  • EFFECT OF WEIGHT-BEARING TIME ON MICRO-FRACTURE THERAPY FOR SMALL SIZED OSTEOCHONDRAL LESION OF TALUS

    Objective To evaluate the effect of weight-bearing time on micro-fracture therapy for small sized osteochondral lesion of the talus (OLT) by comparing early weight-bearing and postponed weight-bearing. Methods Between March 2010 and September 2011, 43 patients with small sized OLT (lt; 2 cm2) scheduled for arthroscopic micro-fracture therapy were randomly divided into early weight-bearing group (n=22) and postponed weight-bearing group (n=21). There was no significant difference in gender, age, body mass index, disease duration, disease cause, preoperative visual analogue scale (VAS) score, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score between 2 groups (P gt; 0.05). All patients of 2 groups received micro-fracture treatment under arthroscopy. Full weight bearing began under the protection of “8” figure shaped splint at immediately after operation in early weight-bearing group, and weight bearing began at 6 weeks after operation in postponed weight-bearing group. Results The size of cartilage injury was (1.24 ± 0.35) cm2 in early weight-bearing group and was (1.25 ± 0.42) cm2 in postponed weight-bearing group by arthroscopy measurement, showing no significant difference between 2 groups (t=0.09, P=0.93); and there was no significant difference in cartilage injury grading between 2 groups (Z= — 1.45, P=0.15). The follow-up time was 12-18 months (mean, 14.5 months) in 2 groups. VAS and AOFAS scores of each group at each time point after operation were all significantly improved when compared with preoperative scores (P lt; 0.05), but no significant difference was found between 2 groups at 3, 6, and 12 months after operation (P gt; 0.05). The time of returning to work in early weight-bearing group [(6.35 ± 1.93) months] was significantly shorter than that in postponed weight-bearing group [(8.75 ± 1.48) months] (t= — 4.10, P=0.00). Conclusion For patients with small sized OLT, early weight-bearing and postponed weight-bearing after micro-fracture therapy under arthroscopy have similar short-term results. But patients undergoing early weight-bearing can earlier return to work than patients undergoing postponed weight-bearing.

  • Micro-fracture therapy combined with intra-articular injection of platelet-rich plasma for small sized osteochondral lesion of the talus

    ObjectiveTo investigate the effectiveness of micro-fracture therapy combined with intra-articular injection of platelet-rich plasma (PRP) in the treatment of small sized osteochondral lesion of the talus (OLT).MethodsBetween September 2014 and October 2017, 43 patients with small sized OLT met the inclusive criteria were admitted and randomly divided into micro-fracture group (21 cases) and combined group (22 cases). Patients in the micro-fracture group were treated with micro-fracture therapy, and patients in the combined group were treated with micro-fracture therapy combined with intra-articular injection of PRP. There was no significant difference in gender, age, disease duration, side of OLT, injured position, lesion area, Mintz classification, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score and visual analogue scale (VAS) score between the two groups (P>0.05). After treatment, MRI, VAS score, and AOFAS ankle-hind foot score were used to evaluate the recovery of OLT and the ankle function.ResultsAll incisions healed by first intention, and no complications such as venous thrombosis and ankle joint infection occurred. All patients were followed up 12-18 months after operation, with an average of 15.6 months. The VAS scores and the AOFAS ankle-hind foot scores were significantly improved at 6 and 12 months after operation in the two groups (P<0.05), and the scores at 12 months were significantly improved when compared with postoperative scores at 6 months (P<0.05). Compared with the micro-fracture group, the VAS score and the AOFAS ankle-hind foot score were significantly improved in the combined group at 6 and 12 months after operation (P<0.05). MRI showed that OLT was well filled in both groups at 12 months after operation.ConclusionCompared with micro- fracture therapy, micro-fracture therapy combined with intra-articular injection of PRP can effectively reduce pain, improve ankle function, and has a good effectiveness in the treatment of small sized OLT.
