Technique Video Video 1 Arthroscopic remnant preserving PCL reconstruction with reverse passage of the graft. The left knee is being operated on. In the beginning, PCL injury is confirmed. Autograft is prepared from semitendinosus and gracilis tendon, which are quadrupled, and is strengthened using Hi-Fi Tape. Suture disc is implemented on the fem...

Massive irreparable rotator cuff tears (RCT) remain challenging for orthopaedic surgeons all over the world and the best treatment options are still widely discussed. Whereas conservative treatment plays an irrelevant role due to its small efficacy in reducing pain and improving shoulder function, surgery remains a gold standard in the management o...

Osteochondral defects of the knee are common in orthopaedic patients. They are challenging to treat, especially in young, highly demanding patients who do not qualify for arthroplasty. Among the many possibilities to treat osteochondral lesions presented so far, none is ideal. Because of the poor healing potential of cartilage, treatment outcomes s...

Injuries to the posterolateral corner (PLC) of the knee may have a devastating impact on whole joint. Posterolateral rotatory instability, despite getting more and more popular among orthopedic surgeons, still remains challenging to diagnose and even more challenging to treat. Available surgical techniques are demanding and require advanced surgica...

Purpose: To present the arthroscopic “PCL envelope lack sign” (PELS) and to calculate its diagnostic characteristics in chronic PCL insufficiency. Methods: Recordings of knee arthroscopies performed in a single clinic between April 2015 to March 2020 were retrospectively evaluated, searching for the “PCL envelope”. It was defined as a “soft tissue...

Tibial plateau fractures occur in both old and young patients and may be caused by low-energy trauma, as well as high-energy trauma. Owing to the variety of injury mechanisms and fracture patterns, tibial plateau fractures are very challenging to treat. One of the most demanding fractures is the type III fracture according to the Schatzker classifi...

Autogenous quadriceps tendon-bone graft is a great choice for knee reconstruction procedures, including primary and revision reconstructions of both anterior cruciate ligament (ACL) and posterior cruciate ligament. In primary ACL reconstruction, one of the most frequently performed procedures in orthopaedic surgery, it is gaining more and more popu...

"O barku od podstaw" [Shoulder from basics] is an educational book created by Polish Student Orthopaedic Society under the editorship of Adrian Góralczyk and Marcin Mostowy. It is available on the Society website under the link http://osto.edu.pl/projekty-osto/o-barku-od-podstaw/

Classically, external snapping hip syndrome (ESHS) is considered to be caused by friction of a tight iliotibial band (ITB) over the greater trochanter (GT), which leads to pain, inflammation, and palpable or audible snapping. Surgical treatment remains a gold standard in patients resistant to conservative measures. Many surgical procedures addressi...

The rapid development of anterior cruciate ligament (ACL) reconstruction and repair techniques has significantly improved the outcomes of these procedures. However, there is still some place for how to improve surgical techniques to limit the amount of revision surgeries. Over the past decade, biological solutions and methods of ligament remodeling...

Excessive knee pivoting that causes a complete anterior cruciate ligament (ACL) tear may result in a subchondral compression fracture on the lateral femoral condyle after impacting the lateral tibial condyle. Because this mechanism is similar to the humeral head that has an impact on the glenoid during an anterior shoulder dislocation, such an oste...

Since the role of the menisci has been better understood, there is a trend toward the meniscal repair rather than meniscectomy in the management of meniscal tears. Although numerous techniques of meniscal repair have been described and many authors advocate for and against each of them, no single method is universally accepted. The all-inside repai...

PurposeSpontaneous osteonecrosis of the knee (SONK) is said to be a relatively common disease which may lead to an end-stage osteoarthritis of the knee. The aim of this paper was to review the literature on this field published until now, discuss the results of both conservative and surgical treatment options, as well as to introduce new methods of...

Ankle instability is due to repetitive inversion injuries and is usually treated conservatively; however, after repeated sprains, chronic instability occurs and usually requires a surgical procedure. Recently, arthroscopic repair of a torn anterior talofibular ligament (ATFL) has become more popular owing to its minimal invasiveness and high effica...

Avulsion fractures of the posterior cruciate ligament (PCL) are a rare, but serious, knee pathology. Early surgical treatment is regarded as necessary to maintain knee stability. Recommended management involves open reduction with internal fixation through a posterior approach. However, open surgeries are associated with a greater risk of complicat...

High tibial osteotomy (HTO) is a commonly performed surgical procedure. Although it is well-known that the superficial medial collateral ligament (sMCL) should be released during HTO, there is still no agreement on performing its reattachment. Considering the function of the sMCL, after its release during HTO, increased medial joint instability may...

Even though structures of the medial side of the knee have a high potential to heal without surgery, in some circumstances injuries of this region may lead to development of chronic medial and anteromedial rotatory instability (AMRI). In those circumstances, surgery should be performed. Current-day surgical techniques are focused on recreating the...

Tibial plateau fracture treatment remains challenging for orthopaedic surgeons around the world, especially in case of type III fractures according to the Schatzker classification, which are a pure depression of the lateral tibial plateau. Whereas open surgical procedures are associated with increased soft-tissue trauma because of the extent of the...

Popliteal cysts can be an oppressive symptom in patients with concomitant intra-articular knee pathologies. Because isolated treatment of intra-articular lesions is usually not sufficient to resolve the problems associated with a large symptomatic popliteal cyst, a popliteal cyst should be concurrently addressed with other knee pathologies to maxim...

The medial meniscus is one of the most commonly injured structures in the knee. When the importance of its proper function is well understood, an adequate management in meniscus tear is a key issue for whole knee joint well-being. Although it has been proven that meniscal repairs have better long-term results than meniscectomy, there is still no co...

As the anatomy and biomechanics of the posterolateral corner (PLC) of the knee have become better understood, the importance of the PLC's proper function has become a more frequently raised subject. Misdiagnosed chronic posterolateral instability may lead to serious consequences, including cruciate ligament reconstruction graft failure. It has been...

Knee flexion contracture is a clinically important complication that can be observed after trauma, after knee surgery, or as a result of osteoarthritis. When it is left untreated, knee shearing forces increase not only in the affected joint but also in the contralateral knee, leading to mechanical overload in both limbs. Conservative management is...

The injuries of the posterolateral corner (PLC) of the knee often remain misdiagnosed. Because most structures in this anatomical region have low potential to heal, the posterolateral rotational instability results in a deterioration in patient quality of life, impaired biomechanics of the knee, and increased tension on other ligaments and the meni...

Despite the development in shoulder surgery, massive irreparable rotator cuff tears still remain challenging for orthopaedic surgeons. Many surgical methods are addressed to this kind of pathology, but each of them has its own limitations. We decided to fuse the ideas of superior capsular reconstruction, “GraftJacket” technique, and partial rotator...

Comprehensive radiographic analysis of total knee arthroplasty performed traditionally and with the use of Computer Assisted Navigation (CAN) is presented. The aim of this study was to compare the precision of implant alignment considering two operating techniques. The analyzed material consisted of 100 radiograms of patients operated on traditiona...
