    Summary

    Total knee replacement complications were reviewed in 162 patients. Patellofemoral pain and arthritis were the most common and disabling issues following knee surgery.

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering

    Background:

    • Total knee replacement (TKR) is a common procedure for end-stage knee arthritis.
    • Complications can impact patient outcomes and implant longevity.

    Purpose of the Study:

    • To identify and quantify early and late complications following total knee replacement.
    • To determine the incidence of various adverse events in a large patient cohort.

    Main Methods:

    • Retrospective review of medical records and radiographs.
    • Analysis of 224 total knee replacement cases in 162 patients.
    • Categorization of complications into early and late events.

    Main Results:

    • Early complications included deep vein thrombosis (3%) and limited motion requiring manipulation under anesthesia (7%).
    • Late complications observed were patellofemoral arthritis (11%), heterotopic ossification (10%), loosening (7%), deformity (4%), fracture (3%), and infection (2%).
    • Patellofemoral pain and arthritis emerged as the most frequent and disabling complication.

    Conclusions:

    • Total knee replacement is associated with a range of early and late complications.
    • Patellofemoral issues represent a significant challenge in TKR outcomes.
    • Monitoring and management strategies for patellofemoral complications are crucial for improving patient function after TKR.
