Chronic plantar fasciitis is a common but sometimes difficult condition to successfully treat. Platelet rich plasma (PRP), a concentrated bioactive component of autologous blood that is rich in cytokines and other growth factors, was compared with cortisone injection in the treatment of severe cases of plantar fasciitis resistant to traditional non-operative paradigms. Thirty-six patients (16 males 20 females) were prospectively block-randomized into two study groups. All patients had pre-treatment MRI and ultrasound studies consistent with plantar fasciitis. The first group was treated with a single ultrasound guided injection of 40 mg Depo-Medrol at the injury site and the second group was treated with a single ultrasound guided injection of un-buffered autologous PRP at the injury site. The cortisone group had an average age of 59 (24–74) and had failed 4 months (3–24) of standard non-operative management (rest, heel lifts, PT, NSAIDS, cam walker immobilization, night splinting, local modalities) and had pre-treatment AOFAS scores of 52 (24–60). The PRP group had an average age of 51 (21–67) and had failed 5 months (3–26) of standard non-operative management (rest, heel lifts, PT, NSAIDS, cam walker immobilization, night splinting, local modalities) and had pre-treatment AOFAS scores of 37 (30–56). All patients were then immobilized fully weight bearing in a cam walker for 2 weeks, started on eccentric home exercises and then allowed to return to normal activities as tolerated and without support. Post-treatment AOFAS scores in the cortisone initially improved to 81(60–90) at 3 months but decreased to 74 (56–85) at 6 months. Post-treatment AOFAS scores in the PRP group improved to 95 (84–90) at 3 months and remained excellent at 94 (87–100) at 6 months follow-up. This study suggests that platelet rich plasma injection is more effective and durable than cortisone injection for the treatment of severe chronic plantar fasciitis refractory to traditional non-operative management

Lateral Epicondylitis is a common condition caused by angiofibroblastic hyperplasia of the tendinous insertion. Its treatment is varied and includes rest, physiotherapy, corticosteroid injection and surgical release. Of late, the role of Platelet Rich Plasma (PRP) injections have been explored, with positive results. We prospectively assessed the outcomes of lateral epicondylitis treated with PRP injections and compared the outcomes of ultrasound guided and ‘blind’ injection. This was a single centre prospective cohort study. Patient were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) Score. PRP was injected into and around the common extensor origin either with or without ultrasound guidance. The primary outcome measure was DASH score at 3 months. 45 (23F:22M) patients were recruited. The mean age was 50 years (range 35 to 79). The mean duration of follow-up was 106 days. The average pre-injection DASH score for both groups combined was 45.5 (11.7–87.5). The mean DASH score at 3 months follow-up was 27.7. The ultrasound guided injection group had a mean improvement in DASH score from 45.5 to 31.2. The “blind” injection group had a mean improvement in DASH from 44.4 to 27.7. No complications were noted. There was no statistically significant difference in improvement in DASH score between the two groups. Our study provides further evidence to support of the use of PRP injections in the treatment of epicondylitis of the elbow. Interestingly, however, we found that the use of Ultrasound guidance does not appear to improve patient outcomes

We report the outcome of 84 nonunions involving long bones which were treated with rhBMP-7, in 84 patients (60 men: 24 women) with a mean age 46 years (18 to 81) between 2003 and 2011. The patients had undergone a mean of three previous operations (one to 11) for nonunion which had been present for a mean of 17 months (4 months to 20 years). The nonunions involved the lower limb in 71 patients and the remainder involved the upper limb. A total of 30 nonunions were septic. Treatment was considered successful when the nonunion healed without additional procedures. The relationship between successful union and the time to union was investigated and various factors including age and gender, the nature of the nonunion (location, size, type, chronicity, previous procedures, infection, the condition of the soft tissues) and type of index procedure (revision of fixation, type of graft, amount of rhBMP-7) were analysed. The improvement of the patients’ quality of life was estimated using the Short Form (SF) 12 score.

A total of 68 nonunions (80.9%) healed with no need for further procedures at a mean of 5.4 months (3 to 10) post-operatively. Multivariate logistic regression analysis of the factors affecting union suggested that only infection significantly affected the rate of union (p = 0.004).Time to union was only affected by the number of previous failed procedures (p = 0.006). An improvement of 79% and 32.2% in SF-12 physical and mental score, respectively, was noted within the first post-operative year.

Rh-BMP-7 combined with bone grafts, enabled healing of the nonunion and improved quality of life in about 80% of patients. Aseptic nonunions were much more likely to unite than septic ones. The number of previous failed operations significantly delayed the time to union.
