Tenosynovial giant cell tumor (TGCT) is a rare disease characterized by the proliferation of the synovial membrane of a joint, tendon sheath, or bursa. TGCTs in joints are subdivided into the diffuse ...or localized type. The localized TGCT most frequently affects the knee and may occur in any knee compartment. The most common localization is the Hoffa's fat pad, followed by the suprapatellar pouch and the posterior capsule. Here, we describe a case of a histopathologically proven TGCT of the knee, found in an unusual localization in the deep infrapatellar bursa, which was diagnosed by magnetic resonance imaging. The tumor was entirely arthroscopically resected. The patient had no further complaints following the operation, and there was no recurrence at the 18-month follow-up. Even though TGCT of the knee is uncommon, it should not be overlooked by orthopedic and trauma surgeons, and excision should be regarded as a reliable treatment option. The form of surgical treatment, either open or arthroscopic, should be determined based on a combination of the surgeon's preference and the best approach to the anatomical location of the disease.

Ankle arthroscopy is a surgical technique still most commonly performed with a tourniquet. In 2017, we published a randomized controlled trial comparing anterior ankle arthroscopy with and without ...the tourniquet use. The results showed feasibility of performing the anterior ankle arthroscopy without the tourniquet, as well as comparable functional outcomes at 3- and 6-month follow-up visits, regardless of the tourniquet use. The aim of the current study was to evaluate mid-term functional outcomes after a 5-year period and to document patient satisfaction with the surgery. All 49 available patients from the original study were asked to attend examination at the 60-month follow-up visit. Patients were assessed with the same functional scores, as well as with additional Munich Ankle Questionnaire (MAQ) to assess the postoperative subjective and objective outcome and Abdelatif questionnaire to evaluate patient satisfaction. Any new complications were noted. At the 60-month follow-up visit, 39 (79.6%) patients were available for examination. No significant difference was found between the groups regarding the functional outcomes or the MAQ. In comparison with the 3- and 6-month follow-up visits, no further improvement or decline of functional outcomes was present. High patient satisfaction was found in both groups. No new complications were noted during the follow-up period. Similar improvement in both groups reveals that the anterior ankle arthroscopy can be performed without the tourniquet with no negative impact on mid-term functional outcomes. In addition, high patient satisfaction can be expected even after 5 years from surgery, regardless of the tourniquet use.
Background:
Primary synovial chondromatosis (PSC) is a progressive disorder of unknown etiology resulting in formation of multiple loose bodies. If left untreated, it may lead to degenerative changes ...or malignant transformation to chondrosarcoma.
Methods:
Seventeen patients who underwent combined posterior and anterior ankle arthroscopy within the same operative session and had histologically confirmed PSC were included in this retrospective study. American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score was used to evaluate ankle function preoperatively and at a final follow-up. A 3-question survey was used to evaluate patient’s satisfaction at the final follow-up.
Results:
In 14 patients, loose bodies were found in both compartments of the ankle, in 2 only in the anterior compartment, and in 1 only in the posterior compartment. All patients had evident signs of synovial inflammation in both compartments. The AOFAS Ankle-Hindfoot score increased from the preoperative median score of 65 (range, 29-90) to 95 (range, 65-100) at the final follow-up. Fourteen patients reported they were extremely satisfied with the outcome, 1 was moderately satisfied, and 2 were dissatisfied. No cases of recurrence of synovitis or loose body formation were noted, nor any signs of malignant transformation during the follow-up period.
Conclusion:
We believe the risk of recurrence of PSC, which is in close relation to malignant transformation, can be minimized by performing a complete synovectomy of the ankle. Our experience and review of literature makes us believe that ankle PSC should be regarded as a whole joint disorder. Performing a combined posterior and anterior arthroscopic procedure within the same operative session should always be considered in patients with ankle PSC.
Level of Evidence:
Level IV, retrospective case series.
Background:
We hypothesized that peroneal tendons disorders are more commonly associated with anatomical variations, which could overcrowd the retrofibular groove.
Methods:
This single-center ...retrospective case study covered 84 consecutive cases that had undergone peroneal tendoscopy. Peroneal tendoscopy was performed on 82 patients, predominantly female (3:1) with a median age of 46 years. The preoperative evaluation and all the procedures were performed by a single surgeon using a standardized technique.
Results:
Two patients required revision surgery 8 and 52 months after the index procedure due to persistent posterolateral ankle pain. Peroneal tendoscopy was performed as a solitary procedure in 45.1% (37/82) of cases, while the remaining cases involved peroneal tendoscopy as a supplementary procedure. Low-lying peroneus brevis muscle belly (LLMB) was the most common finding in this series in 53.7% (44/82) of cases. In 41.5% (34/82) of cases, longitudinal tears of the peroneus brevis tendon were noted. Some patients presented with more than 1 concomitant peroneal tendon pathology. The LLMB was observed in 23.5% (8/34) of cases with a longitudinal tear of the peroneus brevis tendon.
