Arthroscopically Assisted Two-stage Cementation Technique for a Periarticular Knee Lesion

Area of Science:

• Orthopedic Surgery
• Oncology
• Biomaterials

Background:

• Managing skeletal metastatic disease presents challenges, especially for patients with poor prognoses.
• Intralesional curettage and stabilization with bone cement offer an alternative to extensive reconstruction.
• Bone cement allows immediate postoperative weight-bearing, unlike bone graft alternatives.

Observation:

• A case report details using arthroscopy with a two-stage cementation technique for a periarticular metastatic lesion in the distal femur.
• Knee arthroscopy was employed post-curettage and initial cementation to assess articular penetration and loose bodies.
• A second arthroscopic evaluation confirmed removal of intra-articular debris after final cement packing.

Findings:

• The combined arthroscopy and cementation technique potentially preserves the articular surface.
• This method optimizes short-term functional outcomes in patients undergoing curettage of periarticular lesions.
• The technique is applicable to various periarticular procedures involving bone cement packing.

Implications:

• This technique serves as a valuable adjunct for surgical management of malignant and aggressive benign bone lesions in periarticular areas.
• It offers a method to improve outcomes in challenging orthopedic oncology cases.
• Cautious application is advised for optimal patient benefit.
