OBJECTIVE
To describe the technique to perform diagnostic standing scapulohumeral joint needle arthroscopy with a 1.2-mm-diameter arthroscope in horses.
STUDY DESIGN
Experimental study.
ANIMALS
Eight thoracic limbs in phase 1 and six horses in phase 2.
METHODS
In phase 1, the feasibility of the technique was evaluated by using a craniolateral arthroscopic approach. An evaluation of the visible structures of the scapulohumeral joint was performed with both a needle arthroscope and a 4-mm-diameter arthroscope. In phase 2, the technique was performed in six healthy sedated horses to validate the technique in live animals and to report any complications or limitations.
RESULTS
In phase 1, joint evaluation was similar between arthroscopes and allowed complete evaluation of approximately the lateral half of the humeral head and the lateral glenoid rim. In phase 2, all joints were successfully accessed, and fluid extravasation was mild. Arthroscopic visualization was complete for the centrolateral aspect of the joint in all horses and either complete (3/6) or partial (3/6) for the craniolateral and caudolateral structures, respectively. The procedure was rapidly performed and well tolerated, and no postoperative complications occurred.
CONCLUSION
The described technique was simple and allowed direct inspection of the scapulohumeral joint. Nonetheless, the standing nature of the technique prevents evaluation of the medial aspect of the humeral head and most of the glenoid cavity.
CLINICAL SIGNIFICANCE
Needle arthroscopy of the scapulohumeral joint is feasible in horses and offers a diagnostic technique that may improve the surgeon's diagnostic ability for certain shoulder pathologies.

BACKGROUND
Hip arthroscopy has gained popularity among the orthopedic community and a precise assessment of indications, techniques and results is constantly brought on.
METHODS
In this chapter the principal standard entry portals for central and peripheral compartment are discussed. The description starts from the superficial landmarks for portals placement and continues with the deep layers. For each entry point an illustration of the main structures encountered is provided and the principal structures at risk for different portals are accurately examined. Articular anatomical description is carried out from the arthroscope point of view and sub-divided into central and peripheral compartment. The two compartments are systematically analyzed and the accessible articular areas for each portal explained. Moreover, some anatomical variations that can be found in the normal hip are reported.
CONCLUSION
The anatomical knowledge of the hip joint along with a precise notion of the structures encountered with the arthroscope is an essential requirement for a secure and successful surgery. Level of evidence: V.

We experienced a case of humeral head impression fracture accounting for approximately 20% of the anterior articular surface. Open reduction and internal fixation of the proximal humeral fracture combined with arthroscope-assisted reduction and internal fixation of the humeral head impression fracture were performed, and good clinical and radiographic outcomes were obtained. Untreated impression fracture may be a potential risk for subluxation or osteoarthritis. However, our arthroscopic approach is minimally invasive and allows for the prevention of these risks.

Arthroscopic subacromial decompression with acromioplasty is among the most commonly performed arthroscopic shoulder procedures and is an important aspect of any orthopaedic surgeon's armamentarium. This procedure is indicated for refractory subacromial bursitis and subacromial impingement. It is also a routine portion of rotator cuff repair exposure. The procedure aims to remove the subacromial bursa, which can serve as a pain generator, as well as any osteophytes on the undersurface of the acromion, which can lead to impingement and, in some circumstances, bursal-sided rotator cuff tears. Multiple randomized clinical trials have demonstrated no benefit for this procedure as an initial treatment in patients with subacromial bursitis, and thus this procedure is indicated only for patients with refractory subacromial bursitis. The steps of this procedure include (1) placement of the arthroscope in the subacromial space and establishment of a lateral working portal, (2) performance of a thorough subacromial bursectomy, (3) achievement of hemostasis and subperiosteal exposure of the undersurface of the acromion, and (4) smoothing of the undersurface of the acromion and removal of any anterolateral osteophytes. Outcomes after this procedure have shown significant increases in UCLA (University of California at Los Angeles), Constant, visual analog pain scale, and Simple Shoulder Test scores over the preoperative status. Complications, while infrequent, are mostly related to overresection or underresection of the acromion.

