Effects of the Use of Tourniquet in Total Knee Arthroplasty on the Clinical and Functional Outcomes with 5 Years of Follow-up: A Randomized Controlled Trial.

The use of tourniquet in total knee arthroplasty (TKA) had a lot of controversies with no clear agreement about the advantages and disadvantages of tourniquet. This study aims to show the effects of tourniquet use in TKA on the functional and clinical outcomes with follow-up of 5 years. This is a randomized, double-blind, and single-center study of 101 patients who were treated by TKA and divided randomly into two groups.

Open versus arthroscopic release for lateral patellar compression syndrome: a randomized-controlled trial.

Introduction: Lateral patellar compression syndrome is one of the causes of anterior knee pain in young adults and resulted from tight lateral patellar retinaculum. The aim of our study is to compare between open and arthroscopic release of lateral patellar compression syndrome in relation of functional outcome, time of surgical procedure, length of hospital stays, intraoperative and postoperative complications as bleeding, infection, recurrence, and patellar instability with 2 years of follow-up.

Materials And Methods: 80 patients, age (21-49 years), were divided randomly into 2 groups (A and B).
