Abstract

Fat pad hypertrophy, degeneration and scar tissue at the anterior knee in Taekwondo athletes can occur due to repetitive training such as kicking. This scar tissue can cause pain at the anterior compartment of the knee joint by impingement during knee flexion and extension. We obtained good results for treating anterior impingement syndrome by performing arthroscopic resection, and we also report on the relevant medical literature.

Figures and Tables

Figure 1

Case 1. Sagittal (A) and coronal (B) T2-weighted MR images show intermediate signal intensity mass anterior to tibial attachment site of anterior cruciate ligament (ACL) and intercondylar notch.

Figure 2

(A) Hypertrophied fibrous scarring was found at anterior portion of ACL tibial attachment site. (B) Arthroscopic finding after resection of scar tissue.

Figure 3

(A) (B) Case 1. MR images taken 20 months after surgery show disappearance of mass compared with preoperative MR.

Figure 4

Case 2. Sagittal (A) and coronal (B) T2-weighted MR images show low-intermediate signal intensity mass anterior to tibial attachment site of ACL.

Figure 5

Avascular scar formation anterior to ACL tibial insertion site (A) was removed arthroscopically (B).

Figure 6

Sagittal (A) and coronal (B) T2-weighted MR images taken 17 months after surgery show disappearance of scar tissue compared with preoperative MR.
