Functional Outcome Based on Mechanical Axis Alignment Following Total Knee Arthroplasty.

Background Total knee arthroplasty (TKA) is the most commonly performed and highly successful surgical intervention for end-stage osteoarthritis of the knee, and it offers patients pain relief, functional recovery, and improved quality of life. The success of knee arthroplasty depends on various factors such as precise surgical technique, alignment of the limb and components, patient selection, and compliance with rehabilitation. Mechanical alignment of the lower limb has been considered an important factor in planning and assessing the success of TKA.

Fracture of the posterior process of talus.

Fracture of posterior process of talus is quite rare, but is associated with significant morbidity as it involves two articular surfaces. We report two such cases in which open reduction and internal fixation were done with good functional results. One of the cases had a concomitant medial malleolus fracture which to the best of our knowledge has not been reported so far.
