Treatment of plantar fasciitis using four different local injection modalities: a randomized prospective clinical trial.

BACKGROUND To determine the effectiveness of four different local injection modalities in the treatment of plantar fasciitis. METHODS In a prospective randomized multicenter study of plantar fasciitis, 100 patients were divided into four equal groups and were treated using four different methods of local injection: group A was treated with 2 mL of autologous blood alone; group B, an anesthetic (2 mL of lidocaine) combined with peppering; group C, a corticosteroid (2 mL of triamcinolone) alone; and group D, a corticosteroid (2 mL of triamcinolone) combined with peppering. The outcome was defined by using a 10-cm visual analog scale and modified criteria of the Roles and Maudsley score 3 weeks and 6 months after the injection and compared with the pretreatment condition. RESULTS The successful results in all of the groups after injections were higher than those in the pretreatment condition (P = .000). In groups C and D, in which local corticosteroid injections were used, excellent results were obtained, with superior effect in the group in which peppering was used (P < .05). CONCLUSIONS In the treatment of plantar fasciitis, combined corticosteroid injections and peppering is effective and produces better clinical results.

Autologous Blood and Corticosteroid Injection and Extracoporeal Shock Wave Therapy in the Treatment of Lateral Epicondylitis

Lateral epicondylitis is a common disorder characterized by pain and tenderness over the lateral epicondyle. It occurs most frequently as a result of minor, unrecognized trauma during sports activities and occupation-related physical activities. The goal of this study was to evaluate the short-, medium-, and long-term effects of corticosteroid injection, autologous blood injection, and extracorporeal shock wave therapy in the treatment of lateral epicondylitis.Sixty patients (32 women, 28 men) with lateral epicondylitis were randomly divided into 3 groups: group 1 received a corticosteroid injection; group 2, an autologous blood injection, and group 3, extracorporeal shock wave therapy. Thomsen provocative testing, upper extremity functional scores, and maximal grip strength were used for evaluation. Outcomes were assessed at 4, 12, 26, and 52 weeks. Corticosteroid injection gave significantly better results for all outcome measures at 4 weeks; success rates in the 3 groups were 90%, 16.6%, and 42.1%, respectively. Autologous blood injection and extracorporeal shock wave therapy gave significantly better Thomsen provocative test results and upper extremity functional scores at 52 weeks; the success rate of corticosteroid injection was 50%, which was significantly lower than the success rates for autologous blood injection (83.3%) and extracorporeal shock wave therapy (89.9%). Corticosteroid injection provided a high success rate in the short term. However, autologous blood injection and extracorporeal shock wave therapy gave better long-term results, especially considering the high recurrence rate with corticosteroid injection. We suggest that the treatment of choice for lateral epicondylitis be autologous blood injection.

Effect of strontium ranelate on fracture healing in the osteoporotic rats

The aim of this study was to evaluate the effect of strontium ranelate (SrR) on fracture healing in the osteoporotic rat model. Forty female Sprague–Dawley rats aged 3 months were enrolled in the study. Osteoporosis was induced by bilateral ovariectomy and subsequent daily heparin injection started 1 week after surgery and lasted for 4 weeks. Osteoporosis was confirmed by a reduction of bone mineral density (BMD). Twenty of the osteoporotic rats were assigned to the SrR group and the remaining 20 to the control group. An open right tibial midshaft transverse fracture was created and then an intramedullary fixation was performed. SrR group was treated by 450 mg/kg/day SrR per oral. Six weeks after surgical induction of fracture, all animals were sacrificed. One animal from each group died after ovariectomy. Two tibiae from the control group failed to unite. SrR‐treated group showed higher mechanical strength and fracture stiffness when compared to the control group (p = 0.006, p = 0.001, respectively). SrR‐treated group had mature woven bone or predominantly woven bone compared with osteoporotic control group (p = 0.038). SrR‐treated groups callus maturity was significantly higher than control group (p = 0.001). SrR is associated with better fracture healing in the osteoporotic rat model.

