The majority of patients return to athletic activity following biceps tenodesis.

PURPOSE: Biceps tenodesis is widely used as a primary treatment for long head of the biceps brachii pathology and superior labral anterior and posterior (SLAP) lesions. However, rates and timing of full return to sports (RTSs)/duty have not been systematically analysed. This systematic review examines the literature to ascertain the rate and timing of return to athletic activity, and the availability of specific criteria for safe return to atheletic activity following the biceps tenodesis. METHODS: Based on PRISMA guidelines, this systematic review utilised the EMBASE, MEDLINE, and The Cochrane Library Databases. Eligible for inclusion were clinical studies reporting on return to athletic activity following biceps tenodesis. Statistical analysis was performed using SPSS. RESULTS: This review identified 17 studies including 374 cases meeting the inclusion criteria. The majority of patients were men 260 (69.7%), with an median age of 42.2 years (range 16-88) and a mean follow-up of 37.4 months. The overall rate of RTS was 217/269 (80.7%), with 43/59 (72.9%) returning to the same level. In overhead athletes, the overall rate of return to play was 39/49 (79.6%). Among military personnel, the overall rate of return to duty was 61/74 (82.4%). The average time to RTS was 5.4 (range 3-11) months. 10 (58.8%) Studies reported a recommended time window within which patients were allowed to return to full activity. Specific criteria for return to play were not reported in any of the identified studies. CONCLUSION: While overall rate of return to athletic activity was reportedly high following biceps tenodesis, one in four patients were not able to resume athletic activity at the same level. At present, there is no objective assessment of when patients can return to full activity reported in the literature. LEVEL OF EVIDENCE: IV.

[Pyoderma gangraenosum after implantation of a shoulder endoprothesis]. / Pyoderma gangraenosum nach Implantation einer Schulterendoprothese.

Pyoderma gangrenosum is an inflammatory, ulcerative, neutrophilic dermatosis that is clinically characterized by rapidly evolving, painful, necrotic skin lesions. It is typically associated with chronic systemic inflammatory or neoplastic diseases, but may also occur secondary to cutaneous injury or surgery (pathergy). Post-surgical pyoderma gangrenosum typically develops around surgical sites within the immediate postoperative period, mimicking early wound infection. However, common treatment strategies including antibiotics and debridement fail to improve or even worsen symptoms. Postoperative pyoderma gangrenosum has been most commonly reported from breast and visceral surgery. We present a case of postoperative pyoderma gangrenosum following total shoulder arthroplasty.

[The MyKnee® patient-specific system. Rationale, Technique and Results]. / Das Patientenspezifische MyKnee®-Instrumentarium. Hintergründe, Technik und Ergebnisse.

BACKGROUND: Adequate three-dimensional component positioning and restoration of overall limb alignment are primary goals in total knee arthroplasty. Patient-specific instrumentation (PSI) is a potential way to improve accuracy of knee reconstruction surgery. However, currently available literature regarding the reliability of PSI shows inconsistent results for limb alignment restoration and component positioning. OBJECTIVES: The purpose of this article is to illustrate the rationale for using PSI in total knee arthroplasty, to demonstrate the surgical technique, and to present our outcome with the MyKnee(®) system. METHODS: We illustrate in detail the logistics and workflow involved in PSI for total knee arthroplasty. Finally, we present clinical and radiological results of patients undergoing knee arthroplasty using the MyKnee(®) system compared to a conventional instrumentation group. RESULTS: PSI significantly improved accuracy and reduced the number of outliers regarding neutral mechanical alignment restoration as well as three-dimensional component positioning compared to conventional instrumentation. The early clinical outcome was comparable between the two instrumentation groups. However, clinical outcome in the subgroup of patients within ± 3° from neutral mechanical limb alignment was superior to limb alignment outliers. CONCLUSION: The MyKnee(®) PSI system presents a reliable way to improve the accuracy of mechanical limb alignment restoration and three-dimensional component positioning in total knee arthroplasty. Nonetheless, an adequate surgical technique remains the crucial factor for successful total knee reconstruction.

Bilateral Scapulothoracic Fusions Fixed with High-Strength Suture Tapes for Facioscapulohumeral Dystrophy: A Case Report.

