Background: The purpose of this study was to introduce a new technique for arthroscopic partial meniscectomy of the medial meniscus posterior horn (MMPH) in tight knees.
Methods: We briefly compared clinical results and complications between the group of conventional technique and piecrust method at more than postoperative 2 years.
Results: In the conventional group (30 patients), mean Lysholm knee scores improved from 72.5 (range, 68 to 88) preoperatively to 94.5 (range, 78 to 98) at final follow-up (P < 0.01), and the mean preoperative Hospital for Special Surgery (HSS) scores improved from 82.3 (range, 69 to 91) to 95.9 (range, 87 to 98) at final follow-up (P < 0.01). In the piecrust group (30 patients), mean Lysholm knee scores improved from 76.5 (range, 58 to 91) preoperatively to 93.5 (range, 74 to 97) at final follow-up (P < 0.01), and the mean preoperative HSS scores improved from 78.3 (range, 64 to 88) to 94.9 (range, 85 to 96) at final follow-up (P < 0.01). However, there was no significant difference between two groups with final follow-up scores (P = 0.23).
Conclusion: Under the basis of discussed points, the “pie-crusting” technique can be helpful for partial arthroscopic meniscectomy of the MMPH in tight knees.