Effect of platelet-rich plasma on tendon-to-bone healing after rotator cuff repair in rats: an in vivo experimental study

OBJECTIVE The purpose of this experimental study was to analyze the effects of local autologous platelet-rich plasma (PRP) injection on tendon-to-bone healing in a rotator cuff repair model in rats. METHODS Rotator cuff injury was created in 68 left shoulders of rats. PRP was obtained from the blood of an additional 15 rats. The 68 rats were divided into 4 groups with 17 rats in each group; PRP group (Week 2), control group (Week 2), PRP group (Week 4), and control group (Week 4). Platelet-rich plasma or saline was injected to the repair area intraoperatively. Rats were sacrificed 2 and 4 weeks after the surgery. Histological analysis using a semiquantitative scoring was performed on 7 rats per group. Tendon integrity and increases in vascularity and inflammatory cells and the degree of new bone formation were evaluated and compared between the groups. The remaining tendons (n=10) were mechanically tested. RESULTS Degree of inflammation and vascularity were less in the study group at both time intervals (p<0.05). Tendon continuity was better in the study group at 2 weeks (p<0.05). Obvious new bone formation was detected in the control group at 4 weeks (p<0.05). Biomechanically, platelet-rich plasma-treated specimens were stronger at 2 weeks (p<0.05). CONCLUSION Local autologous PRP injection may have beneficial effects on initial rotator cuff tendon-to-bone healing and enhance initial tendon-to-bone healing remodeling. This may represent a clinically important improvement in rotator cuff repair.

Does platelet-rich plasma enhance microfracture treatment for chronic focal chondral defects? An in-vivo study performed in a rat model

OBJECTIVE The purpose of the present study was to compare the effectiveness of platelet-rich plasma (PRP) + microfracture and microfracture treatments in the healing of chronic focal chondral defects. METHODS The study included 57 adult male Sprague-Dawley rats. Forty-two rats were divided into three groups of 14 rats with a chondral defect (control, microfracture only, PRP+microfracture). The remaining 15 rats were used to produce the PRP preparation. The rats were then euthanatized at 3 and 6 weeks after treatment and examined. Histological analysis using the modified Pineda scoring system and immunohistochemical staining for Type 2 collagen were performed. RESULTS At both time intervals, control group histological scores (Week 3: 8.8±1.2, Week 6: 8.5±0.7) were higher than microfracture (Week 3: 6.8±1.0, Week 6: 7.1±0.6) and PRP+microfracture (Week 3: 6.4±1.3, Week 6: 5.7±1.2) scores (p<0.05). The microfracture group score was higher at Week 6 than the PRP+microfracture group (p<0.05). The degree of Type 2 collagen staining was higher at Week 6 in the PRP+microfracture group and was unique in showing staining at the cell membrane. CONCLUSION The addition of PRP application to microfracture treatment appears to enhance cartilage healing in chronic focal chondral defects.

A new radiographic measurement method for evaluation of tibial torsion: a pilot study in adults.

Computed tomography (CT) frequently is used to determine torsional abnormalities. However, its use in clinical practice may be limited. We present a new method for measuring tibial torsion using conventional radiographs. We compared the method with several clinical methods and with CT measurement in 44 lower extremities of 25 subjects. The radiographic method agreed well with all of the clinical methods, and this agreement was better than agreement between CT and clinical examination. The best agreement was between thigh-foot angle and the radiographic method. The proposed radiographic measurement is a practical method for evaluation of tibial torsion in outpatient clinics without the need for specialized equipment.Level of Evidence: Level II, diagnostic study.

Lipoma Arborescens of the Suprapatellar Bursa and Extensor Digitorum Longus Tendon Sheath Report of 2 Cases

Lipoma arborescens (diffuse articular lipomatosis) is a rare intra‐articular lesion consisting of subsynovial villous proliferation of mature fat cells. The usual clinical presentation is painless swelling. The aim of this series was to emphasize the importance of gray scale and color Doppler sonography through the investigation of chronic joint swelling.

