TKA results are not compromised by previous arthroscopic procedures

Area of Science:

• Orthopedic Surgery
• Knee Arthroplasty
• Arthroscopic Procedures

Background:

• Previous arthroscopic knee procedures are common before total knee arthroplasty (TKA).
• The impact of multiple prior arthroscopic interventions on TKA outcomes remains a clinical question.

Purpose of the Study:

• To evaluate if a history of two or more arthroscopic procedures affects total knee arthroplasty (TKA) outcomes.
• To compare clinical results and implant survivorship in TKAs following multiple arthroscopies versus primary TKAs.

Main Methods:

• Retrospective comparison of 62 knees with ≥2 prior arthroscopic procedures to 438 knees with no prior surgery.
• Clinical outcomes assessed using Knee Society objective and function scores.
• Implant survivorship evaluated with revision for aseptic component failure as the endpoint.

Main Results:

• Implant survivorship was high and comparable in both groups (98%).
• The post-arthroscopy group demonstrated significant improvements in Knee Society objective (92 points) and function (89 points) scores.
• Radiographic analysis revealed no significant differences between the cohorts.

Conclusions:

• Multiple prior arthroscopic knee procedures do not appear to negatively influence TKA outcomes.
• Patients can expect comparable clinical results and implant longevity after TKA, irrespective of prior arthroscopic interventions.
