Total knee arthroplasty following patellectomy.

O Bayne, H U Cameron

    Clinical Orthopaedics and Related Research
    |June 1, 1984
    PubMed
    Summary

    Prior patellectomy can lead to persistent pain after total knee arthroplasty. Prosthetic choice is key, with hinged implants showing better outcomes in these complex cases.

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering
    • Reconstructive Surgery

    Background:

    • Prior patellectomy presents unique challenges in total knee arthroplasty (TKA).
    • Patients may experience persistent pain and instability post-TKA after patellectomy.
    • Assessing outcomes in TKAs with prior patellectomy is crucial for improving patient results.

    Purpose of the Study:

    • To evaluate the outcomes of total knee arthroplasty in patients with a history of patellectomy.
    • To determine the influence of prosthetic design on functional stability and pain.
    • To identify optimal implant strategies for this patient subgroup.

    Main Methods:

    • Retrospective review of 17 patients who underwent TKA with prior patellectomy.
    • Analysis of 14 available cases, including one fusion for infection and six revisions for pain.
    • Correlation of clinical outcomes with prosthetic type: hinged, unlinked, and semiconstrained.

    Main Results:

    • Hinged prostheses (5 cases) demonstrated good outcomes.
    • One of two unlinked hinges yielded good results.
    • Two of six semiconstrained prostheses had acceptable results, indicating variable performance.
    • Prosthetic intrinsic stability was a key factor in successful outcomes.

    Conclusions:

    • The integrity of the patellar mechanism and cruciates is vital for knee stability.
    • For patients with compromised patellofemoral function post-patellectomy, prostheses with inherent anteroposterior stability are recommended.
    • Careful selection of implant type is essential for managing pain and instability in TKAs following patellectomy.
