Background:
For patients with advanced knee arthritis, general knee arthroplasty (TKA) is a commonly used technique to relieve aches and restore function. Although medial-pivot (MP) and post-stabilized (PS) implants are the various maximum widely used prosthetic designs, there is still confrontation over their relative efficacy and effect on affected person results.
Aim:
This examines the goal to systematically compare the medical and functional consequences of medial-pivot (MP) and Post-stabilized (PS) knee implants in sufferers undergoing general knee arthroplasty (TKA).
Methods:
The strategy for this systematic overview involved an in-depth literature search of the usage of databases, including PubMed, CINAHL, Embase, and the Cochrane Library, adhering to PRISMA recommendations. An overall of ten studies have been protected on this SRMA.
Results:
A total of ten studies were included in this analysis. Different variables were analyzed quantitatively for this study which includes WOMAC scores, KSS scores, OKS scores, and range of motion. The results of this meta-analysis showed that the tolerability of both of these methods was the same and no significant difference was observed between both groups. Data were extracted and a forest plot was made. The total effect was found to be 0.15 (-0.05, 0.35).
Conclusions:
We conclude that, although the medial-pivot (MP) prosthesis exhibits some advantages in knee kinematics and patient satisfaction, there is no statistically significant overall clinical superiority when compared to the Post Stabilized (PS) knee implants in total knee arthroplasty (TKA). This is based on a systematic review and meta-analysis. When it comes to reducing pain, enhancing range of motion, attaining radiographic alignment, and handling complications, both MP and PS prostheses are equally effective. This gives medical professionals practical choices that can be tailored to the specific surgical preferences and needs of each patient.
