Symptomatic genu recurvatum is defined as greater than 5° of knee hyperextension and can be caused by osseous deformity, soft tissue laxity, or a combination. Common symptoms include pain, weakness, instability, decreased range of motion, leg length discrepancy, and stretching of the posterior capsuloligamentous structures of the knee. In instances where the genu recurvatum is caused by reverse tibial slope, literature supports the use of anterior opening-wedge proximal tibial osteotomy (OW PTO) to treat genu recurvatum by increasing tibial slope. Correction of anterior slope to a more anatomic, posterior orientation allows any stressed ligaments to return to their normal tension and restores the native biomechanics of the knee. The primary indication for OW PTO is genu recurvatum that is nonresponsive to physical therapy or genu recurvatum with concurrent ligamentous injury. The heel-height test provides an objective assessment for the identification and measurement of knee hyperextension. 2 guide pins are placed parallel to the tibial plateau, engaging the posterior cortex. A small micro sagittal saw is used to cut the anterior cortex. Osteotomes are used to complete the osteotomy, preserving a posterior hinge. An opening spreader device is placed and opened slowly while keeping the posterior cortex intact. The new slope is maintained by use of an opening wedge osteotomy plate and screws. Allograft bone graft is packed thoroughly into the osteotomy site. Fluoroscopy is used throughout the case to assess appropriate orientation and depth of the osteotomy, as well as the final opening width. A review of 5 studies demonstrated adequate reduction in hyperextension, with a mean knee hyperextension ranging from 17° to 32° preoperatively and 0° to 7° postoperatively. Patients had significantly improved postoperative clinical outcomes compared with the preoperative state. Anterior OW PTO has been shown to be a safe method of accurately correcting tibial plateau slope for the treatment of genu recurvatum. Patients can expect correction of knee hyperextension, restoration of anatomic posterior tibial slope, decreased posterior tibial translation, and increased subjective outcome scores.

Calcific tendinitis is a common source of shoulder pain and represents pathologic deposition of calcium hydroxyapatite within rotator cuff tendon tissue, most commonly the supraspinatus tendon. Arthroscopic decompression of calcific tendinitis with possible rotator cuff repair is indicated in patients with persistent, debilitating symptoms of pain and/or dysfunction who are recalcitrant to nonoperative treatments, including corticosteroid administration, ultrasound-guided needle barbotage, and/or extracorporeal shockwave therapy. With the patient in a beach chair position, a standard diagnostic shoulder arthroscopy is performed to evaluate for concomitant pathologies. Within the subacromial space, a thorough bursectomy is performed and the area of calcium deposition is localized with a spinal needle. A scalpel may be used to create a small incision through the rotator cuff tendon in line with its fibers to promote egress of calcific debris. Surrounding tissue and loose debris are removed with an arthroscopic shaver. Following decompression, the rotator cuff repair is inspected, and if a bursal-sided or full-thickness tear is identified, an arthroscopic repair is performed with a construct individualized to the specific tear pattern. Surgical treatment conferred greater functional improvement and comparable pain reduction to nonoperative treatments in a systematic review comprised of 27 randomized trials. While the addition of a rotator cuff repair remains controversial, combined excision of calcific tendinitis with concomitant rotator cuff repair led to greater functional outcomes and pain reduction at 2-year minimum follow-up compared with isolated decompression. Calcific tendinitis within the shoulder may be treated successfully with arthroscopic decompression and subsequent repair of a residual rotator cuff defect, followed by a graduated physical rehabilitation program.

Tibial avulsion of the posterior cruciate ligament (PCL) often requires operative fixation, which frequently results in successful outcomes if identified acutely. Open or arthroscopic techniques are most commonly used. Primary surgical indications for open fixation include acute tibial avulsion of the PCL. Secondary indications include grade 2 to grade 3 posterior drawer test and radiographic posterior subluxation of the tibia. Ideally, the joint space and articular cartilage should be well preserved. In the simplified approach initially described by Burks and Schaffer, the patient is placed prone, and an inverted L-shaped incision is made over the posteromedial corner of the knee. A plane is developed between the medial head of the gastrocnemius and the semimembranosus down to the knee joint capsule. The gastrocnemius is retracted laterally to protect neurovascular structures and a vertical capsulotomy is performed. The tibial attachment of the PCL is reduced and held with K (Kirschner) wires and then fixated with screw and washer. Six months post operation, our patient achieved full active and passive range of motion with a stable posterior drawer test. He returned to work without difficulty. Multiple studies have shown success with open PCL fixation and decreased rates of arthrofibrosis when compared with arthroscopic approach. In this case, the patient did not develop arthrofibrosis. PCL tibial avulsions can be safely treated with an open approach. Contrary to other ligaments that favor reconstruction over repair, PCL avulsions may be better treated with early repair, so it is important to avoid delay in intervention. The most common complication in both open and arthroscopic approaches is arthrofibrosis, which is less common in the open approach. Early range of motion is encouraged to prevent arthrofibrosis. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.

