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

Managing skeletal metastatic disease can be a challenging task for the orthopedic surgeon. In patients who have poor survival prognoses or are poor candidates for extensive reconstructive procedures, management with intralesional curettage and stabilization with bone cement with or without internal fixation to prevent development or propagation of a pathologic fracture may be the best option. The use of bone cement is preferable over the use of bone graft, as it allows for immediate postoperative weight bearing on the affected extremity.This article describes a case where the combined use of arthroscopy and a 2-stage cementation technique may allow preservation of the articular surface and optimization of short-term functional outcome after curettage of a periarticular metastatic lesion in a patient with an end-stage malignancy. We used knee arthroscopy to identify any articular penetration or intra-articular loose bodies after curettage and initial cementation of the periarticular lesion of the distal femur. Arthroscopic evaluation was carried out again after the lesion was packed with cement to identify and remove any loose intra-articular debris. The applicability of this technique is broad, and it can be used in any procedure involving cement packing in a periarticular location. Performed with caution, this technique can be a useful adjunct to surgical management of both malignant and locally aggressive benign bone lesions in periarticular locations.
