Background: Repair of a meniscal tear is indicated in certain conditions. Despite extensive research on the biomechanics of various repair methods, there has been minimal investigation of whether the suture material influences the meniscal-suture construct. The purpose of this study was to compare the biomechanical properties of nine different suture materials under cyclic and load-to-failure conditions. Methods: Ninety porcine menisci were randomly allocated to simple suture placement using either Ultrabraid®, Ultratape® , Magnum Wire®, TigerWire®, TigerTape®, LabralTape®, Orthocord®, 0 FiberWire®, or 2-0 FiberWire®. Each suture-meniscus specimen underwent cyclic loading followed by load-to-failure testing. Elongation, maximum load to failure, stiffness, and mode of failure were recorded and compared between each suture type using nonparametric testing. Mean ± standard deviation was reported and the statistical significance was p < 0.05. Results: Elongation during cyclic loading was lowest with 2-0 FiberWire (0.95 ± 0.17 mm); this value was statistically significantly different than the results for all other sutures except 0 FiberWire® (1.09 ± 0.17 mm, p = 0.79), TigerWire® (1.09 ± 0.29 mm, p = 0.85), TigerTape® (1.39 ± 0.29 mm, p = 0.08), and LabralTape® (1.20 ± 0.33 mm, p = 0.41). The highest elongation was seen with Ultrabraid® (1.91 ± 0.34 mm); this value was statistically significantly greater than the results for all other suture materials except Orthocord® (1.59mm± 0.31 mm, p = 0.46) and Magnum Wire® (1.43 ± 0.25 mm, p = 0.14). Load to failure was highest for TigerTape® (287.43 ± 41.15 N), and this result was statistically significantly different than the results for all other sutures except LabralTape® (271.34 ± 48.48 N, p = 0.99) and TigerWire® (251.03 ± 25.8 N, p = 0.51). Stiffness was highest for LabralTape® (195.77 ± 49.06 N/mm), and this result was statistically significantly different than the results for all other sutures except TigerWire® (186.49 ± 19.83 N/ mm, p = 0.45) and TigerTape® (173.35 ± 15.60 N/mm, p = 0.19). The majority of sutures failed by pullout (n = 46, 51%) or tearing (n = 40, 45%). Conclusion: Suture design and material affect the biomechanical behavior of porcine meniscal-suture specimens. LabralTape®, TigerWire®, and TigerTape® demonstrated better overall combinations of low elongation, high maximum load to failure, and high stiffness.

Purpose: Osteochondral allograft (OCA) transplantation is a restorative technique for addressing articular cartilage defects by transferring mature viable chondrocytes with subchondral bone into size-matched lesions. The purpose of this study was to compare differences in clinical and functional outcomes in patients treated with OCA for osteochondral defects compared with isolated chondral pathology. Methods: A retrospective review identified patients who underwent OCA transplantation and grouped them into osteochondral or isolated chondral pathology. Demographic data, surgical history, lesion characteristics, complications, and rate of subsequent surgery were reviewed. The review included 86 patients (24 osteochondral, 62 chondral) with a mean follow-up of 5.4 ± 1.4 years. Outcome measures included the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR.), International Knee Documentation Committee (IKDC), and Short Form Health Survey (SF-12) physical scores. Failure was defined to include revision OCA, graft removal, conversion to ACI, or conversion to arthroplasty. Results: The average age at surgery was 32.3 and 37.3 years for the osteochondral and chondral groups, respectively (P = 0.056). The medial femoral condyle was the most common defect location in both groups. P < 0.05 was considered statistically significant. Patients with osteochondral pathology had significantly greater KOOS JR., IKDC, and SF-12 scores (P < 0.05), and fewer failures were reported in the osteochondral group (8.3% versus 32.3%, P = 0.045). When controlling for age, sex, laterality, BMI, and presence of a concomitant procedure, patients with osteochondral pathology were found to have better KOOS and IKDC scores, but there was no difference in SF12 scores or rates of failure between groups. Conclusion: The findings of this study indicate that patients undergoing OCA for osteochondral defects may have greater functional outcomes and similar failure rates compared with OCA transplantation for isolated chondral pathology.
