Arthroscopic reconstruction of the TFCC using a free tendon graft
Instability of the distal radioulnar joint (DRUJ) results from injury or laxity of the ligaments responsible for stabilizing the joint. Of note, the triangular fibrocartilage complex (TFCC) plays a crucial role in maintaining DRUJ stability. Sometimes, it may be impossible to repair the TFCC due to degenerative changes in the TFCC. In such cases, DRUJ reconstruction is possible provided that there are no arthritic changes in the DRUJ with the use of tendon graft. The aim of this procedure is to reconstruct the ligament and restore function, thus providing multidirectional stability. This procedure uses a tendon graft, preferably the Palmaris Longus (PL), which is woven through trans-osseous tunnels in the distal radius, converging at the fovea through a distal ulnar trans-osseous tunnel.

Triangular fibrocartilage complex (TFCC) dorsal distal repair
The triangular fibrocartilage complex (TFCC) is actually more complex than it appears to be. Arthroscopy of the wrist has helped to better understand the various insertions of this proximal and distal triangular complex and to detect these lesions. The adapted treatment of these lesions made it possible to prevent failures of the conventional arthroscopic reinsertions with the disappearance of the associated distal ulnar instabilities when only a part of the problem was treated.
The healing potential of the TFCC largely depends on its vascularization. This video shows the arthroscopic repair of a peripheral distal tear of the TFCC with the in-out technique.

Arthroscopic interposition in scapholunate advanced collapse wrist arthritis, stage 2 (SLAC 2)
Scapholunate advanced collapse (SLAC) is a form of degenerative arthritis of the wrist which is commonly a sequela of scapholunate instability. SLAC follows a typical pattern which begins with arthritis of the radial styloid (stage 1). Stage 2 is marked by the involvement of the entire scaphoid fossa and the scaphoid while arthritic changes involve the midcarpal joint in stage 3. Stage 2 SLAC is typically managed with proximal row carpectomy (PRC), which preserves some degree of wrist flexion-extension arc and reduces pain. However, major drawbacks of this procedure are as follows: incongruence between lunate fossa and capitate, subsequent arthritic changes, and reduced grip strength originating from reduced carpal height. This video shows a recently described salvage procedure, namely arthroscopic interposition tendon arthroplasty (AITA), which attempts to preserve wrist motion and carpal height simultaneously restoring radiocarpal joint space and reducing pain, by interpositioning tendon graft in the radiocarpal joint.

Arthroscopic scaphotrapeziotrapezoidal (STT) joint arthroplasty
Scaphotrapeziotrapezoid (STT) joint osteoarthritis is less known than other types of wrist arthritis.
This disease accounts for only 13% of all wrist arthritis sites. Isolated lesions of this joint are rare and their therapeutic management is complex.
The only treatment proposed used to be STT arthrodesis, a technically difficult procedure which caused numerous complications.
Pseudoarthrosis is common, and STT arthrodesis has been incriminated in the occurrence of radioscaphoid osteoarthritis. Techniques of distal resection combined with interposition of biological tissues such as tendons (flexor carpi radialis) was described in the 1990s. In this video, we present arthroscopic interposition of pyrocarbon implant, a safe and convenient technique for patients, with long-lasting favorable results.

Arthroscopic capsuloligamentous suture with anchor for scapholunate dissociation EWAS stage 4
An anatomical and biomechanical study has recently shown that detachment of the scapholunate (SL) ligament from the dorsal capsuloligamentous scapholunate septum (DCSS) and dorsal intercarpal ligament (DIC) worsens scapholunate dissociation. This knowledge has revolutionized the treatment of scapholunate dissociation and formed the basis of the arthroscopic repair of the scapholunate ligament complex. In some large dissociation, we can use a trick, catching a largest part of the dorsal capsule, proximally and distally, in order to help scapholunate reduction when the knot is tightened. Sometimes, the scapholunate ligament is avulsed from the dorsal proximal pole of the scaphoid, and it is necessary to put an anchor at the exact location of the scapholunate attachment into the dorsal scaphoid to allow a dorsal capsuloligamentous repair as for a classical scapholunate tear.

Arthroscopic interposition in SLAC 2 wrist arthritis
Scapholunate dissociation is the most common carpal instability. Scapholunate instability is associated with increased scaphoid flexion and pronation with associated lunate extension. The abnormal kinematics leads to a decrease in surface area contact at the radioscaphoid joint. This abnormal articulation causes an increased concentration of load, leading to the development of degenerative arthritis. In late chronic scapholunate ligament dissociation, when the arthritis appeared (SLAC 2-SLAC 3), treatment often involves heavy palliative techniques such as resection of the first row or four bones fusion. We propose a simpler technique of arthroscopic interposition of a palmaris longus tendon, combined with a wide styloidectomy of scaphoid fossea of distal radius and a dorsal capsuloligamentous repair to stabilize the scapholunate dissociation.

Technique of arthroscopic-assisted foveal repair for TFCC 1B lesion
Three classes of TFCC peripheral 1B tears are recognized in a treatment-orientated algorithm based on arthroscopic findings. Distal tear (class 1), associated with minimal instability of the DRUJ, requires ligament to capsule suture. Complete (class 2) and proximal tears (class 3) are associated with major DRUJ instability and require foveal re-attachment of the TFCC. A new arthroscopic-assisted technique to repair the foveal attachment of the TFCC by using a suture anchor is described. It is indicated for class 2 and 3 TFCC peripheral tears, instead of an open repair. The technique requires a dedicated working portal called Direct Foveal (DF) to approach the ulnar fovea. This DF portal is used to prepare the ligament and bone and to drill and insert a suture anchor loaded with a pair of sutures. Under arthroscopic vision, a suture is passed through each limb of the ligament and tied using a small knot-pusher or a simple mosquito forceps. This arthroscopic technique restores original TFCC anatomy and adequate DRUJ stability with less morbidity and easier rehabilitation as compared to open repair.

Management of scapholunate tears: open versus arthroscopic treatment
The understanding of scapholunate ligament lesions has made great strides in recent years, largely thanks to the work undertaken by the two wrist surgery "heavyweights" who are Dr. Marc Garcia-Elias and Dr. Christophe Mathoulin.
Although they do not use the same approach to treat scapholunate ligament lesions (Marc Garcia-Elias opens the wrist and Christopher Mathoulin tries to process them arthroscopically), they have both reached the same conclusion:
- the scapholunate ligament is more than just an interosseous ligament but rather a real scapholunate ligament complex with intrinsic and extrinsic components;
- proprioception is involved in the stability of scapholunate space;
- and early diagnosis and treatment seem essential to obtain good results.
This peer-to-peer conversation between these two friends is not a battle, but rather an extremely modern development on a long debated topic... have fun!
