Is mid-sulcus line a predictive guide for tibial mechanical axis during total knee arthroplasty?

Background: Achieving appropriate alignment of components in total knee arthroplasty (TKA) is essential for optimal functional outcomes as well as implant longevity. Performing TKA in the absence of a computer-assisted navigation system (CANS) mandates the use of accurate anatomical landmarks for achieving appropriate alignment. In this study, we have evaluated the reliability of 'mid-sulcus line' as an anatomical landmark to guide tibial resection, with the intra-operative help of CANS.

Are soft tissue releases sufficient to correct moderate to severe flexion contractures during total knee replacement? Role of hamstring tenotomy and horizontal capsular release.

Background: Performing total knee arthroplasty (TKA) in arthritic knees with persistent flexion deformities is a challenging task because secondary tightening of surrounding soft tissues makes it difficult to achieve appropriate ligament balancing. In this study, we shared our algorithm for correction of flexion contractures of moderate to severe grade while performing TKA as well as their outcomes with 1 year of follow up.

Methods: Forty-three patients (61 knees) having knee arthritis with moderate to severe flexion contractures (Lombardi classification) were included in the study.

Minimally invasive plate osteosynthesis using a locking compression plate for distal femoral fractures.

Purpose: To evaluate treatment outcomes of minimally invasive plate osteosynthesis (MIPO) for distal femoral fractures in 31 patients.

Methods: 22 male and 9 female consecutive patients aged 21 to 65 (mean, 42) years underwent minimally invasive plate osteosynthesis using a locking compression plate (LCP) for distal femoral fractures. The causes of injury were vehicular accidents (n=24), falls (n=6), and assault (n=1).
