The goal of this clinical trial is to compare different peri-incisional local infiltrative anesthesia (PLIA) methods in patients ages 13 to 50 undergoing a periacetabular osteotomy (PAO). The main questions to answer here are:

1. Does PLIA impact post-operative pain after PAO?
2. Does PLIA impact pain medication usage as measured by morphine equivalent dosing (MED) after PAO?
3. Does the timing of PLIA administration impact post-operative pain and MED after PAO? Participants will be asked to complete some surveys; demographics survey, General Self-Efficacy Scale (GSE) and the Pain Resilience Scale. All other information will be gathered from the patients medical chart.

Researchers will compare three groups. 1.) Patients who do not receive PLIA. 2.) Patients who receive PLIA after their incision is closed. 3.) Patients who receive PLIA throughout PAO.

This study is being done to find out if metformin is effective at reducing pain by delaying the onset of post-traumatic osteoarthritis (PTOA) after anterior cruciate ligament (ACL) reconstruction. This research study will compare metformin to placebo. The placebo tablet looks exactly like metformin, but contains no metformin. Placebos are used in research studies to see if the results are due to the study drug or due to other reasons.

Metformin is approved by the U.S. Food and Drug Administration (FDA) to treat type II diabetes. Notably, it also has anti-inflammatory effects, suggesting it could benefit people who have an ACL injury and are undergoing ACL reconstruction.

This initial study is a feasibility study for implementing thoracolumbar interfascial plane, or TLIP, blocks in older adults undergoing spinal fusion. TLIP blocks are done by using anesthesia. In this case, it will be done to either side of the back where surgery will be performed. This has been shown to decrease pain the patients have post-operatively in previous research. In this study, the investigators will examine recruitment rates, completion of assessments, dropout rate, gather patient feedback, and identify barriers to performing TLIP. Further, this feasibility study will provide data to determine adequate sample size and refine methods and outcomes for a future randomized clinical trial. The ultimate goal is to perform a large, appropriately powered randomized control trial to determine the effect of TLIP blocks on pain, physical function and disability, opioid consumption, and delirium in older adult undergoing spinal fusion.

The goal of this clinical trial is to examine the effect of a single autologous, intra-articular injection of MFat versus corticosteroid injection for the treatment of pain and function associated with K/L grade 2/3 knee Osteoarthritis.

Participants will receive an injection of MFat or a corticosteroid.

This is a study comparing two methods of dressing a post operative wound that are currently in practice. One method is a traditional dry gauze dressing. The other method is using a negative pressure dressing that provides gentle suction on the wound.

The investigators will attempt to determine how well the use of post-operative negative pressure dressing reduces wound healing problems in patients who have surgery after radiation for a sarcoma in the thigh or leg.
