Filter by:The regime in the aftercare after total hip and knee arthroplasty(THA/TKA) differs a lot between orthopedic surgeons concerning weight bearing. The type of implant and the way of implants' anchoring are considered. In the literature there is no data so far about the way patient take care of the recommended weight bearing during the first 6 weeks after THA and TKA. Over a one year period starting August 2010 all patients undergoing TKA or THA at the investigators institution will have a technical device in their shoes (sole) to measure the load in each step they do in these shoes during the first 6 weeks. Patients are asked to fill out a standardised pain protocol every day (VAS) and document need of pain medication. The investigators recommend 20kg of weight on the operated leg for 6 weeks and full weight bearing at the end of week six. The investigators believe that patients will adjust weight bearing to their level of pain and not to their surgeons recommendations.
The primary objectives of this clinical study include: - Assess the rate of dislocation and fracture of THA using the new (the 4th generation) ceramic implants. - Evaluate the survival rate of THA using the new alumina-zirconia (the 4th generation) composite ceramic bearing. - Investigate the performance of the 4th generation ceramic implants mostly in patients younger than 50 years. - Compare the preoperative and postoperative scores of Harris Hip Score, UCLA Activity Score and WOMAC.
The randomised controlled trial will be carried out on patients that require a total hip replacement (THR) to reduce pain and restore their function. One way of fixing the hip joint to the bone is by coating the implant to encourage the body to grow bone onto the replacement hip. This study is aiming to find out whether the new (Bonemaster) coating allows increased bony growth onto the cup when compared to the usual (plasma-sprayed) coating. This may reduce the incidence of early failures due to poor bony attachment, which is a well known complication for early failure of total hip replacements. The study will compare two different types of coating (BoneMaster and Plasma-sprayed) on the cup of the replacement hip. Density of the bone immediately surrounding the cup will be observed to see if there are differences between the two groups. The density of bone will be measured using standard x−ray assessment and in a smaller sample of 14 patients, using a special scan called Dual Energy X−ray Absorptiometry (DEXA Scan). Functional comparisons will be assessed through clinical scores.