Failure rate of meniscal repair can reach 25%. Multiple techniques have been used to increase meniscal healing, notably biological augmentation techniques. One of them is fibrin clot–augmented meniscal repair, which will be described in this video. This technique is indicated mainly for the lesions with a high failure rate. This includes large, horizontal, and radial tears and even for meniscal cysts, especially in a stable knee. This technique can also be used in revision meniscal suture when failure is no longer an option. Fibrin clot is prepared from sterile peripheral venous blood from the patient. A plastic syringe is used to stir the blood in a sterile glass container. The fibrin clot is then formed and washed rigorously with saline solution. Rolling the fibrin clot which is fixed to the syringe allows to give the fibrillar aspect of the clot. The formed fibrin clot is now solid enough to be manipulated and can be fixed to a vicryl suture thread allowing it to enter the knee and be fixed inside the meniscal lesion. The clot is wrapped inside the meniscal lesion with inside-out or outside-in suture technique. We used this technique for multiple types of lesions, like bucket handle meniscal tear, horizontal meniscal cleavage, parrot beak tear, and even in lesions within white-white zone. The postoperative protocol is the same as standard inside-out meniscal repair. This technique has been used in the literature with promising results. The fibrin clot–augmented meniscal repair is a demanding but promising technique. We need further follow-up to confirm its effectiveness.

Anterior cruciate ligament (ACL) repair has historically had poor outcomes and fell out of favor in the 1980s with the majority of surgeons opting to do an ACL reconstruction instead due to the high failure rate. The Bridge-Enhanced ACL Restoration or BEAR technique utilizes a de-cellularized, bovine-derived, type I collagen implant to aid in the ACL repair. The device is implanted to augment the healing of the ACL. The BEAR technique is indicated to augment ACL repair in cases of complete rupture where there is a residual tibial stump of sufficient length and good tissue quality. In our experience to date, patients undergoing an ACL repair with BEAR recover range of motion quickly and have less quadriceps atrophy and less postoperative swelling than those undergoing ACL reconstruction requiring autograft harvest. We will continue to follow up our patient cohort to assess for re-rupture rate as they return to sport. The BEAR technique is a promising development that enables ACL repair as an alternative option to reconstruction. This article describes our approach including tips and tricks to successfully perform this procedure. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.

The ischial tuberosity apophysis serves as an attachment site for the hamstring muscle complex in the pediatric pelvis. Once the apophysis begins to ossify around age 13 to 15 years, decreasing elasticity makes the physis the weakest part of the hamstring attachment to the pelvis. An avulsion injury of the hamstring muscle group in the adolescent therefore results in a fracture in the adolescent and is the functional equivalent to a 3-tendon proximal hamstring injury in an adult. Ischial tuberosity fractures have a higher rate of non-union than other pelvic apophyseal injuries. Endoscopic surgery offers the advantage of smaller incisions, reduced wound complications, and expedited recovery compared with an open procedure. Controversy exists over which fractures benefit from surgical fixation. Patients with an ischial tuberosity avulsion fracture that is displaced more than 20 mm or that remains symptomatic despite at least 3 months of conservative management are common indications for surgery. The patient is positioned in the prone position and under fluoroscopic guidance 2 endoscopic portals are created. The sciatic nerve is visualized, neurolysis performed, and then protected throughout the remainder of the case. The ischial tuberosity is located along with the avulsed apophysis and hamstring tendon. The bony surfaces are prepared. The fracture fragment is reduced and 3 partially threaded cannulated screws are percutaneously passed across the fracture. The interval between the semimembranosus and conjoined tendons was closed with a suture. There are no results published specific to this technique. Outcome papers are lacking, but cohort studies show significant displacement increases risk for non-union. Displaced ischial tuberosity fractures are also thought to risk sciatic nerve irritation and decreased hamstring strength. Recent advancements in periarticular endoscopic surgery of the hip have enabled this historically open procedure to be performed in a minimally invasive fashion. This technique achieves robust fixation of the avulsed fragment and the benefits of anatomic repair of the hamstring origin while avoiding the larger incision and soft tissue dissection required for an open procedure. In time, this technique may become standard of care much like other sports medicine procedures which have transitioned from open to arthroscopic with the development of suitable tools and techniques.

