The purpose of this study is to determine when patients have returned to driving a car following total joint arthroplasty and whether or not they were involved in a car accident after their return to driving.

Does having a large diameter metal on polyethylene total hip replacement increase metal ion release? Larger metal heads are thought to have increased torsional forces on the trunion which would like release more metal ions. Increased metal ion levels have been associated with adverse local tissue reactions. Are there any differences comparing these groups to a dual mobility type total hip replacement.

This is a prospective clinical trial examining only subjects who undergo THA with PSI. The purpose of this study is to compare the alignment accuracy of patient-specific implants versus traditional off-the-shelf implants in total hip arthroplasty using prior literature-derived data as controls.

The purpose of the study is to determine the survivorship, clinical outcomes, and mechanisms of failure associated with total hip and knee arthroplasty in patients with osteogenesis imperfecta.

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.

The purpose of this study is to:

• Determine patient reported outcomes following total hip arthroplasty based on surgical approach.
• Determine if the Forgotten Joint Score (FJS)-12 has superior capability to discriminate outcomes in patients with THA compared to the modified Harris Hip Score (mHHS).

Of the three most commonly/routinely performed surgical technique of patellar resection during total knee arthroplasty performed at the Mayo Clinic, which results in the most symmetrically resected patella (knee-cap)?

The purpose of this study is to determine the rate of hardware removal, the clinical outcomes of hardware removal, and patient satisfaction after hardware removal after Bernese PAO. 
 

The purpose of this study is to determine the prevalence of groin pain after total hip arthroplasty (THA) with a dual-mobility cup, and to compare this rate of groin pain to patients who receive standard THA components.
