Randomized Controlled Trial Multicenter StudyDid Osteoblastic Cell Therapy Improve the Prognosis of Pre-fracture Osteonecrosis of the Femoral Head? A Randomized, Controlled Trial.
In patients with nontraumatic osteonecrosis of the femoral head (ONFH), implantation of bone marrow aspirate concentrate (BMAC) could delay the progression of osteonecrosis and improve symptoms in pre-fracture ONFH. However, the BMAC content, especially in osteoblastic stem cells, could have an important individual variability. An autologous osteoblastic cell product could improve the effect of such cell-based therapy. ⋯ Level II, therapeutic study.

Randomized Controlled Trial Comparative StudyDoes Robotic-assisted TKA Result in Better Outcome Scores or Long-Term Survivorship Than Conventional TKA? A Randomized, Controlled Trial.
Robotic-assisted TKA was introduced to enhance the precision of bone preparation and component alignment with the goal of improving the clinical results and survivorship of TKA. Although numerous reports suggest that bone preparation and knee component alignment may be improved using robotic assistance, no long-term randomized trials of robotic-assisted TKA have shown whether this results in improved clinical function or survivorship of the TKA. ⋯ Level I, therapeutic study.

Randomized Controlled TrialThe "Cough Trick" Reduces Pain During Removal of Closed-suction Drains after Total Knee Arthroplasty: A Randomized Trial.
Drain removal after TKA can be painful. Prior research suggests that the "cough trick," in which a patient coughs at the same time she or he receives an injection, effectively decreases pain. To our knowledge, this intervention has not been evaluated as a way to reduce pain during other brief but painful interventions, such as removal of closed-suction drains after orthopaedic surgery. ⋯ Level I, therapeutic study.

Randomized Controlled TrialDoes an Elastic Compression Bandage Provide Any Benefit After Primary TKA?
Compression bandages often are used after TKA to reduce swelling. However, the degree to which they are helpful has not been well characterized. ⋯ Level I, therapeutic study.

Randomized Controlled TrialNo Clinically Important Difference in Pain Scores After THA Between Periarticular Analgesic Injection and Placebo: A Randomized Trial.
Periarticular analgesic injection (PAI) is being used more commonly for pain relief after orthopaedic surgeries. However, there is conflicting evidence regarding the effectiveness of PAI for post-THA pain relief. ⋯ Level I, therapeutic study.
