[PDF] The routine of surgical management reduces failure after unicompartmental knee arthroplasty. | Semantic Scholar (2024)

Compartmental arthritis forms a significant subgroup of patients presenting with osteoarthritis of the knee, and resurgent interest in compartmental arthroplasty is based on encouraging reports from those few centres which have pioneered the treatment.

For the majority of patients, UKA provides reliable and reproducible results, however, USA is a demanding procedure that needs special experience and includes a risk of early failure.

The results show that an independent center can achieve excellent long-term clinical and survival results in patients implanted with the Oxford prosthesis, and survival of the implant was not reduced by the use of thin polyethylene bearings.

Early experience is presented including indications and selection criteria, surgical planning, step-by-step technique description, postoperative management, and early results of unicompartmental replacement.

The clinical relevance of this study is that the captive running track of the LCS mobile-bearing prosthesis may over constrain the meniscal component leading to early failure.

Mobile bearing UKA seems to be less appropriate for the Asian population as extreme knee flexion is required for cultural purposes, and a pooled analysis of the reported cases provided an evidence-based summarisation.

Unicompartmental knee arthroplasty with the Marmor/Mod 2 prosthesis has provided satisfactory long-term durability in this cohort of elderly patients, in comparison with similar published studies featuring other prostheses.

The ten-year survival rate is the best of those reported for unicompartmental arthroplasty and not significantly different from the best rates for total knee replacement.

The Oxford Knee, a resurfacing prosthesis with a meniscal bearing, can be used for either bicompartmental or unicompartmentsal arthritis and stability and alignment were restored to normal in nearly all the knees.

It was found that operations for osteoarthrosis (OA) counted for the increase in number of arthroplasties in contrast to rheumatoid arthritis (RA), where the number had slightly declined, and that failed unicompartments were best replaced with a tricompartmental prosthesis.

In uncemented THRs, survival results were similar in central and local hospitals, whereas the adjusted revision rate at university hospitals was 1.6 (CI: 1.13-2.19) times that of local hospitals.

The need to present confidence intervals has recently been discussed at meetings of The American Academy of Orthopaedic Surgeons, in an editorial in The Journal of Bone and Joint Surgery, and in a recent survivorship analysis of the total condylar kneearthroplasty prosthesis.

The Patient Administrative System (PAS), a database based on ICD coding and run by the Swedish health authorities, could be used to locate missing revisions found by the postal survey and it is estimated that 94% of all revisions are accounted for.