Acute acromioclavicular (AC)-joint dislocations are common injuries of the shoulder girdle. Surgical repair is indicated for acute high-grade (Rockwood types IV, V, and VI) AC-joint injuries. The best treatment for type III is still controversial, but young and active patients with this type of injury might benefit from a surgical AC-joint stabilization. Surgery should be performed within the first 3 weeks after the injury since the biological healing potential decreases with time. Acute AC-joint separation is diagnosed by clinical examination and radiography. Vertical translation anteroposterior stress views with a 10-kg load are used to grade the injuries. Bilateral lateral stress (Alexander) views are used to evaluate dynamic horizontal translation qualitatively. Arthroscopic techniques for AC reconstruction have become more popular in recent years because they are minimally invasive; they allow treatment of concomitant glenohumeral lesions; and they can be performed in one step, with insertion of implants that do not have to be removed later. The arthroscopically assisted double-button technique with an additional AC cerclage was developed to stabilize the AC joint by internal bracing of the torn ligaments. The procedure consists of the following steps. Step 1: With the patient in the beach-chair position, a 2-cm incision is made on top of the clavicle and posterior and lateral viewing portals as well as an anteroinferior working portal are created. Step 2: With the arthroscope in the lateral portal, the subcoracoid bursa and the base of the coracoid are dissected with a radiofrequency ablation device through the anteroinferior portal. Step 3: Coracoclavicular drilling is done with use of a drill guide and under arthroscopic and image-intensifier control. After overdrilling of the Kirschner wires, Nitinol suture passers are introduced and retrieved via the anteroinferior portal. Step 4: Transclavicular and transacromial drill-holes are established for the AC cerclage. Step 5: The 2 double-button devices are attached to the Nitinol suture passers, and the inferior buttons are shuttled through the clavicle and coracoid and then placed parallel to the coracoid base. Step 6: The sutures are tightened, and an anatomical vertical reduction of the AC joint is achieved. Step 7: A triangular acromioclavicular nonabsorbable cerclage tape is used for horizontal stabilization. Step 8: The clavicular incision is closed in 2 layers, including the repair of the deltotrapezoidal fascia and the arthroscopic portals, in a standard fashion. The combined arthroscopically-assisted and image-intensifier-controlled double-button technique with an additional AC cerclage is a safe procedure that enables an anatomical reduction of the AC joint and yields good to excellent clinical results.

BACKGROUND
Dynamic radiocarpal instability is one of the causes of post-trauma radial-sided wrist pain. It is not easy to diagnose and may possibly be overlooked. The key ligaments responsible for dynamic radiocarpal instability are the radioscaphocapitate (RSC) and long radiolunate (LRL) ligaments. Tensioning of these 2 ligaments could be a method of treatment for dynamic carpal instability. We proposed a method for arthroscopic thermal shrinkage of these 2 ligaments, and for setting a landmark arthroscopically to facilitate identification of these 2 ligaments during the combined open suture tensioning procedure.
METHODS
Between January 2016 and May 2020, 12 patients treated with this method were enrolled. The mean age was 33.3 years (range, 18-57 years), and the mean duration from injury to operation was 7.8 months (range, 3-25 months). The diagnosis was mainly depended on the physical examinations and confirmed under arthroscopy. The mean follow-up was 17.7 months (range, 12-26 months).
RESULTS
All the patients had marked improvement of pain, grip strength, the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), and the radiocarpal stability. The wrist range of motion showed significant decrease around 5 in both flexion and extension and around 4 in the ulnar deviation at the final follow-ups. All patients were able to return to their previous full level of work and activities.
CONCLUSIONS
We conclude that arthroscopic thermal shrinkage combined with open suture tensioning can be effective in treating dynamic carpal instability, while the arthroscopic-assisted landmark setting can help identify the accurate location of the RSC and LRL ligaments without dissecting too much soft tissue.

Review
Sterility errors during orthopaedic procedures can be stressful for the surgeon or scrub nurse and lead to devastating infectious complications and liability issues. This paper aims to review orthopaedic surgeon practices and propose possible attitudes to adopt. Out of 1023 questionnaires sent, 170 orthopaedic surgeons answered a Volunteer Feedback Template (multiple-choice test) by SurveyMonkey® (San Mateo, CA, USA) anonymously. The survey questioned surgeon's response to a sterility mistake during a standard total knee joint replacement, trauma surgery and arthroscopic procedure. Those "sterility mistake" situations occurred when there was contamination of 1) a sterile polyethylene (PE) 2) a sterile targeting device, and 3) an arthroscope. When the definitive PE is contaminated, and if a new definitive PE will only be available 2 hours later, 52% of surgeons would wait for the new definitive PE (p<0.001). In the same situation, if a new PE will only be available in 4 hours, the results showed a significant difference favoring two other options: "putting a definitive PE one size smaller or bigger with balance adjustment" (31%); and "leaving the provisional PE in the joint, closing the wound and re-operating the patient in the coming days when the definitive PE arrives" (29%) (p<0.001). When the new PE is only available 24 hours later results were 34% and 31%, respectively (p<0.001). In the case of a surgical procedure for a classic intertrochanteric fracture, if the carbon fiber targeting device is contaminated, most surgeons (50%) chose to put the nail without the targeting device and finish the surgery (p<0.001). When the arthroscope is desterilized, 39% of participants would wait until the arthroscope has been sterilized again (approximately 2 hours), while 24% would use another procedure (p<0.001). Sixty-two percent of surgeons would adapt their strategy. No clear trend could be identified in terms of antibiotic treatment following a sterility error. There are no established guidelines on how to deal with sterility breaches during surgery and on the antibiotic strategy following the prolonged surgical time resulting from the delay for a new implant. The most common course of action chosen by participating surgeons is detailed in our expert decision tree - if another sterile component is not available within 2 hours - : insertion of another PE size, rescheduling the operation, adapting the surgical technique (for trauma procedures), or soaking the arthroscope in disinfectant solution. As instances of contamination cannot be avoided, it is recommended to have a minimum of two copies of sterile PE implants, arthroscopes or targeting devices readily available before surgery begins-.