CASE: A 32-year-old male right-hand dominant school-bus driver with facioscapulohumeral dystrophy (FSHD) was referred to an upper limb specialist for consideration for scapulothoracic fusion (STF) because of limited upper limb function and cosmetic issues. Staged bilateral STFs were performed with seven high-strength suture tapes tensioned to secure a standard tubular plate in situ. CONCLUSION: STF may be a desirable treatment option for patients with FSHD. The use of high-strength suture tapes in cases of STF allows for secure fixation of the scapulothoracic joint. This potentially confers a reduction in operative time while ensuring adequate tensioned fixation and minimizing the risk of iatrogenic pneumothorax.

The effect of intravenous tranexamic acid on blood loss and early post-operative pain in total shoulder arthroplasty.

AIMS: The purpose of the present study was to evaluate the impact of intravenous tranexamic acid on the reduction of blood loss, transfusion rate, and early post-operative clinical outcome in total shoulder arthroplasty. PATIENTS AND METHODS: A randomised, placebo-controlled trial which included 54 patients undergoing unilateral primary stemless anatomical or stemmed reverse total shoulder arthroplasty was undertaken. Patients received either 100 ml saline (placebo, n = 27), or 100 ml saline together with 1000 mg of tranexamic acid (TXA, n = 27) intravenously prior to skin incision and during wound closure. Peri-operative blood loss via an intra-articular drain was recorded and total blood loss was calculated. The post-operative transfusion rate was documented. Assessment of early clinical parameters included the visual analogue scale for pain (VAS), documentation of haematoma formation and adverse events. RESULTS: Mean peri-operative blood drainage (placebo: 170 ml versus TXA: 50 ml, p = 0.001) and calculated mean total blood loss (placebo: 1248.2 ml versus TXA: 871.0 ml, p = 0.009) were significantly lower in the TXA group. No transfusions were necessary during the study period in either group. Mean VAS for pain significantly decreased from pre-operative (VAS 7) to the early post-operative period (VAS 1.7, p < 0.001). Significant differences regarding mean post-operative pain between placebo (VAS 2.0) and TXA (VAS 1.3) were detected (p = 0.05). The occurrence of haematomas was significantly more frequent in the placebo (59.3%, n = 16) than in the TXA group (25.9%, n = 6, p = 0.027). Whereas only mild haematomas developed in the TXA group, in the placebo group a total of 22.2% (n = 6) developed either moderate or severe haematomas. No adverse events associated with administration of TXA occurred. CONCLUSION: Intravenous administration of TXA successfully reduced mean peri-operative blood drainage, total estimated blood loss, pain during the first post-operative days, and haematoma formation in total shoulder arthroplasty.

Arthroscopically assisted fixation is a reliable option for patellar fractures: A literature review.

Proper reduction and stable fixation of articular fractures is essential for an early recovery and to avoid late complications. Arthroscopically assisted techniques for minimally invasive fixation have been introduced to reduce local morbidity and improve anatomic reduction of the fragments. However up to date no clear indications for surgery have been given. In addition, the precise rates of functional outcomes and complications are controversial. The hypothesis was the systematic analysis of the available literature would provide precise indications, outcomes and complications of arthroscopically assisted techniques for patellar fracture fixation. A comprehensive literature review was performed using the keywords "patellar fracture", "arthroscopy" with no limit regarding the year of publication. All the selected articles were in English language and were evaluated with the Coleman score by three independent surgeons. The interclass correlation coefficient between the three examiners was calculated. Six full text articles were retrieved. The initial cohort included 60 patients with a displaced transverse fracture in the majority of the cases. At an average FU of 27.2 months the Lysholm score was 91.3. The rate of complication was 7%; Average Coleman score for the three observers was 55.8±6.5 with an ICC of 0.89, indicating adequate inter-rater agreement. Arthroscopically assisted techniques for minimally invasive fixation of patellar fractures represent a reliable option. The positive clinical outcomes and low rates of complications must be confirmed with further studies including larger series and longer FU. LEVEL OF EVIDENCE: Level IV, systematic review of retrospective series.
