Aulexmed BL-42001

Product Code: OTAP-OBAS-3636

Thigh and calf straps are there to stop the brace sliding down the leg.

A dial hinge on dual metal uprights sets the knee's range between 10 and 120 degrees or locks it anywhere from 10 to 90 degrees, while thigh and calf straps keep the brace in position. It comes in one black size.

Aulexmed classifies the BL-42001 as a knee immobiliser brace, though its dial hinge also allows controlled movement. The datasheet lists thigh and calf straps to prevent slipping and provide secure fixation, a dial-type hinge for flexion and extension control and angle locking, and dual metal hinges for stable support and precise angle adjustment. The adjustable range is 10 to 120 degrees, with locking available from 10 to 90 degrees. Indications include general knee instability, postoperative fixation for ligament, meniscus, or patellar fracture surgery, knee sprains, strains, or muscle imbalance, recovery after ACL or MCL surgery, and knee injuries and rehabilitation. One size is listed in black.

Who the brace suits depends on the protocol. Surgeons who want the knee held at a set angle and then allowed a widening range can use the dial to follow that plan. Two points narrow the group. The lock range starts at 10 degrees, and no setting at 0 degrees is listed, so protocols that need the knee held fully straight should confirm the hinge first. And for ACL reconstruction, systematic reviews have found no longer-term benefit from routine postoperative bracing, so the brace belongs where the surgeon specifically wants controlled movement.

Photography shows long black thigh and calf sections joined by the hinged uprights, a grey dial with red markings at the knee, four straps and a strap rising from the top of the thigh section that appears to act as a suspender. The suspender is not described in writing.

No brace length, weight or circumference range is published, and hinge increments are not stated. Medigear.uk lists the BL-42001 for business buyers worldwide; before ordering, ask the seller for the fit range, whether a 0-degree lock is available, the hinge increments and the declaration of conformity.

Orthopaedic surgical units can use the BL-42001 after knee procedures where the surgeon wants the knee held at a set angle and then allowed a controlled range. Meniscal repair, collateral ligament injuries and some fracture fixations are typical examples, with the dial set to the surgeon's protocol at each review.

Patellar fracture and extensor mechanism pathways need care. The datasheet lists locking from 10 degrees, and many of those protocols begin with the knee held fully straight, so the seller must confirm whether a 0 degree lock is available before the brace is used there.

ACL reconstruction pathways are listed on the datasheet, but systematic reviews and a 2025 meta-analysis found no longer-term benefit from routine postoperative bracing. Services should reserve the brace for cases where the surgeon has a specific reason to control movement.

Fracture clinics and emergency departments may use it for knee sprains and ligament injuries where a hinged brace is wanted, with the range set by the treating clinician. The thigh and calf straps should be checked so the hinge stays level with the knee.

Physiotherapy services work with the adjustable range as patients progress. Recording the dial settings at each session keeps the whole team aligned, and a check of hinge position should be routine.

Any service discharging adults with the knee immobilised needs the VTE risk assessment described in NICE NG89. NHS procurement routes ask for the device class and the declaration of conformity, and public buyers in other countries ask for the equivalent. The conformity documentation those procurement routes require is issued by the manufacturer and provided by the seller.

Lock or allow controlled movement

The dial hinge locks from 10 to 90 degrees and allows a range from 10 to 120 degrees. One brace can follow a staged protocol.

Dual metal hinges

Metal hinges on both sides are listed for stable support and precise angle adjustment. The knee is controlled from medial and lateral sides.

Straps that resist slipping

Thigh and calf straps are listed to prevent slipping and give secure fixation. The hinge stays near the knee joint.

A suspender strap in photography

Photography shows a strap rising from the thigh section. It appears designed to help hold the brace up on the leg.

Dial adjustment

The dial-type hinge allows flexion and extension limits to be set by hand. Changes at review are quick.

One size to stock

A single size is listed. Stock management is simple, provided the fit range suits the patients seen.

Long thigh and calf sections

Photography shows long sections above and below the knee. That gives the hinge leverage along the leg.

No electrical parts

The brace has no powered components. There is nothing to charge and no electrical safety testing.

Dial-type hinge

The dial hinge controls flexion and extension and locks the angle in place. Photography shows a grey dial with red markings.

Adjustable range

The range adjusts from 10 to 120 degrees. Increments are not published.

Angle locking

The hinge locks at angles from 10 to 90 degrees. A 0-degree setting is not listed.

Dual metal hinges

Metal hinges on both sides provide stable support and precise angle adjustment. Their material grade is not published.

Thigh and calf straps

Straps at the thigh and calf prevent slipping and give secure fixation. Photography shows four straps.

