RESUMO
The present study aimed to determine the outcomes and quality of life after platelet-rich plasma therapy in patients with chronic recalcitrant diseases of the hindfoot and ankle and to identify the crucial clinical variables. The records of 12 adult patients with diseases of the hindfoot and ankle were included in the present study. These patients had been treated with platelet-rich plasma from September 2010 to April 2011 after 3 to 6 months or more of conservative treatment had been unsuccessful. They had attended the follow-up visits, were consecutively enrolled, and retrospectively studied. A total of 3 mL of autologous platelet-rich plasma was injected under fluoroscopic or ultrasound guidance into the affected areas. All patients had been evaluated using visual analog scale foot and ankle scoring before treatment and at set intervals after treatment. According to their scores at the final follow-up visit (mean 16 months), the patients were allocated to the satisfactory (score ≥ 80; n = 8) and unsatisfactory (score < 80; n = 4) groups. The health-related quality of life was assessed using the Medical Outcomes Study short-form, 36-item survey at the final follow-up visit, because the study was retrospective, and the information was not available before treatment. The mean visual analog score at the final follow-up visit (79.71 ± 17.81) was significantly greater than the mean pretreatment score (57.89 ± 20.77; p = .002). Four patients (33%) had unsatisfactory results. The mean short-form, 36-item score for the satisfactory group (85.23 ± 11.30) was significantly greater than that (57.33 ± 12.91) of the unsatisfactory group (p = .003). No definitive factors influencing the outcome of this treatment were found. The substantial number of patients with an unsatisfactory outcome indicates that platelet-rich plasma injection might be an option but might not be a mainstay of nonoperative treatment of problematic conditions of the hindfoot and ankle. The actual benefit of this treatment, including the factors influencing its outcome, are still inconclusive.

BACKGROUND: There are few records for total ankle replacement (TAR) in Asia. We aimed to report the cumulative intermediate-term outcomes in terms of clinical scores, survivorship and failure rates for patients managed with TAR in Asia. METHODS: We conducted a systematic search for relevant articles published in English and other languages between January 1990 and February 2012. The study published before 1990 and used outdated prosthesis designs implanted before the early 1980s was excluded. Eligible studies were evaluated using the Coleman Methodology Score and data collection was independently performed by three reviewers. RESULTS: Seven studies qualified for analysis, describing 321 implants (112 HINTEGRA(®), 104 TNK, 35 STAR, 13 ND-Bioceram, 57 un-reported implants). Overall studies showed the improvement of clinical scores following TAR. Pooled data for the survivorship analysis ranged from 100% at 3.2 years to 77% at 14.1 years. Pooled mean failure rate was 4.9±3.2% over a mean follow-up of 5.2±1.7 years. CONCLUSIONS: TAR prostheses currently used in Asia achieved satisfactory intermediate-term outcomes in terms of clinical scores, survivorship and failure rates.

OBJECTIVE: Several authors have reported the benefits of the recent procedure of the dual portal endoscopic plantar fasciotomy (EPF). However, very little is known concerning its potential capability via the single portal EPF without special cutting device. The present study aimed to demonstrate the effectiveness of uniportal EPF in a patient with severe intractable plantar fasciitis following a failure of several conservative treatments. The recent technique; uniportal EPF under modified method, without a special cutting device, was reviewed in an effort to improve its capability for plantar release and to provide information for the avoidance of this procedure's complications. CASE REPORT: A patient, with the recalcitrant conditions and the progression of the severe plantar fasciitis of bilateral feet after a failure of the conservative treatments for 13-month period, was included in this report. All data of the preoperative and each successive postoperative period (1, 6 months and last follow-up) were prospectively collected including American Orthopedic Foot and Ankle Society (AOFAS) score, Visual Analogue Scale-Foot and Ankle (VAS-FA) score and any related complications. The operations were carried out by a single surgeon with the modified uniportal EPF via a simple hooked soft-tissue blade, without a special cutting device, on both feet simultaneously. All feet had uniportal EPF with transection of the medial 50% of the plantar fascia. Postoperatively, a patient was instructed to have partial-weight bearing for the first 2 weeks with wearing of full-length silicone insoles. Then, she is allowed to start to fully weightbear with the insoles. She is advised to cautiously return to daily activities and works at 2nd week after the operation. In regard to the EPF in two feet, there were clearly improvements in the comparison between preoperative and last follow-up period in terms of the increasing AOFAS scores, and VAS-FA scores. There were no significant iatrogenic-related complications including the lateral column pain in the present report. CONCLUSION: The recalcitrant condition of severe plantar fasciitis is not uncommon for several orthopedic surgeons. Regarding the emerging of several minimally invasive procedures for this condition, our modified uniportal EPF with a simple device was encouraging as a treatment option in releasing the plantar fascia with satisfactory effectiveness and lower risks of complications.

BACKGROUND: Little is known about differences in amounts of antioxidants or oxidative stress at different stages of knee osteoarthritis. This study investigated the relationship between concentrations of antioxidants, iron and lipid peroxidation in synovial fluid and levels of severity of primary knee osteoarthritis. MATERIALS AND METHODS: From 2011 to 2013, 23 patients (mean age, 66.7 ± 7.6 years) with primary knee osteoarthritis were recruited. Patients were divided into 2 groups based on pre-treatment knee society scores (KSS): n = 9, severe KSS ≤46; and n = 14, mild-moderate KSS >46. Synovial fluid was analyzed to determine levels of antioxidants, iron concentrations and lipid peroxidation (thiobarbituric acid reactive substances [TBARs]). Baseline data, including Kellgren- Lawrence radiographic grade, were collected for all patients. RESULTS: Mean KSS was 49.1 ± 10.8. Total mean concentrations of antioxidants were 2.29 ± 1.71 ng/mL vitamin E and 0.47 ± 0.51 nmol/mL glutathione (GSH). Total mean levels of TBARs and iron were 1.20 ± 0.37 nmol/mL and 2.13 ± 0.82 µg/mL, respectively. The mean concentration of vitamin E was inversely related to severity of knee osteoarthritis (mild-moderate > severe, p = 0.006). There were no significant differences between the two groups in terms of GSH (p = 0.90), TBARs (p = 0.84) or iron levels (p = 0.27). There was a significant positive correlation between KSS and vitamin E concentration (r = 0.43, p = 0.04). No significant correlations were shown between KSS and GSH (r = -0.01, p = 0.97), TBARs (r = -0.06, p = 0.81) or iron level (r = 0.28, p = 0.20). CONCLUSION: Using synovial fluid profiles, vitamin E concentration is an essential prognostic factor in primary knee osteoarthritis and may act as a basis for treatment directions. The concentration of vitamin E decreased as the clinical severity of primary knee osteoarthritis increased.
