Randomized Controlled Trial Comparative StudyPost-operative blood loss in total knee arthroplasty: knee flexion versus pharmacological techniques.
To compare the blood loss and the blood transfusion between a control group and a group of patients following either a local administration of tranexamic acid or a mechanical post-operative knee flexion, a controlled randomized study was performed. ⋯ Prospective therapeutic study, Level I.

Combined trochleoplasty and MPFL reconstruction for treatment of chronic patellofemoral instability: a prospective minimum 2-year follow-up study.
Excessive trochlear dysplasia may be responsible for recurrent patellofemoral instability (PFI) due to a missing bony guidance for the patella in early flexion. Thus, an isolated medial patellofemoral ligament reconstruction (MPFLR) can be insufficient, since it mainly addresses instability close to extension and additionally can increase patellofemoral pressure leading to pain in flat or convex trochlear dysplasia. Therefore, in combination with a trochleoplasty, an anatomical trochlear groove is created, resulting in patellofemoral stability also in flexion, while patellofemoral pressure is normalized. In this prospective study, we evaluated the outcome of open trochleoplasty in combination with MPFLR with a minimum follow-up of 2 years for treatment of excessive PFI. ⋯ Prospective case series, Level IV.

Patellofemoral osteoarthritis after Insall's proximal realignment for recurrent patellar dislocation.
The aim of the present study was to retrospectively investigate the development of patellofemoral osteoarthritis after the historical Insall's proximal realignment for patellar stabilisation in patients with recurrent patellar dislocation. Furthermore, risk factors for recurrent patellar dislocation and for patellofemoral osteoarthritis development were evaluated. ⋯ IV.

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.

Increasing age and female gender are associated with early knee replacement following arthroscopy.
Early knee replacement following arthroscopy may be perceived as a failure of the original treatment and thus a poor use of resources. Factors that may be associated with increased risk of early replacement were explored in this study. ⋯ III.