Suspender strap

Photography shows a strap rising from the top of the thigh section. It is not described in writing.

One size

A single size is listed. No circumference range or length is published.

Black finish

The brace is listed in black. Photography shows a grey and red dial.

Listed indications

Listed indications include knee instability, postoperative ligament, meniscus, and patellar fracture fixation, sprains and strains, ACL and MCL recovery, and rehabilitation.

No listed liner

No liner or padding is described. Confirm interior details with the seller.

Laterality

The datasheet does not state whether the brace fits either leg. Confirm with the seller.

Unpowered construction

The brace contains no electrical components. No electrical safety standard applies.

The BL-42001 is a hinged knee brace that can lock the knee from 10 to 90 degrees or allow a range from 10 to 120 degrees, using a dial on dual metal hinges, with thigh and calf straps and a suspender strap to hold it in place. It suits surgeon-led protocols that want staged, controlled movement. Two limits matter: no 0 degree lock is listed, and routine bracing after ACL reconstruction is not supported by the evidence. Medigear.uk lists the BL-42001 for business buyers worldwide and can arrange delivery and quotations. Request the fit range, 0 degree lock availability, hinge increments, laterality and the declaration of conformity from the seller at quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

The datasheet lists general knee instability, postoperative fixation for ligament, meniscus or patellar fracture surgery, knee sprains, strains or muscle imbalance, support after ACL or MCL surgery, and knee injuries and postoperative rehabilitation. These cover a wide range of patients. The treating surgeon or physiotherapist decides whether the brace fits each patient's protocol.

It can work as both. The dial-type hinge allows an adjustable range of 10 to 120 degrees and can lock the knee at angles from 10 to 90 degrees. That lets the same brace hold the knee still in the early weeks and allow controlled movement later, if the protocol calls for it.

The datasheet lists locking from 10 to 90 degrees, and it doesn't mention a 0-degree setting. Some postoperative protocols, particularly after repairs of the tendons at the front of the knee or fixation of a patellar fracture, call for the knee to be held fully straight at first. Confirm with the seller whether the hinge can lock at 0 degrees before using the brace on those pathways.

A systematic review of seven trials covering 390 ACL reconstructions found no significant longer-term differences in outcome between patients who wore a knee brace after surgery and those who did not. A 2025 meta-analysis of 11 studies and 785 participants concluded that routine brace use after ACL reconstruction is not warranted. ACL recovery is listed on the datasheet, so the brace is best reserved for cases where the surgeon specifically wants movement controlled.

The datasheet lists one size but gives no thigh or calf circumference range and no brace length. Adjustable straps usually allow a range of leg sizes, but the limits are not published. Fit a sample on a very slim and a very large leg to see whether the brace stays centred on the knee.

The datasheet lists thigh and calf straps to prevent slipping and give secure fixation. The photos show four straps and an additional strap rising from the top of the thigh section, which appears to act as a suspender. The hinge must stay level with the knee joint for the angle settings to mean anything, so check its position at every review.

The dial-type hinge controls flexion and extension and locks the angle. Dual metal hinges are listed for stable support and precise angle adjustment. The increments between settings and the locking method aren't published. Please request the instructions for use before training staff.

The datasheet does not say whether the brace fits the left or the right leg. Hinged knee braces are often universal, but confirm with the seller before stocking.

Yes, where an adult is discharged with the knee immobilised. NICE quality standard QS201 expects a documented VTE risk assessment in line with NG89 for people aged 16 and over with lower limb immobilisation. That applies whichever brace is chosen.

No cleaning method is published, and reuse between patients is not addressed. Hinged braces are sometimes reissued where the manufacturer supplies replacement liners and a cleaning method, but this datasheet mentions neither. Treat each brace as a single-patient issue unless the manufacturer's instructions state otherwise.

Request the declaration of conformity, naming the legal manufacturer, the device class and the standards applied. A knee brace of this type is typically Class I under UK MDR 2002, confirmed against the declaration at order. No CE or UKCA mark appears on the supplied sheet, and the manufacturer's website also uses the name Benli Medical, so confirm the legal manufacturer and the UK Responsible Person in writing. Great Britain accepts CE-marked devices under transitional arrangements that the MHRA consulted on extending in 2026. Conformity requirements differ by destination market, and the seller confirms what applies where the brace is going.

Protocols that require the knee to be locked fully straight should not use it until a 0-degree lock is confirmed. The evidence does not support routine use after ACL reconstruction. Patients whose legs fall outside the unpublished fit range will not keep the hinge centred. Patients with reduced sensation need close skin checks under the straps.
