Arthroscopic partial meniscectomy.

OBJECTIVE

Excision of damaged meniscal tissue whereby the mechanical obstacles to joint movement are eliminated. As much functional, intact meniscal tissue should be retained as possible. Resection of only the bare minimum.

INDICATIONS: Symptomatic, irreparable lesions of the meniscus due to trauma or degeneration.

CONTRAINDICATIONS: Reparable lesions of the meniscus. Local skin affections.

SURGICAL TECHNIQUE: Introduction of the arthroscope through an anterolateral or central portal. The instrument portal is positioned in accordance with the situation of the meniscal lesion to be treated. The tissue to be excised is either broken into fragments with different punches or resected en bloc.

POSTOPERATIVE MANAGEMENT: Functional postoperative management without immobilization. Full loading on the leg.

RESULTS

Very good and good clinical results can be achieved in the short and long term after arthroscopic partial meniscectomy. In a study by Burks et al., 88% of 146 patients with stable knee joints had a very good or good result 14.7 years after partial meniscectomy. 95% of 57 patients were satisfied or very satisfied with the result 12 years after partial medial meniscectomy. A degenerative meniscal tear, axial deformity, higher age, and anterior cruciate ligament insufficiency are factors associated with an increased rate of arthrosis in the long term.