Patellar tendinopathy caused by a para-articular/extraskeletal osteochondroma in the lateral infrapatellar region of the knee: a case report

Patellar tendinopathy is characterized by activity-related anterior knee pain. It is most commonly related to sports activity, but has also been reported in the non-athletic population. Most injuries are caused by microtrauma, resulting in tendinitis or tendinosis. Extraskeletal paraarticular osteochondromas, which occur in the soft tissues near the joint, are rare. The infrapatellar fat pad and joint capsule are the most common sites of these tumors. Here, a case of patellar tendinitis caused by an extraskeletal paraarticular osteochondroma is reported. The symptoms included intensifying pain upon flexion and a palpable click that was located at the medial side of the mass. The patient was pain-free within 3 weeks after excision of the tumor and the clicking disappeared. To our best knowledge, no other case of patellar tendinitis caused by an extraskeletal paraarticular osteochondroma has been reported in the English literature.

Efficacy of moxifloxacin compared to teicoplanin in the treatment of implant‐related chronic osteomyelitis in rats

Treatment of implant‐related chronic osteomyelitis is often difficult and usually consists of implant removal, extensive surgical debridement, and prolonged antibiotic use. This study was performed to assess the efficacy of moxifloxacin compared to a glycopeptide, teicoplanin in chronic implant‐related methicillin‐sensitive Staphylococcus aureus (MSSA) osteomyelitis. The left femoral medullar cavities of 60 Wistar male rats were contaminated with 100 µl of 108 cfu/ml methicillin‐sensitive S. aureus (ATCC 29213) and Kirschner wires were placed into the medulla of the femur. After 6 weeks, rats were randomly divided into five groups. In two groups, the Kirschner wires were removed. Experimental groups were as follows: group 1: contaminated, Kirschner wire inside, received teicoplanin; group 2: contaminated, Kirschner wire removed, received teicoplanin; group 3: contaminated, Kirschner wire inside, received moxifloxacin; group 4: contaminated, Kirschner wire removed, received moxifloxacin; group 5: contaminated, Kirschner wire inside, no antibiotics (control group). Groups 1 and 2 received teicoplanin (20 mg/kg once daily), whereas groups 3 and 4 received moxifloxacin (10 mg/kg twice daily) intraperitoneally for 28 days. At the end of the treatment, animals were sacrificed by inhalation anesthesia with ether and femora were retrieved and bacterial counts (cfu/g) were determined. Bacterial counts in all study groups were significantly reduced relative to the control. The decrease of bacterial counts was more prominent in group 4 compared to group 1 (p = 0.001) and group 2 (p = 0.003). Moxifloxacin therapy is an effective alternative to teicoplanin for chronic implant‐related MSSA osteomyelitis. Published by Wiley Periodicals, Inc. J Orthop Res 28:1368–1372, 2010

Patellar tendon ossification after partial patellectomy: a case report

IntroductionPatellar tendon ossification is a rare pathology that may be seen as a complication after sleeve fractures of the tibial tuberosity, total patellectomy during arthroplasty, intramedullary nailing of tibial fractures, anterior cruciate ligament reconstruction with patellar tendon autograft and knee injury without fracture. However, its occurrence after partial patellectomy surgery has never been reported in the literature.Case presentationWe present the case of a 35-year-old Turkish man with a comminuted inferior patellar pole fracture that was treated with partial patellectomy. During the follow-up period, his patellar tendon healed with ossification and then ruptured from the inferior attachment to the tibial tubercle. The ossification was excised and the tendon was subsequently repaired.ConclusionTo the best of our knowledge, this is the first report of patellar tendon ossification occurring after partial patellectomy. Orthopaedic surgeons are thus cautioned to be conscious of this rare complication after partial patellectomy.