Managing patients with recurrent anterior shoulder instability and glenoid bony deficiency remains a challenge. Multiple graft options, including iliac crest, distal clavicle, coracoid, and distal tibia allograft have been used. There is a growing body of evidence that supports distal tibia allograft for glenoid restoration in patients with shoulder instability due to its ability to restore the articular surface as well as the glenoid depth and curvature. Surgical indications for anterior glenoid reconstruction with distal tibia allograft combined with open capsular shift include patients with recurrent shoulder instability and glenoid bone loss. A deltopectoral interval is utilized and the subscapularis is split in lines with its fibers. The subscapularis and capsule are split together in a horizontal fashion and tagged together. Any prior hardware is then removed utilizing appropriate removal sets, a burr, and a broken screw set if necessary. The anterior glenoid is then prepared and the defect is measured. Bone marrow aspirate is then harvested from the proximal humerus using a vortex needle. The distal tibia allograft is then cut to size and prepared utilizing pulsed lavage, pressurized sterile carbon dioxide, and the bone marrow aspirate. The allograft is then fixed with solid stainless steel 3.5-mm cortical screws with washers. The medial, glenoid based capsular repair it completed by placing 1.8-mm knotless FiberTak anchor at the bottom of the distal tibia allograft. A free needle is utilized to place a horizontal mattress stitch from the anchor to the inferior capsule, which is then loaded onto a shuttling suture, to repair it to the anterior inferior glenoid. A knotless anchor is then placed right off the chondral margin of the humeral head, and this is used to repair both the capsule and subscapularis in the correct position by passing through both inferior and superior leaflets. This is then loaded onto the knotless anchor and reduced, which shifts the subscapularis and capsule laterally. The remainder of the subscapularis split is then closed. Patients are then placed in a sling with an abduction pillow with no shoulder range of motion for 6 weeks. They can then progress their therapy with a goal of returning to sport at 6 months. Several large systemic reviews have shown that return to sport rates after anterior glenoid reconstruction range between 80% and 90%, with returning to the same level of play in the 70% range. Anterior glenoid reconstruction utilizing distal tibia allograft combined with an open capsular shift is a durable surgical option for patients presenting with shoulder instability and glenoid bone loss.

Multiple graft options, including iliac crest, distal clavicle, coracoid, and distal tibia allograft have been used. There is a growing body of evidence that supports distal tibia allograft for glenoid restoration in patients with shoulder instability due to its ability to restore the articular surface as well as the glenoid depth and curvature. Surgical indications for anterior glenoid reconstruction with distal tibia allograft combined with open capsular shift include patients with recurrent shoulder instability and glenoid bone loss. A deltopectoral interval is utilized and the subscapularis is split in lines with its fibers. The subscapularis and capsule are split together in a horizontal fashion and tagged together. Any prior hardware is then removed utilizing appropriate removal sets, a burr, and a broken screw set if necessary. The anterior glenoid is then prepared and the defect is measured. Bone marrow aspirate is then harvested from the proximal humerus using a vortex needle. The distal tibia allograft is then cut to size and prepared utilizing pulsed lavage, pressurized sterile carbon dioxide, and the bone marrow aspirate. The allograft is then fixed with solid stainless steel 3.5-mm cortical screws with washers. The medial, glenoid based capsular repair it completed by placing 1.8-mm knotless FiberTak anchor at the bottom of the distal tibia allograft. A free needle is utilized to place a horizontal mattress stitch from the anchor to the inferior capsule, which is then loaded onto a shuttling suture, to repair it to the anterior inferior glenoid. A knotless anchor is then placed right off the chondral margin of the humeral head, and this is used to repair both the capsule and subscapularis in the correct position by passing through both inferior and superior leaflets. This is then loaded onto the knotless anchor and reduced, which shifts the subscapularis and capsule laterally. The remainder of the subscapularis split is then closed. Patients are then placed in a sling with an abduction pillow with no shoulder range of motion for 6 weeks. They can then progress their therapy with a goal of returning to sport at 6 months. Several large systemic reviews have shown that return to sport rates after anterior glenoid reconstruction range between 80% and 90%, with returning to the same level of play in the 70% range. Anterior glenoid reconstruction utilizing distal tibia allograft combined with an open capsular shift is a durable surgical option for patients presenting with shoulder instability and glenoid bone loss.