Arthroscopic posterior cruciate ligament (PCL) reconstruction is a technically demanding procedure, particularly with respect to tibial footprint debridement and tibial tunnel placement, where iatrogenic damage to anatomic structures is a well reported complication and incorrect tunnel placement can have functional implications. Preparation of the tibial component often involves switching between 30° and 70° arthroscopes and frequent portal swapping and reorientation, which can be inefficient and time-consuming. As the technology and picture resolution of needle arthroscopy has improved, its clinical application has widened. This manuscript describes the use of needle arthroscopy-assisted arthroscopic PCL reconstruction for optimal visualization of the PCL tibial footprint using an accessory posterolateral portal, while obviating the need of both 30° and 70° arthroscopes.

BACKGROUND
Arthroscopic lysis of adhesions is a treatment option for patients with painful, stiff knees as a result of arthrofibrosis following knee arthroplasty, in whom prior manipulation under anesthesia (MUA) has failed. Typically, nonoperative treatment in these patients has also failed, including aggressive physiotherapy, stretching, dynamic splinting, and various pain-management measures or medications. Range of motion in these patients is often suboptimal, and any gains in flexibility will likely have hit a plateau over many months. The goal of performing lysis of adhesions is to increase the range of motion in patients with knee stiffness following total knee arthroplasty, as well as to reduce pain and restore physiologic function of the knee, enabling activities of daily living.
DESCRIPTION
This is a straightforward surgical technique that can be performed in a single stage. The preoperative range of motion is documented after induction of general anesthesia. The procedure begins with the establishment of standard medial and lateral parapatellar arthroscopic portals. A blunt trocar is introduced into the knee, and blunt, manual lysis of adhesions is performed in the suprapatellar pouch and the medial and lateral gutters with use of a sweeping motion after piercing and perforating the scarred adhesive bands or capsular tissue. Next, the arthroscope is inserted into the knee, and a diagnostic arthroscopy is performed. Bands of fibrous tissue are released and resected with use of electrocautery and a 4.0-mm arthroscopic shaver. Next, the posterior cruciate ligament (PCL) is visualized in full flexion. If PCL tightness is observed, the PCL can be released from its femoral origin until the flexion gap is increased. This portion of the procedure can include either partial or full release of the PCL, as indicated. Next, the arthroscope is removed and the ipsilateral hip is flexed to 90° for a standard MUA. Gentle force is applied to the proximal aspect of the tibia, and the knee is flexed. After completing the MUA, immediate post-intervention range of motion of the knee is documented, and the patient is provided with a continuous passive motion (CPM) machine set to the maximum flexion and extension achieved in the operating room.
ALTERNATIVES
Nonoperative treatment of a stiff knee following total knee arthroplasty is well documented in the current literature. Range of motion has been shown to increase in patients undergoing proper pain management, aggressive physical therapy, and closed MUA in the acute postoperative setting. Additionally, more severe cases of established arthrofibrosis despite prior MUA can be treated with an open lysis of adhesions.
RATIONALE
Arthroscopic lysis of adhesions with PCL release versus resection has been well described previously. This procedure has been shown to benefit patients in whom initial nonoperative treatment has failed. Additionally, this procedure is not limited to the immediate acute postoperative period like standard MUA. To our knowledge, no technique video has been published outlining arthroscopic lysis of adhesions for a stiff knee following total knee arthroplasty.
EXPECTED OUTCOMES
This procedure has been shown to provide an immediate and lasting improvement in the flexion and extension arc of the knee, as well as improved functional outcomes. Patients should be educated that improvements gained in the operating room must be sustained through physical therapy. In a study of 32 patients who underwent arthroscopic lysis of adhesions for moderately severe arthrofibrosis following a total knee arthroplasty, Jerosch and Aldawoudy reported a mean postoperative flexion of 119° in the operating room and 97° at the time of the latest follow-up. Eight patients with extensor lag showed improvement from 27° to 4°. Average Knee Society scores improved from 70 points preoperatively to 86 points at the time of the latest follow-up. Their article showed that arthroscopic treatment of stiffness following total knee arthroplasty is a safe and effective form of treatment.
IMPORTANT TIPS
Perform manual lysis of adhesions with a trocar prior to inserting the arthroscope in order to improve visualization and access.Utilize all portals and accessory portals interchangeably in order to improve access.Prescribe physical therapy with or without CPM machine immediately following surgery in order to maintain correction.Utilize pump inflow in order to help distend the tightened capsule.Protect the prosthetic surface from scratches during portal establishment.Loss of flexion implies scarring in the suprapatellar pouch and/or intercondylar notch, or PCL tightness.Loss of extension implies a tight posterior capsule, posterior osteophytes, or scarring of the PCL stump.A motorized shaver is the best tool for treatment of dense fibrous tissue, but be sure not to scratch metal total knee components.
