There is growing, strong evidence that unicompartmental knee replacement (UKR) can have many advantages for patients over total knee arthroplasty (TKA).

One of the possible consequences of total knee arthroplasty (TKA) can be popliteus tendon impingement which, although rare, results in significant pain for some patients.

Similar migration and patient-reported outcome measures (PROMs) for medial congruent (MC) and cruciate‑retaining (CR) tibial components.

Instability after total knee arthroplasty is a common but poorly understood complication and very often leads to revision surgery to help correct the instability that may have built up over time, following the initial procedure.

This 2022 study examined the tibiofemoral kinematics and patient outcomes of knee replacement surgery using two different implants – the medial congruent (MC) bearing and the cruciate retaining (CR) bearing.

Novice surgeons who listen to AC/DC may be faster while maintaining accuracy during laparoscopic surgery.

New figures reveal a triple-digit percentage point rise in patients paying out of their own pockets, when comparing July to September 2019 figures against the same period in 2021.

Conventional total knee arthroplasty (TKA) replacement studies have shown that pain, instability and limitation of the range of motion are the most commonly reported symptoms among unsatisfied patients. The major cause of unsuccessful TKA are inadequate alignment and errors in balancing.

While often successful in reducing pain, improving knee function and therefore quality of life, TKR does not necessarily restore full range of motion of the pre-operative joint.

Unicompartmental Knee Arthroplasty (UKA) is a less invasive alternative to total knee arthroplasty (TKA) for the treatment of end-stage arthritis^1-4. 

This study was undertaken to evaluate the safety of a same-day surgery protocol using the partial knee replacement (PKR).

Based on meta-analysis of 52 articles and more than 4,500 patients, the mini-subvastus approach for TKA demonstrated superior overall, when compared to the others.