Blood flow restriction (BFR) is a training tool that involves wearing a tourniquet or occlusive device during exercise. Data support that low-load training with BFR may produce muscle hypertrophy similar to standard high-load training. Because of the weight-bearing and range of motion (ROM) restrictions after meniscal repair, patients encounter substantial atrophy of lower extremity musculature. We perform BFR for these patients to limit atrophy postoperatively with the goal of facilitating their return to prior function and sports. We incorporate BFR in the postoperative rehabilitation protocol for patients undergoing meniscal repair not involving the root. Patients with the following are excluded: acute or severe cardiac disease, peripheral vascular disease, blood pressure over systolic 180 mm Hg or diastolic 100 mm Hg, hemophilia, thrombophlebitis or history of deep vein thrombosis, severe anemia, and sickle cell disease. An automated BFR device calculates the patient’s limb occlusion pressure (LOP) and titrates to 50% to 80% of LOP for lower extremity exercises. Exercise parameters typically consist of 4 sets of each exercise, totaling 75 repetitions, with 30-second interset rest. Patients undergo a standard 3-phase postoperative rehabilitation protocol. Phase I (weeks 0-6): Patients are nonweightbearing, may be either footflat weightbearing or partial weightbearing at the surgeon’s, with ROM restricted 0 to 90 in a hinge knee brace throughout the phase. Exercises include quadriceps sets with neuromuscular electrical stimulation and straight leg raises and short/long arcs quadriceps. Phase II (weeks 7-8): Patients progress to weightbearing and ROM as tolerated and begin exercises including double mini squats, hamstring curls, double leg press, and double leg heel raises. Phase III: (weeks 9+): Patients perform double and single leg bridges, double leg bridges on ball with knee band, squats, single leg press, and single leg heel raises, all with the goal of returning to sports. Prior systematic review data demonstrate low-load training with BFR increases muscle strength and induces hypertrophy relative to low-load training alone. No significant differences for Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales between BFR training group and control group. BFR training may facilitate postoperative recovery in patients undergoing meniscal repair surgery by helping mitigate muscular atrophy.

Anatomically, native posterior tibial slope (PTS) ranges from 6° to 10° and have significant effects on cruciate ligament stability. PTS <6° is correlated with increased posterior tibial translation (PTT) and force on the posterior cruciate ligament (PCL), predisposing individuals to PCL injuries and an increased risk of PCL graft attenuation. In rare cases, a reverse tibial slope can occur (<0°) as a result of trauma, physeal arrest, or abnormal development. This results in increased PTT and can lead to posterior tibial subluxation. Reverse tibial slopes in patients can be treated with an anterior opening wedge proximal tibial osteotomy, which increases the PTS to a more anatomic position. Biplanar anterior opening wedge proximal tibial osteotomies are indicated in patients with a reverse tibial slope both with the absence of PCL insufficiency or in conjunction with PCL reconstruction. Under fluoroscopic imaging, 2 guide pins were placed perpendicular to the tibial shaft. An oscillating saw and osteotomes completed the osteotomy in line with the guide pins with the posterior cortex remaining intact. The osteotomy site was slowly opened with a spreader device to 9 mm until the posterior drawer was such that the palpable step-off between the anterior aspect of the medial femoral condyle and the medial tibial plateau was comparable to the contralateral knee. Due to the patient having slight valgus coronal plane alignment, an opening-wedge posteriorly sloped plate was then placed anterolaterally and fixed while wedges held the osteotomy open. Biplanar anterior opening wedge osteotomies correct a flattened PTS and reverse tibial slope, and coronal malalignment, and has been shown to decrease PCL laxity, preventing future PCL failure. Biomechanical studies have shown that decreased tibial slope is correlated with an increased risk of PCL injury and PCL graft failure. In patients with reverse tibial slope, experienced instability can mimic PCL insufficiency despite there being no ligamentous damage. We describe a technique that corrects reverse tibial slope and with a discussion of surgical pearls and pitfalls. This technique restores anatomic position and normal function of the knee while correcting the sagittal malalignment that could lead to future injuries. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication. If the individual may be identifiable, the author(s) has included a statement of release or other written form of approval from the patient(s) with this submission for publication.
