Tibial rotational osteotomy and distal tuberosity transfer for patella subluxation secondary to excessive external tibial torsion: surgical technique and clinical outcome.
Recurrent patella subluxation may be secondary to excessive external tibial torsion. The purpose of this study is to evaluate the clinical and radiographic outcome of patients undergoing tibial derotation osteotomy and tibial tuberosity transfer for recurrent patella subluxation in association with excessive external tibial torsion. ⋯ Case series, Level IV.

Isolated deviations in flexion and extension of the leg axis are rare. These deviations can be corrected if necessary by osteotomy and the range of motion (ROM) of the knee joint can be optimized. In addition to correction in the frontal plane, the tibial slope (i.e. inclination of the surface of the tibial joint) can also be influenced by osteotomy and therefore osteotomy can also be utilized to optimize the biomechanical stability of the knee joint. ⋯ Careful planning taking all three spatial planes and torsion into consideration is the foundation of a successful operation. A controlled surgical technique based on careful planning and some basic principles allows the alteration of the three dimensional alignment of the tibia.

Randomized Controlled TrialDoes a torsion adapter improve functional mobility, pain, and fatigue in patients with transtibial amputation?
Turning gait is an integral part of daily ambulation and likely poses a greater challenge for patients with transtibial amputation compared with walking a straight pathway. A torsion adapter is a prosthetic component that can increase transverse plane compliance of the prosthesis and decrease the torque applied to the residual limb, but whether this will improve patients' mobility, pain, and fatigue remains unknown. ⋯ For a moderately active group of amputees, the torsion adapter did not translate to substantial improvements in functional mobility and self-perceived pain and fatigue. The small increases in low- and medium-intensity activities with less pain interference when wearing a torsion adapter provides evidence to support prescribing this device for amputees with difficulty navigating the household and community environments.

Comparative StudyBilateral transfemoral/transtibial amputations due to battle injuries: a comparison of Vietnam veterans with Iraq and Afghanistan servicemembers.
Multiple limb loss from combat injuries has increased as a proportion of all combat-wounded amputees. Bilateral lower-extremity limb loss is the most common, with bilateral transfemoral amputations being the most common subgroup followed by bilateral amputations consisting of a single transfemoral amputation and a single transtibial amputation (TFTT). With improvements in rehabilitation and prostheses, we believe it is important to ascertain how TFTT amputees from the present conflicts compare to those from the Vietnam War. ⋯ Participants with TFTT limb loss from both conflicts reported similar scores for QoL and health status, although those from OIF/OEF reported better function and use of prosthetic devices. It is unclear whether the improved function is from age-related changes or improvements in rehabilitation and prosthetics. Some areas of future research might include longitudinal studies of those with limb loss and assessments of physical function of older individuals with limb loss as the demographics shift to where this group of individuals becomes more prominent.

Comparative StudyStability of two angular stable locking plates for open wedge high tibial osteotomy (HTO): TomoFix™ versus LOQTEQ® HTO plate.
The aim of this study was to test the mechanical stability of LOQTEQ® HTO plate in comparison to the TomoFix™ internal plate fixator. ⋯ The results of the present study showed that fatigue strength of the LOQTEQ® HTO plate was significantly higher in comparison to TomoFix™. These results justify the clinical use of the LOQTEQ® HTO plate.
