Total knee arthroplasty with NexGen legacy posterior stabilized

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Reconstructive surgery

Background:

• Total knee arthroplasty (TKA) aims to restore pain-free movement for daily activities and leisure.
• Assessing long-term implant performance is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the 5-year clinical and radiographic performance of the NexGen Legacy Posterior Stabilised (LPS) system in TKA patients.
• To assess functional improvements and patient satisfaction after TKA.

Main Methods:

• Retrospective study of 94 patients (age 38-75) who underwent TKA with the NexGen LPS system.
• Inclusion criteria: osteoarthritis, rheumatoid arthritis, post-traumatic arthritis.
• Data collected via clinical assessment and radiographic analysis up to 5 years post-surgery.

Main Results:

• Significant improvement in Knee Society Score (60 to 85) and Knee Functional Score (55 to 100).
• No instances of patella clunk syndrome or patella dislocation reported.
• Positive clinical results align with international scoring systems after 5 years.

Conclusions:

• The NexGen LPS system demonstrates favorable clinical outcomes and patient satisfaction at 5-year follow-up.
• The system offers advantages compared to other contemporary TKA analogues.
• TKA with NexGen LPS effectively restores function and alleviates pain in diverse patient populations.
