Project description:PurposeTo evaluate whether the bony impingement lesion in elbow osteoarthritis can be removed accurately, as planned during arthroscopy, by using the computer-aided navigation system and performing mock surgery using 3-dimensional (3D)-printed bone models for clinical applications.MethodsWe performed mock surgery using 3D-printed plaster bone models of the humerus of 15 actual patients with elbow osteoarthritis. Two types of experiments were conducted to evaluate the surgical accuracy. Three surgeons performed the mock surgery, each with 15 bone models (total, 45 trials). Surgical accuracy was based on the mean of 45 trials. The differences in surgical accuracy among the 3 surgeons were also evaluated (mean 15 trials). The same surgeon performed 30 trials, and the difference in surgical accuracy between the first and the second halves was also evaluated (mean 15 trials).ResultsThe spatial error in the entire elbow joint was 1.13 mm. In terms of resection volume, a mean of 8% more volume was resected than was planned, and 85% of the planned area was resected. In our experiments, the surgical accuracy was significantly lower in the anterior than in the posterior joint. Intrarater reliability was intraclass correlation (ICC)2,1 0.81 and inter-rater reliability was ICC1,1 0.87.ConclusionsSurgery using computer-aided navigation systems for arthroscopic debridement of the elbow provided accuracy comparable to that in other joints.Clinical relevanceArthroscopic debridement of elbow osteoarthritis requires advanced surgical skills because accurate identification of the bony impingement legion is difficult during surgery. Surgery using computer-aided navigation systems for arthroscopic debridement of the elbow will provide real-time tracking of both the surgical instruments and bony impingement lesions as well as solve the technical difficulties of arthroscopic surgery of the elbow joint.

Project description:The purpose of this Technical Note is to introduce a surgical technique using a fluid pressure pump, mid-lateral portal, and radiofrequency ablation for visualization, assessment, and subsequent, accurate/adequate removal of patellofemoral articular lesions for the treatment of patellofemoral compartment pathology. With the patient in the supine position, and an inflated thigh tourniquet, standard lateral and medial portals are made. The medial-femoral compartment, notch, lateral-femoral compartment, and patellofemoral compartments are assessed. If pathology is seen within the patellofemoral compartment, a mid-lateral portal is made if chondral pathology cannot be addressed thoroughly. Addressing chondral pathology to achieve chondral stability is then performed using a combination of the radiofrequency ablator and chondrotome. This technique provides greater visibility and access to accurately and thoroughly smooth chondral pathology.

Project description:Elbow stiffness occurs as a consequence of multifactorial etiologies and can be broadly classified into either extra-articular or intra-articular contracture. Although nonoperative treatment regimens may prove successful, recalcitrant cases may require operative management. Both open and arthroscopic procedures to address these contractures have been described. Open techniques have historically been the mainstay of surgical management prior to the advent and advancement of arthroscopy. Although often successful, open elbow contracture release introduces added iatrogenic insult to the soft tissue envelope and has the potential to compromise the intraoperatively obtained gains in motion. Arthroscopic contracture release, although not without its own inherent risks, has been shown to be an effective intervention for the release of elbow capsular contractures. Arthroscopic release of the elbow capsule can be challenging, however, because of its thickness and proximity to vital neurovascular structures. The authors describe an adjunctive technique for effectively and efficiently releasing the anterior and posterior capsule under arthroscopic visualization using a 4.5-mm large metal trocar.

Project description:Treatment of primary elbow osteoarthritis in the young active patient less than 50 years old presents a treatment challenge to the practicing orthopaedic surgeon. Following failure of nonoperative management, surgical goals are aimed at reducing pain and improving joint mobility from bony impingement. Arthroscopic osteocapsular arthroplasty is a viable treatment option with few post-operative limitations. In contrast, total elbow arthroplasty is considered a salvage option in this patient population given the activity restrictions imposed. Osteocapsular arthroplasty combines soft tissue and bony debridement, osteophyte/loose body removal, synovectomy, capsular release, and bony contouring of the humerus and ulna to allow impingement-free range of motion.

Project description:Popliteal cysts are characterized by enlargement of the gastrocnemius-semimembranosus bursa. The pathogenesis includes a valvular opening between the knee joint and the bursa, and associated intra-articular pathology may give rise to knee effusion. The mainstay of treatment is conservative. If popliteal cysts are symptomatic, analgesia, aspiration, and steroid injection therapy may be considered, but most recur rapidly. In the past, open excision was an option if they remained symptomatic, but the associated recurrence rate was high. One important reason was that the intra-articular pathology causing the knee effusion was not treated. We present an alternative minimally invasive arthroscopic treatment using dye (methylene blue) directly injected into the cyst, which will leak from the cyst into the joint, to identify the valvular opening. The thickened valve is opened using a basket forceps and then enlarged using a motorized shaver to disrupt the 1-way mechanism between the joint and bursa, as well as to establish an unobstructed freeway connection between them. We also present a safe technique to create a direct posterior portal. Intracystic debridement of the fibrous membrane, nodules, and septa through this portal will decrease the recurrence rate of the popliteal cyst.

