Using a combination of three clinical tests for detecting meniscal tears increases the accuracy of the clinical examination.

Background: Recent studies indicate that using combination of two or more clinical tests for detecting meniscal tear gets a higher sensitivity and specificity than any clinical test performed individually.

Methods: The study involved 84 participants who were divided into two groups: the "OP group" consisting of participants diagnosed with a meniscal tear and who consequently underwent arthroscopic meniscectomy, and the "CN group" comprising of healthy participants with no history of knee injury. Two independent observers (orthopedic surgeons) recorded the results of six clinical tests: Thessaly Test, joint line tenderness, McMurray Test, Ege Test, Steinmann I Test, and atrophy of the thigh muscles.

Arthroscopic removal as an effective treatment option for intra-articular osteoid osteoma of the knee.

Background: Intra-articular osteoid osteoma (iaOO) can be found in 5.2% up to 10% of cases. They may cause non-specific symptoms, mimicking degenerative or traumatic pathologies.

IS THERE ANY ROOM FOR TENDOSCOPY IN THE SURGICAL TREATMENT OF POSTERIOR TIBIAL TENDON INSUFFICIENCY?

Posterior tibial tendon insufficiency (PTTI) is nowadays considered to be the main cause of adult-acquired flatfoot deformity (AAFD). The purpose of this study is to report the outcomes of tendoscopic treatment of tibialis poste- rior tendon (TP) in eleven patients with stage 1 or 2 PTTI and failed prior conservative treatment. Tendoscopy was carried out as a solitary procedure in 8 patients, while in 3 patients additional procedures such as ,,mini-open" tubularization of TP or anterior ankle arthroscopy were necessary.

Periarticular osteoid osteoma of the ankle: a report of nine arthroscopically treated patients.

Periarticular osteoid osteoma often presents with unspecific clinical symptoms, mimicking other clinical conditions. This can lead a clinician to a ''diagnostic side path'' and a delayed or missed diagnosis compared with extra-articular osteoid osteoma. We report the cases of 9 patients with a mean age of 22 (range 14 to 32) years who were diagnosed with periarticular osteoid osteoma of the ankle and were surgically treated in our department during a 12-year period.

[Hip arthroscopy].

In the last ten years, hip arthroscopy has been developing intensively and it is rapidly gaining primacy in the treatment of various injuries and damages to the hip itself and its immediate vicinity. The basic advantage of hip arthroscopy surgery versus classic open surgery is avoiding an open dislocation of the hip and, thus, reducing patient's morbidity and accelerating his/her rehabilitation, which leads to a quicker return to everyday activities. The success of arthroscopic surgery depends on the correct indication for the surgery and on the experience and the skill of the operator.

Current practice variations in the management of anterior cruciate ligament injuries in Croatia.

Aim: To investigate current preferences and opinions on the diagnosis, treatment and rehabilitation of patients with anterior cruciate ligament (ACL) injury in Croatia.

Methods: The survey was conducted using a questionnaire which was sent by e-mail to all 189 members of the Croatian Orthopaedic and Traumatology Association. Only respondents who had performed at least one ACL reconstruction during 2011 were asked to fill out the questionnaire.

Synovial chondromatosis of the elbow.

Synovial chondromatosis (SC) is a rare, mostly benign proliferation of the synovium of the joint, tendon or bursa which results in the formation of loose bodies. It can appear in one of 33 described localisations, but it is most common in the knee. In our study we gathered a group of 7 patients (6 male and 1 female) with SC of the elbow, which underwent arthroscopic surgery of the elbow, performing both removal of the loose bodies and complete synovectomy.

[Ligament which deserves attention--medial patellofemoral ligament].

There has been increasing interest in investigating the medial patellofemoral ligament (MPFL) during the last fifteen years. This is due to the recognition of the MPFL as the primary static soft-tissue restraint to lateral patellar displacement and the association of MPFL injury with primary traumatic patellar dislocation. The MPFL often heals poorly and thus rarely regains its full function.

[Eccentric exercises in the treatment of overuse injuries of the musculoskeletal system].

Overuse injuries of the musculoskeletal system are a common problem in both general population and among athletes. Researches made in the last decade have shown that overuse injuries are mainly caused by degenerative changes and not inflammation, as was thought before. Although they can be present everywhere in musculoskeletal system, overuse injuries are most often seen on tendons.

Removal of osteoid osteoma of the tibia using two-portal posterior ankle arthroscopy.

The case of a 30-year-old male with a history of pain in his left ankle is presented. The pain was described as predominantly nocturnal and frequently relieved by the use of nonsteroidal anti-inflammatory drugs. Computed tomography indicated a diagnosis of an osteoid osteoma in the posteromedial portion of the tibia.

Arthroscopic treatment of localized and diffuse pigmented villonodular synovitis of the knee.

Pigmented villonodular synovitis (PVNS) is a rare proliferative synovial disorder of uncertain etiology. Two forms of this disorder, a localized (LPVNS) and diffuse (DPVNS) form, are well differentiated. The therapy of choice for LPVNS is arthroscopic partial synovectomy with excision of the lesion.

[Arthroscopy of the elbow].

Elbow arthroscopy has become an indispensable method of surgical care of injuries and their consequences and damages that affect the elbow. The advantages of elbow arthroscopy in comparison to classical open surgery are multiple. Primarily, arthroscopy allows an excellent view of intra-articular structures and thus a detailed overview of the entire joint which enables us to perform complete surgery without opening the joint.
