    PROTOCOL FOR TREATING ACUTE INFECTIONS IN CASES OF TOTAL KNEE ARTHROPLASTY
    (2019) PECORA, Jose Ricardo; LIMA, Ana Lucia Munhoz; HELITO, Camilo Partezani; GOBBI, Riccardo Gomes; DEMANGE, Marco Kawamura; CAMANHO, Gilberto Luis
    Objective: To retrospectively evaluate the results after applying a protocol for treating acute infections in cases of total knee arthroplasty and to establish factors predictive of success or failure. Methods: Thirty-two patients who were diagnosed with acute infection of the knee following total arthroplasty between 2004 and 2009 were retrospectively evaluated. Infections following arthroplasty were treated in accordance with the protocol for acute infections following arthroscopy recommended at our institution. Results: With application of a treatment protocol for acute infections following total knee arthroplasty, 26 patients (81.2%) had good results and 6 (18.8%) had unsatisfactory results. Statistical analysis showed that the variables correlated with a worse prognosis were age (p = 0.038) and number of surgical debridement procedures performed (p = 0.038). Conclusion: Our treatment routine was effective for infection. Prosthesis revision was performed in 2 cases when the initial surgical debridement failed to control the infection.

    Clinical results of pulsed signal therapy on patellofemoral syndrome with patellar chondropathy
    (2019) GOBBI, Riccardo Gomes; SILVA, Adriana Lucia Pastore e; DEMANGE, Marco Kawamura; PECORA, Jose Ricardo; ESPREGUEIRA-MENDES, Joao; CAMANHO, Gilberto Luis
    This study was designed to evaluate the effect of pulsed signal therapy (PST) on patellofemoral pain syndrome associated with patellar chondropathy. A prospective randomized double-blind placebo controlled trial included 25 patients (41 knees) between 20 and 50 years with pain due to isolated patellofemoral syndrome with chondropathy. PST group received nine 60-min daily sessions of PST treatment. Control group received the same protocol of blinded placebo treatment. The main outcome was change from baseline Kujala score at 3 months. After 3 months, patients in the control group received effective treatment (placebo post-treatment). All patients were then followed, for up to 12 months. Seventeen knees (5 males and 12 females, mean age 36.7 +/- 7.9) received placebo and 24 knees (8 males and 16 females, mean age 35.5 +/- 8.9) received PST. By the third month, PST group exhibited a mean change from baseline of 9.63 +/- 7.5 Kujala points, compared to 0.53 +/- 1.8 in the placebo group (P < 0.001). A significant progressive improvement was seen in the PST group between the 3rd and 6th and between the 6th and 12th month (P < 0.016). Patients initially allocated in the control group also improved at 3 months (P < 0.001) and 6 months (P = 0.005) post-effective treatment. In conclusion, PST in patellofemoral pain syndrome with chondropathy was effective compared to placebo at 3 months, showing an important improvement of Kujala score. The improvement was progressive and maintained up to 12 months. PST is safe and should be considered as a non-invasive option for management of this condition. Bioelectromagnetics. 40:83-90, 2019.

    The Vastus Medialis Insertion Is More Proximal and Medial in Patients With Patellar Instability: A Magnetic Resonance Imaging Case-Control Study
    (2019) GOBBI, Riccardo Gomes; HINCKEL, Betina Bremer; TEIXEIRA, Paulo Renan Lima; GIGLIO, Pedro Nogueira; LUCARINI, Bruno Romano; PECORA, Jose Ricardo; CAMANHO, Gilberto Luis; DEMANGE, Marco Kawamura
    Background: The anatomy and function of the quadriceps muscle play a role in patellofemoral stability. Few studies have evaluated anatomic differences in the vastus medialis between patients with and without patellar instability. Purpose: To compare the anatomy of the vastus medialis using magnetic resonance imaging in patients with patellar instability to a control group. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A group of patients with patellar instability were sex-matched with a control group with anterior cruciate ligament tears, meniscal injuries, or sprains; patients younger than 15 years were excluded. The anatomy of the vastus medialis was examined by the distance between the distal origin of the vastus medialis in the femur and the medial femoral condyle, the distance from the proximal pole of the patella to the most distal insertion of the muscle and its ratio to the length of the articular surface of the patella, and a qualitative description of the insertion position of the muscle fibers (directly in the patella or the medial retinaculum). Results: Both groups comprised 78 knees (48 female; 61.5%). The mean age in the control and patellar instability groups was 30.2 +/- 7.8 years and 25.6 +/- 7.5 years, respectively (P = .001). The distance from the vastus origin to the condyle was 27.52 +/- 3.49 mm and 26.59 +/- 3.43 mm, respectively (P = .041); the distance from the proximal pole of the patella to the most distal muscle insertion was 17.59 +/- 5.54 mm and 15.02 +/- 4.18 mm, respectively (P < .001); and the ratio of this distance to the joint surface was 0.586 +/- 0.180 and 0.481 +/- 0.130, respectively (P < .001). In 75.6% of knees in the patellar instability group, the insertion of the vastus was into the medial retinaculum and not into the patella compared with 52.6% in the control group (P = .003; odds ratio, 2.8). Conclusion: The distal insertion of the vastus medialis differed in knees with patellar instability, with a more proximal insertion and less patellar coverage relative to controls, and was more frequently found in the retinaculum instead of directly in the patella.
