Filter by:In recent years, short femoral stems have been introduced. Short stems are designed based on traditional stems with good clinical results. The assumed benefit of short stems is that they are easier to use in mini-invasive surgery, and that preservation of proximal periprosthetic bone stock is better. Preservation of periprosthetic bone in the proximal femur is thought to secure long time anchoring of the implant, and reduce the risk of loosening. In addition, a good proximal bone stock makes later revision surgery less technically demanding. However, the short stem design could compromise the stability of the prosthesis, and there has been reported diverging results regarding correct positioning of short stems. This may be due to the lack of inherent aiming provided by the tip of the traditional long stems. We want to clinically evaluate the stability and bone remodelling pattern of a new short femoral stem based on a standard stem with excellent long time results. In addition we will compare the two different stems regarding positioning, when using a newly developed guiding broach for the short stem, and the standard broach for the long stem. Finally, patient reported clinical outcome scores will be evaluated with respect to implant and biomechanical reconstruction. The aim of this study is to evaluate whether this specific short femoral stem is stable, safe to use, and if it provides the expected beneficial effects on bone remodelling.
Hip osteoarthritis (HOA) is a common cause of pain and disability in aging population. Conservative treatment is based on lifestyle modifications, physical therapy, analgesic and anti-inflammatory medications and intra articular injections. This Prospective Pilot Study aims at investigating the efficacy of Ultrasound-Guided Cooled Radiofrequency Hip Denervation as a treatment offered to patients with HOA.
To pilot test an activity-focused intervention that educates patients undergoing total hip (THA) or total knee (TKA) arthroplasty due to osteoarthritis about the appropriate type, frequency, intensity, and duration of expected leisure activities after surgery and to determine if the intervention changed expectations.
The investigators propose to evaluate and compare the percentage of patients who are able to be discharged in less than 3 days after undergoing total hip arthroscopy through either a direct anterior or posterior approach, utilizing the identical post operative protocol. The investigators also propose to evaluate the costs associated with the two different approaches to hip replacement in the same group of patients. Post operative resource utilization, discharge disposition, and pain medicine requirement will also be evaluated.
The specific aim is to quantify the stability of the acetabular and femoral components of a revision total hip arthroplasty (THA) in vivo as currently performed at our institution. In this way, the investigators will gain insight into the outcome of the current state of the art of revision arthroplasty surgery. In the past, acetabular and femoral component stability has been measured using radiostereometric analysis (RSA) and when patients having revision total hip operations were compared to patients undergoing primary total hip operations it was possible to determine differences in stability and this was predictive of the intermediate to long-term performance of the acetabular and femoral reconstruction. The investigators propose to use this established, high resolution technique to assess and compare the stability of the revision implants.
The purpose of this study is to see if using a device called the Resonator, that puts out very low level electromagnetic fields will help symptoms of painful hip(s)
Retrospective Data Review on clinical outcomes and survivorship of ReCap Total Hip Resurfacing
In this study, a functional evaluation of total knee arthroplasty (TKA) patients is performed. The patients are measured prior to surgery and 6 and 12 months after surgery. The measurements consist of questionnaires and rising from a chair. Also, two types of TKA are functionally evaluated. At last, the TKA group will be compared to a THP group.
