Perfusion Assessment of Wound Closure Techniques in Primary Total Knee Arthroplasty

Study type:
Interventional
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

This study will assess which of the three most common methods of wound closure in primary total knee arthroplasty (staples, interrupted vertical mattress, or running subcuticular suture) provide the best wound vascular perfusion. This can be achieve by using SPY intra-operative vascular angiography, which is commonly used in clinical practice to assess perfusion of wound closure at the clinic. By understanding the differences in perfusion afforded by different closure techniques, surgeons will then be able to select the technique that optimizes this parameter so as to avoid complications such as tissue necrosis, wound dehiscence, or infection.

Neurotransmitter Measurements Using Wireless Instantaneous Neurotransmitter Concentration System (WINCS) During Deep Brain Stimulation Neurosurgery

Study type:
Interventional
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
Study phase:
1
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

In this study, the investigators will monitor extracellular neurotransmitter levels using a probe that is able to perform real time electrochemical detection during deep brain stimulation surgery. The overall question this study is designed to answer is: Are there neurotransmitters released during deep brain stimulation?

About this study

Corticosteroid injections are commonly used for the symptomatic treatment of knee osteoarthritis. Common practice is to inject the joint with a combination of corticosteroid and local anesthetic, with the rationale of providing longer duration pain relief with the corticosteroid and immediate, though short duration relief with the anesthetic. However, multiple in vitro and animal studies have shown that local anesthetic may be harmful to chondrocytes. Despite this data, use of intra-articular anesthetic remains widespread. Many clinicians believe incorporating the anesthetic is important because it can provide immediate pain relief and facilitate patient confidence in the treatment program. However, there is no published data to validate this reasoning. Therefore, the anesthetic has unknown clinical benefit and may have adverse effects on articular cartilage. In light of this, the investigators question the routine use of anesthetics in joint injections. The purpose of this study is to compare the effects of knee joint injections using: 1) corticosteroid with local anesthetic versus 2) corticosteroid with normal saline.
