Randomized Controlled Trial
Preoperative Femoral Nerve Block for Hip Arthroscopy: A Randomized, Triple-Masked Controlled Trial.
Arthroscopy has become a standard method of treatment for a variety of intra-articular hip disorders. While most arthroscopic hip procedures are performed as outpatient surgeries, patients can still experience significant postoperative pain and opioid-associated side effects. ⋯ Preoperative FNB may improve early pain control after hip arthroscopy. However, given the observed risk of falls, the routine use of FNB for outpatient hip arthroscopy cannot be recommended.

Randomized Controlled Trial
Reducing Intra-articular Hemarthrosis After Arthroscopic Anterior Cruciate Ligament Reconstruction by the Administration of Intravenous Tranexamic Acid: A Prospective, Randomized Controlled Trial.
A significant proportion of surgeons use intra-articular drains after arthroscopic anterior cruciate ligament (ACL) reconstruction. Hemarthrosis and pain adversely affect the functional outcomes of ACL reconstruction in the early postoperative period. ⋯ The results of this prospective, randomized study show that TXA reduced the amount of postoperative hemarthrosis and decreased the need for aspiration of the knee after arthroscopic ACL reconstruction. Consequently, TXA reduced pain and improved range of motion of the knee in the early postoperative period without side effects.

Randomized Controlled Trial
Efficacy of the FIFA 11+ Injury Prevention Program in the Collegiate Male Soccer Player.
The Fédération Internationale de Football Association (FIFA) 11+ program has been shown to be an effective injury prevention program in the female soccer cohort, but there is a paucity of research to demonstrate its efficacy in the male population. ⋯ The FIFA 11+ significantly reduced injury rates by 46.1% and decreased time loss to injury by 28.6% in the competitive male collegiate soccer player (rate ratio, 0.54 [95% CI, 0.49-0.59]; P < .0001) (number needed to treat = 2.64).

Comparative Study
Comparative Matched-Pair Analysis of the Injection Versus Implantation of Mesenchymal Stem Cells for Knee Osteoarthritis.
The mesenchymal stem cell (MSC)-based tissue engineering approach has been developed to address the problem of articular cartilage repair in knee osteoarthritis (OA). However, the most effective method of MSC application has not yet been established. ⋯ Utilizing the described method, MSC implantation for knee OA resulted in better clinical and second-look arthroscopic outcomes than an MSC injection.

Young athletes who have had anterior cruciate ligament (ACL) reconstruction demonstrate suboptimal rates of return to sport, high rates of second ACL injuries, and persistent movement asymmetries. Therefore, the influence of musculoskeletal impairments on movement mechanics in this population needs to be further evaluated. ⋯ Restoration of symmetric quadriceps strength after ACL reconstruction is associated with more symmetric mechanics during a single-leg drop-landing movement. However, this appears to be multifactorial, as the high-quadriceps group also demonstrated landing asymmetries. Restoration of symmetric quadriceps strength may improve postoperative athletic participation; however, future study is warranted.
