Purpose
This study aimed to investigate the relationship between clinical outcomes, patient demographics and the 3D-geometric profiles of the osteochondral lesion of the talus (OLT) following arthroscopic debridement and bone marrow stimulation.Methods
Between 2005 and 2011, arthroscopic debridement and bone marrow stimulation were performed on 50 ankles with OLT mean age of 36.0 (19.1) years and mean follow-up time of 35.5 (20.2) months. Clinical data were assessed using validated Japanese Society of Surgery of the Foot scoring. An outcome was deemed unsatisfactory if the JSSF score was less than 80. Magnetic resonance imaging and X-rays were used to assess the 3D-geometric profiles of the OLT.Results
The mean preoperative and postoperative scores were 73.4 (13.6) and 89.6 (11.5), respectively (p < 0.001). Unsatisfactory outcomes were identified in 12 % of patients. Linear regression analyses showed that lesion depth and patient age were significantly negatively correlated with postoperative scores (p < 0.001). High prognostic significances were attributed to defect depth and age of patient, and cut-off values of 7.8 mm and 80 years, respectively, were recommended to avoid a postoperative score less than 80. No significant correlations between poor clinical outcome and the other lesion profiles or demographic factors were identified.Conclusion
Using 3D-geometric and demographic profiles, defect depth and age of patient are essential prognostic factors in OLT and may act as a basis for preoperative surgical decisions. A lesion depth ≥7.8 mm and age ≥80 years predict an unsatisfactory outcome following arthroscopic debridement and bone marrow stimulation.Level of evidence

Aqueous solutions of blends of biodegradable triblock copolymers, composed of poly(D,L-lactide-co-glycolide) (PLGA) and poly(ethylene glycol) (PEG) with varied D,L-lactide to glycolide ratios, displayed thermosensitivity and formed a gel at body temperature. The gel window of the blend solutions could be tuned by varying the blending ratio between the two components. Furthermore, the storage modulus of the resultant hydrogel from the copolymer blends at body temperature was higher than that of each individual component. Incorporation of poly(D,L-lactide) (PDLLA) microparticles (0.5-40% w/v) within the in situ gelling hydrogel did not change the sol-gel transition temperatures of the polymer solutions, while the mechanical strength of the resultant hydrogels was enhanced when the content of the microparticles was increased up to 30% and 40%. Incorporation of proteins into both the gel and microparticle components resulted in composites that controlled the kinetics of protein release. Protein within the gel phase was released over a 10-day period whilst protein in the microparticles was released over a period of months. This system can be used to deliver two drugs with differing release kinetics and could be used to orchestrate tissue regeneration responses over differing timescales. 相似文献
