypothesised that (1) medial joint space opening would increase cutting the superficial MCL (sMCL), POL and anterior cruciate ligament (ACL); (2) isolated deep MCL (dMCL) injury would not increase medial joint space opening; (3) medial joint space opening would increase at higher flexion angles.

Background: A contemporary trend favours a restricted kinematic alignment (rKA) strategy, incorporating safe boundaries to restore a variable percentage of a patient's natural alignment.This study aims to compare preoperative and postoperative coronal plane knee alignment (CPAK) in patients undergoing bilateral TKA with SAIPH implants (MatOrtho, UK). The concept was to control the implant (same prosthesis both sides), patient (bilateral model) and assess what effect any surgical alteration in alignment had on patient's outcomes measured by patient-reported outcome measures (PROMS) and patient satisfaction.

The formation of a functional tibial stump after combat injuries with extensive tissue damage is sometimes difficult. We describe a case of reconstruction of the tibial stump after a mine-blast injury. In this case, the fibula was completely removed as a result of fracture, and the tibia was amputated at the border of the upper and middle thirds.

Indication for this hemi-wedge high tibial osteotomy is the combination of medial osteoarthritis or cartilage damage, varus deformity of >10°, and medial proximal tibial angle of <80°. The proximal lateral tibia is exposed via a skin incision of approximately 10 cm length between the tibial tuberosity and the head of the fibula. After detachment of the anterior tibial muscle, a first oblique guidewire marks the main osteotomy plane and a second guidewire marks the hemi-wedge.
