Following treatment for a primary extremity sarcoma, patients remain at risk for the development of local and systemic disease recurrence. Metastasis (distant recurrence) to the lung is the most frequent single location of disease recurrence in sarcoma patients, occurring in almost half of all patients. Therefore, careful post-operative surveillance is an integral element of patient care. However, the detection of metastases does not necessarily affect long-term survival and may negatively impact quality of life. Surveillance strategies have not been well researched and have been identified as the top research priority in the extremity sarcoma field. Using a 2X2 factorial design to maximize efficiency and reduce overall trial costs, the SAFETY trial will randomize 830 extremity soft-tissue sarcoma (STS) patients to determine the effect of surveillance strategy on overall patient survival after surgery for a STS of the extremity by comparing the effectiveness of both surveillance frequency (every 3 vs. every 6 months) and imaging modality (CT scans vs. chest radiographs).

Tranexamic acid and placebo will be given during surgery to patients who have elected to undergo lumber interbody fusion on 2 or more levels. Information regarding blood loss, transfusions needed, postoperative cognitive status (including delirium), postoperative markers of systemic inflammation and duration of hospital stay will be collected.

Rotator cuff tears are one of the most common reasons to seek musculoskeletal care in the United States and one of the fastest growing ambulatory surgery procedures. However, data on comparison of operative versus non-operative treatment is lacking and urgently needed.

The purpose of the clinical study is to investigate whether the local delivery of bisphosphonate as a surgical adjuvant can decrease the chance of a giant cell tumor of bone coming back to the same location. The hypothesis is that the local administration of bisphosphonate will decrease the rate of the tumor returning compared to traditional aggressive surgical removal of the tumor.

The purpose of this study is to compare the outcomes of two different treatment options commonly used to manage periprosthetic joint infection (PJI), an infection around the artificial knee or hip.

The purpose of the current investigation is to assess the safety and efficacy of a new hinged revision knee device. This device is designed to provide efficient, reproducible reconstructions with optimal limb and implant alignment, durable implant fixation, and functional outcomes that increasingly approach those of primary Total Knee Arthroplasty (TKA).