Conclusion:
Peroneal tendon anatomical variations, especially LLMB, were associated with the presence of peroneus brevis tendon ruptures and intrasheath peroneal tendon subluxations as well as posttraumatic posterolateral ankle pain. Due to high rates of undiagnosed and misdiagnosed cases of LLMB preoperatively, we believe special care should be taken to recognize it during tendoscopy. Peroneal tendoscopy is a high-efficiency, low-complication method to treat some peroneal tendon conditions.

The purpose of this study was to evaluate the 4-year survivorship of total knee arthroplasty (TKA) of a single manufacturer and determine whether failure rates differ between the cruciate-retaining ...(CR) and the posterior-stabilised (PS) type of implant. In addition, possible causes of revision were analysed as well. A retrospective analysis of 580 TKAs, with either the CR or the PS type of the Biotech Future Knee endoprosthesis (BIOTECH GmbH, Garbsen-Berenbostel, Germany) was performed. The 4-year survivorship for revision of any cause in all cases was 89.14%, with aseptic loosening being the most common cause of revision (53.9%). Regarding the type of implant model, the revision rate was higher in the PS group compared to the CR group (13.7% to 8.0%, respectively, p=0.027). The Cox regression models suggested that the type of prosthesis was a significant predictor of the need for revision (HR, 0.442; 95% CI, 0.234-0.833). In conclusion, our study has shown higher revision rates with the PS implant type when compared to the CR implant type with a higher rate of aseptic loosening in the PS group. Further studies are needed to determine the cause of these results and to investigate whether the problem is specific to the implant.
ankle impingement syndrome. However, other indications of the posterior part of the ankle/hindfoot remain mostly uninvestigated. The aim of this study is to investigate the indications for posterior ...ankle/hindfoot arthroscopy performed as a solitary procedure and to report the outcomes. A total of 71 patients, who had undergone this procedure in our department over a period of nine years, were analysed. In all cases, the van Dijk et al. technique was followed. The most prevalent indication for posterior/hindfoot arthroscopy remains posterior ankle impingement syndrome in 59.15% of cases. Other indications included ten various posterior ankle/hindfoot pathologies, with the subtalar joint contracture being the most common one (15.49%). During the mean follow-up period of 79 (range, 24 - 127) months, there were 2 minor complications noted, both pertaining to transitory sensory deficits. The total median AOFAS Ankle-Hindfoot score significantly improved from 69 to 98, with the improvement noted regardless of the indication. The satisfaction rate with the procedure was 98.59%. This study has shown that posterior ankle/hindfoot arthroscopy is an efficient and safe orthopaedic tool for the treatment of various posterior ankle and hindfoot articular and periarticular pathologies.
Osteochondritis dissecans (OCD) of the elbow mainly occurs in overhead athletes (OHAs). This narrative review aimed to comprehensively analyze the epidemiological data, etiological factors, clinical ...and imaging features, treatment options, and outcomes of OHAs with the diagnosis of elbow OCD. A literature search was performed in PubMed/MEDLINE, Scopus, and Web of Science. Individuals with elbow OCD were usually 10-17 years of age with incidence and prevalence varying between studies, depending on the sport activity of the patients. The etiology of OCD lesions is multifactorial, and the main causes are believed to be repetitive trauma, the biomechanical disproportion of the articular surfaces, poor capitellar vascular supply, and inflammatory and genetic factors. Athletes usually presented with elbow pain and mechanical symptoms. The mainstay for the diagnosis of elbow OCD is MRI. The treatment of elbow OCD lesions should be conservative in cases of stable lesions, while various types of surgical treatment are suggested in unstable lesions, depending mainly on the size and localization of the lesion. The awareness of medical practitioners and the timely diagnosis of OCD lesions in OHAs are key to favorable outcomes.
Background:
A tourniquet is usually used during anterior ankle arthroscopy to allow for improved visibility and reduced operation time. However, this has not been demonstrated to be true in clinical ...studies on knee arthroscopy, while limited tourniquet time has been described as a possible factor to lower the complication rate of ankle arthroscopy. The purpose of this randomized controlled trial was to examine the effect of tourniquet use on arthroscopic visualization, operative time, postoperative intra-articular bleeding, postoperative pain scores, and outcome of anterior ankle arthroscopy.
Methods:
A consecutive series of 50 patients who were scheduled for anterior ankle arthroscopy were randomized to have the surgery done either without the tourniquet inflated (25 patients) or with the tourniquet inflated (25 patients). The patients were evaluated by the course of the surgery, postoperative intra-articular bleeding, and pain during the early postoperative period, and subjective and objective functional scores were used to evaluate the condition of the ankle before and 3 and 6 months after the surgery. Forty-nine patients were present at the final follow-up, 6 months after the surgery.
Results:
The results between the groups were comparable regarding the duration of the operative procedure, consumption of sterile saline, visualization, and functional scores. A notable difference between the groups in favor of the nontourniquet group was present regarding postoperative bleeding but was not statistically significant. A statistically significant difference in favor of the nontourniquet group was found regarding postoperative pain during several days in the early postoperative period.
Conclusion:
Our study showed that anterior ankle arthroscopy was performed adequately without the use of a tourniquet and that it had the same operative course as cases in which the tourniquet was used and functional outcomes that were not worse than cases in which the tourniquet was used.
