A complication following ACL reconstruction using bioabsorbable cross-pins
This is a case of a proximal pin migration after ACL reconstruction in medial soft tissue with pain, inflammatory reaction and functional reduction. 33-year-old male presented at our clinic with a complete ACL rupture. Reconstruction with autogenous gracilis and semitendinosus hamstring tendons was performed and graft fixed in the femoral canal with two PLLA bioabsorbable pins (RIGIDFIX\uae Cross Pin System). Two months postoperatively the patient presented swelling and pain on the medial side of the knee, full range of motion and negative results at the Lachman and Pivot shift tests. MRI examination showed the superior femoral tunnel crossing both the lateral and medial cortex lodging the pin in the knee\u2019s medial soft tissue corresponding to the swelling area reported by the patient. The tendon graft was properly positioned. After surgical removal of the pin through a small skin incision, the pain and swelling promptly subsided allowing the patient return to normal activities in few weeks without any pain. In our opinion the painful swelling of the knee was due to a displacement of the pin that had been accidentally lodged in the soft tissues instead of the bone causing a foreign-body reaction resulting in granuloma formation with local inflammation. This dislodgement could have been due to an inappropriately long femoral tunnel
Use of a non-medicated plaster in shoulder tendinopathies
We assessed 20 shoulders with rotator cuff tendinopathy and partial tendon tears treated with FIT\uae plasters (far infrared technology). The criteria for inclusion were pain at night and during active shoulder movement. Patients with restricted passive movement (adhesive capsulitis) and complete tendon tears were excluded. Two different types of FIT\uae plasters were used according to the different power of action. Plasters were replaced after 7 days and dismissed after 15 days. The patients were assessed using the VAS pain scale and the Constant Murley score for function. The use of FIT\uae plasters have shown a certain effectiveness in activation of the endogenous analgesic action, with a role in alleviate painful symptoms and improve function in rotator cuff tendinopathies, without adverse events. On the base of the safety of this technology and promising results of our study, further studies should be encouraged to confirm its effectiveness, increasing the sample number and follow up so as to demonstrate definitely that the use of technologies, on which FIT\uae plasters is based, may be a valid alternative as "non-medicated pain relief"

Antibiotic-Loaded Spacer for Two-Stage Revision of Infected Total Knee Arthroplasty
Background\u2003Infection of total knee arthroplasty (TKA) is a challenge in orthopedic surgery. In literature TKA infection is classified according to the time after surgery: acute postoperative; late chronic; acute hematogenous; positive intraoperative microbiological growth. Purpose\u2003The purpose of this study is to present the results of the use of a preformed antibiotic-loaded spacer in TKA infections, treated by a two-stage revision procedure. Patients and Methods\u2003A series of 19 consecutive patients (20 knees) with a diagnosis of infected TKA were treated from January 2003 to February 2012. Two-stage reimplantation protocols were completed only in 16 patients and these data were included in the study. We lost three patients at follow-up. An antibiotic-loaded preformed articulating polymethylmethacrylate spacer was applied. Patients were observed 1, 3, and 6 months postoperatively and then yearly for clinical and radiographic examination. Results\u2003The mean American Knee Society Score improved from 68.4 preoperatively (range, from 34 to 108) to 112.7 at final follow-up (range, from 49 to 180). The pain was evaluated as part of clinical score. It improved from an average of 19.3 preoperatively (range, from 10 to 30) to 34.3 at final follow-up (range, from 10 to 50). The average range of motion improved from 40.1 degrees (range, from 6 to 90 degrees) to 79.3 degrees (range, from 45 to 125 degrees). Conclusions\u2003The use of the spacer allows obtaining a reduction of pain, an improvement of quality of life in the period of time between the two surgical stages and an easier reimplantation of TKA
