Abstract
Aim: Evaluation of clinical and radiological outcomes following meniscal repair using different arthroscopic techniques for all meniscal tears amenable for repair. Methods: Sixty-one patients were involved in a prospective study; all cases presented with meniscal tears underwent arthroscopic meniscal repair from December 2016 to December 2017. Outcomes involved the site of tear, the repair technique, and associated injuries. The International Knee Documentation Committee Score (IKDC) and Tegner Lysholm Knee Score were used to analyze the clinical and functional outcomes postoperatively. Results: Of the 61 patients, 50 patients (81.9%) had meniscal tear associated with isolated ligamentous ACL injury, 6 cases had corrective osteotomy with ACL reconstruction to correct concomitant genu varus, 2 cases (3.3%) had meniscal tear associated with isolated ligamentous PCL injury, and 9 patients (14.8%) presented with isolated meniscal tear; IKDC was preoperatively (44.52 ± 8.79), postoperatively at 6 months (90.97 ± 6.75) and at 12 months (92.27 ± 2.68) with P-value (0.001). Tegner Lysholm score was preoperatively (52.16 ± 12.22), postoperatively at 6 months (88.03 ± 6.84) and at 12 months (93.26 ± 2.95) with P-value (0.001). Fifty eight patients (95.1%) had no postoperative symptoms at 6 and 12 months’ follow-up. The remaining 3 cases (4.9%) underwent partial meniscectomy due to persistent postoperative clinical symptoms with no signs of healing in MRI. Conclusions: Our study concluded that arthroscopic meniscal repair is an effective way in the management of meniscal tears regarding clinical and functional outcomes.
Highlights
The meniscus plays an important role in knee function by providing structural and biomechanical roles in congruence, joint load distribution and bearing, stability, lubrication, proprioception, and nutrition [1]
Most of meniscal tears are treated by arthroscopic repair; common criteria of the meniscal tear that are amenable for repair include: a tear within 3–4 mm of the meniscocapsular junction or the peripheral 10% to 30% of the meniscus, complete vertical tear >10 mm, a tear without secondary degenerative diseases or deformity, a symptomatic tear in young patients, and a tear without multiligamentous injury or stable knee
Fifty-two patients (85.2%) had meniscal tear associated with isolated ligamentous injury (ACL or PCL)
Summary
The meniscus plays an important role in knee function by providing structural and biomechanical roles in congruence, joint load distribution and bearing, stability, lubrication, proprioception, and nutrition [1]. Most of meniscal tears are treated by arthroscopic repair; common criteria of the meniscal tear that are amenable for repair include: a tear within 3–4 mm of the meniscocapsular junction or the peripheral 10% to 30% of the meniscus, complete vertical tear >10 mm, a tear without secondary degenerative diseases or deformity, a symptomatic tear in young patients, and a tear without multiligamentous injury or stable knee. When these criteria are present, formal repair using a variety of methods should be conducted [4]
