3. Fig 2
Arthroscopic picture of the left knee in supine position with the knee flexed to 90°. Viewing from the camera in the anterolateral portal, the location of the low and high posteromedial portal is shown (green and blue star, respectively). (MFC, medial femoral condyle; PHMM, posterior horn of the medial meniscus; PM, posteromedial.)

4. Fig 3
Comparison of the visualization of the posterior horn of medial meniscal capsular lesion (star) of the left knee between the arthroscope from the anterolateral portal (A) and the posterolateral portal (B). (MFC, medial femoral condyle; PHMM, posterior horn of the medial meniscus; PM-Cap, posteromedial capsule.)

5. Fig 4
The outside picture when working from the posterior compartment of the left knee. The camera was placed in the posterolateral portal for viewing (thin arrow), and the cannula was placed in the high posteromedial portal (thick arrow); the inset shows the motorized shaver through the low posteromedial portal (star). (MFC, medial femoral condyle; PHMM, posterior horn of the medial meniscus; PM-Cap, posteromedial capsule.)

6. Fig 5
With the camera in the posterolateral portal (thin arrow), the inset shows that the suture hook device was inserted from the low posteromedial portal (star) and passed from posterior to anterior of the tear site. Note that the thick arrows (both inside and outside views) are the first suture that was already passed through the meniscal fragment beginning from the medial site and temporarily kept in the low posteromedial portal. (MFC, medial femoral condyle; PHMM, posterior horn of the medial meniscus; PM-Cap, posteromedial capsule.)

7. Fig 6
Arthroscopic knot pusher was used to tie the knot from the lateral to medial direction in the cannula from the high posteromedial portal (thick arrow). Note that the camera was always placed in the posterolateral portal during the repair process (thin arrow). The inset shows that the first pair of suture that was tied is the most lateral one, whereas the other pairs were kept in the low posteromedial portal (star). (MFC, medial femoral condyle; PHMM, posterior horn of the medial meniscus; PM-Cap, posteromedial capsule.)