Project description:Elbow stiffness is defined as an arc of flexion-extension motion of less than 100° and/or a contracture of more than 30° in flexion. Stiff elbow is common and can be very disabling, preventing individuals from carrying out the basic activities of daily living. The most common cause of stiff elbow is the sequela of an injury, but osteoarthritis can also produce limitations of mobility, which can benefit from surgical treatment The treatment of stiff elbow is initially orthopedic. If the patient still has functional limitations of the elbow after 6 months of suitable rehabilitation treatment , the option of surgical treatment must be considered. Surgical arthrolysis of the elbow can be performed with open surgery as well as with arthroscopic surgery. Good results can be obtained with both techniques achieving a functional arc of at least -30° extension to 130° of flexion. Arthroscopic surgery enables results comparable with those of open surgery but with a lower percentage of complications.

Project description:IntroductionThis study aimed to evaluate the effect of arthroscopic treatment of popliteus tendinitis via an auxiliary extreme lateral approach and to investigate the pathogenesis and treatment of popliteus tendinitis.Materials and methodsFrom 2016 to 2020, arthroscopic popliteus tendon ablation was performed in 15 patients (15 knees) with popliteus tendinitis via an auxiliary extreme lateral approach. Clinical outcomes were assessed using the Lysholm knee scoring scale, the Tegner score, the International Knee Documentation Committee (IKDC) score and the visual analogue scale (VAS) pain score at the 24-month follow-up after surgery.ResultsA total of 15 patients (mean age, 51.1 ± 7.1 years) were included. They had a mean body mass index of 23.8 ± 2.1 kg/m2. The minimum follow-up period was 24 months. Comparing the postoperative state to the preoperative state, the mean postoperative Lysholm score, Tegner score, and IKDC score improved significantly from 70.0 ± 5.0, 3.0 ± 0.9, and 62.3 ± 5.5 to 89.3 ± 4.2, 4.6 ± 0.61, and 80.5 ± 4.4, respectively (p < 0.01). The preoperative VAS score for pain improved from 6.4 ± 0.5 to 0.9 ± 0.4 (p < 0.01). No patients were lost to follow-up.ConclusionsFollowing arthroscopic-assisted treatment, all the patients with popliteus tendinitis achieved satisfactory clinical outcomes in terms of pain relief and improved function.Level of evidenceLevel IV.

Project description:Arthroscopic distal clavicle resection has become an increasingly popular procedure in orthopaedics, and various techniques have been published. Many of the arthroscopic distal clavicle resection techniques that have been reported require visualization from the lateral portal with an anterior working portal to perform the resection. While these techniques have reported high success rates, there is often difficulty in viewing the entire acromioclavicular joint from the 2 standard arthroscopic portals (lateral and anterior). This is due to the medial edge of the acromion blocking the ability to visualize the most superior and posterior portions of the distal clavicle. We propose a technique for arthroscopic distal clavicle resection using an accessory anterior portal.

Project description:Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of degenerative lesions of the wrist and advance Kienböck disease. This procedure has been classically described as an open procedure but recently has been reported as an arthroscopic one. Arthroscopic PRC has several advantages such as minimal damage to the dorsal and volar ligaments as well as there being no need to detach the capsule, which can facilitate earlier mobilization and can decrease postoperative stiffness. In addition, there is a reduced risk of the interosseous posterior nerve being injured, and the proprioception system continues to function. This arthroscopically assisted technique uses the volar central portal as a third portal, which can be useful to remove the volar portions of the bones to view the dorsal areas of the bones and to allow the surgeon to work with 2 instruments at the same time. As a result, the time spent on the procedure can be reduced.

Project description:Arthroscopic elbow surgery is a challenging procedure in part because of the limited intra-articular volume of the joint, the congruence of the elbow articulation, and the close proximity of the neurovascular structures. Arthritic conditions that result in the development of bony prominences and osteophytes are usually amenable to arthroscopic management and include diagnoses such as osteoarthritis, rheumatoid arthritis, and valgus extension overload syndrome. Safe and efficient removal of these osteophytes can be problematic, however, because of technical difficulties often encountered while using arthroscopic burrs and shavers as well as the risks of inadvertent, iatrogenic injury to adjacent articular cartilage and other structures. A valuable and effective technique using small handheld osteotomes to facilitate the arthroscopic removal of intra-articular osteophytes and other bony prominences is described and shown.
