Abstract

Objective: After traumatic knee injuries, chondral fragments can avulse off bone with the progeny fragment becoming a loose body. The loose fragment may be larger than expected when trying to surgically repair the fragment back to its original site. The purpose of this study was to determine whether a loose chondral fragment from the lateral femur condyle would increase in size and weight after soaking in normal saline (NS) for 14 days.

Design: Twelve 6-mm OAT (osteoarticular transfer) plugs were harvested from 6 cadaver knees on the lateral femoral condyle to simulate a chondral fragment. The chondral fragments were then placed inside an airtight specimen container with NS (0.9% sodium chloride) and were measured over 14 days.

Results: After 14 days, the chondral fragments showed no increase in diameter as they measured an average of 5.567 ± 0.448 mm on Day 1 and 5.702 ± 0.253 mm on Day 14 (P = 0.183). The chondral fragments showed an increase in mass from an average of 0.058 ± 0.012 g on Day 1 to 0.073 ± 0.012 g on Day 14 (P < 0.001) and an increase in thickness from an average of 2.038 ± 0.346 mm on Day 1 to 2.229 ± 0.297 mm on Day 14 (P = 0.033).

Conclusions: Chondral fragments in NS increase in mass and thickness over time, but do not change in diameter. When surgeons are evaluating loose chondral fragments for fixation, they should consider that these fragments may appear thicker than the recipient location.

在正常盐水中浸泡后股外侧游离软骨碎片肿胀的体外评估。

目的：外伤性膝关节损伤后，软骨碎片可从骨上撕下，其后代碎片形成疏松体。当试图通过手术将碎片修复回原位时，松散的碎片可能比预期的要大。本研究的目的是确定在生理盐水（NS）中浸泡14天后，股骨外侧髁的松散软骨碎片的大小和重量是否会增加。设计：从股骨外侧髁上的6具尸体膝盖上采集12个6mm OAT（骨关节转移）栓塞，以模拟软骨碎片。然后将软骨碎片放入装有NS（0.9%氯化钠）的气密样品容器中，并在14天内进行测量。结果：14天后，球粒碎片的直径没有增加，第1天平均为5.567±0.448 mm，第14天平均为5.702±0.253 mm（P=0.183）。球粒碎片质量从第1天的平均0.058±0.012 g增加到第14天的0.073±0.012克（P<0.001），厚度从第1天平均2.038±0.346 mm增加到第2天的2.229±0.297 mm14（P=0.033）。结论：NS中软骨碎片的质量和厚度随着时间的推移而增加，但直径没有变化。当外科医生评估松动的软骨碎片进行固定时，他们应该考虑到这些碎片可能比受体位置更厚。

期刊介绍： CARTILAGE publishes articles related to the musculoskeletal system with particular attention to cartilage repair, development, function, degeneration, transplantation, and rehabilitation. The journal is a forum for the exchange of ideas for the many types of researchers and clinicians involved in cartilage biology and repair. A primary objective of CARTILAGE is to foster the cross-fertilization of the findings between clinical and basic sciences throughout the various disciplines involved in cartilage repair. The journal publishes full length original manuscripts on all types of cartilage including articular, nasal, auricular, tracheal/bronchial, and intervertebral disc fibrocartilage. Manuscripts on clinical and laboratory research are welcome. Review articles, editorials, and letters are also encouraged. The ICRS envisages CARTILAGE as a forum for the exchange of knowledge among clinicians, scientists, patients, and researchers. The International Cartilage Repair Society (ICRS) is dedicated to promotion, encouragement, and distribution of fundamental and applied research of cartilage in order to permit a better knowledge of function and dysfunction of articular cartilage and its repair.
