The use of PRP does not seem to be effective in preventing tunnel enlargement.
Minimally invasive surgery has become a trend over the last few years in all aspects of orthopaedic surgery, including total hip arthroplasty. So-called mini-incision techniques involve limiting the length of the skin incision to 10 cm with use of either an anterior, lateral or posterior approach. Between March 2004 and December 2005 one hundred consecutive unilateral total hip replacements were performed by the same senior surgeon in our institute. All patients were randomly assigned to study group (group A) or control group (group B). In group A (50 patients) the skin incision was 8 cm; in group B (50 patients) the skin incision was standard (about 12-14 cm). Patient demographic data, including sex, age, height, weight, BMI, diagnosis and preoperative Harris hip score were recorded. Other criteria evaluated included the perioperative and postoperative complications, the surgical time, the blood loss, the length of the incision, the acetabular and stem positions, the length of hospital stay, Harris Hip Score (HHS) and the WOMAC osteoarthritis index at six months. No significant differences were found between the groups with respect to the average surgical time, the acetabular and stem position, the length of hospital stay and the Harris Hip Score (HHS) and the WOMAC osteoarthritis index at six months. A significant lower blood loss was found in the mini-incision group. A higher percentage of peri-operative complications was recorded in Group A (two stupor of sciatic nerve and one fracture of the greater trochanter). On the basis of our experience we could speculate that minimally invasive surgery should be directed to the new surgical approach with muscle sparing, instead of a shorter skin incision using standard approaches.
BackgroundAmong the various complications described in literature, the patellar tendon ossification is an uncommon occurrence in anterior cruciate ligament (ACL) reconstruction using bone – patellar tendon – bone graft (BPTB). The heterotopic ossification is linked to knee traumatism, intramedullary nailing of the tibia and after partial patellectomy, but only two cases of this event linked to ACL surgery have been reported in literature.Case presentationWe present a case of a 42-year-old Caucasian man affected by symptomatic extended heterotopic ossification of patellar tendon after 20 months from ACL reconstruction using BPTB. The clinical diagnosis was confirmed by Ultrasound, X-Ray and Computed Tomography studies, blood tests were performed to exclude metabolic diseases then the surgical removal of the lesion was performed. After three years from surgery, the patient did not report femoro-patellar pain, there was not range of motion limitation and the clinical-radiological examinations resulted negative.ConclusionThe surgical removal of the ossifications followed by anti-inflammatory therapy, seems to be useful in order to relieve pain and to prevent relapses. Moreover, a thorough cleaning of the patellar tendon may reveal useful, in order to prevent bone fragments remain inside it and to reduce patellar tendon heterotopic ossification risk.

Tenosynovial giant cell tumors originate from the synovial tissue of the joints, tendon sheaths, mucosal bursas, and fibrous tissues adjacent to tendons. The disease presents in localized and diffused forms. Large joints, such as the knee, are not frequently affected. Magnetic resonance imaging has been reported to be the best noninvasive technique to diagnose these tumors. Magnetic resonance imaging diagnosis has to be confirmed by histopathological examination. Few reports exist of tenosynovial giant cell tumors arising from the posterior cruciate ligament. This article describes a case of an 18-year-old man with no history of trauma but with a 2-year history of mild, ongoing, and worsening right knee pain and swelling localized in the popliteal region. Clinical examination of the knee was negative. Magnetic resonance imaging revealed an intra-articular mass measuring 4.8×2.1×2.7 cm in the posterior region of the knee attached to the posterior cruciate ligament. Arthroscopy was performed using the posterior approach through the posterolateral and posteromedial portals. A specimen of the lesion was removed arthroscopically for histopathological examination, and a wide resection of the mass was performed with a shaver and a radiofrequency ablation device. Histopathological examination confirmed the diagnosis of a tenosynovial giant cell tumor. No recurrence had occurred at 2-year follow-up. Magnetic resonance imaging and histopathological examination may help in achieving a correct diagnosis, and arthroscopic excision using a posterior approach may be the treatment of choice by surgeons.
