Early improvement in physical activity and function after total hip arthroplasty: Predictors of outcomes.

Objectives: This study aims to assess early changes in physical activity and function after total hip arthroplasty (THA) using both subjective and objective methods, and to identify predictors of outcomes of THA.

Patients And Methods: Between October 2014 and October 2015, a total of 50 patients (14 males, 36 females; mean age 57.1±13.

Are metric parameters sufficient alone in evaluation of the patellar instability? New angular measuring parameters.

Purposes: When the evaluation of patellar instability is examined from the aspect of the conical-cylindrical anatomy of the tibia, metric measurement parameters such as the tuberositas tibia (TT)-trochlear groove (TG) and patellar tendon (PT) insertion-trochlear groove (TG) distances are not sufficient. We asked whether defined angular parameters reveal the rotational movement of the tuberositas tibia on the tibia shaft, additional to the metric parameters and there is a correlation between the metric and angular parameters.

Methods: 19 patients with patellar instability and 22 patients without patellar instability were evaluated.
